Foreword

Foreword
Recognizing the problem of global climate change, the World Meteorological Organization (WMO) and theUnited Nations Environment Programme (UNEP) co-established in 1988 the Intergovernmental Panel on
Climate Change (IPCC). One of the IPCC’s activities is to support the UN Framework Convention on Climate
Change (UNFCCC) through its work on methodologies for national greenhouse gas inventories.
The 2013 Revised Supplementary Methods and Good Practice Guidance Arising from the Kyoto Protocol (KP
Supplement) provides supplementary methods and good practice guidance for estimating anthropogenic
greenhouse gas emissions by sources and removals by sinks resulting from land use, land-use change andforestry (LULUCF) activities under Article 3, paragraphs 3 and 4, of the Kyoto Protocol for the second
commitment period. It revises and updates Chapter 4 of the Good Practice Guidance for Land Use, Land-Use
Change and Forestry (GPG-LULUCF) 1 . This provides supplementary methods and good practice guidance
related to LULUCF activities based on the general greenhouse gas inventory guidance provided in its otherchapters and the rules governing the treatment of LULUCF activities in the first commitment period of the Kyoto
Protocol.
In December 2011, the Parties to the Kyoto Protocol to the UNFCCC invited the IPCC to review and, if
necessary, update supplementary methodologies for estimating anthropogenic greenhouse gas emissions bysources and removals by sinks resulting from LULUCF activities under Article 3, paragraphs 3 and 4, of the
Kyoto Protocol, related to the annex to decision 2/CMP.72, on the basis of, inter alia, Chapter 4 of the GPGLULUCF. In response, the IPCC at its 35th Session in Geneva (June 2012) decided to produce the KP
Supplement by October 2013 agreeing the Terms of Reference, Table of Contents and work plan. According to
the work plan, the work on the production of the KP Supplement was carried out by the Task Force on National
Greenhouse Gas Inventories (TFI) in 2012 and 2013. The Overview Chapter of the KP Supplement was adopted
and the entire report was accepted at the 37th Session of IPCC held in Batumi, Georgia (October 2013).
The development of the KP Supplement has been made possible by the enormous contribution made by the
Coordinating Lead Authors, Lead Authors and Contributing Authors – a total of 71 authors worldwide – throughtheir exceptional knowledge, expertise and hard work. A total of nine Review Editors oversaw the IPCC review
process. We wish to thank them for their commitment, time and efforts in preparing this report. As with all the
IPCC Methodology Reports, this report has built upon the work of the previous IPCC Methodology Reports
including the GPG-LULUCF and the 2006 IPCC Guidelines for National Greenhouse Gas Inventories (2006
IPCC Guidelines)3. We are pleased to acknowledge our debt to all those who contributed to those reports.
The Steering Group, consisting of IPCC TFI Co-Chairs Takahiko Hiraishi (Japan) and Thelma Krug (Brazil)
together with Rizaldi Boer (Indonesia), Sergio González Martineaux (Chile), Jim Penman (UK), Robert Sturgiss(Australia), Nalin Srivastava (TFI Technical Support Unit (TFI-TSU)), Kiyoto Tanabe (TFI-TSU) andWashington Zhakata (Zimbabwe), has guided the development of this report, ensuring its internal consistency aswell as consistency with the 2006 IPCC Guidelines and the GPG-LULUCF. We would wish to sincerely thankthem for their considerable efforts in leading the task and providing strategic guidance. We express a highappreciation to the IPCC Task Force Bureau on National Greenhouse Gas Inventories (TFB) for their overall
guidance and oversight.
The Lead Author meetings were held in Kobe (Japan); Wollongong (Australia); Oslo (Norway) and Chiang Mai(Thailand). We would like to thank the host countries and agencies for organising these meetings. We would also
like to thank all governments that supported authors and reviewers for their contribution, without which the
production of this report might not have been possible.

A comprehensive review is an important element of the IPCC process. The KP Supplement underwent tworounds of review, followed by a round of submission of written comments by governments in 2013. The reviewof the First Order Draft received over 2500 comments from 93 expert reviewers while the review of Second
Order Draft received more than 1600 comments from expert reviewers and 18 governments. The Final Draft
received over 300 comments from 14 governments. The review comments from both governments and expert
reviewers, have contributed greatly to the quality of the final report and we wish to sincerely thank them for theirtime and efforts.
In addition, the TFI-TSU (Head: Kiyoto Tanabe; Deputy Head; Nalin Srivastava; Programme Officers:
Baasansuren Jamsranjav, Maya Fukuda and Tiffany Troxler; Administrative Assistant: Koh Mikuni; Secretary:
Eriko Nakamura; and IT Officer: Toru Matsumoto) has made an invaluable contribution to the development of
the KP Supplement by providing technical and organisational support to the project. Apart from working
tirelessly to organise meetings and reviews, they worked extensively with the authors, especially in editing of thedrafts and preparation of the final version, to deliver high quality outputs in a very challenging time frame. We
wish to congratulate them and sincerely thank them for their exemplary work. Thanks are also due to the former
TSU Head, Simon Eggleston, who led the TSU work on the development of the KP Supplement in its earlystages. We would also like to express our gratitude to the Government of Japan, for its generous support of the
TFI-TSU, without which this report might not have been completed. We would also like to thank the Institute for
Global Environmental Strategies (IGES) for hosting the TFI-TSU.
We would also like to thank the IPCC Secretariat, led by the Secretary, Renate Christ, for their continued
assistance and support in enabling this project to meet its tight deadlines.
Finally we would like to thank the IPCC Chair Rajendra Pachauri for his support and guidance.

Overview

1 INTRODUCTION
The 2013 Revised Supplementary Methods and Good Practice Guidance Arising from the Kyoto Protocol (KP
Supplement) provides supplementary methods and good practice guidance 1 for estimating and reporting
anthropogenic greenhouse gas (GHG) emissions and removals resulting from land use, land-use change andforestry (LULUCF) activities under Article 3.3 and Article 3.4 of the Kyoto Protocol for the second
commitment period, 2013-2020.
The KP Supplement was requested by the Decision2 on LULUCF of the United Nations Framework Convention
on Climate Change (UNFCCC) Conference of the Parties Serving as the Meeting of the Parties to the Kyoto
Protocol, taken in Durban in 2011. The KP Supplement updates Chapter 4 of the Good Practice Guidance forLand Use, Land-Use Change and Forestry 3 (GPG-LULUCF), which provides supplementary methods for
LULUCF activities for the first commitment period, 2008-2012. The structure and wording of Chapter 4 havebeen maintained wherever possible4.
Under the provisions of Articles 7.1 and 7.2 of the Kyoto Protocol, Parties are required to incorporate, in theirannual GHG inventories and national communications, supplementary information relating to anthropogenic
emissions by sources and removals by sinks of CO2 and other greenhouse gases associated with LULUCF
activities under Article 3.3 and Article 3.4 of the Kyoto Protocol 5. For the second commitment period, theactivities included under Article 3.3 are Afforestation, Reforestation, and Deforestation since 1990, which
remain mandatory. Activities under Article 3.4 are Forest Management, which becomes mandatory for thesecond commitment period, and elective activities, namely Cropland Management, Grazing Land Management,
Revegetation and Wetland Drainage and Rewetting6.

1

Supplementary methods are additional guidance to produce the supplementary information needed in greenhouse gas
inventories to meet the LULUCF rules for the Kyoto Protocol. Compliance with good practice means neither over- norunderestimates so far as can be judged, and that uncertainties are reduced so far as is practicable.

The activities are defined as follows:“Afforestation” is the direct human-induced conversion of land that has not been forested for a period of at least 50 years
to forested land through planting, seeding and/or the human-induced promotion of natural seed sources.
“Reforestation” is the direct human-induced conversion of non-forested land to forested land through planting, seeding
and/or the human-induced promotion of natural seed sources, on land that was forested but that has been converted to
non-forested land. For the first commitment period, reforestation activities will be limited to reforestation occurring on
those lands that did not contain forest 31 December 1989.
“Deforestation” is the direct human-induced conversion of forested land to non-forested land.
“Forest management” is a system of practices for stewardship and use of forest land aimed at fulfilling relevant ecological(including biological diversity), economic and social functions of the forest in a sustainable manner.
“Cropland management” is the system of practices on land on which agricultural crops are grown and on land that is set
aside or temporarily not being used for crop production.
“Grazing land management” is the system of practices on land used for livestock production aimed at manipulating theamount and type of vegetation and livestock produced.

2013 Revised Supplementary Methods and Good Practice Guidance Arising from the Kyoto Protocol

Overview

The KP Supplement builds on methods and guidance provided by the 2006 IPCC Guidelines for National
Greenhouse Gas Inventories (2006 IPCC Guidelines) and will be used in conjunction with the 2006 IPCC
Guidelines and with the 2013 Supplement to the 2006 IPCC Guidelines for National Greenhouse Gas
Inventories: Wetlands (Wetlands Supplement).

2 BACKGROUNDThe UNFCCC Conference of the Parties serving as the Meeting of the Parties to the Kyoto Protocol at its
seventh session (CMP 7), held in December 2011 in Durban, South Africa, invited the IPCC to:…review and, if necessary, update supplementary methodologies for estimating
anthropogenic greenhouse gas emissions by sources and removals by sinks resulting fromland use, land-use change and forestry activities under Article 3, paragraphs 3 and 4, of the
Kyoto Protocol, related to the annex to this decision, on the basis of, inter alia, chapter 4 of
its Good Practice Guidance for Land Use, Land-Use Change and Forestry7.
In response to the UNFCCC’s invitation, the need to update Chapter 4 was considered at the IPCC Scoping
Meeting to consider the Invitation from UNFCCC CMP 7 that took place in Geneva in May 2012.
The IPCC at its 35th Session decided to produce the KP Supplement and agreed Terms of Reference, a Table ofContents and a Work Plan8. The Terms of Reference specified that the revision of Chapter 4 of the GPGLULUCF should be consistent with the 2006 IPCC Guidelines and with the decisions of the COP and CMP, thatit should not revise or replace the 2006 IPCC Guidelines, and that it should maintain the structure and content of
the existing Chapter 4 of the GPG-LULUCF.

3 THE NEED TO UPDATE CHAPTER 4 OF GPGLULUCF
Chapter 4 of the GPG-LULUCF provides supplementary methods and good practice guidance related to
LULUCF activities, based on the general GHG inventory guidance provided in other chapters of the GPGLULUCF and the rules governing the treatment of LULUCF activities in the first commitment period of Kyoto
Protocol9. The need to review and update Chapter 4 of the GPG-LULUCF for the second commitment periodarises because:First, the rules for reporting and accounting of LULUCF activities for the second commitment period under the
Kyoto Protocol differ in some respects from the rules for the first commitment period.
Second, updating is needed in the light of the CMP decision to use the 2006 IPCC Guidelines for the second
commitment period under the Kyoto Protocol10.
The new rules for the treatment of LULUCF in the second commitment period of the Kyoto Protocol agreed by
CMP 7 contain, amongst other things, new provisions, which are not covered in the existing Chapter 4 of the
GPG-LULUCF, on Forest Management; natural disturbances in Forest Management and Afforestation and
Reforestation areas; Harvested Wood Products; and Wetland Drainage and Rewetting. Table 1 summarises the“Revegetation” is a direct human-induced activity to increase carbon stocks on sites through the establishment ofvegetation that covers a minimum area of 0.05 hectares and does not meet the definitions of afforestation and reforestation
contained here.
“Wetland drainage and rewetting” is a system of practices for draining and rewetting on land with organic soil that covers
a minimum area of 1 hectare. The activity applies to all lands that have been drained since 1990 and to all lands that havebeen rewetted since 1990 and that are not accounted for under any other activity as defined above, where drainage is the
direct human-induced lowering of the soil water table and rewetting is the direct human-induced partial or total reversalof drainage.

Products shall be on the basis of the change in the Harvested Wood Products
pool during the second and subsequent commitment periods, estimated using
the first-order decay function with default half-lives provided in the Decision

Parties may use country-specific half-lives as an alternative to thosespecified in Decision 2/CMP.7, or to account for Harvested Wood Products
in accordance with the definitions and estimation methodologies in the mostrecently adopted IPCC guidelines, and any subsequent clarifications agreed
by the COP, if verifiable and transparent activity data are available and themethodologies used are at least as detailed or accurate as those specified in
the Decision21.
Harvested Wood Products resulting from Deforestation; solid waste disposalsites (where carbon dioxide emissions are separately accounted for); andwood harvested for energy purposes shall be accounted for on the basis of
instantaneous oxidation22.
Emissions that occur in the second commitment period from Harvested
Wood Products removed from forests prior to the start of the second
commitment period shall also be accounted for. Emissions from Harvested
Wood Products already accounted for during the first commitment period on
the basis of instantaneous oxidation shall be excluded23.
Parties may choose not to account for the emissions from Harvested Wood
Products from forests prior to the start of the second commitment period if
the Forest Management Reference Level is based on a projection and shallensure consistency in the treatment of the Harvested Wood Products pool inthe second commitment period24.
Natural disturbances are defined as non-anthropogenic events or nonanthropogenic circumstances. For the purposes of this decision, these eventsor circumstances are those that cause significant emissions in forests andare beyond the control of, and not materially influenced by, a Party. Thesemay include wildfires, insect and disease infestations, extreme weather
events and/or geological disturbances, beyond the control of, and notmaterially influenced by, a Party. These exclude harvesting and prescribedburning25.

Parties may include in the accounting of Forest Management under Article 3.4
anthropogenic greenhouse gas emissions by sources and removals by sinks
resulting from the harvest and conversion of forest plantations, accounted forunder Forest Management, to non-forest land, provided that all of the following
requirements are met32:
 The forest plantation was first established through direct human-induced
planting and/or seeding of non-forest land before 1 January 1990, and, if reestablished, that this last occurred on forest land through direct humaninduced planting and/or seeding after 1 January 1960.
 A new forest of at least equivalent area as the harvested forest plantation isestablished through direct human-induced planting and/or seeding of nonforested land that did not contain forest on 31 December 1989.
 A debit under Article 3.4 would be generated if the newly established forest
does not reach at least the equivalent carbon stock that was contained in theharvested forest plantation at the time of harvest, within the normal
harvesting cycle of the harvested forest plantation.
 All lands and associated carbon pools subject to the provision shall beidentified, monitored and reported, including the georeferenced location andthe year of conversion and accounted for as Forest Management under
Article 3.4 and not under Article 3.3.



Wetland Drainage and Rewetting was added as a new elective activity under
Article 3.4 by Decision 2/CMP.733.
Wetland Drainage and Rewetting is defined as a system of practices for draining
and rewetting on land with organic soil that covers a minimum area of 1
hectare. The activity applies to all lands that have been drained since 1990 andto all lands that have been rewetted since 1990 and that are not accounted forunder any other activity as defined in this annex where drainage is the direct
human-induced lowering of the soil water table and rewetting is the direct
human-induced partial or total reversal of drainage34.
Estimation methodologies for Wetland Drainage and Rewetting shall be basedon the most recently adopted or encouraged IPCC guidelines and any subsequentclarifications agreed by the COP35.
Accounting for Wetland Drainage and Rewetting shall be done on a net-net
basis36, while avoiding double counting37.

4 STRUCTURE AND CONTENT OF THE KP
SUPPLEMENTThe KP Supplement maintains the structure and general content of Chapter 4 in GPG-LULUCF. Wherevernecessary, it replaces references to the GPG-LULUCF with those of 2006 IPCC Guidelines, and adds additional
material to existing sections or adds new sections where required by the new rules. It updates Chapter 4 of the
GPG-LULUCF to be consistent with the 2006 IPCC Guidelines but does not revise or replace the 2006 IPCC
Guidelines.
There are two chapters in the KP Supplement corresponding to the first two main sections of Chapter 4 of the
GPG-LULUCF:

Chapter 1: Introduction
This chapter deals with overview of steps to estimate and report supplementary information for Article 3.3 and3.4 activities; general rules for categorisation of lands under Articles 3.3 and 3.4 activities; and the relationshipbetween Annex I national inventories and Article 6 projects40. Updates include:(i)Changes to steps for reporting supplementary information and the general rules for categorisationof lands under Articles 3.3 and 3.4 lands including the reporting hierarchy of activities, due toForest Management being made a mandatory activity and inclusion of Wetland Drainage andRewetting as an elective activity under Article 3.4; and(ii)

Updating decision trees and figures to reflect Decision 2/CMP.7.

Chapter 2: Methods for estimation, measurement, monitoring and reporting of
LULUCF activities under Articles 3.3 and 3.4
This chapter includes generic and activity-specific methodological guidance on area identification, stratification
and reporting, and estimation of carbon stock changes and non-CO2 GHG emissions. Some new sections havebeen added and the existing guidance in Chapter 4 of GPG-LULUCF has been extensively revised and expanded
to reflect the changes stemming from Decision 2/CMP.7 and the use of the 2006 IPCC Guidelines. Main changes
include:(i)

Revision of the section on Disturbances (Section 2.3.9; Section 4.2.3.6 in Chapter 4 of GPGLULUCF) in the light of the new rules regarding the treatment of emissions from natural
disturbances in Afforestation, Reforestation and Deforestation and Forest Management lands;(ii)

Addition of new sections on Forest Management Reference Level (Section 2.7.5), TechnicalCorrections (Section 2.7.6) and Carbon Equivalent Forests (Section 2.7.7);(iii)

Addition of a new section on Harvested Wood Products (Section 2.8); and(iv)

Addition of a new section on Wetland Drainage and Rewetting (Section 2.12).

2013 Revised Supplementary Methods and Good Practice Guidance Arising from the Kyoto Protocol

O.13

Overview

5 POLICY RELEVANCEFor Kyoto Protocol reporting, The KP Supplement aims to provide guidance for the operationalization of theagreement set out in Decision 2/CMP.7. On some specific points, the KP Supplement:

provides guidance on estimating and reporting anthropogenic emissions and removals. It does not deal withaccounting, in other words, the rules by which the UNFCCC uses reported information to assess how Partiesare complying with commitments, except in so far as accounting rules need to be reflected in guidance onemissions and removals estimation and reporting. The KP Supplement aims to be consistent with thedecisions of the COP and CMP but not to extend them. The word shall is therefore used below only when
decisions are quoted directly.



provides advice on achieving transparency where, in continuing to apply the 16/CMP.1 definition of forest,
certain types of land such as fruit orchards, grazed savannas, urban trees, and some types of plantations, areexcluded, e.g. to achieve consistency with reporting to Food and Agriculture Organization of the United
Nations (FAO) and with national forest inventories.



clarifies the guidance on hierarchies between Article 3.3 and Article 3.4 activities, but maintains theprioritisation in the ordering of Deforestation under Article 3.3. This has the consequence (revealed bysecondary classification) that Deforestation land can contain trees, if it has been subsequently subject to
Afforestation and Reforestation. The approach shows transparently the sequences that have occurred.



provides guidance, for those Parties wishing to make use of the natural disturbance provisions, thatemissions and removals on lands affected by natural disturbances would need to be removed fromaccounting unless they are from salvage logging or there is land-use change. This is consistent withDecision 2/CMP.7 and reflects the difficulty in practice of separating on any particular land the emissions
and removals due to a disturbance from other emissions and removals.



avoids making judgements about rules beyond the second commitment period, for example concerning landuse change occurring after the end of the second commitment period on land to which natural disturbanceprovisions were applied, and hence emissions excluded, during the second commitment period.

1 INTRODUCTION
1.1

INTRODUCTION

The 2013 Revised Supplementary Methods and Good Practice Guidance Arising from the Kyoto Protocol (KP
Supplement) describes the supplementary methods and good practice guidance for measuring, estimating andreporting of anthropogenic greenhouse gas (GHG) emissions and removals resulting from land use, land-use
change and forestry (LULUCF) activities covered by the Kyoto Protocol (KP) for the second commitment period(CP). This document addresses activities under Article 3.3, Forest Management and elective activities under
Article 3.4. The supplementary methods and good practice guidance of this document are relevant to each Party
included in Annex I that have ratified the KP for the second CP and for other countries interested in the updated
guidance. This document does not provide good practice guidance for LULUCF projects hosted by Parties listed
in Annex B (Article 6 projects) and Afforestation/Reforestation projects hosted by Parties not listed in Annex Bof the KP (Article 12, Clean Development Mechanism or CDM projects), which are addressed in Section 4.3 of
the Good Practice Guidance for Land Use, Land-Use Change and Forestry (GPG-LULUCF).
To ensure compliance with emission limitation and reduction commitments 1 in the CP, and to meet theirreporting requirements under the Kyoto Protocol, Parties are required to provide supplementary information
related to LULUCF under the provisions of the KP2. This information is required as part of the annual National
Inventory Reports (NIR) using Common Reporting Format (CRF) tables to report GHG emissions by sources
and removals by sinks. The annual reporting requirement does not imply a need for annual measurements, but
Parties are expected to develop systems that combine measurements, models and other tools that enable them toreport on an annual basis.
The supplementary information required includes reporting emissions by sources and removals by sinks of CO2
and other specified GHGs resulting from Article 3.3 and 3.4 activities. These include activities for which
reporting is mandatory under Article 3.3, i.e. Afforestation (A), Reforestation (R) and Deforestation (D) that
occurred since 1990; and under Article 3.4, Forest Management (FM), and any other Article 3.4 activities electedby the Party. These can include: Cropland Management (CM), Grazing Land Management (GM), Revegetation(RV), and Wetland Drainage and Rewetting (WDR).3

LULUCF related requirements are outlined in Decision 16/CMP.1 and Decision 2/CMP.7 (Land use, land-use change andforestry) contained in document FCCC/KP/CMP/2005/8/Add.3, p.3 and FCCC/KP/CMP/2011/10/Add.1, p.13 respectively:“Afforestation” is the direct human-induced conversion of land that has not been forested for a period of at least 50 years
to forested land through planting, seeding and/or the human-induced promotion of natural seed sources.
“Reforestation” is the direct human-induced conversion of non-forested land to forested land through planting, seeding
and/or the human-induced promotion of natural seed sources, on land that was forested but that has been converted to
non-forested land. For the first commitment period, Reforestation activities will be limited to Reforestation occurring on
those lands that did not contain forest on 31 December 1989.
“Deforestation” is the direct human-induced conversion of forested land to non-forested land.
“Forest management” is a system of practices for stewardship and use of forest land aimed at fulfilling relevant ecological(including biological diversity), economic and social functions of the forest in a sustainable manner.
“Cropland management” is the system of practices on land on which agricultural crops are grown and on land that is set
aside or temporarily not being used for crop production.
“Grazing land management” is the system of practices on land used for livestock production aimed at manipulating theamount and type of vegetation and livestock produced.
“Revegetation” is a direct human-induced activity to increase carbon stocks on sites through the establishment ofvegetation that covers a minimum area of 0.05 hectares and does not meet the definitions of Afforestation and
Reforestation contained here.
“Wetland drainage and rewetting” is a system of practices for draining and rewetting on land with organic soil that covers
a minimum area of 1 hectare. The activity applies to all lands that have been drained since 1990 and to all lands that havebeen rewetted since 1990 and that are not accounted for under any other activity as defined above, where drainage is the
direct human-induced lowering of the soil water table and rewetting is the direct human-induced partial or total reversalof drainage.

2013 Revised Supplementary Methods and Good Practice Guidance Arising from the Kyoto Protocol

Chapter 1: Introduction

This document builds on methods and guidance provided by the 2006 IPCC Guidelines for National Greenhouse
Gas Inventories (2006 IPCC Guidelines) and it replaces Chapter 4 (except Section 4.3 on projects) of the GPGLULUCF. The structure and general content of Chapter 4 of the GPG-LULUCF have been maintained wherever
possible for reasons of consistency.
By definition good practice GHG inventories are those which do not contain overestimates or underestimates so
far as can be judged, and in which uncertainties are reduced, as far as is practicable. The words “it is goodpractice to...” indicate that the guidance that follows contributes to producing GHG inventories consistent withgood practice.
Relationship between UNFCCC and KP reporting:
The information to be reported under the KP is supplementary to the information reported under the United
Nations Framework Convention on Climate Change (UNFCCC). A Party included in Annex I to the KP does notneed to submit two separate annual inventories but is required to provide supplementary information under the
KP, within the inventory report.4 Each Party included in Annex I to the Convention which is also a Party to the
KP will be subject to the review of submitted information in accordance with relevant decisions under Article 8of the KP.
National circumstances, and specifically the technical details of the GHG reporting systems put into place byeach country, will determine the sequence in which the reporting information is compiled. In theory, it ispossible to start with the UNFCCC inventory (with the additional spatial information required for KP reporting)and expand it to the KP inventory, or it is possible to use a national system that generates the information forboth UNFCCC and KP reporting at the same time.
For example when a Party that has elected CM under Article 3.4 prepares its UNFCCC inventory for Cropland,
it is efficient to use the same geographical boundaries for stratification (Section 2.2.2). When preparing the
supplementary information to be reported under the KP, the Party would delineate those UNFCCC Croplandareas that originated from forests since 1 January 1990 (Chapter 5.3, Volume 4 of 2006 IPCC Guidelines, Land
converted to Cropland), report these under D according to Article 3.3, with the exception of those lands that havebeen cleared under the provision of Carbon Equivalent Forest Conversion (CEFC)5 which should be reported
under FM. All remaining UNFCCC Croplands will be reported under CM.
This document covers supplementary estimation and inventory reporting requirements needed for accounting
under the KP in the second CP. Estimation refers to the way in which inventory estimates are calculated,
reporting refers to the presentation of estimates in the tables or other standard formats used to transmit inventory
information, and accounting refers to the way the reported information is used to assess compliance withcommitments under the KP. This document does not address the implementation of accounting rules as agreed in
relevant decisions of the Conference of the Parties serving as the Meeting of the Parties (CMP) of the KP (suchas caps on accounted removals from FM, annual vs. CP accounting and other specific provisions related toaccounting).
In this document the terms “units of land” and “land” are combined. Chapter 4 of the GPG-LULUCF uses theformer in the context of Article 3.3 activities and the latter in the context of Article 3.4. This reflects the usage in
Decisions 15/CMP.1 and 16/CMP.1, but the methodological treatment of land identification in Chapter 4 of the
GPG-LULUCF was the same in both cases, so uniting the concepts simplifies the text and avoids the impressionthat Parties need to treat the cases differently, which is not required and would increase costs.
This document uses the terms “mandatory” and “elective”. Mandatory refers to activities defined under Article
3.3, namely AR, and D, as well as FM and those 3.4 activities that were elected by a country in the previous CP.
Elective refers to those 3.4 activities that can be elected by a country for the second CP, namely CM, GM, RV if
not already elected in the first CP, and WDR.
Parties are encouraged to harmonize UNFCCC and KP estimation in order to increase transparency, accuracy
and consistency. For the second CP, Parties are required to use the same definition of forest that they selected forthe first CP6. It is good practice to apply the same forest definition for both UNFCCC and KP reporting. Under
the KP Parties are requested to apply a forest definition, within the thresholds of the forest parameters defined by
4

Article 7, paragraph 1 of the Kyoto Protocol: Each Party included in Annex I shall incorporate in its annual inventory […]the necessary supplementary information for the purposes of ensuring compliance with Article 3 […].
Article 7, paragraph 2 of the Kyoto Protocol: Each Party included in Annex I shall incorporate in its national
communication, submitted under Article 12 of the Convention, the supplementary information necessary to demonstratecompliance with its commitments under this Protocol.

the KP, that is consistent with that used to submit historical information to the Food and Agriculture
Organization of the United Nations (FAO) and other international bodies, including the UNFCCC. Where thedefinitions differ for KP reporting and other reporting, Parties are required by Decision 2/CMP.8 to provide an
explanation of why and how such values were chosen, in accordance with Decisions 16/CMP.1 and 2/CMP.7.
Estimation and reporting of GHG emissions and removals from activities defined under Article 3.3 and Article
3.4 are in accordance with Decision 2/CMP.8 on “Implications of the implementation of decisions 2/CMP.7 to

Inventories: Wetlands (Wetlands Supplement)7, any future elaboration of those guidelines, or parts of them, in

OVERVIEW OF STEPS TO ESTIMATING ANDREPORTING SUPPLEMENTARYINFORMATION FOR ACTIVITIES UNDERARTICLES 3.3 AND 3.4

This section gives an overview of the steps required to measure, estimate and report anthropogenic emissions bysources and removals by sinks, including non-CO2 GHG emissions associated with LULUCF activities covered
by Articles 3.3 and 3.4 of the KP. This overview is summarized as a flowchart in Figure 1.1. Detailed methods
and good practice guidance for each individual activity are provided in subsequent Chapters and Sections of thisdocument.

STEP 1:
Defi nitions a nd parameter values o f forests, and hierar chi cal orderof elected Article 3.4 activities.

Parties that have elected any eligible activity under Article 3.4 in a previous CP shall account for 8 the activity
during the second CP, and consistently apply the definition of Article 3.4 activities to their national
circumstances as was done in a previous CP. Parties decide and report which, if any, additional activities under
Article 3.4 they elect for the second CP. It is good practice that Parties document, for each elected activity andfor FM, how the definitions will be applied to national circumstances. It is good practice to choose criteria on
how to apply definitions in such a way as to avoid overlap and to be consistent with the guidance provided in thedecision tree in Figure 1.2 in Section 1.3.

Parties that have already selected the parameters of the forest definition in the first CP are required to apply thisdefinition consistently in the second CP. Parties that have not yet done so need to select the parameters that define
forest, i.e., the minimum area (0.05 – 1 ha), the minimum tree crown cover at maturity (10 – 30%), and theminimum tree height at maturity (2 – 5 m). Areas that meet these minimum criteria are considered forest, as arerecently disturbed forests or young forests that are expected to reach these parameter thresholds at maturity. The
numerical values selected for those parameters cannot be changed during or between CPs. Each Party has todemonstrate in its reporting that selected values are consistent with the information that has historically beenreported to the FAO or other international bodies, including the UNFCCC, and if they differ, explain how and why
differing values were chosen.

The IPCC also produced the 2013 Supplement to the 2006 IPCC Guidelines for National Greenhouse Gas Inventories:
Wetlands (Wetlands Supplement) in parallel to this document in October 2013.

According to the Annex to Decision 16/CMP.1, paragraph 1(a), “forest” is a minimum area of land of 0.05 – 1.0 hectareswith tree crown cover at maturity in situ (or equivalent stocking level) of more than 10 – 30 per cent with trees with thepotential to reach a minimum height of 2 – 5 metres at maturity in situ. A forest may consist either of closed forest
formations where trees of various storeys and undergrowth cover a high proportion of the ground, or open forest. Youngnatural stands and all plantations which have yet to reach a crown density of 10 – 30 per cent or tree height of 2 – 5
metres are included under forest, as are areas normally forming part of the forest area which are temporarily unstocked asa result of human intervention such as harvesting or natural causes but which are expected to revert to forest.

1.7Chapter 1: Introduction

In applying Decision 16/CMP.1 definition of forest during the first CP, some countries excluded certain types ofland e.g. fruit orchards, grazed savannas, urban trees, and some types of plantations, even if these lands meet thethresholds for forest.
In cases where countries apply these exclusions, to achieve transparency in reporting it is good practice:

To document the rationale of criteria used to exclude from forest those areas which meet the thresholds forforest (e.g. consistency with national forest inventories, with reporting to FAO), and how these criteria areapplied consistently across the country and CPs;

To report the extent of the area which meets the thresholds for forest, but is not reported as forest and todescribe the consequences of this exclusion for reported emissions and removals; andThat any harvested wood product (HWP) from timber harvested from forests where the emissions andremovals are not accounted under Article 3.3 AR or Article 3.4 FM not be included in HWP carbon stockreporting.

Countries that exclude in this way land that would otherwise meet the definition of forest, where this land is stillreported under an elected Article 3.4 activity, have to report, and account, carbon emissions and removals
associated with carbon stock changes in woody biomass, including emissions associated with the removal of tree
cover below the forest threshold. Where this land is not reported under an elected Article 3.4 activity, neither
emissions nor removals associated with tree growth or loss are accounted. It is good practice to describe theconsequences of this exclusion for reported emissions and removals by providing information about theirmagnitude and net balance.
STEP 1.2:
Define natural forest and planted forest. It is good practice that Parties, according to theirnational circumstances: (a) provide their definition of natural forest and planted forest (which include forest
plantation as defined in the 2006 IPCC Guidelines); (b) define when a conversion from natural forest to planted
forest occurs; and (c) apply these definitions consistently throughout the CPs.
STEP 1.3:
If applicable, consistent with Section 2.3.9 (Disturbances), define, for AR and FM activities,
natural disturbances in terms of type, and calculate for each activity the background level of emissions associatedwith disturbances and a margin, where a margin is needed.
STEP 1.4:
Establish a hierarchy among Article 3.3, FM and elected Article 3.4 activities to provide aframework for consistent attribution.
 Article 3.3 activities and FM are mandatory and take precedence over elected 3.4 activities;
Once land has been reported and accounted under the KP it cannot be excluded from reporting andaccounting and the hierarchy needs to recognise this; andDouble counting needs to be avoided.

In addition to the framework established by the CMP decisions it is good practice to establish a hierarchy among
elected Article 3.4 activities: CM, GM, and/or RV, noting that WDR is by definition the lowest level of thehierarchy. It is also good practice to apply the same hierarchy among elected activities under Article 3.4 acrossCPs.
Thus the overall hierarchy among mandatory and elected activities is established as follows:D activities take precedence in the reporting hierarchy over AR activities. Therefore, land that was reported
under D, on which subsequent regrowth of forests occurs continues to be reported under Article 3.3 (D) and
it is good practice to report it as a subcategory to indicate that this previously deforested land can be acting
as a carbon sink.

AR and D activities take precedence in the reporting hierarchy over FM activities.

AR, D and FM activities take precedence in the reporting hierarchy over any other elected Article 3.4
activity.

Parties establish the reporting hierarchy among elected activities of CM, GM and RV.

Since WDR is limited to lands that are not accounted for under any other activity10 , lands not alreadyreported under any of the above activities in a given year, on which drainage and rewetting of organic soils
take place are reported under WDR, if elected by the Party.

of Annex to Decision 2/CMP.7 contained in document

2013 Revised Supplementary Methods and Good Practice Guidance Arising from the Kyoto Protocol

Chapter 1: Introduction

In addition to these general guidelines, Decision 2/CMP.7 also provides for the following circumstances:Land subject to direct human-induced conversion from forest to non-forest is reported under D (Article 3.3)
unless a Party chooses to use the provision for CEFC and all requirements (paragraph 37 in Annex toDecision 2/CMP.7) are met, in which case it is reported under FM (see Section 2.7.7 for details andrequirements);Land subject to direct human-induced conversion from non-forest to forest is reported under AR (Article 3.3)
unless this land is used to compensate the harvest of forest plantations and conversion to non-forest land
under the provisions for CEFC and all requirements (paragraph 37 in Annex to Decision 2/CMP.7) are met,in which case it is reported under FM as explained in the previous paragraph (see Section 2.7.7 for details
and requirements).

Where elected activities under Article 3.4 overlap, it is good practice to apply consistently the specified
hierarchy to determine under which activity the land is to be reported. For example, if land could fall into both
CM and RV (such as for new orchards), then it is good practice to report over time that land under one and only
one activity according to the established hierarchy.
Agricultural land use may rotate between Cropland and Grassland associated with grazing. Where a Party has
elected both Article 3.4 CM and GM activities 11 , to reduce reporting complexity and to avoid artefacts or
inaccuracies in CM and GM reporting associated with rotation of land between Cropland and Grassland use, aParty may report all land subject to CM and GM under a single activity, normally CM. Although the reporting
could occur under one activity, estimation of emissions and removals has to follow the methodologies
established for CM or GM, consistent with the activity on the area. Where a Party has elected only one activity,
either CM or GM (Article 3.4), it is good practice to report and account the land subject to rotation under theelected activity.

STEP 2:
Article 3.4

Land identificatio n for mandator y and el ect ed activities und er

The second step of the inventory assessment is to determine the areas on which the activities have taken placesince 1990 (and for which emissions and removals will be estimated). This step builds on the approaches
described in Chapter 3, Volume 4 of the 2006 IPCC Guidelines.
STEP 2.1:
Stratify the country into areas of land for which the geographic boundaries will be reported, as
well as the areas of land subject to Article 3.3 and the areas of land subject to Article 3.4 within these geographic
boundaries (see Section 2.2). This step can be omitted if Reporting Method 2 (see Section 2.2.2) is used.
Stratification of the country should occur at the following four levels:

Level 1: stratify the country into areas subject to the six land-use categories, and associated subcategories, as
defined in the 2006 IPCC Guidelines;

Level 2: stratify the land-use categories into areas of land subject to mandatory or elected activities or not
subject to any mandatory or elected activity;

Level 3: stratify the area subject to activities into areas of mineral soils and organic soils;Level 4: where such activities do occur, stratify areas with organic soils into areas subject to drainage orrewetting or neither drained nor rewetted.

STEP

2.2:

Initial conditions: Compile initial land-use and land-cover information for 31 December 1989.

Using the selected definitions of forest determine forest and non-forest areas on 31 December 1989. This can beaccomplished with a map that identifies all areas considered forest, or with statistical data derived from anational land survey as time-series of a national forest inventory. All forest-related land-use change activities
since 1 January 1990 can then be determined with reference to either maps or statistical sets of data (see Section
2.2.2).

1.9Chapter 1: Introduction

STEP 2.3:
Identify lands that are subject to mandatory (STEP 2.3.1) activities (since 1 January 1990) andelected activities (STEP 2.3.2), and estimate the total area of these lands within each geographic boundary.
STEP 2.3.1: Mandatory activities (AR, D and FM)
Identify lands that, since 1 January 1990, are subject to activities that are mandatory for reporting (AR, D andFM), and estimate the total area of these lands within each geographic boundary. Under Reporting Method 2(Section 2.2.2) the estimation of land areas will be carried out individually for all lands affected.
It is good practice to identify the land area subject to FM in each inventory year of the CP. A country could
interpret the definition of forest management in terms of specified forest management practices undertaken since
1990, such as fire suppression, harvesting or thinning (narrow approach). Alternatively, a country could interpretthe definition of forest management in terms of a broad classification of land subject to a system of forest
management practices, without the requirement that a specified forest management practice has occurred on eachland (broad approach) (for details see Section 2.7.1).
Parties are required12 to estimate and report the area of lands that have been subject to AR and D and the area oflands subject to FM within the boundaries mentioned in STEP 2 above (for details see Sections 2.2.2, 2.5 and 2.6).
Furthermore, each Party is required to estimate and report areas of lands that fall into categories defined by decision
2/CMP.7: it is therefore good practice to report, for each year in the CP, the area of lands with natural forests thathave been converted to planted forests and to report the associated emissions under FM. Countries which haveselected to use the provisions of natural disturbance or CEFC need to provide the georeferenced locations of:

Those lands affected by natural disturbances in the CP for which Parties chose to exclude from theaccounting emissions and subsequent removals; andWhere Parties chose to implement and meet the provision of CEFC, those lands of forest plantation whichhave been harvested and converted to non-forest land as well as those lands that have been converted toforest to compensate for harvesting of forest plantation.

STEP 2.3.2:
Elected activities (CM, GM, RV, and/or WDR)
Identify and estimate the area of lands subject to elected activities under Article 3.4 within each geographic
boundary. Under Reporting Method 2 (Section 2.2.2) the estimation of areas of land is carried out individuallyfor all lands subject to elected Article 3.4 activities.
For CM or GM as discussed in more depth in Sections 2.9 – 2.10, each Party identifies the land area subject tothe activity in each inventory year of the CP as well as in 1990 (or the applicable base year), because GHG
emissions and removals in the base year are used in the accounting.
For WDR and RV each Party identifies the land area subject to the activity since 1990. The GHG emissions andremovals in the base year (1990) are used in the accounting.
STEP 2.3.3: Lands subject to Article 6 project activities
Some lands subject to Article 3.3 or Article 3.4 activities can also be subject to projects under Article 6 of the KP.
These have to be reported under Article 3.3 or Article 3.4. In addition, these lands need to be delineated and the
GHG emissions and removals reported separately as part of project reporting (see Section 4.3 of the GPGLULUCF). The relationship between estimation and reporting of activities under Articles 3.3 and 3.4, andprojects under Article 6, is discussed in Section 1.4.

STEP 3.1:
Estimate GHG emissions and removals for each year of the CP, on all areas subject to the
mandatory and elected activities (as identified in steps 2.3.1 and 2.3.2) while ensuring that there are no gaps andno double counting.
The estimation of GHG emissions and removals for an activity begins with the onset of the activity or the
beginning of the CP, whichever comes later.

GENERAL RULES FOR CATEGORISATION OF
LAND AREAS UNDER ARTICLES 3.3 AND 3.4

Chapter 3 (Consistent representation of lands), Volume 4 of the 2006 IPCC Guidelines describes approaches toclassifying and representing land areas associated with six land-use categories. This is the basis for the goodpractice guidance in this KP Supplement for identifying all relevant lands, for KP reporting, and for avoiding
double counting of lands. It is good practice to follow the decision tree in Figure 1.2 for each reporting year of
the CP in order to:Distinguish between AR and D activities under Article 3.3, and FM, CM, GM, RV and WDR activities
under Article 3.4, as well as to remove potential overlaps and gaps between them; and toAssign lands, where activities occurred, to a single activity at any given point in time (i.e., for the base year
and each year of the second CP). This is required because of the possible changes in land use or activities
which can lead to double counting of lands subject simultaneously to mandatory and elected activities.
Guidance on how to deal with shifts in land use over time is exemplified in Box 1.1 at the end of this section.

The decision tree in Figure 1.2 is based on the definitions given in the Annexes to Decisions 16/CMP.1 and
2/CMP.7. It identifies a single activity for a given year X of the CP under which the land should be reported. The
decision tree recognises that a given piece of land could be reported under different activities over time, subject
to certain conditions explained below. The decision tree is to be applied annually during the CP in order toupdate the allocation of lands to activities, thus taking into account shifts in land use that may have occurred.
This may be achieved by annual tracking of land or by interpolation between consecutive assessments of land
use.
There are two main branches in the decision tree in Figure 1.2. If land is covered by trees in the reporting year,
then the questions in the “centre” branch should be answered to determine whether the land was subject toactivities under Article 3.3, FM, or any elected Article 3.4 activities. If land is not covered by trees in thereporting year, then the questions in the “left” branch should be answered to determine whether the land was
subject to deforestation at any time since 1st January 1990, or subject to any other activities which could beclassified as Article 3.3 and 3.4 activities. This is required to fulfil the reporting needs specified in the Annex toDecision 2/CMP.7, and to demonstrate that there is no double counting, which could occur if full enumeration
was not applied. More detailed decision trees and examples to determine whether or not land is subject tospecific activities under Articles 3.3 and 3.4 are presented in Sections 2.5 through 2.12.
For land that is subject to an Article 3.4 activity, it is necessary to know whether it was subject to any othermandatory or elected activity in the previous year. If the land was subject to a mandatory activity it should be
kept under that activity, otherwise it is good practice to assign it to the elected activity that is higher in thehierarchical order of elected Article 3.4 activities, using the hierarchy established in Step 1.4 above. Similarly, if
land is subject to more than one Article 3.4 activity, it is good practice to assign it to the elected activity that ishigher in the hierarchical order.

1.12

2013 Revised Supplementary Methods and Good Practice Guidance Arising from the Kyoto Protocol

Chapter 1: Introduction

In addition, note that:

The decision tree in Figure 1.2 is not sufficient to assign all lands to specific activities. For the reporting ofthese lands, it is good practice to follow the methodological guidance provided under Section 2.2 on“Generic Methodologies for Area Identification, Stratification and Reporting”, and in the activity-specificsections on land identification in Sections 2.5-2.12.

For the second CP, Article 3.3 applies to land that is subject to an AR or D activity at any time between 1
January 1990 and 31 December of the last year of each CP.



For reporting during the second CP, Article 3.4 applies to land that is subject to FM and any activity of CM,
GM, RV, or WDR elected during the CP or in any year of the previous CP13. Any Article 3.4 activities
elected in the first CP must be reported during the second CP. Article 3.4 also applies to land subject to RV,
and when a narrow approach to their definitions is applied, to FM and WDR since 1 January 1990.

Once land is accounted for and therefore reported under an Article 3.3, FM or elected Article 3.4 activity, allanthropogenic GHG emissions from sources and removals by sinks on this land must be reported from thattime forward through the second CP14, except where the country chooses not to report a pool that has beenshown not to be a source as explained in Section 2.3.1. Therefore, in principle the total land area included in
the reporting of Article 3.3 and 3.4 activities can never decrease. For CM and GM, the guidance provided in
the GPG-LULUCF (Box 4.2.8) acknowledges that some of the area of the activity in the ‘base year only’
may no longer be reported under that activity in the reporting year. Where this area is not transferred toanother reported activity the associated emissions and removals will be accounted as zero in that year. In
order to achieve transparency in reporting, it is good practice to describe the consequences of this exclusion
on reported emissions and removals.



In order to avoid the reporting of land under more than one activity in any year during the CP, it is goodpractice to apply the following :





-

Land subject to activities under Article 3.3 which would otherwise be subject to FM or an elected
activity under Article 3.415 are to be identified as lands that are both subject to Article 3.3 and 3.4
activities by using secondary classifications (these are not shown in the decision tree in Figure 1.2). The
decision tree implies that AR, D and FM have precedence over the other activities for land classification
and reporting purposes for the second CP; and-For lands that are subject to more than one activity under Article 3.4, it is good practice to apply thenational criteria that establish the hierarchy among elected Article 3.4 activities (see STEP 1.4 in
Section 1.2 above).

Land subject to loss or gain of forest cover can move between categories in the following cases:-

Land classified as forests at any time since 31 December 1989, including AR land and subsequently
deforested is reclassified as D land (see Sections 2.5 and 2.6 for details).

-

Land under an elected Article 3.4 activity that becomes subject to an Article 3.3 activity needs
subsequently to be reported under the latter. For the second CP, land on which forest plantations were
established before 1 January 1990 and are subject to forest management (including those lands whichwere re-established as forest plantation after 1 January 1960 and before 1 January 1990) that is clearedof forest can be reported as FM, if the conditions of CEFC are met (see Section 2.7.7)16.

The following transitions are not possible. Note that these restrictions apply to reporting under the KP (butdo of course not affect the actual management that a country applies to its lands):-

Land cannot be transferred from FM (mandatory under Article 3.4) to an elected Article 3.4 activity;-

Land cannot be transferred from an elected to an unelected Article 3.4 activity;-

Land cannot leave the Article 3.3 reporting; and13

Conversely, for base year reporting, Article 3.4 applies to land that was subject to an elected CM, GM, RV, or WDR
activity in the base year.

Chapter 1: Introduction-

D land cannot become AR land. It is good practice to report carbon stock changes associated with forest
regrowth on previously deforested land as a subcategory of D to indicate why D land may act as acarbon sink (See Section 2.6). In such cases it is good practice to estimate emissions and removals using
the methodology for lands converted to forest land as described in the 2006 IPCC Guidelines.

It is good practice to define the boundaries between FM and CM or GM, where these are applied on thesame area, using the national forest definition applied consistently with past reporting practice as describedat Step 1.1 above.

In summary, this means that the area under Article 3.3 (AR and D) will grow from 0 hectares on 31 December
1989 up to a certain value at the end of the second CP. At any given point in time, it is good practice that the AR
and D categories should contain all areas of land that have been afforested, reforested or deforested since 1
January 1990. The land area under Article 3.3 D will increase in size or stay constant during the second CP. The
land area in the AR activity will typically increase, but could decrease if AR lands are subject to deforestation
activities.
The amount of lands under FM or elected Article 3.4 activities can fluctuate because of various land-use changes.
It is unlikely that those areas will stay constant over time for the purpose of reporting because, for example:

A deforestation event can transfer land from FM to D under Article 3.3;



An afforestation or reforestation event can transfer land from any non-forest Article 3.4 activity to the
Article 3.3 AR activity;

GM can become CM and vice versa, and it is reported under the elected Article 3.4 activity most recently
applied to the land;

RV can become CM or GM or vice versa, and it is reported under the elected Article 3.4 activity mostrecently applied to the land;FM areas can increase, for example, as countries expand the road infrastructure to areas previously
inaccessible and unmanaged and initiate harvest and other FM activities17; andDrained organic soils can become FM, CM, GM, RV or WDR, consistent with national definitions andcriteria for classification and activities on these soils.

Box 1.1 provides several examples that summarise the considerations that apply for lands subject to activities
under Articles 3.3 and 3.4 of the KP. For more detailed explanations of the rationale behind the examples in Box
1.1, the reader is referred to the more detailed explanations in the remaining sections of this supplement.

17

Note, in this example, the construction of the road infrastructure may have also increased D depending on national
definitions of minimum area and width for forest.

EXAMPLES FOR THE ASSIGNMENT OF LANDS TO ARTICLE 3.3 AND 3.4 ACTIVITIES OVER TIME

The following examples are intended to show, conceptually and in accordance with the decision
tree in Figure 1.2, how different land-use conversions would be categorised in different inventory
years of the KP. This does not necessarily imply that the land-use transition can be directly
measured on an annual basis. For croplands and grazing lands only carbon stock changes are
discussed in the examples below, since non-CO2 GHG emissions for such lands are in most cases
reported under the Agriculture sector.
Example 1: Land under FM is deforested in 1995 and turned into cropland.
Carbon stock changes on this land are reported under D from 2008 onwards through the second
CP. CO2 emissions from liming and urea application as well as non-CO2 GHG emissions on thisland are reported under the Agriculture sector.
Carbon stock changes on this land will not be reported under CM, even if CM was elected, because
D takes precedence over CM. The decision tree in Figure 1.2 therefore assigns this land to D.
Should trees be re-established on this land after the end of the first CP, for example in 2014, theland does not transition from one Article 3.3 activity to another (from D to AR). The land
continues to be reported under D. Estimates of carbon stock changes and non-CO2 GHG emissions
will be based on the methodologies for land converted to forest land.
Example 2: Land under FM is deforested on 1 January 2015 and turned into cropland.
Carbon stock changes on this land during the second CP are reported under D starting in 2015. The
methodology for croplands that were previously forest should be used to estimate carbon stockchanges. Non-CO2 GHG emissions associated with cropland use and CO2 emissions from liming
and urea application are estimated using methods described in Volume 4 of the 2006 IPCC
Guidelines, and are to be reported in the national inventory within the Agriculture sector.
Carbon stock changes and non-CO2 GHG emissions on this land will not be reported under CM,
even if CM has been elected, because D takes precedence over CM. The decision tree in Figure 1.2
therefore assigns this land to D.
Example 3 to 12
The following examples illustrate how Article 3.3 or 3.4 activities are to be reported during thesecond CP. For each example a brief scenario is presented and the correct land management
activity for reporting, identified as the “Reporting solution”, is provided in a table with additional
explanation in the comment row.
More than one solution may be acceptable after the conversion or management change dependingon the nationally-defined hierarchy of elected 3.4 activities established at the start of the CP.
Abbreviations used in the tables:
D- Deforestation; AR- Afforestation and Reforestation; FM- Forest Management; CM- CroplandManagement; GM- Grazing Land Management; RV- Revegetation; WDR- Wetland Drainage andRewetting
M- Mandatory reporting obligation; E- Elected activity; N/E- Not Elected; N/A- Not Applicable inthis reporting period.
CP1- First CP 2008-2012 inclusive
CP2- Second CP 2013-2020 inclusive
A blank cell in the tables means the activity is not applicable.

Comments

Two reporting scenarios are possible. The converted land can be classified as GM or
RV according to their level in the hierarchy established by the country. The reporting isbased on the definitions for classifying lands under the activities. When communicating
the decision to elect the KP activity for CP2, the country is required to provide thedefinitions of activities which will be classified under each KP activity and thehierarchy of elected activities which it will apply. Accounting will not be affected bywhich option is chosen.

RELATIONSHIP BETWEEN ANNEX I PARTIES’NATIONAL INVENTORIES AND ARTICLE 6
LULUCF PROJECTSEmissions or removals resulting from projects under Article 6 will be part of the host country’s annual inventory
under the KP reporting18. The methods for measuring, estimating, and reporting GHG emissions and removals
resulting from LULUCF project activities are addressed in Section 4.3 of the GPG-LULUCF (LULUCF
Projects).
When estimating the GHG emissions and removals of Article 3.3 and 3.4 activities, it is possible to use theinformation that is reported for, or is meeting the standards of, Article 6 LULUCF projects on these lands (butnot vice versa). Two options exist for Article 3.3 and Article 3.4 estimation, both of which are considered goodpractice:
Option 1: Carry out Article 3.3 and Article 3.4 assessment without consideration of information reported for
Article 6 projects (which are reported separately as outlined in Section 4.3 of the GPG-LULUCF). This assumes
that a properly designed national system will also automatically include the effects of Article 6 projects. Thisapproach is consistent with the approaches taken in the other emission sectors. For example, an Article 6 projectthat increases removals by afforesting new areas is not individually considered in the national emissions
inventory, but will implicitly be included due to the project’s impacts in the national statistics for AR.
Option 2: Consider all changes of carbon stocks as well as GHG emissions and removals at the project level as a
primary data source for Article 3.3 and/or Article 3.4 estimation and reporting, for example by considering
projects as a separate stratum. Any Article 3.3 and 3.4 activities that are not projects need to be monitored
separately. In this case, the design of the monitoring must ensure that projects are explicitly excluded from theremaining lands under Articles 3.3 and 3.4, to avoid double counting.
One important difference between project and national (Articles 3.3 and 3.4) accounting is that projects have abaseline scenario (i.e., only additional carbon stock changes and non-CO2 GHG emissions due to the project are
accounted) and a project boundary, while AR, D, CM, GM, RV and WDR do not have a baseline scenario. CM,
GM, RV and WDR use the emissions and removals in the base year in the accounting. After the first CP, FM
does have a FM reference level. Therefore, when using project-level information for reporting under different
activities of Articles 3.3 and 3.4, countries must take into account the projects’ total contribution to reported
overall carbon stock changes and non-CO2 GHG emissions and not just the change relative to the projects’baseline scenario.

Chapter 2: Methods for estimation, measurement, monitoring and reporting

2 METHODS FOR ESTIMATION,
MEASUREMENT, MONITORING ANDREPORTING OF LULUCF ACTIVITIES UNDERARTICLES 3.3 AND 3.4
Chapter 2 of the 2013 Revised Supplementary Methods and Good Practice Guidance Arising from the Kyoto
Protocol (KP Supplement) provides a description of generic methodological issues concerning all possible landuse, land-use change and forestry (LULUCF) activities under Kyoto Protocol (KP) Articles 3.3 and 3.4. Section
2.1 deals with the relationship between land-use categories in reporting under the United Nations Framework
Convention on Climate Change (UNFCCC) and the KP, Section 2.2 deals with land areas, Section 2.3 withestimating carbon stock changes and non-CO2 GHG emissions, including those from natural disturbances(Section 2.3.9), and Section 2.4 deals with other generic methodological issues. These are followed by specificmethodologies related to Afforestation (A) and Reforestation (R) (treated together), Deforestation (D), Forest
Management (FM), Harvested Wood Products (HWP), Cropland Management (CM), Grazing Land
Management (GM), Revegetation (RV), and Wetland Drainage and Rewetting (WDR) (Sections 2.5 – 2.12).
Readers should refer to both the generic and the specific methodologies for any one of these activities.

2.1

RELATIONSHIP BETWEEN UNFCCC LANDUSE CATEGORIES AND KYOTO PROTOCOL(ARTICLES 3.3 AND 3.4) ACTIVITIESThis section provides an overview of the relation between the activities under Articles 3.3 and 3.4 and the landuse categories introduced in Chapter 2, Volume 4 of the 2006 IPCC Guidelines for National Greenhouse Gas
Inventories (2006 IPCC Guidelines).
Land-use categories are classified in Volume 4 of the 2006 IPCC Guidelines into:(i)

Forest Land (Chapter 4)(ii)

Cropland (Chapter 5)(iii)

Grassland (Chapter 6)(iv)

Wetlands (Chapter 7)(v)

Settlements (Chapter 8)(vi)

Other Land (Chapter 9)

The relationships between the basic land-use categories (i) to (vi), described in Chapter 3, Volume 4 of the 2006
IPCC Guidelines and the activities of the KP (Articles 3.3 and 3.4), are summarised in Table 2.1.1. Land subject
to KP activities should be identified as a subcategory of one of these six main categories. There are no reportingor accounting requirements for emissions from unmanaged land categories under the KP or the UNFCCC.
However, for completeness of reporting and consistency of time series, it is good practice to report the total areaof the country including those areas not subject to any activity as well as the area of lands classified as
unmanaged lands under the UNFCCC.
Using categories (i) to (vi) as a basis for estimating the effects of Articles 3.3 and 3.4 activities helps meet goodpractice requirements and will be consistent with the national land categorization used for preparing LULUCF
GHG inventories under the Convention. For example: Forest Land could be partitioned into: a) Forest Land
under Article 3.3; b) Forest Land under Article 3.4, c) Other managed Forest Land (if the definition of “managed
forests” differs from the definition of “lands subject to forest management”); and d) Unmanaged Forest Land.
More information on the relationship between “managed forests” and “forest management” can be found in
Section 2.7, Figure 2.7.1.
Many of the methods described in subsequent sections of this chapter build on methodologies that appear in
Chapter 1 and Section 2.1 to 2.4 of this supplement or in Volume 4 of the 2006 IPCC Guidelines. It is
recommended also to refer to relevant sections of the 2013 Supplement to the 2006 IPCC Guidelines for2013 Revised Supplementary Methods and Good Practice Guidance Arising from the Kyoto Protocol

For KP reporting, spatial stratification beyond thatprovided in the reporting tables in Volume 1 of the 2006 IPCC Guidelines is required, and for the second
Commitment Period (CP), additional reporting categories have been introduced. Section 2.4.4 introduces the
additional reporting requirements and Annex 2A.1 to this document provides draft reporting tables.

Chapter 2: Methods for estimation, measurement, monitoring and reporting

Figure 2.1.1 shows that under UNFCCC LULUCF reporting assigns a land-use category to all land within the
country, while Figure 2.1.2 shows that KP Article 3.3 and 3.4 activities cover a sub-set of the total land area. KP
reporting is complicated by two additional issues:(i)

KP reporting is backward looking, because the history of land use may be important in thedetermination of the activity under which a given land area should be reported; and(ii)

Parties have some flexibility in the definitions of which land-use category is to be included within agiven Article 3.4 activity. See section 1.2.

In Figure 2.1.2, the dashed lines delineate areas subject to FM, and two of the elective activities under Article 3.4,
CM and GM. RV can occur on various land-use categories. By definition, WDR can only occur on lands that are
not already subject to one of the other Article 3.4 or Article 3.3 activities. The area subject to FM can bedifferent, where this occurs usually smaller, than the area of managed forest under UNFCCC reporting because (i)countries could use different thresholds for defining forests for the KP and UNFCCC reporting, (ii) Article 3.4
requires that the management activity took place since 1990, and (iii) land subject to AR after 1990 transitions toForest Land after 20 years under UNFCCC but remains in AR under the KP. Parties are encouraged to adopt
definitions of land use and Article 3.4 activities which are consistent with each other. It is acknowledged that thismay not be possible in all circumstances. For further discussion of this possible definitional difference see Figure
2.7.1 and accompanying text in Section 2.7.2 (Choice of Methods for identifying lands subject to FM).
Emissions and removals on unmanaged forests that remain unmanaged are included in neither UNFCCC nor KP
reporting. The area of unmanaged land is reported under UNFCCC, and should, for example, a human-induced
deforestation event occur in unmanaged forests, the associated emissions would be reported as D event under
Article 3.3, or in the case of drainage of a natural wetland to cropland, the emissions could be reported under CM
or WDR depending on the activities elected by the country. Lands for which emissions from natural disturbances
are not reported (see Section 2.3.9 for additional requirements) need to be identified separately for both FM andAR lands (“ND” in Figure 2.1.2). Lands that are used to establish a CEFC include both the land area that was
harvested and converted to non-forest land, CEF-hc and the previously non-forest land on which the equivalentplantation was newly established, CEF-ne and both of these are reported in FM, (see Section 2.7.7 for additional
requirements).
Although, for KP reporting lands subject to CM can be similar to Cropland/arable/tillage lands in UNFCCC
reporting, flexibility exists especially with regard to woody crops. In cases where there is conversion of forest
land to cropland, these lands are reported under Article 3.3 D. Where GM is elected and CM is not, land subject
to conversion from GM to Cropland during the CP continues to be reported (though the emissions and removals
on that land could be accounted as zero if the land was GM in the base year, see Section 1.3) under GM because
land cannot transition from an elected to an unelected Article 3.4 activity. The same argument is valid in thesituation where there is a transition from CM to GM and CM is elected while GM is not.
GHG emissions and removals on unmanaged grasslands are excluded from both the UNFCCC and the KP
reporting, however it is good practice to include the area of unmanaged lands in the KP reporting together withall other lands not subject to any activity under the UNFCCC.
Lands subject to AR are always managed forests but carbon stock changes and non-CO2 GHG emissions are to
be reported under Article 3.3 (AR) only.
Deforested lands are managed (thus, for instance, there is no “D” box in the unmanaged grasslands).

GENERIC METHODOLOGIES FOR AREA
IDENTIFICATION, STRATIFICATION ANDREPORTING

2.2.1

Reporting requirements

Decisions 2/CMP.7 and 2/CMP.8 state that those areas of land subject to Article 3.3 and 3.4 activities must be
identifiable3, adequately reported4 and tracked over time.5 Section 2.2.2 discusses two land reporting methods
that can be applied to all Article 3.3 and 3.4 activities. Section 2.2.3 introduces the additional reporting
requirements arising from accounting provisions for the second CP. Section 2.2.4 discusses how the tworeporting methods can draw on the three Approaches presented in Chapter 3, Volume 4 of the 2006 IPCC
Guidelines, Section 2.2.5 provides a decision tree for selecting one of the two reporting methods, and Section
2.2.6 includes a more detailed discussion of how lands subject to Articles 3.3 and 3.4 can be identified, so thatthe requirements of either Reporting Method can be satisfied.

2.2.2

Reporting Methods for lands subject to Article 3.3
and Article 3.4 activities

The reporting requirements set out in Decision 2/CMP.8 seek to avoid double counting of land areas and ensurecompleteness in land identification and consistency in reporting. The general information to be reported on
activities under Articles 3.3 and 3.4 shall 6 include the geographical boundaries of areas encompassing land
subject to AR, D, FM and lands subject to elected CM, GM, RV and WDR activities. To achieve this, and basedon national circumstances such as the characteristics of existing forest inventory systems and the size of thecountry, a Party may choose one of two methods (Figure 2.2.1):
Reporting Method 1 uses a spatially-referenced approach that delineates the geographic boundaries that containmultiple land units subject to Article 3.3 or 3.4 activities. The geographic boundaries can be defined using
georeferenced legal, administrative, or ecosystem boundaries. Information about activities within these areas isderived from (grid-based or other) sampling techniques using remote sensing or ground-based data or fromadministrative statistics, although the location of each land unit within these geographic areas may not be known.
See Section 2.2.3 for additional georeferenced reporting requirements arising from Decision 2/CMP.7 for thosecountries that choose additional accounting provisions related to ND and CEFC.
Reporting Method 2 is based on the spatially-explicit and complete geographical identification of all land units
subject to Article 3.3 and Article 3.4 activities.
3

Paragraph 25 of Annex to Decision 2/CMP.7: National inventory systems established under Article 5, paragraph 1, shallensure that areas of land subject to land use, land-use change and forestry activities under Article 3, paragraphs 3 and 4,
are identifiable, and information on these areas shall be provided by each Party included in Annex I in their national
inventories in accordance with Article 7. Such information will be reviewed in accordance with Article 8.

4

Paragraph 2 of Annex II to Decision 2/CMP.8:
General information to be reported for activities under Article 3, paragraph 3, forest management under Article 3,
paragraph 4, and any elected activities under Article 3, paragraph 4, shall include: […](b) The geographical location of the boundaries of the areas that encompass:(i) Units of land subject to activities under Article 3, paragraph 3, of the Kyoto Protocol;(ii) Units of land subject to activities under Article 3, paragraph 3, of the Kyoto Protocol which would otherwise be
included in land subject to forest management or elected activities under Article 3, paragraph 4, of the Kyoto
Protocol under the provisions of decision 2/CMP.7, annex, paragraph 9;(iii) Land subject to forest management under Article 3, paragraph 4, in the second commitment period and to any

Chapter 2: Methods for estimation, measurement, monitoring and reporting

For Reporting Method 1, depending on the size of the country and the ecological and climate variability within
the country, it is good practice to select the number of geographic areas for which the geographic boundaries ofland are defined with the goals to reduce heterogeneity and to increase accuracy and reporting transparency.
Thus, to maintain transparency and reduce uncertainty, unless the country is relatively small, it is good practice
to define the boundaries of more than one geographic area and for relatively large countries it is good practice tolimit the number of geographic areas. The choice of the number of reporting areas affects uncertainty estimates.
To implement Reporting Method 1, it is good practice to define and report the geographic boundaries withcomplete coverage and without gaps or overlaps. Criteria for delineating reporting regions within the country
could include statistical considerations for the sampling intensity or sampling approaches, considerations of thetype and amount of KP activities, as well as ecological or administrative considerations. Within each resulting
geographic boundary lands subject to Article 3.3, FM or other elected Article 3.4 activities will then bequantified using the approaches described in Chapter 3 (Section 3.3 Representing land-use areas), Volume 4 ofthe 2006 IPCC Guidelines, in accordance with the guidance in Section 2.2.3, as well as the methods in Sections
2.2.6 (generic methods) and 2.5 to 2.12 (activity-specific methods) of this supplement.
To implement Reporting Method 2, a country should identify and report the spatial location of all lands based on
a complete mapping of all areas within its national boundary. This is described in Chapter 3, Volume 4 of the2006 IPCC Guidelines as the wall-to-wall mapping version of Approach 3 (see also Section 2.2.4.3). This
Reporting Method uniquely identifies lands and enables activities to be reported without the risk of double
counting of area. To put this Reporting Method fully into practice requires large-scale data collection andanalysis, and the preparation of statistics, which summarise the detailed, polygon or pixel-level information, toensure that reporting is transparent yet concise. Digital maps, which in practice will not be included in the
National Inventory Reports (NIR), can be made available to Expert Review Teams who can then verify
completeness of time series and of spatial coverage.
Examples of national implementations of Reporting Methods 1 and 2 are Canada and Australia, respectively. In
Canada the land area is stratified into 18 reporting zones based on the Terrestrial Ecozone classification system.
15 of these zones contain some 230 million hectares of Managed Forest for which emissions and removals are
estimated (Stinson et al., 2011). The underlying analyses of C stocks are based on forest inventory and activity
data compiled for over 500 forest management units, but within each of these geographic boundaries the exact
location of each forest polygon is not included in the analyses. Australia’s National Carbon Accounting System
uses a wall-to-wall, spatially-explicit approach to estimating carbon stock changes and non-CO2 emissions. Time
series of Landsat images are used to determine land cover and land-use changes and to inform estimates ofcarbon stocks and stock changes (Richards and Brack, 2004; Waterworth and Richards, 2008). Other countryspecific examples can be found in national inventory reports from the UNFCCC website7.

Chapter 2: Methods for estimation, measurement, monitoring and reporting

With either Reporting Method, once land is reported as being subject to activities specified under the KP, it isgood practice that the land be included in the reporting and accounting from the time it entered the system to theend of the second CP. Therefore, if a Party chooses Reporting Method 1 and sampling, it is good practice torecord the information needed to identify the sample locations and the lands identified in the samples, and to use
the same sample locations for any future monitoring. This ensures that land-use changes identified by sample
plots (Reporting Method 1) or in the entire country (Reporting Method 2) can be tracked and monitored from1990 to the end of the CP. However, estimates of the rates of land-use change can also be obtained using
combinations of permanent sample plots, temporary sample plots and time-series of remotely sensed land-coverchange products.
It is good practice to report, using printed or digital maps, as described in Section 2.4.4.1(Reporting), thegeographic boundaries resulting from the stratification of the country.

2.2.3

Reporting Methods for lands subject to additional
accounting provisions for CP2

This Section is only applicable to countries that choose the special accounting provisions of Decision 2/CMP.7
to make use of the natural disturbances (ND) or Carbon Equivalent Forest Conversion (CEFC) provisions.
Decision 2/CMP.7 introduced additional reporting requirements for (1) the georeferenced locations of forest
areas subject to ND for which emissions and subsequent removals are excluded from the accounting8 and (2) thegeoreferenced locations of forest plantations converted to other land uses for which a carbon-equivalent forest
was established on non-forest land and the georeferenced locations of these carbon-equivalent forests9.
Georeferenced locations of areas affected by ND are required to ensure that subsequent removals from theseareas are excluded from the accounting and to track whether or not these areas have been converted to non-forest
land uses (deforestation) in the second CP after the natural disturbance. If land-use change does occur then theland is reported as D and emissions from the natural disturbance previously excluded are reported and accounted
under D.
Decision 2/CMP.7 also states that countries need to demonstrate that emissions associated with salvage logging,i.e. the harvest of dead or dying trees affected by a natural disturbance (see Box 2.3.5 in Section 2.3.9.3 for thedefinition of salvage logging) of these areas were not excluded from the accounting. It is good practice toestimate, report and account emissions from all salvage logging, which includes emissions associated withsalvage logging on lands affected by ND for which emissions were excluded from the accounting. See Section
2.3.9 for additional requirements associated with the ND provision.
Decision 2/CMP.7 requires that the georeferenced locations are reported for cases where certain plantations are
harvested and converted to non-forest land and subsequently non-forest land in another location is planted toestablish a carbon equivalent forest. The georeferenced locations of both the converted plantation and the newly
established plantation are to be reported. The associated emissions and removals are reported under FM (Article
3.4). See Section 2.7.7 for additional requirements associated with the establishment of carbon equivalent forests.
These new reporting requirements imply that for countries that make use of the additional accounting provisions(exclusion of ND emissions and CEFC) Reporting Method 1 can only meet the reporting requirements if
additional, georeferenced information about specific land areas within the geographic boundaries is provided.
Two methodological approaches are available: either, mapping and ongoing monitoring of lands subject to the
ND provisions to determine whether subsequent deforestation has occurred; or all lands that are subject todeforestation events are assessed to determine whether these lands are also subject to the ND provisions.

Methods in Section 2.2.2

Chapter 3, Volume 4 of the 2006 IPCC Guidelines (Consistent representation of lands) describes three
Approaches for representing land area. The detailed reporting requirements of Articles 3.3 and 3.4 of the KP as
elaborated in Chapter 3 are met by the two Reporting Methods previously described in this chapter. This section,

Chapter 2: Methods for estimation, measurement, monitoring and reporting

summarised in Table 2.2.1, discusses which of the three Approaches are suitable for identifying lands subject to
Article 3.3, FM or elected Article 3.4 activities.
The following three Approaches are explained in more detail in Chapter 3, Volume 4 of the 2006 IPCC
Guidelines. Approach 1 identifies the total change in area for each individual land-use category within a country,
but does not provide information on the nature and area of conversions between land uses. Approach 2
introduces tracking of land-use conversions between categories (but is not spatially explicit), therefore does notallow to track conversions over time for individual lands. Approach 3 is characterized by spatially-explicit
observations of land-use categories and land-use conversions and thus enables tracking of conversions over timeof individual lands.
Table 2.2.1 describes the three Approaches which will be described in the subsequent sections, and relations
between Approaches and Reporting Methods.

2.2.4.1

APPROACH 1: TOTAL LAND-USE AREA, NO DATAON CONVERSIONS BETWEEN LAND USES

Approach 1 described in Chapter 3, Volume 4 of the 2006 IPCC Guidelines provides information that is not
spatially explicit and it only reports the net changes in the areas of different land-use categories. Hence, thisapproach does not meet the land identification requirements of Decisions 16/CMP.1 and 2/CMP.7. National
inventory databases are often compiled from detailed inventories that can be based, for example, on sampling
approaches that involve a grid or sample plot system. In countries where this is the case, it may be possible to reanalyse the detailed inventory information with reference to the geographical boundaries, which have resulted
from the stratification of the country, to meet the reporting requirements of the KP. Inventories based on
georeferenced permanent sample plots are suitable to detect land–use conversions. This means that Approach 1
can only be applied to Reporting Method 1 if additional spatial data at the required spatial resolution areavailable as a result of re-analysing the inventory information or from other sources, and if additional
information is available to quantify the gross land-use transitions (rather than the net changes in land-use
categories).

2.2.4.2

APPROACH 2: TOTAL LAND-USE AREA, INCLUDINGCHANGES BETWEEN CATEGORIESApproach 2 focuses on land-use transitions and provides an assessment of both the net losses or gains in the areaof specific land-use categories and what these conversions represent (i.e. changes both from and to a category).
The final result of this Approach can be presented as land-use conversion matrix that is not spatially explicit.
Thus, Approach 2 differs from Approach 1 in that it includes information on conversions between categories, but
is still only tracking those changes without spatially-explicit location data, which means that the Approach does
not allow tracking of conversions between land-use categories. Hence, additional information is necessary tomeet the reporting requirements of Decisions 16/CMP.1 and 2/CMP.7. This Approach can therefore only be used
to identify lands subject to activities under Articles 3.3 and 3.4 if additional data are available that allow tracking

2.18

2013 Revised Supplementary Methods and Good Practice Guidance Arising from the Kyoto Protocol

Chapter 2: Methods for estimation, measurement, monitoring and reporting

lands, and land-use changes, over time possibly on a statistical basis. As with Approach 1, it may be possible toapply Approach 2 to Reporting Method 1 if additional spatial data at the required spatial resolution become
available from re-compiling the inventory information or other sources.

2.2.4.3

APPROACH 3: SPATIALLY-EXPLICIT LAND-USE
CONVERSION DATA

Approach 3 is characterized by spatially-explicit observations of land-use categories and land-use conversions,
often tracking patterns at specific point locations and/or using gridded map products, such as derived fromremote sensing imagery. The data may be obtained by various sampling, wall-to-wall mapping techniques, or
combination of the two methods. This Approach is applicable to Reporting Methods 1 and 2 (Section 2.2.2), as
long as the spatial resolution is fine enough to represent the minimum forest area as defined by the Party underDecision 2/CMP.7 and its precursors.
Note that even the most data-intensive Approach 3 can only be sufficient without supplemental information if
the spatial resolution at which land-use changes are tracked is consistent with the size parameter selected by acountry to define forest, i.e. polygon sizes of 0.05 to 1 ha or pixels of 22.4 to 100 m (see STEP 1.1 in Section
1.2). Mapping land cover and land-use using, for example, 1 km2 (100 ha) pixel resolution may not meet the KP
requirements because land-use change at finer resolution may not be detected. A well designed sample-based
approach (Magnussen et al., 2005) at the appropriate spatial resolution may therefore yield more accurate
estimates than a wall-to-wall map at 1 km2 resolution which may miss many small land-use change events.
Sample-based approaches can provide the required supplemental information.

2.2.5

Choice of Reporting Method

It is good practice to choose an appropriate Reporting Method using the decision tree in Figure 2.2.2. National
circumstances may enable a country to use a combination of both Reporting Methods. In such a case, it is goodpractice to first stratify the entire country and then to quantify and report the area of land using Reporting
Method 1. Within those geographical boundaries where data for complete spatial identification of lands areavailable, Reporting Method 2 can then be applied.
As outlined in Section 2.2.3, additional georeferenced information is required for areas subject to ND and CEFC
provisions. For either Reporting Method, this additional information could be reported using time series of maps
or tables containing the georeferenced information about the location of these lands. See also the Reporting
Tables presented in Annex 2A.1 to this document.

When using Reporting Method 1 it is usually good practice to use the same geographical boundaries for all
activities. This will greatly facilitate the identification, quantification, and reporting of land-use changes.
National circumstances may provide justification for different choices of geographic boundaries for different
activities, e.g. different geographic boundaries may be chosen to reduce the variance of estimates for one activity
within a given boundary. When a Party uses more than one set of geographic boundaries (i.e. more than one
stratification system is used), lands subject to Article 3.3 or 3.4 activities that transition from one category toanother must be appropriately assigned to the correct geographical boundary. This might require proportional
allocation of the land to each stratification system in use.

2.2.6

How to identify lands in general

2.2.6.1

SPATIAL CONFIGURATION OF FORESTS AND
AFFORESTATION, REFORESTATION OR
DEFORESTATION EVENTSEach Annex I Party to the KP has chosen country-specific parameters within the definition of forest for their KP
reporting. This required selecting values for the following three parameters: the size of the minimum area of landthat can constitute a forest, ranging between 0.05 and 1 ha, and parameters for minimum crown cover (orequivalent stocking level) between 10 – 30% and tree height at maturity (2 – 5 m). The parameter for theminimum area of land that constitutes a forest effectively also specifies the minimum area on which land-use
change events occur (i.e. AR, D, or CEFC) and for those areas where natural forests are converted to planted
forest. Thus a country that selects, for example 0.5 ha as the minimum area of forest land, must also identify allland-use change events that occur on lands that are 0.5 ha or larger. The identification of lands on which land-use

2.20

2013 Revised Supplementary Methods and Good Practice Guidance Arising from the Kyoto Protocol

Chapter 2: Methods for estimation, measurement, monitoring and reportingchanges occur, such as deforestation, requires the detection of a direct human-induced reduction in tree crowncover from above to below the country-specific threshold of forest, accompanied by a change in land-use.
The CMP decisions do not specify the shape of areas, neither for forest, nor for those areas on which land-use
change events occur. However, the GPG-LULUCF specified that it is good practice to define a minimum width
in conjunction with a minimum area. Square areas that meet the 0.05 to 1 ha range would be 22.36 m to 100 m
on each side. But a rectangle that is 10 m wide and 1,000 m long is also 1 ha in area, as is a 5 m wide and 2,000m long rectangle. Therefore, a treed shelterbelt or any other strip of trees that exceeds the minimum width andarea defined by the country can be considered a forest and any forest cleared for "linear events" that exceed theminimum width and area, such as roads, transmission right-of-ways, or pipeline corridors are considered
deforestation. When such clearing has occurred since 1 January 1990, it is treated as D under Article 3.3.
For example, if a country selects 1 ha as the minimum area of forests and further specifies that these areas are
square, then a 20 m wide corridor cut through a forest with 100% tree crown cover, will reduce tree crown cover
to 80%. This is higher than the range of tree crown cover (10 – 30%) that could be selected by a Party.
Therefore the residual area is defined as forest, and even when this corridor through the forest is cut since 1990,
it would not constitute a deforestation event. If this "only" 20 m wide clearing is part of a corridor that stretches
for many kilometres, such as a transmission right-of-way or a pipeline corridor, the total corridor area is muchgreater than 1 ha. Therefore the definitional criteria applied to specify the shape of the forests of the area of landuse change events can have a large impact on the amount of land reported under Article 3.3 and FM.
It is therefore good practice for countries to include, within their report on the choice of forest definitions, adescription of the definitional criteria which are used to identify forests and areas on which land-use change
occur. It is also good practice to apply these criteria consistently to the identification of land-use change events
that have occurred since 1990, or the start of the second CP for conversion of natural forests to planted forests
and CEFC. For instance, these criteria can simply be defined as the minimum width that will be accepted for a
forest and an area subject to a land-use change event. Then the minimum length of the area follows from the
combination of width and the chosen parameter for minimum area which can constitute a forest. For example, if
the size were defined as 1 ha, with a minimum width of 20 m, then a rectangle of minimum width has to be atleast 500 m long to meet the 1 ha size requirement.
It is good practice to report as FM the impacts on carbon stock changes of "linear clearing events" narrower than
the selected minimum width criterion for deforestations events. Examples of such clearing events can include
skid sites, forest roads, or seismic lines. Similarly, it is good practice to report the carbon stock changes inshelterbelts that are narrower than the selected minimum width criterion and are therefore not forest, if theseshelterbelts are within lands subject to elected CM, GM, RV or WDR activities.

2.2.6.2

S OURCES OF DATA FOR IDENTIFYING LANDS AND
ADDITIONAL NEW REPORTING REQUIREMENTS FOR THE
SECOND CP

The needs for the reporting of lands subject to activities under Articles 3.3 and 3.4 and other reporting
requirements have been outlined in the previous sections. The data and information available to a country tomeet these needs will largely depend on national circumstances, including the investments made into theappropriate national GHG inventory systems, for monitoring, reporting, and verifying emissions and removals.
These include the land and forest inventory systems already in place and the additional measures a country
chooses to implement to meet the reporting requirements. The data and the acquisition methods must ensure thatthey are reliable, well documented methodologically, at an appropriate scale, and from reputable sources.
In very general terms there are three major options and their combinations that can be taken to meet the
information needs:To use information from existing national statistics and land-use and forest inventory systems.

To implement a monitoring and measurement system to obtain information on land-use conversions, forest
management, natural disturbances and other relevant activity data.

To implement a system by which land management activities are reported to government agencies, e.g. an
incentive program could be established that encourages land managers to report AR activities that are
difficult to detect through remote sensing, in particular in regions with slow growth rates, such as boreal
forests. To ensure integrity, such a reporting system should include verification and auditing procedures.

It is likely that in most countries the existing forest inventory systems will be combined with additional sourcesof information and in-country monitoring activities to meet all the land reporting requirements of the KP, andthat, with varying degrees of incremental efforts, additional information will need to be obtained through2013 Revised Supplementary Methods and Good Practice Guidance Arising from the Kyoto Protocol

2.21

Chapter 2: Methods for estimation, measurement, monitoring and reporting

monitoring or in-country reporting systems. The optimum approach to obtaining the required data may involve
combinations of the three options. For example, national forest inventory systems with 5 to 10-year periodic remeasurement intervals may not be adequate to meet the reporting needs on annual area disturbed by wildfires,and the associated non-CO2 emissions. Data from fire monitoring systems could be used to augment the
information obtained from forest inventories. Data from forest management records could be used to estimate
non-CO2 emissions associated with fertilization. Or a country could determine that it would be most efficient to
combine an activity reporting system to identify lands subject to AR (which can be difficult to detect using
remote sensing in regions with slow growth rates), and a monitoring system to identify lands subject to D (which
are more readily detected).
Remotely sensed data are increasingly contributing to land cover and land-use monitoring, to forest inventory
systems, and to activity reporting systems as data for certain sensors become cheaper or freely available, and ascomputing power and algorithms are improving10. Nevertheless, considerable efforts, infrastructure and expertiseare required to process the large volumes of remote sensing data and to derive estimates of carbon stock changes
and non-CO2 GHG emissions and removals from the remotely sensed data on land cover and land-use changes.
In particular estimates of GHG emissions and removals associated with belowground biomass, dead organic
matter and soil organic matter, which are carbon pools that cannot be directly inferred from remote sensing ofland surface characteristics, will require additional efforts and investment. The use of remote sensing to construct
and assess forest attribute maps is described by McRoberts et al. (2010) and McRoberts and Walters (2012).
Information about the use of FAO data in GHG inventory preparation can be found in IPCC (2010b).

USE OF EXISTING INVENTORIESCountries that maintain detailed forest and other land-use inventories or collect annual or periodic spatial land
statistics may be able to identify lands affected by Article 3.3 and 3.4 activities since 1990 from their inventories.
This, however, will only be possible if the national inventory and data collection systems meet stringent
technical requirements. The systems should be able to define the land use and forest area in 1990, have an update
cycle that is sufficiently short to capture land-use change events between relevant periods (1990-2007, 20082012, and 2013-2020) and be of sufficient spatial resolution to identify events of the size of the minimum forest
area chosen by the country, i.e. 1 ha or smaller. Also, the sample plots within a “boundary” need to begeoreferenced and used repeatedly during future monitoring to allow tracking of land over time. If the latter is
not possible, e.g. because monitoring procedures were changed, it is good practice to develop computational
procedures, which allow conversion of data between the sampling schemes or, at least to have a method, whichallows to map the data from a previous to a successor sampling scheme (see also Sections 2.4.1 Developing aconsistent time series and 2.4.2 Recalculation).
If countries use Approach 3 to carry out inventories, with spatially-explicit and complete geographicalinformation of land use and land-use change, the inventories will be sufficient to meet the reporting requirements
provided that the minimum grid or mapped polygon meets the area criterion selected to define forest. Forest
inventories in large countries often do not record polygons (i.e. the minimum mapping unit) less than, forexample, 3 ha in size. The requirement to identify AR and D or natural forests to planted forest conversion
events at a resolution of 0.05 to 1 hectares can be met, however, with additional statistical analyses to establish
the area subject to AR and D or conversion of natural forests to planted forests events that occurred in units lessthan 3 ha in size. One possible approach could be to determine the size-class distributions of AR and D events inthe country, using a statistical sampling approach. The proportion of the area of AR and of D events that is
between 0.05 – 1 ha and the minimum mapping unit in the inventory (in this example 3 ha) can then be applied
to estimate the area of AR and D events from the 3-ha resolution inventory. For example, if the 3-ha resolution
inventory shows that there have been 1,000 ha of AR events in units of 3 ha or larger, and the sample-based sizeclass distribution of AR events shows that on average 5% of the AR events is in areas of size between 0.05 – 1
ha and 3 ha, then the 1,000 ha represent 95% of the total AR area (and the total is estimated to be 1,000 • 100/95= 1,052.6 ha). It is good practice to document the statistical validity of the sample-based size-class distribution,and its regional and temporal variation. It is also good practice to avoid double counting when combining two
different sources. Note that this approach to augmenting existing inventory information also has implications forthe determination of carbon stock changes: since these 5% of the area are not geographically referenced, only
statistical methods such as regional averages can be used to determine their carbon stock changes and trace theirfate, once they are included under Article 3.3 or 3.4, over time. An alternative approach would be to collect thedata regarding AR, D or conversion of natural forests to planted forests in areas of size between 0.05 – 1 ha and3 ha through activity reporting but countries would need to ensure completeness and collect georeferenced
information (see below).
10

For example, to obtain such information, the intergovernmental Group on Earth Observations (GEO) is working withgovernment agencies to acquire and make freely available and accessible, relevant data and related products from remotesensing and in-situ platforms for various countries, including those subject to this supplement and, more broadly, allcountries in their reporting under the UNFCCC.

2.22

Chapter 2: Methods for estimation, measurement, monitoring and reporting

Additional monitoring and data compilation may be required to meet the reporting requirements for land-use
changes, conversion of natural forests to planted forests, WDR, and activities such as salvage logging and landuse conversion of lands affected by natural disturbances for which the emissions were not included in theaccounting.
Countries that choose an inventory-based approach for the identification of lands subject to AR activities canface the challenge that non-forest areas are not usually included in the forest inventory. In this case, countries
must ensure that their inventory system detects land-use transitions from non-forest to forest and expands theforest inventory into the newly created forest area. Some countries monitor changes from non-forest to forest bymeans of remote sensing of lands not previously covered by the forest inventory or by maintaining inventory
plots on non-forest land.

MONITORING AND MEASU REMENT OF ACTIVITIESTo meet the reporting requirements of Articles 3.3 and 3.4, countries may have to develop and implement amonitoring system for the identification and recording of land use and land-use change. Such a monitoring
system could combine a base map (or other sources of spatial information) on forest area and land use on 31
December 1989 with spatial data on land use and forest area in subsequent years. Changes in land use and forest
area can then be inferred from a time series of spatial data. This may require interpolation, for example where abase map has been derived from composite satellite images obtained over several years, as is often the casewhere cloud cover, sensor failures, or other technical reasons make it impossible to obtain national coverage fora single point in time.
Some events, such as the conversion of natural forest to planted forest, or salvage logging following natural
disturbances, are rarely spatially and temporally explicitly documented in inventories. The monitoring of these
events is important, and the monitoring time interval should be short enough to capture relevant changes.
Remote sensing monitoring can be useful, especially in large or remote areas, due to its potentially high temporal
resolution and cost-effectiveness. However, remote sensing data and their results need to be validated against insitu data to reduce uncertainties.
In many countries repeated complete (wall-to-wall) coverage of the entire country is not feasible on an annual
basis. When implementing temporal and spatial sampling strategies, it is good practice to ensure that the
sampling methods are statistically sound, well-documented and transparent, and that estimates of uncertainty areprovided (Section 2.4.3 Uncertainty assessment). Appropriate pre-stratification of the country for which sample
estimates will be developed may reduce the uncertainty.
Recent advances, such as the release of the freely available and complete Landsat archives, developments of newimage processing algorithms, and vast increases in computing power may enable the production of annual landcover change products at national, continental and global scales (Townshend et al., 2012). However, given that
land-use change often occurs on only a small fraction of the areas affected by land-cover change, additional
information and/or inferences may be required to ascertain whether a land-cover change represents a land-use
change (see Step 1.2 in Section 1.2). Moreover, special requirements such as the reporting of conversion ofnatural forests to planted forests will require additional data, for example to determine whether cover loss
occurred in natural forests and whether the regenerated forest is the result of planting. These and other special
requirements can be met through activity reporting (see below).
Where the monitoring system generates georeferenced data for natural disturbance events, this information canalso be used to track subsequent events with reporting obligations, such as salvage logging of disturbed areas or
the conversion to non-forest land of disturbed areas for which emissions were not accounted.

ACTIVITY REPORTING
Identification of lands that are subject to activities under Articles 3.3 and 3.4 can be achieved through theimplementation of an activity reporting system. For example, since AR events are often difficult to detectthrough remote sensing and often occur outside the area of existing forest inventories, a country may choose to
identify these lands through an activity reporting system that encourages land managers who afforested nonforest land to report such activities to the appropriate national agency. Instead of trying to detect AR events frominventory or monitoring systems, countries can request those individuals or agencies to report the AR activities.
Activity reporting may also be most efficient where information about land use is required that may not bereadily determined from remote sensing, such as CM, or GM. Activity reporting may also be important for theattribution of land-cover change, including RV, and to identify where observed conversions to and from forest
are linked through the provision of CEFC. Reporting systems can usefully include spatial databases that facilitate
the compilation of the pertinent activity information. It is good practice to include the location and the area of
the activity, and information relevant to the estimation of carbon stock changes, such as site preparation methods,
tree species planted, and the projected and actual carbon stocks for the land.

2.23

Chapter 2: Methods for estimation, measurement, monitoring and reporting

Activity reporting may be necessary for the identification of AR, D, conversion of natural forests to planted
forests, or CEFC where the area of the activity is larger than the minimum area selected for the forest definition
under the KP but is smaller than the minimum mapping unit in the forest inventory and may therefore goundetected. Coupled with high resolution remote sensed images, activity reporting can provide georeferenced
information and detailed description of land cover change for small areas and sample plots.
It is good practice for countries that rely on activity reporting systems, to put into place methods for internal
auditing and verification to ensure that activities are neither over- nor underreported. Administrative information
on programmes or subsidies for AR activities alone may not include information on plantation establishment
success. Spatially explicit information, i.e. either the delineation of the lands, or references to a country’s
national map grid coordinates (e.g. UTM, Universal Transverse Mercator) or legal description of the land subject
to an activity, are required for the domestic audit and verification procedures applied to a reporting system.
Detailed guidance for identifying lands is provided in the following sections: Section 2.3.9.2 (ND), Section 2.5.2(AR), Section 2.6.2 (D), Section 2.7.2 (FM), Section 2.7.7 (CEFC), Section 2.9.3 (CM), Section 2.10.3 (GM),
Section 2.11.3 (RV), and Section 2.12.3 (WDR).

GENERIC METHODOLOGICAL ISSUES FOR
ESTIMATING CARBON STOCK CHANGES AND
NON-CO2 GHG EMISSIONS

Once the areas subject to activities under Articles 3.3, and 3.4 have been determined, the carbon stock changes
and non-CO2 GHG emissions on these areas must be estimated following the methods outlined in Volume 4 ofthe 2006 IPCC Guidelines, the Wetlands Supplement and this KP Supplement.
Coverage of activities under Articles 3.3 and 3.4 requires an estimation of all carbon stock changes, andemissions and removals of non-CO2 GHGs from all lands subject to the included activities and for all carbon
pools with discretionary omission of those that are not a source of carbon, with higher-tier methods used for key
categories. Parties do not have discretion in the exclusion of the HWP pool11. The GHG emissions and removals
will be estimated regardless of their cause, such as growth, decomposition, harvest, natural disturbances, or theestablishment of equivalent forest. In the case of natural disturbances on AR or FM lands, the emissions andremovals shall be estimated and reported12 but countries can elect to exclude these emissions and subsequent
removals from the accounting in years where the emissions from disturbances are above the background levelplus the margin (See Section 2.3.9.6 for details). The carbon stock changes, and emissions and removals of nonCO2 GHGs for which a Party elected to apply the CEFC, need to be reported and accounted under FM.
The methodology used to estimate carbon stock changes and GHG emissions and removals for any particular
year depend on the land use in the current and in prior years, because shifts in categories or land uses can occur
over time. Therefore, different methodologies may be applied to different lands reported within one Article 3.3
or Article 3.4 activity.13 The methodology used to calculate GHG emissions or removals associated with a given
year should correspond to the actual land use on that land in that year, supplemented by additional
methodologies to account for past land uses and changes in land use, where appropriate. If the land in the current
year is not subject to an Article 3.3 activity, FM or an elected Article 3.4 activity, and if a reporting requirement
was not established through such activities in prior years, then the emissions and removals for that land are notreported under the KP.
The generic methods of estimating the carbon stock changes, for all pools to be reported (see below), aredescribed in Chapter 2, Volume 4 of the 2006 IPCC Guidelines. This section provides supplementary guidance
applicable to all activities under Articles 3.3 and 3.4. Guidance for specific activities can be found in Sections
2.5 to 2.12. Methodological updates for mineral and organic soils14 include:

Mineral Soils
The inventory calculations are based on land area and lands that can be stratified by climate regions and default
soils types as shown in Table 2.3, Chapter 2, Volume 4, 2006 IPCC Guidelines. This table presents default
reference (under native vegetation) soil organic carbon stocks for mineral soils (tonnes C ha-1 in 0-30 cm depth).
Countries following Tier 2 methods may also refer to data provided in Batjes (2011). It is good practicewhenever possible to verify soil carbon stock reference values by comparison with results from fieldmeasurements.

Organic soils
The Wetlands Supplement contains updated and new methodological guidance for estimating GHG emissions
and removals from drained and rewetted organic soils.

2.3.1

Pools to be reported

The 2006 IPCC Guidelines provide methodologies for the estimation of the carbon stocks and stock changes infive carbon pools: above and below-ground biomass, dead wood, litter and soil organic carbon. (Table 1.1,
Chapter 1, Volume 4, 2006 IPCC Guidelines). Decision 2/CMP.7 introduced the additional requirement to reportand account for carbon stocks and stock changes in HWPs (see Section 2.8). Decreases in one pool may be offset
11

Paragraph 26 in Annex to Decision 2/CMP.7

12

Paragraph 33 in Annex to Decision 2/CMP.7

13

For example, two lands may both be in the cropland management activity. However, one of them may have resulted fromgrassland conversion into cropland, the other from continuing cropland management, so that the GHG assessment methods
need to take account of differing values of soil carbon resulting from their different management histories.

Chapter 2: Methods for estimation, measurement, monitoring and reportingby increases in another pool, e.g. biomass pools decline after a disturbance but litter and dead wood pools canincrease. Thus the change in a single pool can be greater than the net change in the sum of the pools.
Once the individual pools have been estimated and reported for a specific area, the sum of the carbon stockincreases or decreases in the five pools and HWP is calculated. Any net decrease in carbon stocks is converted tothe equivalent CO2 emission in the reporting tables (see the Annex to this Chapter) and any net increase isreported as the equivalent CO2 removal. Carbon stock changes are converted to CO2 emissions and removals by
multiplying the net carbon stock change by 44/12 (the stochiometric ratio of CO2 and C) and by changing thesign: a decrease in carbon stocks (negative sign) leads to an emission to the atmosphere (positive sign) and viceversa. Chapter 1 in Volume 4 of the 2006 IPCC Guidelines provides clear definitions of carbon pools (see Table
1.1). If national circumstances require modifications to those definitions, rationale and documentation should be
provided for these modifications and the criteria used to distinguish between carbon pools. It is good practice toprovide such information on both the individual pools included in the reporting, and the total carbon stockchange of the six pools, including HWP.
Decision 2/CMP.7 specifies that a Party may choose not to account for a given pool, except for HWP, in a CP, if
transparent and verifiable information is provided that the pool is not a source,15 although once a pool has been
included in the Forest Management Reference Level (FMRL) inscribed in the Appendix to Decision 2/CMP.7,
for consistency reasons it is good practice to report this pool during the CP, irrespective of the pool being a sinkor a source (see section 2.7.5.2). Good practice in providing verifiable information, which demonstrates that
excluded pools, if any, are not a net source of GHGs, can be achieved by one or more of the four approaches
listed below:

Representative and verifiable sampling and analysis to show that the pool has not decreased. It is goodpractice under this approach to measure the pool at a sufficient number of sites, within regions, to provide
statistical confidence, and to document the sampling and research methods;



Reasoning based on sound knowledge of likely system responses. For instance, if an established cropland
without litter or dead wood carbon pools, i.e. not orchards or agroforestry systems, is converted to forest
land by AR, the dead wood pool cannot decrease, because there is no deadwood in that cropland; as is
typically the case in areas with annual crops;Surveys of peer-reviewed literature suitable for the activity, ecosystem type, region and pool in question (forexample, showing that in the climatic situation and with the soil types of the region, AR of cropland leads toincreases in soil organic carbon stocks); orCombined methods.

It is good practice to report, wherever it is applicable, levels of confidence in estimates that led to the exclusionof a pool, and how this level of confidence was established (see also Section 2.4.3 Uncertainty Assessment).
When two or more pools are combined in the reporting, then it is good practice to report carbon stock changes
for the combined pool, unless a country can demonstrate that the aggregated pool is not a source.

2.3.2

Years for which to estimate carbon stock changes andnon-CO 2 GHG emissions

Decision 2/CMP.7 specifies that the carbon stock changes and non-CO2 emissions from land subject to Article
3.3 activities, FM and any elected activities under Article 3.4 be reported for each year of the CP16, beginningwith the start of the CP, or with the start of the activity, whichever is later. 17 Decision 2/CMP.7 also requires thateach area that was subject to reported activities during the first CP has to be reported during subsequent CPs andthe associated emissions and removals estimated, even if the area is no longer subject to any Article 3.3 or 3.4
activity.
This means that if the activity started during the CP, the carbon stock changes and non-CO2 emissions should bereported for the year of the onset of the activity and for each of the remaining years of the CP. If the activity
started after 1990 but before 1 January 2013, reporting of the carbon stock changes and non-CO2 emissions for
the CP should cover each year of the CP.
In summary, the area and associated carbon stock changes and non-CO2 emissions to be reported by Parties, eachyear, under each activity are:15

EXAMPLEA Party had three deforestation events reported between 1990 and the last year of the second CP:• the first occurred in 2005, i.e. before the start of the first CP - and was 1,000 ha in size,• the second in 2010, i.e. during the first CP, was 2,000 ha in size,• the third in 2015, i.e. during the second CP, was 4,000 ha in size.
This Party will report during the second CP:• for the first two years, i.e. 2013 and 2014, the total area deforested since 1990 until that date, i.e.
1,000 + 2,000 = 3,000 ha, and carbon stock changes and non-CO2 emissions that occurred on
those lands since the start of the second CP, i.e. 1 January 2013.
• for the remaining years of the second CP, the total area deforested since 1990 until that date, i.e.

EXAMPLEA Party is reporting the entire national forest area as subject to FM. There is no deforestation andthe area subject to FM is continuously increasing during the first three years of the second CP due
to expansion of forest which is not human-induced above the current timberline, adding 1,000 haannually. The area reported subject to FM activity at the beginning of the second CP is equal to1,000,000 ha.
This Party will report during each year of the second CP an additional 1,000 ha of area subject toFM, so that at the end of:• 2013 the area reported will be equal to 1,001,000 ha and associated carbon stock changes andnon-CO2 emissions, since the beginning of the year, will be reported;• 2014 the area reported will be equal to 1,002,000 ha: an initial area, 1,001,000 ha, subject to FM
since 2013 and 1,000 ha of new forest area subject to FM for the first time in this year. For the
initial area associated carbon stock changes and non-CO2 emissions, since 2013, will be reported.
For the new area associated carbon stock changes and non-CO2 emissions, since the beginning of2014, will be reported;• 2015 the area reported will be equal to 1,003,000 ha: an initial area, 1,001,000 ha, subject to FM
since 2013, an additional area of 1,000 ha subject to FM for the first time in 2014 and a new forest
area subject to FM for the first time in this year. For the initial area associated carbon stocks
changes and non-CO2 emissions, since 2013, will be reported. For the area added in 2014
associated carbon stock changes and non-CO2 emissions, since 2014, will be reported. For the newarea associated carbon stock changes and non-CO2 emissions, since the beginning of 2015, will bereported;
For each following year the Party will report lands and associated carbon stock changes and nonCO2 emissions since the year in which the lands have been reported under FM for the first time.
Countries must avoid any double counting of lands, and associated carbon stock changes and non-CO2 emissions.
Therefore, if transfers of land among categories occur, the transferred area of lands has to be subtracted from theold category and added to the new category, and the associated carbon stock changes and non-CO2 emissions bereported under the new activity. Note that there are constraints outlined in Section 1.3.
Each activity (AR, D, FM, CM, GM, RV, and WDR) may consist of a suite of practices and may begin with one
or several of these. For instance, an afforestation program may begin with planning, land purchase, producing
propagation material, etc. Practices like site preparation can also precede the planting or seeding (as a result of
which the land actually becomes a “forest”). Some of these practices do not affect carbon stocks (e.g. planning),
while others like site preparation may result in significant carbon, nitrous oxide or methane emissions. It is goodpractice to interpret the beginning of an activity as the start of in-situ carbon stock change and/or non-CO2
emissions due to any of the suite of practices. For example, if an afforestation activity includes site preparation,then it is good practice to include carbon stock changes caused by site preparation. In order to do that, one caneither a) measure the carbon stocks on the land prior to the start of any operations related to the activity (in casecarbon stock changes are estimated using multiple stock measurements), or b) make sure that the estimate of thestock change includes an estimate of the losses resulting from these site preparation practices.

2.3.3

Correct implementation of C stock change estimation
methods when areas are changing

The carbon stock-difference method outlined in the 2006 IPCC Guidelines22 requires information on carbon
stock for a given area, at two points in time. When using this method for a specific activity, it is important toensure that the area of land in that activity at times t1 and t2 is identical, to avoid confounding changes in stockcaused by area changes. Per unit of area at time t2, the annual stock change is the difference between the carbon
stock at time t2 and time t1, divided by the number of years between the inventories. If the forest area is changing,for example as a result of D, AR, or both, then carbon stock changes can occur as a result of the transfer of land
between UNFCCC or KP reporting categories (see Figure 11 in Kurz et al. (2009) for an example). Examples ofpossible approaches that can be implemented to address this issue are provided below.
Countries that use the IPCC stock-difference method for the calculation of stock changes23 need to ensure that
actual carbon stock changes are reported, and not artefacts resulting from changes in area over time. One
example that represents good practice is to implement the calculations of annual carbon stock changes whenusing any stock difference method in the following sequence: for any carbon pool of each activity, for each area,
the annual carbon stock change should first be calculated for the year of interest on the area at time t2, and thesestock changes should then be summed for all areas subject to the activity. The inverse sequence, i.e. firstsumming up carbon stocks across all areas of the activity at times t1 and t2 and then calculating the difference incarbon stocks, can result in errors if the total area at times t1 and t2 is not the same. Indeed, if the area subject toan activity increases from the beginning to the end of the reporting year, then the reported carbon stocks reflect
the transfer of area (and the associated carbon stocks) into the activity; similarly, carbon stocks will decrease, if
area is removed from an activity24. The issue is of particular concern when areas outside the reporting systementer into the reporting system. For example, if the stock-difference method is erroneously applied, the estimate
of C stock increase in soil organic matter of AR lands, which were previously unmanaged, will yield an apparent
increase in the estimate of soil C stocks due to the transfer of the entire existing soil organic matter C stock into
the AR accounting although this apparent increase does not correspond to C removals from the atmosphere.
It is good practice to distinguish clearly between C stock changes that result from area changes and theassociated transfers of C stocks among activities, and C stock changes that result in corresponding emissions toand removals from the atmosphere. It is therefore good practice to ensure that when using the stock-difference
method the area for the calculations of carbon stock differences for each activity at times t1 and t2 is identical.
Furthermore it is good practice to conduct all calculations of annual carbon stock changes and non-CO2 GHG
emissions with the area of the activity at the end of the inventory year - i.e. the area at time t2 in equation 2.5 ofChapter 2, Volume 4, 2006 IPCC Guidelines - and to use this approach consistently through time.
When land-use change events occur, the associated fluxes are reported in the new land-use category. When using
Tier 3 models and the IPCC default (Gain-Loss) method for the calculation of stock changes25 it is good practiceto ensure that the land-category attribute in the model is updated to reflect the subsequent land-use change prior
to estimating any C stock impacts from the land-use change event. This ensures that all carbon stock changes andnon-CO2 emissions that occur during a year will be reported in the new category. (See Box 1 in Kurz et al. (2009)as an example of a Tier 3 modelling approach that implements the required change in the land-use category at
the start of the year, i.e. prior to estimating any carbon stock changes and non-CO2 emissions associated withland-use changes during that year).

Because of the obligation to keep reporting any area subject to any Article 3.3 or Article 3.4 activity at any point in time
during CPs, a decrease of the area reported under an activity may only happen as a consequence of a transfer of area toanother activity, e.g. decrease of area reported under FM because of D.

A correct procedure will calculate stock changes in the three land categories:- managed forest lands that were subject to FM since the beginning of the year,- forest lands where the FM activity started during the year,- managed forest lands subject to FM that were deforested and converted to cropland in theyear.
Then, the sum of stock changes calculated for the two types of lands subject to FM will be reported
under the FM activity, while the change in stock calculated for deforested land will be reported
under D (Article 3.3).
A. Total stock-change in area subject toFM that was subject to FM in theprevious year

B. Total stock-change in area subject to

It would be incorrect, for instance, to calculate the total aboveground biomass carbon stock on the
total land subject to FM at times t1 and t2 and then subtract C1 from C2 e.g.:
C1 Total stock in land subject to FM at thestart of year

1,000,000 ha * 100 tC ha-1 = 100,000,000 tC

990,000 ha * 105 tC ha-1 + 10,000 ha * 84 tC ha-1

2.3.4

Relationship between measurement and reportingintervals

The CMP decisions specify that all emissions by sources and removals by sinks caused by Article 3.3, FM andelected Article 3.4 activities be reported annually. 26 A number of methods are available to obtain annual
estimates of emissions and removals and the annual reporting requirement does not imply that annual
measurements are necessary. This would be neither feasible nor cost-effective. In fact, although more frequent
measurement will generally decrease uncertainties, the opposite can also happen because of short-term
variability, as discussed in Section 2.3.5 (Interannual variability). Carbon stock changes for pools with highuncertainties in stock estimates, e.g. soil organic carbon, are usually not detectable on an annual or short-termbasis (Saby et al., 2008).
Broadly speaking, when countries are developing and selecting methods to meet their reporting requirements, it
is good practice to seek a balance which is affordable, makes best use of data that are already available, allows
stock changes to be verified consistently with the approaches set out in Chapter 6, Volume 1, of the 2006 IPCC
Guidelines (Section 6.10 Verification), and does not make GHG inventories susceptible to the impacts of annual
fluctuations in weather which can mask the impacts of changes in anthropogenic activities. Although Section
2.3.5 suggests that field data collection on a five-year cycle may represent a reasonable compromise, the remeasurement interval also depends on the pool and the magnitude of the expected changes relative to the spatial
variability in the pool and the uncertainties involved in pool size assessments. Data already available annually,such as planting or harvest statistics, may be combined with measurements conducted over longer time periods –which are less affected by annual fluctuations – or with data based on a five-year running mean.

2.3.5

Interannual variability

The two largest causes of actual interannual variability in GHG emissions and removals in the LULUCF Sector
are natural disturbances (such as fire, insects, windthrow, and ice storms) and climate variability (e.g.
temperature, precipitation, drought, and extreme events). Natural disturbances have large impacts per hectare in
the areas where they occur, while climate variability typically causes small changes per hectare but can affectlarge areas (Griffis et al., 2003; Kurz, 2010; Richards, 2010; Stinson et al., 2011; Li et al., 2011; Yasuda et al.,2012). Consequently, the rate of net GHG emissions or removals in a given area may vary from year to year,
and can shift between a net source and a net sink in successive years.
The third cause of interannual variability in GHG emissions and removals is the variation in the rate of humanactivities, including forest harvesting, land use, and land-use change. Variations and trends in these humanactivities are of interest because they can demonstrate the consequences of climate mitigation efforts. Estimationof the impacts of human activities and trends over time is the main purpose of national GHG inventories. It istherefore good practice to reflect interannual variability and trends in rates of human activities in the inventories
and to not use time-averaged activity data.
The ‘signal’ of the impact of human activities, including mitigation measures, on emissions and removals in the
LULUCF Sector, may not be discernible against the ‘noise’ of large interannual variability in emissions
originating from natural or indirect-human causes, because the impacts of natural disturbances and climate
variability can obscure trends in the impacts of human activities. The ability to discern the signal of changes inhuman activities from the noise of the interannual variability is, however, important when inventory estimates
are used to monitor the impacts of mitigation measures (IPCC, 2010a). The provision in Decision 2/CMP.7 thatenables countries to elect to exclude from the accounting emissions from certain natural disturbances (seeSection 2.3.9) removes some of the variability from indirect-human and natural factors.
The methodology used to calculate reported emissions and removals affects the extent to which these causes ofvariability are captured in the reporting. Lower tier methods are typically less affected by interannual variability
in non-anthropogenic drivers of GHG emissions and removals than higher tier methods. Lower tier methods inwhich estimates of emissions and removals are insensitive to variation or trends in climate or otherenvironmental conditions (such as atmospheric CO2 concentrations or N-deposition rates) are likely to estimate
lower interannual variability in emissions and removals than actually occurs. This is because IPCC default data(including those contained in the Emission Factor Database27) have been calculated by averaging data collected
over time and space to estimate representative global, regional, and ecological factors. By averaging out time and26

Note that although annual reporting is required, countries have the option to account either annually or over the entire
commitment period (see paragraph 1(h) in Annex I and paragraph 1 in Annex II to Decision 2/CMP.8).

space variability Tier 1 methods that use these IPCC default factors do not reflect interannual variability fromnatural and indirect-human induced factors.
In contrast, Tier 3 methods that use process models to calculate net primary production (NPP) and heterotrophic
respiration (Rh) as a function of environmental variability can report very high interannual variability inemissions and removals as a result of climate variability because these two fluxes (NPP and Rh) are very large.
This can introduce fluctuations in annual GHG inventories that can completely mask impacts of changes inhuman activities (Richards, 2010). Forest inventory-based modelling approaches that implement the IPCC
default approach (gain-loss method)28 and that use empirical yield tables, which are not affected by interannual
variability in climate, report lower interannual variability in GHG emissions and removals. Inventory-basedmodelling approaches represent interannual variability due to natural disturbances and human activity (e.g.
Stinson et al. 2011 show high interannual variability in emissions and removals due to variations in annual areaburned and insect infestations). Estimates of GHG emissions and removals derived from the stock-difference
method (calculating the difference in C stocks estimated from forest inventories at two points in time) report the
average annual net balance over the period between the first and second forest inventory. This approach averages
interannual variability and, without additional information, may not be able to attribute observed emissions andremovals to the drivers of emissions such as natural disturbances, environmental change or human activities.
Additional information could be derived from a continuous forest inventory design in which some data arecollected each year, or from supplementary statistics on area annually affected by disturbances.
Interannual variability can decrease as the geographical area considered increases. For example, the effects oflocal weather patterns may partially offset each other across a large country, but may be more pronounced in asmall country or within a small region of a country. There are, however, climatic processes that can synchronize
variations in weather over large regions (Ciais et al., 2005), such as global climate change or El Niño Southern
Oscillation (ENSO) events which typically occur on time scales of 3 to 7 years. Within limits, the longer themeasurement or estimation interval the more likely it is that the results will capture the true long-term averagevalue but averages can mask trends.
In addition to GHG emissions and removals during the CP, Decision 2/CMP.8 also requires estimation andreporting of GHG emissions and removals during the base year (1990 in most cases) for those elected activities
for which net-net accounting applies. The impact of this estimate for a single year could be large because it will
be compared against the estimates for each year in the CP in which this activity occurred. The direction andmagnitude of the impact depends on how the year 1990 deviated from the long-term emissions averages, e.g. as aresult of variability in natural disturbances or climate. It is good practice to use longer-term averages ofemissions and removals to represent the base year when environmental conditions in the base year (e.g. 1990)
caused major deviations in GHG emissions and removals from their longer-term (e.g. 5-year) averages. However,
it is not good practice to use averages to even out the effects of variations in the rate of human activities, such as
the variation in harvest or land-use change rates, in the base year.
Because of interannual variability in environmental conditions, extrapolation from a single year may result inincorrect conclusions about long-term trends. Conversely, interpolation of long-term trends in, e.g. forest growth
rates may result in under- or overestimation of the actual growth in a single year. Forest growth functions andyield tables used in countries with forest management planning systems are based on measurements of periodic
growth (e.g. over 5 or 10-year re-measurement intervals) and therefore incorporate and average the impacts ofpast interannual variability of environmental conditions, but could miss long-term trends in productivity e.g. due
to increases in atmospheric CO2 concentration or climate change (Briffa et al., 2008, Hember et al., 2012) One
approach that meets good practice to reduce interannual variability is to use such growth functions to estimate
biomass growth rates, because they represent the average annual growth rates and are therefore influenced little
by short-term fluctuations in environmental conditions.
Where empirical growth and yield functions are used to estimate stand growth, it is good practice to evaluate thepotential influences of interannual variability in environmental conditions, for example through comparisons ofpredicted and actual growth on a set of regionally-distributed permanent sample plots. Where the periodic (e.g.
5-year) increment is consistently under- or over-predicted, it is good practice to adjust growth estimatesaccordingly, and to incorporate the new data in updated empirical functions. Countries that use process-basedmodels to simulate annual variability in stand growth and other stock changes need to also evaluate thesepredictions against measurements of periodic stock changes on permanent sample plots and adjust thepredictions, and underlying models, where necessary. Steps outlining the appropriate use of models in GHG
inventories are further outlined in the IPCC expert meeting report on the subject (IPCC, 2010d).
It is encouraged at Tier 3 to assess and document clearly the extent to which natural and indirect-human factors
influence the time series of reported annual GHG emissions and removals in the LULUCF Sector. While suchfactoring out has been recognised as difficult (IPCC, 2003b), new methods are becoming available that can help

Chapter 2: Methods for estimation, measurement, monitoring and reporting

inform the policy community about the relative contributions of natural and indirect-human factors compared todirect human factors (Smith, 2010). Measures to reduce the reported impacts of environmental variability(including climate, trends in atmospheric CO2 concentration or N deposition) can include time-averaging ofenvironmental data over 5-10-year or longer periods when using such data in higher-tier process models.
However, because of non-linear ecological processes, average environmental conditions may not yield average
net emissions or removals.
Methods used to reduce interannual variability can also help isolate the impacts of changes in human activities
relative to a baseline. This can be achieved by calculating two time series of emissions and removals in which
only the rate of human activities differ. For example, using Tier 3 models that are responsive to climate
variability, two time series can be calculated ex post: first, the baseline emissions (with actual climate data,
actual natural disturbance rates and baseline human land use and land-use change and forest management data –the baseline could be based on historic averages or business-as-usual assumptions); and second the actual
emissions (with actual climate data, actual natural disturbance rates but actual human land use, land-use change
and forest management data). The difference between these two time series reports the impacts of changes inhuman activities because the impacts of interannual variability in climate and natural disturbances are the same
in both scenarios and cancel each other out when calculating the difference between scenarios (Kurz, 2010)29.
FM reference levels and the provision to exclude emissions from natural disturbances introduced for FM in
Decision 2/CMP.7 can affect the extent to which interannual variability is reflected in the accounted estimates of
GHG emissions and removals. Countries that elect to exclude emissions from natural disturbances will reducethe interannual variability in accounted emissions.
The impact on accounting of the use of FMRL on interannual variability will depend on the methods used to
calculate the FMRL and the actual reported emissions. Countries could introduce large bias due to interannual
variability in reported emissions if they use a FMRL that was calculated with methods that are not responsive toenvironmental variability or with average climate parameters, but then calculate actual emissions with methods
that are responsive to environmental variability (including long-term trends) or with actual climate parameters.
If a Party uses Tier 3 models responsive to environmental parameters, it is therefore good practice to use
consistent methods, including the same environmental and climate data, to calculate both the FMRL and theestimated actual FM emissions. For example, if a technical correction (see section 2.7.6) to the FMRL
calculations using Tier 3 methods used the same time series of climate parameters that are used in the calculationof the actual FM emissions, then the impacts of interannual climate variability on forest productivity (NPP) andrespiration would cancel out in the difference between the two time series.
It is good practice to document whether the methods selected for the estimation of GHG emissions and removals
are sensitive to interannual variability of environmental conditions during the CP, and to report how interannual
variation was addressed in the inventory calculations.

2.3.6

Choice of method

It is good practice to estimate carbon stock changes and non-CO2 GHG emissions from Article 3.3 or Article 3.4
activities using the methods set out in Volume 4 of the 2006 IPCC Guidelines. For all land under Articles 3.3 or
3.4, it is good practice to use the same tier or a higher tier for estimating stock changes and GHG emissions as
the one that was used for the corresponding land use in the UNFCCC inventory, following the guidance on
methodological choice and identification of Key Categories included in Chapter 4, Volume 1, of the 2006 IPCC
Guidelines.
Whenever a category is identified as key in the UNFCCC inventory, it is good practice that the associatedactivity under the KP also be treated as a Key Category 30 . In the identification and documentation of Key
Categories under the KP it is also good practice to include a qualitative assessment, because there is not always
an unambiguous correspondence between the UNFCCC categories and KP activities. A country may also
undertake Approach 2 for Key Category analysis (see Section 4.3.2, Volume 1 of the 2006 IPCC Guidelines) to
identify the Key Categories of their inventory including the KP activities.
Table 2.1.1 can be used to establish the relationship between land categories and KP activities for purposes ofidentifying Key Categories under Articles 3.3 and 3.4 of the KP. The first row of Table 2.1.1 lists the land usesof the 2006 IPCC Guidelines. For each land use there are two land-use categories in the 2006 IPCC Guidelines:‘land remaining in the same land-use category’ (e.g. Cropland remaining Cropland) and ‘land converted to29

While there can also be an interaction between climate change and FM activities, the incremental emissions or removals
resulting from this interaction can be attributed to the management activity, as without it the interaction would not haveoccurred.

30

This applies also when there only are partial overlaps with the UNFCCC inventory.

Chapter 2: Methods for estimation, measurement, monitoring and reporting

another land-use category’ (e.g. Forest Land converted to Cropland). These land-use categories may have beenused in the Key Category analysis of the UNFCCC inventory31. In Table 2.1.1, for a given column, i.e. a final
land use, the entries in the rows show which KP activities could have occurred on that land. In particular,
elements on the sub-diagonal of Table 2.1.1 correspond to land remaining in the same category (e.g. Croplandremaining Cropland), while the other entries of that column show possible KP activities on land converted to thegiven land use.
If any of the land-use categories of the 2006 IPCC Guidelines is identified as key, the KP activities in thecorresponding column of Table 2.1.1 (note again the distinction of land remaining in the same category in the
sub-diagonal cell, and land converted to the given land use) could initially be considered key. However, as insome cases several KP activities potentially can be key, it is good practice to examine qualitatively which of thepossible activities actually are key. For example, if land converted to Grassland was identified as key, this caninvolve D, RV, GM, WDR, or land-use changes not covered by the KP. The land area affected by RV or WDR
may be much smaller than the land area of the land use category in which it occurs and in which other activities
may also occur. If this is the case, and if RV is identified as potentially key according to Table 2.1.1, thencountries may separately assess the importance of GHG emissions and removals in RV compared to the otheractivities which occur in the same land-use category. It is good practice to explain and document which of thepotential key categories are identified as key for KP reporting.
In addition, it is good practice to take into account the following considerations in the key category
determination for estimates prepared under Articles 3.3 and 3.4 of the KP:As shown in Table 2.1.1, several activities under the KP can occur in more than one land category of the
UNFCCC inventory. In such cases, it is good practice to consider the total emissions and removals from theactivity for purposes of the key category analysis. When this approach is needed, an activity is considered
key if the emissions or removals from the sum are greater than the emissions from the smallest category that
is identified as key in the UNFCCC inventory (including LULUCF).



If, when using the quantitative methods, a category is not identified as key for the present year but it isanticipated to increase strongly in the future, it is good practice to identify it as key. This could, for example,
occur with a large- scale afforestation program producing only small sinks in initial years, but with the
expectation of larger sinks in future years.

In some cases, it is possible that the emissions or removals from an activity under the KP could exceed theemissions or removals of the associated category in the UNFCCC inventory. In such a case it is goodpractice to identify the KP activity as key if its emissions/removals exceed the emissions of the smallest
category that is identified as key in the UNFCCC inventory (including LULUCF).

It is good practice to determine for each Key Category, where relevant (see Table 4.1 in Volume 1 of the 2006
IPCC Guidelines), whether any subcategory or pool is particularly significant. Usually, for this purpose, thesubcategories or pools are ranked according to their contribution to the aggregate Key Category. Those
subcategories or pools that contribute together more than 60 percent to the Key Category are consideredparticularly significant. For example, if CM has been elected and is identified as key, it is good practice toidentify which pools and subcategories are significant. It may be appropriate to focus efforts towards
methodological improvements of these most significant subcategories or pools.
Tier 1 as elaborated in Chapter 4, Volume 4 of the 2006 IPCC Guidelines assumes for Forest Land remaining
Forest Land that the net change in the carbon stock for litter (forest floor), dead wood and soil organic carbon, in
mineral soil pools is zero. However, paragraph 26 of the Annex of Decision 2/CMP.7 specifies that all changes
be accounted in the following carbon pools: above-ground biomass, below-ground biomass, litter, dead wood,soil organic carbon and HWP. With the exception of HWP, a Party may choose not to account for a given pool in
a CP, if transparent and verifiable information is provided that demonstrates that the pool is not a source.
Therefore Tier 1 can only be applied if the litter, dead wood and soil organic carbon pools can be shown not to
be a source using the methods outlined in Section 2.3.1. Tier 1 can also only be applied if FM is not considered a
Key Category, which can only be the case if Forest Land remaining Forest Land (see Chapter 4 of the 2006
IPCC Guidelines) is not a Key Category.

31

If the analysis was based on the IPCC source/sink categories (1996) the transformation will be less precise. The mapping isshown in Chapter 3, Section 3.1 of GPG-LULUCF.

2.3.7

Factoring out indirect, natural and pre-1990 effects

CMP decisions specify that information needs to be provided on whether or not anthropogenic GHG emissions
by sources and removals by sinks from activities under Articles 3.3 and 3.4 factor out removals from three
processes: (1) elevated carbon dioxide concentrations above pre-industrial levels, (2) indirect nitrogen deposition,and (3) the dynamic effects of age structure resulting from activities prior to 1 January 199032. In addition to therequirement to report whether or not these effects are factored out, those Parties that choose factoring out are
expected to also report the methods they used. For the purpose of accounting under the KP “factoring out” hasbeen addressed through a so-called net-net approach where net change in GHG emissions and removals areaccounted by comparing GHG emissions and removals during the CP with a benchmark under either a base year
or a business-as-usual scenario, which could also be a scenario in which emissions and removals are assumed tosum to zero (see also section 2.3.5 and its discussion on reducing impacts of interannual variability).

2.3.8

Reference Levels

Decision 2/CMP.6 requests each Annex I Party to submit information on its FMRL and provides guidelines forthe submission and review of information on FMRLs. Technically the FMRL is a level of GHG emissions andremovals against which the emissions and removals reported for FM during the second CP will be compared foraccounting purposes.
It is good practice to construct the FMRL taking into account historical data from GHG inventory submissions,age-class structure and the need to exclude removals from accounting in line with paragraph 1 of Decision
16/CMP.1. It is also good practice to take into account FM activities which were already undertaken, projected
FM activities under a ‘business as usual’ scenario, and continuity with the treatment of FM in the first CP, where
relevant. Finally, in the construction of the FMRL it is good practice to include pools and gases consistent withhistoric reporting and to also treat natural disturbances consistently. Details of the methodology for determining
the FMRL can be found in Section 2.7.5 of this document.
The paragraph 14 of Annex to Decision 2/CMP.7 requests methodological consistency between the FMRL andreporting for FM during the second CP when accounting for FM. According to paragraph 15 of the Annex toDecision 2/CMP.7 a technical correction shall be applied if the reported data on FM or forest land remaining
forest land used to establish the FMRL are subject to recalculations. The standard method for ensuringconsistency of time series is to recalculate the estimates using the same method for all inventory years. Thus, toensure methodological consistency according to Decision 2/CMP.7, a technical correction may be needed toensure that the same method and data (climate, model parameters, etc.) are used for the construction of the
FMRL and the reporting of FM during the CP, or at least to remove the impact of any methodologicalinconsistency when accounting. Section 2.7.6 of this document describes how to detect the need for a technicalcorrection, as well as when and how to apply a technical correction.

2.3.9

Disturbances 33

Disturbances affect the carbon cycle of forests and other lands, and may also lead to non-CO2 GHG emissions.
Disturbances can be either natural or human-induced. It is good practice that all methodologies adopted forreporting emissions from disturbances be based on the guidance provided in the 2006 IPCC Guidelines.
Emissions from natural disturbances on managed land are included in the reporting under the UNFCCC, andwere included in the accounting under the first commitment period of the KP for mandatory and elected
activities. Emissions from natural disturbances on unmanaged lands were not included in the reporting so long as
those lands continued to be unmanaged. The same rules apply for the second commitment period except that
Decision 2/CMP.7 introduces the modification that, under certain conditions, and if the Party has indicated in its
NIR submitted in 2015 that it wishes to do so34, emissions from natural disturbances that occur on land subject to
FM under Article 3.4 or AR under Article 3.3 may be excluded from accounting35. If a Party wishes to exclude

such emissions, it is required to separately calculate the emissions and removals that are subject to therequirements of Decision 2/CMP.7 for natural disturbances, and to provide transparent information regarding theestimation of annual emissions and subsequent removals. This section provides good practice guidance on theimplementation of the relevant provisions of Decision 2/CMP.7 in relation to natural disturbances, including
issues related to the background level and the margin.

2.3.9.1

D EFINITIONAL ISSUESFor the second commitment period, Parties may apply the provision for the treatment of natural disturbanceemissions for FM under Article 3.4 and/or AR under Article 3.3 as set out in the Annex to Decision 2/CMP.7.
According to Annex I to Decision 2/CMP.8, a Party’s report to facilitate the calculation of the assigned amountpursuant to Article 3, paragraphs 7bis, 8 and 8bis shall contain an indication of whether it intends to apply theprovisions to exclude emissions from natural disturbances for the accounting for afforestation and reforestation
under Article 3, paragraph 3, of the Kyoto Protocol and/or forest management under Article 3, paragraph 4, of
the Kyoto Protocol during the second commitment period, in accordance with decision 2/CMP.7. Parties are
required to calculate emissions and removals from natural disturbances subject to the provisions of Annex toDecision 2/CMP.7 (including those in paragraphs 33 and 34), and to provide transparent information on how theannual emissions and subsequent removals associated with disturbances are estimated.
For reporting and accounting under the second commitment period of the KP, Decision 2/CMP.736 provides thefollowing definition of natural disturbances:
Natural Disturbances are non-anthropogenic events or non-anthropogenic circumstances. For the purposes ofthis decision, these events or circumstances are those that cause significant emissions in forests and are beyond
the control of, and not materially influenced by, a Party. These may include wildfires, insect and disease
infestations, extreme weather events and/or geological disturbances, beyond the control of, and not materiallyinfluenced by, a Party. These exclude harvesting and prescribed burning.
For practical purposes the requirement ‘beyond the control of, and not materially influenced by a Party’ replaces
the anthropogenic/non-anthropogenic test as stated in the first sentence cited above, which may be difficult toestablish, e.g. in the case of wildfires whose immediate cause may be difficult to determine. Decision 2/CMP.7
provides a list of examples under which the provision of natural disturbance may be applied:Wildfires: Wildfires occur in many forests and interact with the functioning of the forest ecosystems inwhich they occur. Wildfires can be important to the functioning of forest ecosystems, but they can also have
undesirable environmental, social and economic impacts. Fire regimes (fire intensity, frequency and seasonof the occurrence (Gill, 1975)) can have significant impacts on forest carbon stocks across considerable
spatial and temporal scales (King et al., 2011). Recent studies on wildfires and forests include: Hirsch andFuglem (2006); Williams and Bradstock (2008); Swetnam and Anderson (2008); Girardin et al. (2010).



Insect pests and disease infestations: Diseases (pathogens such as fungi, phytoplasma, or virus, cf. page
4.74 in Chapter 4, Volume 4 of the 2006 IPCC Guidelines) and insect pests can influence ecologicalprocesses and substantially affect large-scale regional GHG balances (Kurz et al., 2008; Hicke et al., 2012).
Outbreaks of forest diseases and pest insects can also have significant negative economic, social andenvironmental impacts on forested lands. Recent studies on insect and disease infestations in forests include:
Canadian Council of Forest Ministers (2012a, 2012b and 2012c); Raffa et al. (2008); Bentz et al. (2010).



Extreme weather events: Extreme weather events can involve droughts, floods, heavy and wet snowfall,avalanches, ice, and strong winds, occurring either as a single event or in combinations such as ice storms(Lindner et al., 2010; Yamashita et al., 2002; Allen et al., 2010; Kato 2008, Kramer et al., 2008; Bebi et al.,2009; Phillips et al., 2009; Chambers et al., 2007, Fujimori et al., 1987). Besides causing emissions e.g.
through the decay of dead organic matter (DOM) following storm damage or stem breakage due to highsnow loads, extreme weather events can negatively affect forests, making them more susceptible to othernatural disturbances. For example, there is a higher incidence of wildfires after drought periods.

Geological disturbances: Geological disturbances may include volcanic eruptions, landslides, tsunamis, andearthquakes (Kamijo and Hashiba, 2003; Viña et al., 2011).

Decision 2/CMP.7 requires Annex I Parties that apply the provisions for natural disturbance to FM under Article
3.4, and/or to AR under Article 3.3 of the KP to provide transparent information, inter alia, that demonstrates
that the occurrences were beyond the control of, and not materially influenced by, the Party in the commitment

period, by demonstrating practicable efforts to prevent, manage or control the occurrences that led to theapplication of the provisions contained in paragraph 33 of Annex to Decision 2/CMP.737.
Such practicable efforts include but are not limited to:Reducing the likelihood of the disturbance occurring, by preventive measures or modifying factors
related to the occurrence or propagation of the disturbance. Examples include public information
campaigns or fire bans during high-risk fire seasons. Some of the actions taken in this regard maythemselves cause emissions which need to be estimated as part of the management practice. For
example, thinning to increase stand stability against storm damage, prescriptive burning to reduce theamount of combustible material, or introduction of firebreaks to make the spread of fire less likely.

Managing or controlling the disturbance during its occurrence. This may be facilitated through theimplementation of monitoring programs and early warning systems, firefighting operations, integrated
coordination with fire squads, etc.

Depending on national circumstances, particularly the organizational, administrational and governanceresponsibilities, examples of transparent and verifiable information demonstrating these efforts could include,
but are not necessarily limited to:

A national or sub-national (regional, provincial, community) level strategy, a forest policy, FM plan orfire management policy or plan that is valid and enforced for the region where the disturbance occurred,
and that defines a national or sub-national strategy for managing the types of natural disturbance that
led the Party to apply the provision for natural disturbance38;

Information showing that the Party took practicable efforts to manage or control the individual
disturbances included under the natural disturbance provision (for example, expenditures on the fire
suppression effort and/or the incident management plans for the disturbance, and their relationship tototal budget for FM forest).

It is good practice to demonstrate that the strategy has been implemented, or is in the process of implementation,
when a Party indicates its intention to apply the natural disturbance provision.
In some instances it may not be practicable to prevent, manage or control the disturbance. When a Party wants toinclude such events or circumstances under the natural disturbance provision, it is good practice to provide
transparent and verifiable information demonstrating that no practical action could be taken to prevent, manage
or control the occurrences of the event or circumstance to comply with paragraph 34(d) of Annex to Decision
2/CMP.7.

2.3.9.2

C HOICE OF METHO DS FOR IDENTIFYING L AND SUBJECT TO
NATURAL DISTURBANCE

This section provides guidance and examples to help Parties choose an approach for identifying lands that are
subject to natural disturbance. It has linkages with Section 2.2 that addresses the area identification, stratification
and reporting.
Annex I Parties that choose to apply the natural disturbance provision outlined in Decision 2/CMP.7 need to beable to meet all of the requirements set out in paragraph 34, (a) to (f) of Annex to Decision 2/CMP.7. This
includes providing transparent information ‘Showing that all lands subject to paragraph 33(a) and (b) … are
identified, including their georeferenced location39, year and types of disturbances’ (paragraph 34(a)); ‘Showing
how annual emissions resulting from disturbances and the subsequent removals in those areas are estimated’(paragraph 34(b)); ‘Showing that no land-use change has occurred on lands for which the provisions inparagraph 33 … are applied and explaining the methods and criteria for identifying any future land-use changes
on those land areas during the commitment period’ (paragraph 34(c)); ‘That demonstrates that the occurrenceswere beyond the control of, and not materially influenced by, the Party in the commitment period, bydemonstrating practicable efforts to prevent, manage or control the occurrences that led to the application of theprovisions contained in paragraph 33…’ (paragraph 34(d)); ‘That demonstrates efforts taken to rehabilitate,

Consistent with the treatment in paragraph 6(b) of Annex to Decision 15/CMP.1, georeferencing is taken to refer to thegeographical location of the boundaries of areas including disturbances. The requirements of paragraphs 33 and 34 ofAnnex to Decision 2/CMP.7, e.g. on demonstrating whether land-use change or salvage logging have occurred on disturbed
areas, mean that ancillary data may also be required.

where practicable, the land for which the provisions in paragraph 33 …are applied’ (paragraph 34(e));‘Showing that emissions associated with salvage logging were not excluded from accounting’ (paragraph 34(f)).
Parties also need to be able to reflect the treatment of emissions and removals on these lands in LULUCF
accounting for subsequent commitment periods (paragraph 36 of Annex to Decision 2/CMP.740). All of theserequirements are linked to the identification of lands that are affected by natural disturbances, consistent with theguidance set out in this Chapter and in Chapter 1.
For lands subject to Articles 3.3 and 3.4, Section 2.2.2 outlines Reporting Method 1 and Reporting Method 2. As
discussed in Section 2.2.4, these Reporting Methods are not the same as the underlying methods used to identify
land areas for GHG inventory purposes, although there are linkages between them. Reporting Method 1 entails
delineating areas that include multiple lands and assessing the respective contribution of relevant activities (orconditions) to the total emissions from these lands; it is often associated with the application of statisticalsampling approaches to land identification. Reporting Method 2 is based on the spatially explicit and complete
geographical identification of all lands subject to a single activity (or condition) and entails wall-to-wall mapping,which is frequently associated with the application of remote sensing41 techniques. Similarly, identification oflands that are subject to natural disturbance can be undertaken with statistical sampling approaches, or via wallto-wall mapping and ground-based surveys, carried out solely or in combination, and supported as necessary by
relevant ancillary data.
Estimating the area affected by the disturbance requires, for each disturbance type, that the:i.

Proportion of affected area is assessed accurately if Reporting Method 1 is used and that each affected area
is identified as being disturbed with georeferenced location, year and types of disturbances, when Reporting
Method 2 is used, andii. Methods and algorithms used for detecting disturbances and disturbance type are suitable for theidentification of areas affected by disturbances in a manner consistent with the Party's definition of forests
used for reporting under the KP, and that respective area or areas of land be identified in subsequent years.
General guidance on this topic is provided in Chapter 3 in Volume 4 of the 2006 IPCC Guidelines. Fuller etal. (2003) discusses possible issues that are related to this.
Statistical sampling schemes do not provide delineation of disturbed areas directly, but rather an estimate of thetotal disturbed area by means of representative sample plots that were affected by the disturbance (refer to
Chapter 3 in Volume 4 of the 2006 IPCC Guidelines for guidance on sampling and area estimation).
Identification and geographical location of the disturbance events are performed on a per-plot basis. Sampling
schemes may be based, for example, on National Forest Inventory sampling grids (Tomppo et al., 2010) if theinformation provided by them is sufficient to meet the requirements in Decision 2/CMP.7, set out in paragraphs
33 and 34. Depending on the type of disturbance and its associated characteristics (e.g. area, size, anddistribution), it is good practice to intensify sampling in order to make the estimated uncertainty comparablewith the uncertainty in the overall estimation of Articles 3.3 and 3.4 forest-related emissions.
When using remotely sensed data to detect changes triggered by the occurrence of natural disturbances, a Party
needs to identify the necessary temporal and spatial resolutions, and to assess the need for complementary
ancillary and/or ground truth data. Identification and assessment are specific to the type of individual natural
disturbance events or circumstances that the Party intends to consider. While, for some types of disturbance, lessfrequent but more detailed data might provide better estimates (e.g. identification of areas affected by pest
infestation), more frequent but less detailed data might be better for others (e.g. when identifying fire hot spot
areas). Decisions concerning which data sources (e.g. spatial resolution of satellite imagery) will be used shouldtake into account the specific characteristics of the type of disturbance (e.g. percentage loss in forest crown cover
due to pest infestation). In addition, the timing of the surveying and of the analysis of the data is also relevant toensure that the data capture the effect of the natural disturbance, rather than seasonal changes. For instance, if theanalysis of the data occurs shortly after the occurrence of a discrete disturbance event, it is very likely that thechanges on the ground will result from the event itself. Otherwise, the data may be confounded with land-use
change, annual phenological and climatic differences, and/or other factors that may influence the pre- and postdisturbance conditions. It is therefore good practice for the Party to indicate how the remotely sensed data areused to identify the changes caused by the actual disturbance event, rather than other phenomena.
When considered individually, any approach may have strengths and limitations. For example, wall-to-wall
approaches based on remotely sensed data may not discriminate among losses of tree cover associated withharvesting (either planned clear cut or salvage logging) and those associated with natural disturbances, while
systematic sampling grids of existing forest inventories may not have an adequate sample size, design and40

frequency to reliably identify the year of the disturbance or the affected area with the level of precision andaccuracy desired by the Party. For both wall-to-wall mapping and statistical sampling techniques, existing
national approaches for land identification may need to be adjusted and improved in order to fulfil therequirement for identification of lands that are subject to natural disturbance, including their georeferenced
location, year and types of disturbances. Hybrid approaches, using a set of different types of data, may facilitate
the fulfilment of the relevant requirements in Decision 2/CMP.7. The Party’s choice as to which approach anddata to use for land identification will depend on national conditions in land under FM and/or AR, theinventories and surveys already in place, and the type and magnitude of the disturbance(s) to be assessed (seeBox 2.3.4 for examples). It is good practice for Parties to present information demonstrating the suitability of themethods and approaches used to identify the lands affected by natural disturbance, consistent with therequirements of paragraph 34(a) of Annex to Decision 2/CMP.7, as well as information on how the provisions
concerning salvage logging and land-use change following such disturbances are monitored. Ancillary data may
be needed (e.g. concerning disturbance characteristics, location and management activities), and this may beprovided by amending or tailoring an existing inventory scheme to detect deforestation events in a way that also
assesses whether land-use change has occurred on previously disturbed lands, or by incorporating the detectionof salvage logging in harvest records as well as by collecting completely new data.

EXAMPLES OF APPROACHES FOR IDENTIFYING LANDS AFFECTED BY NATURAL DISTURBANCES

Example 1: Permanent sample plots with repeated measurements
A Party conducts a national forest inventory (NFI) based on a set of permanent sample plots, witha predefined sampling design, that regularly provide data, and estimates both the emissions and thearea of land-use changes by using information and data collected on the sample plots.
Requirements: This approach requires that representative permanent sample plots with apredefined sampling design and regular measurement intervals be available. Guidance on sampling
approaches, including sample size, is provided in Chapter 2 in Volume 1 and Annex 3A.3, Chapter
3 in Volume 4 of the 2006 IPCC Guidelines. Measurements should provide data for the parametersof interest, including the disturbance type and year of occurrence, while meeting georeferencedlocation requirements that may require ancillary data collection.
Estimation method: The annual area affected by a particular type of disturbance is estimated as
the product of the fraction of plots affected (calculated as the ratio of sample plots disturbed andthe total number of sample plots) and the total geographical area covered by the sample plots (refer
to Section 3A.3.5 in Annex 3.A.3, Chapter 3 in Volume 4 of the 2006 IPCC Guidelines). The
associated total annual emission is estimated by multiplying the area affected and the area-specific,
disturbance level- and/or disturbance type-specific emissions (CO2 and non-CO2) per unit area.
The uncertainty in the area affected by disturbance can be estimated by following standard
sampling theory (refer to Chapter 2 in Volume 1 of the 2006 IPCC Guidelines). Parties should
stratify the affected areas to allow representative sampling based on emission intensities and thengenerate the average emission accordingly. Ancillary data will likely be needed to monitor landuse change and the occurrence of salvage logging.
Potential challenges: This approach may have a high percentage sampling error associated withrare disturbance events (e.g. hurricanes, volcanic eruptions) that may be under-represented in theexisting NFI or other sampling schemes, thus requiring an intensified sampling grid. When theregular inventory return interval is not sufficient to assign a year to the disturbance (e.g. for windthrow), additional field visits or other data/methods may be required.
Example 2: Area estimation with full coverage and time series comparisons
A Party uses remotely sensed data or a complete land register-based system, the latter of which is adatabase for land use and land-use change estimation that contains information on land holdings
based on ground-based administrative systems for forestry or land use in general.
Requirements: This approach requires full territorial coverage for remotely sensed data at an
appropriate spatial resolution, as well as appropriate remote sensing techniques for assessingchanges in land cover; or a complete and up-to-date land register-based system that contains thelocation, size of parcels of land, and information on land use/land cover (for additional informationand guidance, refer to Section 3A.2.4 (Tools for data collection) in Annex 3A.2, Chapter 3 inVolume 4 of the 2006 IPCC Guidelines). The data from remote sensing or land-register based
techniques, including the classification algorithms and estimators, require calibration andvalidation using ground truth or equivalent data. Parties should demonstrate the suitability of thetechniques, including classification algorithms and estimators, by presenting well-documented andtransparent supplementary information that describes how they have been evaluated in terms ofaccuracy and precision using ground truth or equivalent data.
Estimation method: The emissions associated with areas affected by the various disturbancetypes and levels are summed. Time series measurements are then used as supporting evidence forextent and severity of disturbance. Estimation algorithms, which may need to be a function of typeand extent of disturbance, can be used.

2.40

2013 Revised Supplementary Methods and Good Practice Guidance Arising from the Kyoto Protocol

Chapter 2: Methods for estimation, measurement, monitoring and reporting

Potential challenges: Depending on the type and intensity of the disturbance, classification andmapping algorithms may have errors of omission and commission associated with area estimation,
which can lead to high absolute errors if data from several maps are combined (see Fuller et al.
(2003) for details). It may also be difficult to detect some disturbances by remote sensing (e.g.
disturbances that cause dispersed single tree mortality over large areas, such as Ash dieback42).
The land register also needs to be updated regularly to make use of the most current information.
Another challenge is the accuracy of estimation models and algorithms and ensuring theiruncertainty is within levels aimed for by the Party.
Example 3: Permanent sample plots with repeated measurements combined with remotesensing
A Party conducts a forest inventory based on representative permanent sample plots, using
remotely sensed data for stratification.
Requirements: This approach requires availability of permanent sample plots with a predefinedsampling design and regular measurement intervals and full coverage by remotely sensed data ofappropriate spatial and temporal resolutions that allow for the identification and monitoring ofdisturbance events, combined with classification algorithms consistent with the accuracy andprecision sought by the Party.
Estimation method: The total area affected by a disturbance type is determined from remotelysensed data and total emissions are estimated from the permanent sample plots that fall within the
disturbed area. Plot data with the actual estimates of emissions and the area of the strata are used tocompute the total emissions from the disturbance. Estimation algorithms based on ground variables
can also be used to generate emission estimates. The strength of this method is that it potentiallyallows for estimates of both the emission and the affected areas that are more accurate than thosein either Example 1 or 2 above. Classification algorithms will need calibration and validation,
which should be documented and their performance evaluated.
Potential challenges: This approach requires both extensive remotely sensed data and intensive
ground data-based inventory systems. Balancing and matching of the systems and methods, e.g. to
avoid double-counting, may be difficult to achieve, especially in situations where more than one
disturbance affects a given area. The use of remote sensing faces similar challenges to those
identified in Example 2 above.

2.3.9.3

E STIMATION OF CO 2 EMISSIONS AND REMOVA LS FROM
NATURAL DISTURBANCESFor the second commitment period, Parties may apply the provision for the treatment of natural disturbanceemissions to FM under Article 3.4 and/or to AR under Article 3.3 consistent with Annex to Decision 2/CMP.7.
To apply the provisions for natural disturbance, Parties are required to provide country-specific information on a
FM background level and/or an AR background level of emissions associated with annual natural disturbances(cf. paragraphs 33(a) and (b) of Annex to Decision 2/CMP.7). Parties are also required to calculate the emissions
and removals subject to the provisions for natural disturbances (cf. paragraphs 33 and 34 of Annex to Decision
2/CMP.7), and to provide transparent information on how the annual emissions and subsequent removals are
estimated. This section provides guidance for estimating carbon stock changes in order to meet theserequirements.
The incidence of natural disturbances varies spatially and temporally. Spatial variability refers to the distribution,
intensity and the size of the areas affected by disturbances: the impact of a disturbance (e.g. a strong wind and/or
insect attack) could be concentrated in a large and continuous forest area, or it could spread across small-discrete
areas, with either homogeneous or heterogeneous intensity. Temporal variability refers to the occurrence of
natural disturbances over time and the extension of post-disturbance effects over time: there may be direct
releases of carbon to the atmosphere during the disturbance (e.g. from fires), delayed emissions (due to decay
processes), and the redistribution of carbon among carbon pools (e.g. transfer to the dead wood, litter or soilorganic matter pools), which may then also decay and cause emissions in subsequent years.
There are particular considerations in relation to the estimation of the effects of natural disturbances when a
Party applies the provision for natural disturbances to FM and/or AR. These include the choice of the estimation

method and tier level, accounting for emissions associated with salvage logging, and the exclusion of removals
subsequent to the disturbance event on the affected lands.
CH OIC E OF ES TIMATI ON M ETH OD AND TI ER LEVE L
The methods for estimating CO2 emissions associated with carbon stock changes in the relevant pools are givenin the 2006 IPCC Guidelines and are elaborated in Chapter 4 in Volume 4 for above and below-ground biomass,
dead wood, litter, and soil organic matter. For HWP, estimation methods in line with Decision 2/CMP.7 areprovided in Section 2.8 of the KP Supplement.
Land subject to natural disturbance in the context of Decision 2/CMP.7 is the land that has already been
identified as land under FM or AR. The estimation of carbon stock changes and associated emissions due tonatural disturbance should therefore be consistent with, and/or complementary to, the method and tier levelapplied to each of the pools under the activities of FM and/or AR for reporting under the KP. Estimations ofcarbon stock changes due to natural disturbance should include the disturbance’s effect on carbon stock changes
in the subsequent years of the second commitment period so that reporting reflects the emissions associated withcarbon stock changes in the year they occur. This can be achieved by ensuring that the stratification, activity data,
the emissions and removals factors and other parameters used for estimates of carbon stock changes in years
beyond the date of occurrence reflect the spatial and temporal dynamics of the natural disturbance. It is also goodpractice to estimate emissions associated with carbon stock changes from natural disturbance in a mannerconsistent with the method used for the calculation of emissions in the background level, and, if that is not thecase, to conduct a technical correction of the background level and the FMRL.
When the Forest Land Remaining Forest Land category under the UNFCCC is a key category it is good practice
to apply Tier 2 or Tier 3 methodologies to estimate carbon stock changes from natural disturbance for FM; andthe same should be done for AR if the Land Converted to Forest Land category under the UNFCCC is a key
category (Chapter 4 in Volume 1 of the 2006 IPCC Guidelines). Under Tier 1, it is assumed that the net carbon
stock change in DOM is zero. Decision 2/CMP.7 specifies that the carbon stock change in all pools must be
accounted for, although, with the exception of HWPs, Parties may choose to exclude from accounting in thesecond commitment period pools which can be shown using transparent and verifiable information not to be asource43. During natural disturbance events significant amounts of carbon may be transferred to the DOM pool,which will then decay, and thus it becomes less likely that a Party could subsequently show that DOM pools are
not a source. Therefore, countries with forests that experience significant changes in disturbance regimes (which
would be the case if major natural disturbance events occur) should quantify the impacts from these changes
using Tier 2 or Tier 3 methodologies (Section 2.2.1, Chapter 2 in Volume 4 of the 2006 IPCC Guidelines).
It is good practice for methodologies to represent the effect of the particular natural disturbance event or
circumstance on the carbon stocks on the land affected by the natural disturbance. The effects of natural
disturbances that should be considered include: direct reductions in carbon stocks due to the disturbance (e.g.
release of CO2 to the atmosphere during wildfires), transfer of carbon between pools (e.g. transfer of living
biomass to the DOM pool due to wind-throw), changes in carbon stocks following the disturbance (e.g. throughthe decay of DOM post disturbance), and the dynamics and growth rate of the post disturbance forest stands (e.g.
early rapid growth in young trees that regenerate after a stand-replacing fire). The effects considered inestimation of emissions may require the appropriate stratification of the impacted area to adequately represent
the disturbance types, climate zones, ecosystems and affected parts of ecosystems, and land-use history based ondata available from national forest inventory, remote sensing and/or other sources; and appropriate estimation ofemission factors, decomposition rates and other factors and functions involved that are representative of the
disturbance event and the different strata. Remote sensing or ground-based assessments that focus on the
disturbance event can be helpful for addressing spatial and temporal variability in order to attribute carbon stockchanges due to natural disturbance to individual years. Other statistics that record, for example, salvage logging
on an annual basis may also be relevant.
Parties included in Annex I that apply the provisions for natural disturbances are required to provide transparent
information on how the emissions from natural disturbances and the subsequent removals have been estimatedduring the commitment period44. This includes documentation of the data sources and estimation methodologies
in accordance with the tier level used for applying the natural disturbance provision. Disturbance matrices 45(Section 2.3.1.1, Chapter 2 in Volume 4 of the 2006 IPCC Guidelines) can be used to define the event’s impact
on the proportion of each carbon pool that is transferred to another pool, released to the atmosphere, or removed
from forest in salvage logging and entering the carbon pool of HWP.

EX CLUS ION OF R EMOVA L S
According to paragraphs 33(a) and (b) and 34(a) and (b) of Annex to Decision 2/CMP.7, for lands on whichemissions have been excluded from accounting under the natural disturbance provision, any subsequent
removals during the commitment period on the lands affected shall also be excluded from the accounting.
Removals are considered to be positive changes in carbon stocks due to growth of forest vegetation on the lands
subject to the provision. Removals in this context do not refer to physical removal of carbon from land affectedby a natural disturbance, or due to salvage logging (see also the definition of salvage logging in Box 2.3.5
below).
The removals on lands previously disturbed can be estimated using the methodologies provided for Forest Land
in Chapter 4 in Volume 4 of the 2006 IPCC Guidelines. It is good practice to apply estimation methodologies
that take into account the respective conditions found on the affected land following the natural disturbance
event and to show that the subsequent removals are completely estimated and that double counting is avoided.
ACCOUN TI NG FOR SA LVA G E LO GGIN G
When salvage logging occurs on land subject to natural disturbance, the carbon stock change due to salvage
logging must be accounted for and not excluded with emissions associated with natural disturbances (cf.
paragraphs 33(c) and 34(f) of Annex to Decision 2/CMP.7). Box 2.3.5 defines salvage logging in the context ofthe natural disturbance provision. The carbon stock change due to the harvest and physical removal of trees orparts of trees is treated as a loss of carbon (and consequently, as a CO2 emission) from the affected land in theyear the salvage logging occurs, and is subject to the HWP provisions of Decision 2/CMP.7 in situations where
wood derived from salvage logging can be shown to enter the HWP pool. It is good practice to assign carbon
stock changes from salvage logging to the year in which they take place.
Significant emissions from non-biomass carbon pools (e.g. soil organic matter) due to altered decay rates aftersalvage logging operations need to be included in the accounting if the required information or models areavailable to a Party and transparent information on the estimation of these emissions can be provided. The
current state of knowledge indicates the limitations of, and generally high uncertainties for, emission estimationfrom these pools under natural disturbance conditions (Chapter 4 in Volume 4 of the 2006 IPCC Guidelines),
nevertheless countries that have the necessary capacities are encouraged to capture these dynamics.

BOX 2.3.5
DEFINITION OF SALVAGE LOGGING, IN THE CONTEXT OF THE EXCLUSION OF EMISSIONS FROM NATURALDISTURBANCES

Salvage logging is the practice of harvesting and physically removing trees or parts of trees (living
or dead) from disturbed areas. This management activity is also known as salvage cutting, salvage
harvesting, sanitation cutting, and other designations. In case a Party chooses to exclude emissions
due to natural disturbances, it shall account for emissions associated with salvage logging(paragraph 33(c) of Annex to Decision 2/CMP.7). Therefore, if a Party chooses to apply thenatural disturbance provision, it is good practice to report in a transparent manner the emissions
caused by salvage logging on land subject to natural disturbance so that these emissions can betransparently accounted for. For the purposes of the provision, these emissions result from thefollowing:
1) Wood removal and fuelwood removal (and hence, carbon) from the disturbance area due toharvest and physical removal of trees or parts of trees. Wood removal and fuelwood removal istreated as a carbon loss (emission) (for example Equation 2.12, Chapter 2 in Volume 4 of the 2006
IPCC Guidelines) in the year in which it occurs;2) emissions of carbon due to the decay of dead wood discarded from salvage logging operations
and remaining on site, litter, and any significant disturbance to the soil organic matter pools; and,3) non-CO2 GHG emissions due to management activities associated with salvage logging, e.g.
burning of harvest residues.
Carbon stock increases due to gains in living biomass on the affected land are carbon removals
from the atmosphere and are not combined with emissions associated with salvage logging.

2013 Revised Supplementary Methods and Good Practice Guidance Arising from the Kyoto Protocol

2.43

Chapter 2: Methods for estimation, measurement, monitoring and reporting

A Party needs to demonstrate that the emissions from salvage logging in the area affected by the
disturbance were not included in the total emissions associated with the disturbance event, and todemonstrate how, in the subsequent years (of the commitment period), disturbed areas aremonitored for the occurrence of salvage logging, and how emissions associated with salvage
logging are estimated if salvage logging is conducted in subsequent years, after the disturbance.
This is particularly relevant to those Parties that report carbon stock changes using the stock
difference method.

2.3.9.4

E STIMATIONOF NON -CO 2
NATURAL DISTURBANCESGHGEMISSIONSFROMAs Section 2.3, Chapter 2 in Volume 4 of the 2006 IPCC Guidelines specifies, losses in carbon stocks or pools
may in particular cases imply emissions of non-CO2 GHGs. Typically, such emissions occur due to fires, forwhich the estimation methodology is provided in Section 2.4, Chapter 2 in Volume 4 of the 2006 IPCC
Guidelines, which should be applied (together with land-use specific enhancements in Chapter 4 (Forest Land) in
Volume 4 of the 2006 IPCC Guidelines). This includes the requirement to check for complete coverage of CO2
and non-CO2 GHG emissions that are related to changes in carbon stocks and pools in order to avoid omissions
and double-counting. It is also good practice to document how non-CO2 GHG (e.g. N2O) emissions due tonatural disturbances are estimated and reported.
If fire in forests contributes to a key category, it is good practice to apply higher tiers and to develop a more
complete and country-specific methodology that includes the dynamics of DOM and produces better estimates of
direct and post-fire emissions.

M ETHODOLOGICAL ISSUES SPECIFIC TO THE ESTI MATIONOF EMISSIONS AND REM OVALSDISTURBANCE PROVISIO N

UNDER

THE

NATU RAL

To satisfy the requirements of paragraphs 33(a) and (b) and 34(a) and (b) of Annex to Decision 2/CMP.7, further
guidance on methodological issues is needed concerning the estimation of the effects of natural disturbances.
These include the attribution of emissions from natural disturbance events to individual years, differentiating
natural disturbance events from management activities and monitoring lands subject to natural disturbance.
A TTRI BU TI ON O F NATUR A L D IS TUR BANC ES TO I ND IVIDUA L Y EAR S
For natural disturbances that occur during the second commitment period, it is good practice to report areas andemissions from lands subject to natural disturbances in the year in which the natural disturbance began and tocontinue reporting the emissions from these lands in the subsequent years of the commitment period.
It is good practice to attribute direct releases of carbon to the atmosphere such as those from wildfires, which
occur during the disturbance event, to the year of occurrence. Post-disturbance emissions from the DOM pools
through the decay process will, taking account of redistribution, extend over a period of time. It is good practiceto estimate these legacy emissions in the year they occur, while avoiding double counting. For example, if alarge amount of live biomass damaged during disturbances is transferred to the DOM pool, the loss of biomass
should be estimated both as a loss from the biomass pool and an input to the DOM pool. Disturbances generally
have impacts on carbon stocks for more than one year, and it is good practice to estimate, as emissions
associated with natural disturbances, the carbon emissions in the year of the disturbance, as well as legacy
emissions (e.g. decomposition of DOM) in the subsequent years of the commitment period. It is possible torepresent an insect infestation as a series of annual disturbance events, for example repeated annual defoliationof forests will lead to cumulative impacts on growth reduction, mortality and subsequent emissions (e.g.
Dymond et al., 2010). It is good practice to ,in reporting, separately identify natural disturbance lands and theirassociated emissions from the year in which the natural disturbance first occurs until the end of the commitment
period. Guidance on legacy effects associated with natural disturbances after the end of the second commitment
period is provided in Section 2.3.9.9 below.
D IFF ER ENTIA TION FROM MANAG EM EN T AC TIVI TIE S
Lands affected by natural disturbances can be similar in appearance to, and thus can be confused with, forest
areas where regular management activities have taken place. For example, areas affected by wildfire can besimilar to prescribed burning, and wind damaged areas after salvage logging can be difficult to distinguish fromclear-cuts. For the application of the natural disturbance provision the emissions from natural disturbances haveto be clearly differentiated from the emissions due to management activities. It is good practice to show that the

2.44

2013 Revised Supplementary Methods and Good Practice Guidance Arising from the Kyoto Protocol

Chapter 2: Methods for estimation, measurement, monitoring and reporting

emissions accounted for under the natural disturbance provision are unambiguously attributable to natural
disturbances and do not contain or double count emissions from regular management activities.
MON I TORI NG LANDS AF F EC TED BY NATURA L D IS TUR BANC E
Parties that apply the natural disturbance provision to FM under Article 3.4 and/or to AR under Article 3.3
should monitor the lands that have been designated as affected by natural disturbance over the second
commitment period. Monitoring of these lands will be required to:-estimate changes in carbon stocks due to post-disturbance decay and removals;-

demonstrate that, where practicable, efforts have been made to rehabilitate the affected lands;-

identify cases in which land-use change has occurred after a natural disturbance;-

estimate the amount of carbon stock that has been removed in salvage logging; and-identify lands where the natural disturbance is followed by another disturbance event, in order to avoid
double-counting.

Monitoring natural disturbances and compiling the associated data on these lands including the disturbance type,size and location is required in order to provide consistent time series information about the affected area. The
methods used in the post-disturbance monitoring of affected areas should be consistent within those used tomonitor forestry activities in general; i.e. the underlying assumptions and estimation methods should be incommon and activity data estimates should be consistent even if supplementary data are gathered from different
sources, e.g. greater use of remote sensing for disturbance monitoring.
If land-use change occurs on lands affected by natural disturbances, and on which emissions were previously
excluded from accounting, it is good practice to account for this land as being subject to deforestation in the year
the land was subject to the natural disturbance. This results in all emissions caused by the natural disturbance andland-use change being accounted for under Deforestation.

2.3.9.6

G UIDANCE ON THE DEVEL OPMENT OF THE BACKGR OUNDLEVEL AND MARGIN

Parties may exclude46 emissions from natural disturbances for FM or for AR (or both) above the backgroundlevel in years for which the emissions resulting from natural disturbances exceed a background level plus a
margin, where a margin is needed, provided that they meet all the requirements set out in Decision 2/CMP.747.
Conceptually, the background level is the annual level (a positive number or zero) for disturbance emissions
based on historical data, and the margin is a positive number or zero that should be set in conjunction with thebackground level. Because the background level is included in the FMRL, emissions from natural disturbances
up to the background level are already implicitly excluded from accounting during the second commitment
period. The sum of the background level and the margin is used to identify years (those for which emissions
from natural disturbances during the commitment period were larger than this sum) when emissions from natural
disturbances larger than the background level may be excluded from accounting. It is good practice that thebackground level and the margin be developed together so as to ensure that the exclusion of natural disturbances
does not lead to the expectation of net credits or net debits.
In order to develop both the background level and the margin, Parties can apply either the default method
described in the Annex to Decision 2/CMP.7, or alternative country-specific methods. The choice of methods
will result in different background levels and margins, but regardless of the applied method, it is good practice todevelop a background level and a margin that ensure the exclusion of natural disturbances does not lead to the
expectation of net credits or net debits (see Box 2.3.6). Given the same set of data, in cases with a higher valueof the background level and margin, more emissions are implicitly excluded and the individual exclusion ofemissions is expected to be less frequent than in cases with a lower value of the background level and margin. In
the latter case, higher costs for monitoring, estimation and reporting can be expected.
Decision 2/CMP.7 requires the development of separate background levels and margins for FM and AR. For
both FM and AR, emissions from natural disturbances may occur as a result of several types of disturbances. In
estimating the background level and margin it is good practice to combine emissions from different disturbance46

types, and then to develop one overall background level and margin for FM, and one for AR, if Annex I Parties
choose to apply the natural disturbance provision to both FM and AR.
Decision 2/CMP.7 requires that the background levels be constructed using consistent and initially complete
time series that contain, but are not limited to, 1990–2009 annual emissions that are associated with natural
disturbances48. The period for this time series of historical emissions is referred to as the calibration period.
To develop background levels and margins, it is good practice to apply the stepwise procedure49 described below.
S tep 1: D efin e t he type s o f na tura l d ist ur ban c es that th e Par ty wis h es to exc lu de fro ma cco unt ing
It is good practice that Parties define, and report in their NIR due in 2015, and in their report to facilitate thecalculation of the assigned amount (see footnote 46), the natural disturbance types (which may include wildfires,
insect attack and disease infestations, extreme weather events and/or, geological disturbances) whose emissions
they wish to exclude from accounting during the commitment period under the natural disturbance provisions.
Disturbance types may be subdivided as needed. For example, extreme weather events could be subdivided intowind storms and floods. These disturbance types can include rare events (such as volcanic eruptions) that may
not have occurred during the calibration period.
S tep 2: Estab lish a con s is te nt and in it ia lly com p le te t im e s er ies fo r th e ca libr at ion
p eriod fo r e ac h d istu rba nc e ty pe
For each disturbance type considered by the Party, a time series of annual emissions that are associated with the
disturbance type needs to be established for the calibration period. The emissions are entered into Table 2.3.1 forFM and in Table 2.3.2 for AR both for each year of the calibration period and for each type of disturbanceconsidered, and are used for subsequent calculations and for reporting. In order to accurately establish thebackground level, Parties are encouraged to use the longest available time series. When using the default method,
Parties are required to use time series of equal length for all disturbance types considered. If including years after
the period 1990-2009 the Party should take care to ensure that this does not cause inconsistencies related topolicy assumptions (prior to December 2009) applied in the construction of the FMRL (see Section 2.7.5).
For rare events (such as volcanic eruptions), the emissions in all the years in the calibration period may be zero,
if the rare event has not occurred in that period. For other disturbance types, the Party needs to provide reliable
and transparent emission estimates for the years in the calibration period. Parties may enter zero for years inwhich the disturbance type does not exceed a low level that is implicit in their national statistics (e.g. for a year
when some trees may have fallen due to wind but when no wind-blow was registered at a stand level). It is goodpractice to sum for each year of the calibration period, separately for FM and AR, the emissions from all
disturbances types considered, in order to obtain a combined disturbance time series for the calibration period. It
is good practice to transparently report the combined time series (one for FM and one for AR) together with themethodology used to construct the time series. Finally, area-specific emissions are calculated for use in
subsequent calculations, especially in the case of AR, for which the area may considerably vary.

Chapter 2: Methods for estimation, measurement, monitoring and reporting

If emission estimates are missing for one or more years of the calibration period for a certain disturbance type, todevelop a complete and consistent time-series it is good practice to apply an appropriate method for filling thegaps selected from among those described in Chapter 5 in Volume 1 of the 2006 IPCC Guidelines. Surrogate
data is the method most likely to be applicable. Interpolation will probably not be appropriate due to thelikelihood of large year-to-year fluctuations in disturbance related emissions.
Emissions from and associated with salvage logging cannot be excluded from accounting during thecommitment period50. Consequently historical emissions from natural disturbances should exclude emissions
from salvage logging. It is therefore good practice that Parties provide transparent information on how thisexclusion was carried out.
If the required historic time series of emissions associated with natural disturbances cannot be directly estimatedfor a particular disturbance type, country-specific methods can be applied to develop a time series. For example,
if a Party lacks estimates of emissions from natural disturbances on AR land, it may choose to use disturbanceand area-specific emissions from natural disturbances on FM land as a proxy, and then combine it with the total
area of AR land in order to estimate the emissions from natural disturbances on AR land. The use of the proxymust be justified. For instance, in this example, it should be demonstrated for each disturbance type that theapplied area-specific emission rates on FM land are age-independent, or can be corrected for age, and areotherwise independent from the differences in species, size, density, management practices, etc. that may occur
between the forests on AR land and those on FM land. Correction for age class may be achieved by stratifying
FM data accordingly.
In the 2015 NIR and in subsequent years where recalculations leading to technical corrections occur, it is goodpractice to transparently report how the Party has estimated the emission data used in Table 2.3.1 and Table
2.3.2, including information on the methods used to estimate missing emission estimates in the time series.
S tep 3: D eve lop t he bac kg roun d le ve l
Once the time series for the calibration period have been developed by disturbance type, and summed over thetypes by year, the Party can apply the default or an alternative method (see description below) in order to obtain
the background level and the margin. Whatever method a Party chooses to establish the background level andmargin, it is good practice to transparently describe the method and assumptions used and to demonstrateconsistency with the FMRL or the methods and assumptions the Party applies for estimating emissions from AR.
While the steps below are described for Table 2.3.1, they equally apply to Table 2.3.2 with the exception that, inthe latter case, area-specific data are used (due to the probable large area change over time). The area-specificbackground level resulting from the procedure in this step must be multiplied by the average annual area of AR
estimated for the commitment period. FM should also be corrected for area if there is significant change in thearea of FM over the commitment period or significant change in the area is expected between the calibration andthe commitment period.
The default method
The default method involves the application of the following steps:(1) Calculate the arithmetic mean of the (area-specific, if necessary, cf. Box 2.3.8.) annual emissions summed
over disturbance types (in the ‘sum’ or bottom row, respectively, of Table 2.3.1 or 2.3.2) using all years in
the calibration period.
(2) Calculate the corresponding standard deviation (SD) of the annual emissions using the following formula:

such estimate(s) (‘outliers’) from the dataset and go back to step (1) above using the reduced dataset.
Emissions that are smaller than the mean minus twice the SD should not be removed from the dataset as thiswould lead to the expectation of net credits.
When no further outliers can be identified, the arithmetic mean and twice the SD, as calculated in the last step of
the iterative process, define the background level and the margin, respectively.
An example of the application of the default method is found in Box 2.3.7, Example 1.
Alternative methods
Alternative methods are country-specific but should be based on a consistent time series of annual emissions forthe calibration period as outlined in Step 2 above.
Alternative methods may include the use of other methods to exclude outliers and/or different criteria to define
the background level than the average of the emissions (excluding outliers) used in the default method.
Examples include setting the background level to a value equal to the lowest historical emission in thecalibration time series; or to a value between the lowest emission and the average of the historical dataset(excluding outliers) or to zero. An example of an alternative method is described in Box 2.3.7, Example 2.
S tep 4: D eve lop t he mar g in
Depending on the method used to estimate the background level, a non-zero margin may be needed to avoid the
expectation of net credits or net debits during the commitment period (refer to Step 5). For the default method(included in Step 3 above), the margin is twice the SD of the calibration period emission time series excluding
outliers.
If the background level is defined in a different manner than the default method, then the margin may bedifferent; e.g. if the background level is set equal to zero, or to the minimum emission value associated withnatural disturbance during the calibration period (see example in Box 2.3.7), then the margin is zero, since all
emissions in excess of the minimum level will be beyond the level assumed in the background level. Box 2.3.6
provides guidance on setting a margin that is consistent with an approach that avoids the expectation of net
credits and net debits.
For the development of the margin for AR, the margin to be associated with the area-specific background levelmust first be developed; then, as with the background level, it must be multiplied by the average annual area of
AR estimated for the commitment period. If the area of FM is expected to significantly vary, a similar correction
should be made, maintaining consistency with the background level.
S tep 5: Ensu r ing that th e me thod ap p lie d do es not lea d to t he ex pe ctat io n of net

For any approach used to develop the background level and the margin, Parties need to report information on
how the expectation of net credits or net debits51 is avoided. To this end, it is good practice to analyse, using thelist of requirements in Box 2.3.6, under what conditions the application of the background level and margin may
yield net credits or net debits for the Party during the commitment period. If the expected conditions in the51

Chapter 2: Methods for estimation, measurement, monitoring and reporting

commitment period will lead to the expectation of net credits or net debits, it is good practice that Parties revise
the approach used in order to avoid this. The results of the analysis and any action taken should be included in
the NIR due in 2015, or in years when the background level and the margin are recalculated. If any of therequirements in bullet points (1) – (4) in Box 2.3.6 are violated, it is good practice that the Party applies atechnical correction to the FMRL and the background level as needed in order to ensure consistency between the
FMRL and accounting during the commitment period (see Section 2.7.6 for guidance on technical corrections).

BOX 2.3.6
AVOIDING THE EXPECTATION OF NET CREDITS OR NET DEBITS FOR THE APPLICATION OF THE NATURALDISTURBANCE PROVISION

For developing a background level and a margin52 each annual emission resulting from natural
disturbances in the calibration period is either less than or equal to the background level plus themargin (these annual emissions are referred to below as the background group), or it is greaterthan the background level plus the margin. The background group is used to calculate thebackground level.
Any approach (default or alternative) will avoid the expectation of net credits or net debits so longas:(1) There is no observed trend in natural disturbance emissions during the calibration period thatis not considered in the background level estimation, or expected during the commitment
period. This includes trends due to changing area under FM or AR.
(2) The background level of emissions for FM or AR, included in the FMRL or associated withAR, respectively, is equal to the average of the annual emissions from natural disturbances
during the calibration period which are in the background group.
(3) Any emission from natural disturbances during the commitment period that falls into thebackground group is not separately excluded from accounting. During the commitment period,
emissions are only excluded from accounting when the annual emissions are greater than the
background level plus the margin. When this occurs, only those emissions that are greater thanthe background level are excluded.
(4) A test application of the constructed background level and the margin to the annual emissions
in the calibration period leads to the same background group as used during the constructionof the background level.

For FM, if all of bullet points (1)-(4) in Box 2.3.6 above are satisfied, and if the Party wishes to exclude
emissions from natural disturbances, the accounting outcome for natural disturbance emissions will result in:(1) Natural disturbance emissions which are greater than the background level are excluded fromaccounting in years where natural disturbance emissions are greater than the background level plus
margin;(2) The remaining emissions due to natural disturbances during the commitment period are included inaccounting during the commitment period. These natural disturbance emissions are effectively
balanced by the background level emissions from the natural disturbances that are included in the
FMRL. The expected outcome is that the background level emissions will be equal to the averagenatural disturbance emissions over the commitment period that are not excluded from accounting
individually.
As stated in Step 3 above, the background level and the margin need to be adjusted if the area of the land in the
AR or FM categories is expected to change during the commitment period. A possible way to do such an
adjustment is demonstrated in Box 2.3.8. In such cases, it is good practice to calculate the background level andthe margin so that they both relate to the expected area during the commitment period. In most, if not all,countries the area of AR changes considerably in the calibration period and will continue to change during thecommitment period (e.g. for AR, it increases from 0 in 1990 up to the actual value in an inventory year), so thecalculation should be done on a per unit area basis; the last two rows in Table 2.3.2 are meant to provide for AR
information related to the area and emissions per unit area.

A margin of zero is the same as the margin not being needed in terms of the language used in Decision 2/CMP.7.

EXAMPLES OF APPROACHES FOR THE DEVELOPMENT OF THE BACKGROUND LEVEL

Example 1. Application of the default method
In this example, Party X uses Table 2.3.1 to calculate the total annual emissions from the natural
disturbance types considered for FM lands for each year of the calibration period in row Sum.
These total annual emission values are shown in Figure a) (all bars). Based on the iterative processdescribed in Step 3 above, the outliers in the time series (the dark bars in Figure a)) are identified
and removed. The background level is estimated as the mean (the thick black horizontal line in
Figure b)) of the remaining emissions (the hashed bars). The margin is twice the standard deviationof these remaining emissions (shown by a thin black line above the background level in Figure b)).
In a year during the commitment period for which the total emissions from natural disturbances(e.g. the dark bar for the year 2016 in Figure b)) exceeds the background level plus the margin, theemissions above the background level (the thick dashed line) may be excluded, provided that all of
the other requirements for the application of the natural disturbance provision are met. The
emissions that may be excluded are shown as the dotted part (EE) in Figure b). Note that annual
emissions from zero to the background level plus the margin, but not higher than this, are also
factored out by the accounting, since they are included in the FMRL. In order to avoid the
expectation of net credits or net debits, the expected emissions from natural disturbances includedin the FMRL need to be equal to the background level.

2.51

Chapter 2: Methods for estimation, measurement, monitoring and reporting

Example 2. An alternative method: the background level is set to the minimum level of ahistorical time series
A possible alternative approach is to set the background level to a value equal to the minimum
emission value of the historical time series (i.e. the emissions for year 2001 in Figure a)). In thiscase, the emissions are expected to exceed this level in every year during the commitment period,
and the margin is set equal to zero. In a year during the commitment period for which theemissions from natural disturbances (e.g. the dark bar for the year 2016 in Figure c)) exceed thebackground level (since the margin is equal to zero), the emissions above the background level(the thick dashed line) may be excluded, provided that all of the other requirements for theapplication of the natural disturbance provision are met. The emissions that may be excluded areshown as the dotted part (EE) in Figure c). Note that the emissions from zero to the backgroundlevel (which are represented by the emissions that are below the dashed line in the last bar in
Figure c)) are also factored out by the accounting, since they are already included in the FMRL.

EXAMPLE OF AN APPROACH FOR ESTIMATING THE BACKGROUND LEVEL IN CASE THE AREA OF LAND UNDER
FM AND / OR AR CHANGES BETWEEN THE CALIBRATION PERIOD AND THE COMMITMENT PERIODThis approach is demonstrated using an example when the area of AR changes during thecommitment period. It would also apply to cases where the area of FM significantly changes, inwhich case the modifications for FM are necessary.
Suppose the area of AR at the end of the calibration period is Acal, and the area specificbackground level from Table 2.3.2 is bgl. The background level based on Acal is therefore BGLcal,= bgl * Acal . Suppose that the mean area of AR land during the commitment period is expected to
be Acomm and assume that bgl will not change, thus, the background level should be
BGLcomm = Acomm * bgl. Without adjustment, using BGLcal would lead to net credits (in caseAcomm < Acal) or net debits (in case Acomm > Acal). In order to avoid these situations, it is goodpractice to conduct the following steps:(1) Calculate the area-specific annual emissions for the calibration period using the totals of all
disturbance types (last row of Table 2.3.2 (for FM, Table 2.3.1)).
(2) Use these area-specific annual emissions to calculate the area specific background level bgl for
AR using the stepwise guidance for developing the background level and margin.
(3) Make a projection, i.e. an unbiased estimate of the annual increase, of the area under AR forthe commitment period. (For FM, this projected area should be consistent with the area projectedunder the FMRL.)(4) Calculate Acomm, the average of the projected area under AR (or FM, respectively) provided instep (3) above.
(5) Calculate the background level for the commitment period as BGLcomm = Acomm * bgl.

2.3.9.7

E XCLUSION OF REMOVALS ON LANDS AFFECTED BY THE
NATURAL DISTURBANCE PROVISION

In cases in which a Party excludes emissions from natural disturbances from accounting in accordance with theprovisions detailed in paragraphs 33 through 36 of Annex to Decision 2/CMP.7, it should also exclude any
subsequent removals during the commitment period on the affected land from accounting. Therefore it is goodpractice that the Party assess and report the removals (using the guidance given above in Section 2.3.9.3) that
occur on lands affected by the disturbance(s) for which emissions were excluded from the accounting, regardlessof whether they originate from the re-establishment of young forest vegetation by rehabilitation measures orfrom the natural re-growth of vegetation, and to ensure their subsequent exclusion from accounting. Special careneeds to be taken to ensure that the removals are not captured by another assessment system, if for example
complementary assessments on the natural disturbance areas are conducted in addition to a national forest
inventory; or that the national forest inventory is designed in a way that can provide separate outputs for theseareas. It is good practice for Parties using a projected FMRL to provide information on how the estimation ofemissions and removals following natural disturbances has been matched to the treatment of emissions andremovals in the construction of the FMRL, in order to avoid double counting. For example, the FMRL may
contain a certain amount of emissions and removals associated with the disturbed area, but originating from FM
activities, in case the area would not have been disturbed.

2.3.9.8

I NFORMATION ON EFFORT S TAKEN TO REHABILIT ATE THE
LAND SUBJECT TO NATU RAL DISTURBANCES

Once a natural disturbance has occurred, the Party may implement actions to rehabilitate the land cover, wherepracticable, in order to restore or secure forest functions and prevent the further degradation of forests. Althoughrehabilitation is different from both restoration and revegetation in terms of GHG reporting, the techniques used
may include the same as used for reforestation and revegetation, e.g. planting, seeding and/or the human-induced
promotion of natural seed sources. The rehabilitation effort will depend on the severity of the impact, thelikelihood of regeneration and the cost-benefit analysis, taking site characteristics into account. Following, forexample, wind-throw, usable timber may be removed (salvage logging, see Section 2.3.9.3), the affected areas
are cleared by e.g. banking of debris (which affects DOM and soil organic matter pools) or preparation ofplanting sites in places, and subsequent planting of crop tree species or seed-bed preparation is conducted, if
seeds or seed trees are still available on the lands. If seed trees or natural regeneration are available (such as incases where the disturbance mainly affected higher age-classes and led to a shift in the age-class distribution),2013 Revised Supplementary Methods and Good Practice Guidance Arising from the Kyoto Protocol

2.53

Chapter 2: Methods for estimation, measurement, monitoring and reporting

rehabilitation can be restricted to activities that ensure the site is accessible for further management activities
following e.g. salvage logging. In case of forest fires, species within ecosystems can respond to fire and fire
regimes in different ways (Gill, 1975). For example, some forest species are resilient to even the most severe
fires and respond through epicormic resprouting post fire. In such instances, rehabilitation efforts may not be
required; in these cases, it is good practice to demonstrate that no other direct human intervention is necessary
for rehabilitation.
A Party applying the natural disturbance provisions shall provide transparent information that demonstrates
efforts taken to rehabilitate, where practicable, the land for which the provisions in paragraph 33 above areapplied (paragraph 34(e) of Annex to Decision 2/CMP.7). To demonstrate this, while allowing for the distinctionof rehabilitation and other management activities that might constitute land-use change and avoiding double
counting, it is good practice to provide transparent information on:-

Rehabilitated area, or are planned to be rehabilitated;-

Time frame for the rehabilitation, i.e. duration of the management activity undertaken if this is notcompleted in the year of reporting, or time until a specified state (‘result’, see below) is expected to bereached;-Description of the efforts taken and/or planned, including where no action is to be taken because theforest ecosystem rehabilitates without human intervention;-

Expected results, these may be e.g. the recovery of carbon stocks, forest cover, or tree species structureand growth patterns, as well as ecosystem health conditions and any changes in efforts to avoid further
disturbances.

If efforts have not been taken and/or are not planned to rehabilitate the areas subject to natural disturbances, it isgood practice to provide transparent information on the reasons why the rehabilitation is not intended and/or
impracticable. For example, natural regeneration in the disturbed area might make human intervention
unnecessary or a volcanic eruption may completely cover an area with lava. In cases where natural or humaninduced regeneration is not possible, and there is no land-use change, the area is still technically considered to be
FM (no human-induced deforestation occurred) and included in the reporting and accounting appropriately. If, in
the future, other uses are conducted in these areas, e.g. cattle is grazed on grass growing on the disturbed area,
this indicates a change in land-use and may have to be considered as Deforestation (see decision trees in Sections
1.3 and 2.6).

2.3.9.9

T REATMENT OF EMISSION S AND REMOVALS THAT OCCUR
ON THE LANDS SUBJ ECT TO NATURAL DISTU RBANCES INSUBSEQUENT COMMITMEN T PERIODS

Paragraph 36 of Annex to Decision 2/CMP.7 requires that the treatment of emissions and removals that occur on
the lands [subject to the disturbance provisions] in the subsequent commitment periods shall be reflected in landuse, land-use change and forestry accounting for those commitment periods. Therefore, it is good practice thatthese emissions and removals are estimated in a manner that is consistent with other forestry estimates in the
GHG inventory and integrated into estimates for future years, so that accounting in subsequent commitment
periods can reflect them.

OTHER GENERIC METHODOLOGICALISSUESThis section presents generic methodology to complement subsequent sections in the report as well as guidance
for time series development and recalculations. Issues related to uncertainty assessment, reporting anddocumentation are also addressed. Draft reporting tables are presented in the Annex to this report.

2.4.1

Developing a consistent time series

Lands subject to Article 3.3 or 3.4 activities and the management thereon need to be tracked through time, toensure that all GHG emissions and removals are reported throughout CPs and with no gap between periods.
Moreover, the continuity of management greatly influences GHG emissions and removals, and changes inmanagement or land use are often the periods associated with the greatest changes in carbon stocks. For example,
it is not sufficient merely to state that 10% of a CM area has been under no-till for a specified period. The rate ofcarbon stock change for the total area depends on whether the same 10% of land has remained under no-till orwhether the 10% of no-till occurred on a different portion of the area in different years. It is therefore goodpractice to track the management of land subject to Article 3.3, FM and elected 3.4 activities. (See also Box
2.4.1)
Assessment of the continuity of management on land could be achieved either by periodically tracking lands
subject to an Article 3.3, FM or an elected Article 3.4 activity from 1990 until the end of the CP (see Section
2.7.2 Choice of methods for identifying lands subject to Forest Management), or by developing statisticalsampling techniques that can determine the transition of different types of management on land subject to Article
3.3, FM or elected 3.4 activities (see 2006 IPCC Guidelines). An example of how such a scheme could operate isgiven in Box 2.4.1.
A supplementary condition for developing a consistent time series is to use the same methods for estimating
carbon stock change and non-CO2 GHG emissions during the whole period and for setting the benchmark value
to be used in accounting i.e. either the reference level or the base year value, or to ensure consistency between
different methods.
Time series consistency is discussed further in Chapter 5, Volume 1 (Time series consistency) of the 2006 IPCC
Guidelines.

Chapter 2: Methods for estimation, measurement, monitoring and reportingBOX 2.4.1
AN EXAMPLE OF CONSISTENCY IN ESTIMATING THE EFFECT OF MANAGEMENT PRACTICES

To estimate changes in soil carbon stocks, whether by Tier 1, 2 or 3 methods, management
practices on applicable lands need to be tracked over time. Ideally, the management of each land
would be tracked explicitly. But such data may not always be available. An alternative approach
may be to estimate the average history of lands and soil now under a given management. Consider
the following example.
Example: Cropland management
Suppose there was a cropland region of 10,000 ha, of which 5,000 are in no-till (NT) in the year
2000, up from 2,000 ha in 1990. The remainder, in each year, is under conventional tillage (CT). It
is assumed no tracking of the management on individual land. In order to simplify this example,
suppose further that the land management in the year 1990 was unchanged for more than 20 years.
The estimated soil carbon stock change is based on a matrix of coefficients; say 0.3 tonnes C/ha/yr
for land shifting from CT to NT, and -0.3 tonnes C/ha/yr for a shift from NT to CT. (The carbon
stock change is calculated by the amount of soil carbon, the relative carbon stock change53 factor,
over 20 years, for the management activity, and the length of the period, one year. See Chapter
5.2.3, and Tables 2.3 and 5.5, Volume 4 of the 2006 IPCC Guidelines.) There has been no trackingof management on individual land. Based on a statistical analysis (e.g. a survey), it is possible toestimate, with confidence, the following shifts:
CT



NT

3,500 ha

CT



CT

4,500 ha

NT



CT

500 haNTNT

1,500 haThe total carbon gain is therefore:(3,500 • 0.3 + 4,500 • 0 + 500 • (-0.3) + 1,500 • 0) tonnes C/yr = 900 tonnes C/yr.

53“Carbon stock change factor” is in use to refer to carbon emission/removal factors.

2.4.2

Recalculation of time seriesThis section deals with recalculation of time series, excluding implications for the technical correction ofreference levels; which is addressed in Section 2.7.6. As inventory capacity and data availability improve, themethods and data used to calculate estimates are updated and refined. Recalculation of historic emissions andremovals is good practice when new methods are introduced or existing ones refined, when new sources andsinks categories are included, or when data are updated (for example through new measurements during the CPor the availability of new information on verification). Recalculations may also be needed if lands arereclassified at a later time (e.g. for lands that have lost forest cover but where a classification as deforested lands
was pending and has been resolved, see Section 2.6.1).
The CMP decisions make provisions for recalculation54, consistent with the UNFCCC reporting guidelines, andmention that previous estimates should be recalculated using the new methods for all years in the time series.
Annual GHG emissions and removals reported for a given year during the CP can be recalculated in subsequent
reporting years (up to the final year of the CP). When recalculating emissions and/or removals, time seriesconsistency must be checked and ensured. It is also good practice to report why the new estimates are regarded
as more accurate or less uncertain.
One potential problem in recalculating previous estimates is that certain data sets may not be available for theearlier years. There are several ways of overcoming this limitation and they are explained in detail in Chapter 5,
Volume 1, of the 2006 IPCC Guidelines.

2.4.3

Uncertainty assessment

It is good practice that uncertainties are identified, quantified and reduced as far as is practicable and that all
information on anthropogenic GHG emissions by sources and removals by sinks which result from mandatory
and elective activities are reported with levels of confidence as elaborated by any IPCC good practice guidance
adopted by the CMP.55 Because of the importance for many countries of well-designed sampling programmes toreduce uncertainties when preparing LULUCF inventories, specific information on the design of sampling
programmes for land areas and biomass stock, as well as the assessment of associated uncertainties should be
provided. Generally, the approaches provided in Chapter 3, Volume 4 of the 2006 IPCC Guidelines and theestimation of sampling error related to the sampling design used for data collection can be used for assessing
uncertainties associated with estimates reported under the UNFCCC and under the KP LULUCF activities (IPCC
2010c). However, some issues and terms which are specific to the KP require additional uncertainty assessment,
for example the estimation of the areas under KP LULUCF activities or the need to track activities since 1990.
For KP reporting, uncertainty assessment is particularly important in order to support verification requirements.
Moreover, while selecting a particular tier to estimate changes in carbon stocks and non-CO2 GHG emissions, it
is good practice to consider the implications of this choice for the management of uncertainties

2.4.3.1

I DENTIFYING UNCERTAINTIESIn the context of KP reporting in the LULUCF Sector, the following sources of uncertainties are likely to besignificant:

Definitional errors, such as bias and inconsistencies resulting from the interpretation and implementation of
the various definitions in the KP (including the potential mismatch between data available to Parties andtheir interpretation of the definitions).

Classification errors, such as land-use and land-transition classification errors (e.g. forest vs. non-forestclassification with possible errors regarding temporarily unstocked forest lands).



Activity data errors (e.g. distinction between the harvest-regeneration cycle vs. deforestation or humaninducement of afforestation and reforestation).



Identification errors arising while defining the geographical boundaries of areas encompassing lands subject
to KP LULUCF activities54

See paragraphs 4, 12 (notably 12(d) and 12(e)), 13 and 14(e) in Annex to Decision 19/CMP.1 (Article 5.1), contained in
document FCCC/KP/CMP/2005/8/Add.3.

(2003). Sampling errors can increase when samples do not sufficiently cover the temporal and spatial
variability of the estimated parameter. This is particularly critical when reporting land areas that include
multiple land units by using legal, administrative, or ecosystem boundaries.

to identify lands subject to the various activities, e.g. AR vs. D, or modifications made to the sampling
procedures and/or densities over time or due to positional errors).



Model errors occur whenever models or allometric equations are used to estimate carbon stock changes or
non-CO2 GHG emissions and removals, which is likely to be the case at higher tiers. It can be very
cumbersome to trace the propagation of errors through complex models chained to each other. In general,
this may introduce additional uncertainties. In some cases simpler models can be used to estimate typicaluncertainty ranges that can be combined with central estimates from complex models.

Natural varia bility
Natural variability is a result of variations in natural controlling variables, such as annual climate variability, andvariability within lands that are assumed to be homogenous, e.g. the spatial variability of forest soils within agiven land. When sufficient experimental data are available, good practice should permit determination of theresulting combined plot-level and up-scaling uncertainties using standard statistical methods such as Generalized
Linear Models (e.g. Tate et al., 2003). In some cases, especially for interannual or periodical variability, largescale disturbance impacts may change the sign of the reported net emissions and removals of an entire country or
region. In inventory calculations uncertainty due to natural variability can be reduced by using time-averaged
coefficients and by averaging direct measurements over a time period that is long enough to reduce thevariability, as discussed in Section 2.3.5 (Interannual variability).

Activity data
In addition to uncertainties in default carbon emission and removal factors, there are often uncertainties
associated with missing or inaccurate activity data. Determining retrospectively the inventory for the base year,
in most cases 1990, may pose a particular challenge for CM, GM, RV and WDR. It may be possible to establishbase year emissions by extrapolating a consistent time series of emissions and removals established for a period
over which activity data are available. Alternatively a country-specific methodology may be used if this can beshown to be more reliable in estimating base year carbon stock change. It is good practice to verify that thismethodology does not over- or underestimate emissions/removals in the base year (see Section 2.4.6). It is also
good practice to use in the estimation of base year emissions historical data on management practices prior to
1990, if available.

Spatial resolution of remote sensing and ground truth
The objective of using satellite imagery for land-cover and land-use assessments is to obtain, for an inventory
region, total area estimates, percentages of land classes, or geographical boundaries. Remote sensing isparticularly well suited to completely identify lands. A source of uncertainty is the selection of imagery of
inadequate resolution. In order to capture changes in areas as small as one hectare, the resolution of the imagery
must be finer than one hectare. In addition, improper or insufficient ground truthing can result in classification
errors.
Positional errors occur where (a) the geometric correction is not done, incomplete or false, (b) the pixel locationand location of the ground truth plot do not coincide, and (c) there is insufficient accuracy in the definition of theborderlines. For example, when detecting land-use changes by a time series of remotely sensed images, thespatial displacement of pixels from one sampled image to the next will introduce errors. In the case of detectionof a transition from forest to non-forest or vice versa, the associated uncertainties will be larger when forests are
fragmented.
Classification errors arise from an incorrect identification of the real land cover class. They comprise omission
errors, i.e. a population element from a given category is omitted and put erroneously into another class, andcommission errors, i.e. classifying wrong categories into a given ground truth category.
The use of remote sensing is discussed further in Chapter 3, Volume 4 of the 2006 IPCC Guidelines, especiallysection 3A.2.4. An example of quantifying uncertainties in forest carbon estimation using a combination of
remote sensing and field measurement is given by Gonzalez et al. (2010).

2.4.3.2

Q UANTIFYING UNCERTAINTIES

Uncertainties associated with carbon stock changes and emissions estimation are to be quantified according tostandard statistical methods. Uncertainties can originate from several sources and be combined into an overall
uncertainty.
It is good practice to derive confidence intervals by applying a quantitative method to existing data.
Uncertainties for the KP activities can be treated in the same way as other uncertainty estimates taking into
account that:The “since 1990” clause and the use of definitions specific to the KP are likely to cause systematic errors
related to the estimation of the required activity data. The potential for differences between the managed
forest area and the area subject to FM (see figure 2.7.1), and also between Grassland area and area subject to
GM implies that the areas for which uncertainties are being assessed may differ between the KP activities
and the corresponding categories of the 2006 IPCC Guidelines.



Activity data can also relate to individual practices or ownership structures, e.g. the fraction of cropland on
which farmers use a given amendment or practice. If the fraction is estimated by survey, the survey design
should incorporate an uncertainty estimate depending on the level of inventory data disaggregation,otherwise the uncertainty will have to come from expert judgement.



For CM, GM, WDR and/or RV (if elected) uncertainty estimates are also needed for the base year. It is goodpractice that the selected methodology neither over- nor underestimate emissions and removals in the baseyear. But uncertainties are likely to be higher than for estimates in the CP, because the estimates for the baseyear may often be derived only by backward extrapolations or models, rather than by actual inventories in ornear the base year. In addition, determination of activities in the base year, where required, may posedifficulties if pre-base year surveys of land use are not available. Where reliable data are not available for1970 to 1990 (or other applicable time periods), countries can use a country-specific methodology, shown tobe reliable, to estimate base year carbon stock change in 1990. In most cases, these methods also require
historical data on management practices prior to 1990. The associated uncertainties could, in principle, be
assessed by formal statistical methods, but more likely by expert judgement which is based on the feasible
ranges of backward extrapolation of time trends. If surrogate data (i.e. alternative data sets that can be used
as a proxy for missing data) are available, they can be a useful guide for extrapolating the trend in periodic
data and subsequently interpolating the same data following the next data collection cycle. If there are noavailable surrogates or other information, then the only technique available is to extrapolate, with arecalculated interpolation of the estimates when the new observations are available. Thus, it is good practice
to attempt to find reliable surrogate data to guide extrapolation and interpolation when the fundamental data
used for the inventory estimates are not available for the base year.

When remote sensing is used for classification of land use and detection of land-use change, theuncertainties could be quantified by verifying classified lands with adequate actual ground truth data or
higher spatial and temporal resolution imagery. Details of this methodology can be found in McRoberts et al.
(2010). In order to estimate the accuracy of land-use/land-cover maps on a category-by-category basis, anumber of sample points on the map and their corresponding real world categories are used to create an error
matrix (Lillesand et al., 2008, McRoberts and Walters, 2012). The diagonal of this matrix shows theprobability of correct identification and the off-diagonal elements show the probability of misclassificationof a land category into one of the other possible categories. The error matrix expresses not only the accuracyof the map but it is also possible to determine which categories are easily confounded with each other. Basedon the error matrix, a number of accuracy indices can be derived (Congalton and Green, 2009). It is goodpractice to present an estimate of the accuracy of the land-use/land-cover map category-by-category and anerror matrix may be employed for this purpose where remote sensing is used. Multi-temporal analysis(analysis of images taken at different times to determine the stability of land-use classification) can also be
used to improve classification accuracy, particularly in cases where ground truth data are limited. A review
of methodologies for monitoring ecosystem is presented by Coppin et al. (2004). Methodology for
estimating uncertainties in area estimation is also presented by Olofsson et al. (2013).

Separate annual uncertainty estimates need to be made for each of the mandatory and elective activities, for eachreported carbon pool each GHG and each reporting subdivision selected by the country. Estimates can bereported using tables generated following the model of Tables 1A-11B in Annex 2A.1 to this report. Separate
tables are required for the base year if CM, GM, RV or WDR are elected. Estimates can be expressed as percentof the area and of emissions by sources or removals by sinks (or changes in stocks) reported in Tables 1A-11B.
Uncertainty associated with areas of lands need to be estimated. When using Reporting Method 1, it is goodpractice to report a separate estimate of uncertainty for each of the mandatory activities, and each of the elected2013 Revised Supplementary Methods and Good Practice Guidance Arising from the Kyoto Protocol

2.59

Chapter 2: Methods for estimation, measurement, monitoring and reporting

activities within a given geographical boundary. Under Reporting Method 2, each geographical boundary is
subject to a single activity. Therefore there will only be one uncertainty estimate needed for each geographicalboundary. However, because Reporting Method 2 can contain very large numbers of polygons it is sufficient toprovide uncertainty estimates for the summary statistics and for the reporting strata selected by the country.
Where uncertainties are difficult to derive, it is good practice to use default values for uncertainties. Guidance on
selecting default carbon emission or removal factors for CM can be found in Annex 4A.1 of the GPG-LULUCF,
Tool for Estimation of Changes in Soil Carbon Stocks associated with Management Changes in Croplands andGrazing Lands based on IPCC Default Data. Since these factors are taken from the IPCC Guidelines, no true
uncertainty ranges can be assigned. However, using expert judgement, default uncertainty ranges corresponding
to a sampling error of 50% can be assigned, based on an analysis of no-till long-term experiments in Europe inwhich the 95% confidence interval of the mean annual emission or removal estimate was found to be around ±50%of that mean (Smith et al., 1998). For RV and WDR, default uncertainty ranges cannot be specified at present. It
is good practice for a country electing these activities to provide its own estimates of the uncertainty associatedwith emissions and removals from all pools for the affected lands. Estimates of uncertainties have to be based onnational sources or expert judgment reflecting national circumstances. Inventory compilers may also apply
national methods for estimating the overall uncertainty, e.g. error propagation methods that avoid the simplifying
approximations and in this case, it is good practice clearly to document such methods.
Problems may arise when activity data are lacking or are not well-documented. Activity data necessary to apply
scaling factors (i.e. data on agricultural practices and organic amendments) may not be available in current
databases/statistics. Estimates of the fraction of farmers using a particular practice or amendment should then be
based on expert judgement, and so should the range in the estimated fraction. As a default value for theuncertainty in the fraction estimate, ±0.2 is proposed (e.g. the fraction of farmers using organic amendment
estimated at 0.4, the uncertainty range being 0.2–0.6). As practical consideration it is assumed that uncertainties
of the various input data estimates, either as default values, expert judgement or estimates based on soundstatistical sampling can be combined for an overall uncertainty estimates.

2.4.3.3

R EDUCING UNCERTAINTIES

Estimating uncertainties in a quantitative manner helps to identify major sources of uncertainties and to pin-point
areas of potential improvements to reduce uncertainties in future assessments. In particular, for reporting under
the KP it is recommended to make efforts to convey the overall uncertainty estimates to all agencies and/or firms
involved in order to encourage improvement, i.e. reduced uncertainties in estimates of future reports. It is also
good practice to establish institutional means and procedures that are likely to contribute towards reducing
uncertainties. For instance, a country may choose on purpose to estimate uncertainties by more than one
procedure. This will produce complementary results for the same country and data category, prompting further
research on potential sources of inconsistency and ultimately enhancing the robustness of estimates.
Often, uncertainties can be reduced if areas subject to land-use change are estimated directly as a class bythemselves within a stratification scheme, rather than as a difference between two overall estimates of land-use
areas. The extra effort required for area identification should help to reduce uncertainties in the assessment ofareas subject to KP activities.
Uncertainties are likely to be reduced by implementing means to make the design, procedure and frequency ofdata collection more systematic, for example by establishing – whenever possible – long-term, statistically soundmonitoring programmes.

It is good practice to use coordinates as set out in Sections 2.5 to 2.12 below for the reporting of thegeographical location of the boundaries that encompass the lands subject to activities under Article 3.3, FM andelected activities under Article 3.4. This information can be summarised on a digital map for visual presentationand data sharing. It is also good practice to report the land transition matrix (Table 2A) to demonstrate that thecountry has accounted for all areas where AR, D and FM and, if elected, any Article 3.4 activities have occurred.
The diagonal cells of the table indicate the area of lands remaining in the same category (e.g. FM land remaining
FM land), while other cells indicate the areas of lands converted to other categories (e.g. CM land converted toafforested land). It is good practice that the total area reported in consecutive inventories is constant and that any
change in the total area is documented and explained.
For Article 3.3 and 3.4 activities (Tables 4A to 7), data should be provided by geographical locations (See
Section 2.2.2: Reporting Methods for Lands subject to Article 3.3 and Article 3.4 activities). Activity data may
be further subdivided according to climate zone, management system, soil type, vegetation type, tree species,
ecological zone, national land classification or other criteria; in such a case, for each subdivision, one row should
be completed in the table. The CMP decisions also require that, in addition to the data for the actual inventory
year and any previous year of the CP, a Party also reports this information for the base year for CM, GM, RV
and WDR. No reporting is necessary for those Article 3.4 activities that were not elected by the Party.
When filling in these tables, care should be taken to insert carbon stock changes for each pool with proper signs.
Carbon stock changes are to be reported in units of carbon as positive when the carbon stock has increased, andas negative when the carbon stock has decreased. All changes are totalled for each geographic location, and thetotal values are then multiplied by 44/12 to convert carbon stock changes to CO2 emissions or removals. This
conversion also involves sign change to switch from the ecosystem to the atmospheric perspective: stockchanges refer to ecosystem carbon stocks (where decreases have a negative sign) while fluxes of CO2 and nonCO2 GHGs refer to exchanges with the atmosphere where emissions are additions to the atmosphere andtherefore have a positive sign.

Table 1A (in the annex of this supplement) is a summary table of carbon stock changes resulting from activities
under Articles 3.3 and 3.4 for the inventory year. It is good practice to also use the table for the base year foreach elected Article 3.4 activity. This table summarises data of the compilation tables by activity across all
carbon pools and non-CO2 GHG emissions and across all strata within a country.
In addition to the data in the Tables, it is good practice to report the underlying assumptions and factors used forthe calculation of the carbon stock changes and emissions of CH4 and N2O, as well as for the calculation of theuncertainties.
Decision 2/CMP.7 contains a clause for AR and FM activities that carbon stock changes and non-CO2 GHG
emissions resulting from natural disturbances may be excluded from accounting (see Tables 4B, 4C, 4D, 6D, 6E,
6F and Table 5B). If this provision is used then the areas where such disturbances occurred have to be identified
and monitored for subsequent land-use change.57 If such lands exist for the inventory year, it is good practice todistinguish them from other AR and/or FM lands and to report them (and the associated carbon stock changes
and non-CO2 GHG emissions, distinguishing emissions from subsequent removals) separately in Tables 4A to
6A. Although this is an issue related to accounting, it is mentioned here because inventory data are likely to beneeded to implement the ND provision.
Decision 2/CMP.7 contains a clause that Parties can elect to report carbon stock changes and non-CO2 GHG
emissions resulting from conversion of forest plantation to non-forest land under FM together with carbon stockchanges and non-CO2 GHG emissions resulting from conversion of at least an equivalent area of non-forest land
converted to forest land (CEFC, see Table 6C). If this CEFC provision is used, then all areas subject to thisprovision have to be identified and their georeferenced locations reported58 in Table 6A. Although this is an
issue related to accounting, it is mentioned here because inventory data are likely to be needed to implement theprovision.
Separate tables should be reported for the base year when CM, GM, RV and/or WDR are elected.
Finally, separate annual uncertainty estimates should be reported for each activity under Articles 3.3 and 3.4, foreach reported carbon pool, each GHG and geographical location. Uncertainty estimates are to be made at the 95%
confidence limits expressed as percent of the emissions by sources or removals by sinks (or changes in stocks).

R EPORTING N ON -CO 2 GHG EMISSIONS AND CO 2
EMISSIONS FROM LIMIN G AND UREA APPLICATI ON

Reporting of emissions of non-CO2 GHG emissions and CO2 emissions from liming and urea application fromlands subject to AR, D, FM, CM, GM, RV and WDR requires assigning emissions among the Agriculture Sector
and the relevant KP LULUCF activity consistently with the UNFCCC reporting guidelines for national GHG
inventories59, whilst avoiding double-counting.
For lands under CM, GM, RV, WDR, D and FM60 activities, which are under Cropland and managed Grassland
use in the Convention reporting, the following N2O and CH4 emissions are reported under Agriculture61:
Direct N2O emissions due to(i)

Use of inorganic N (synthetic) fertilisers;(ii)

Use of organic N fertilisers (e.g. animal manure, sewage sludge);Direct and indirect N2O emissions from N mineralisation associated with loss of soil organic matter resulting
from change of land-use and management of mineral soils.

Indirect N2O emissions from nitrogen used in agriculture:

According to Decision 16/CMP.1 estimates of emissions from sources and removals by sinks from Article 3.3 and 3.4
activities are to be clearly distinguished from anthropogenic emissions from the sources listed in Annex A to the Kyoto
Protocol (cf. paragraph 5 in Annex to Decision 16/CMP.1 (Article 7), contained in document FCCC/CP/2001/13/Add.3,p.22).

Emissions from the following practices are also reported under Agriculture, irrespective of land-use:CO2 emissions from liming; andCO2 emissions from urea application.

For lands under FM and AR, the direct N2O emissions from N fertilisation (from either synthetic or organic N
fertilisers) and the related indirect N2O emissions can be reported under these KP LULUCF activities, whendisaggregated data on N fertilisation by land-use category are available. Otherwise, these emissions are to bereported under Agriculture. Care should be taken that these emissions are not double-counted. Methods for
estimating these emissions from N fertilisation are described in Section 11.2 of Chapter 11, Volume 4 of the2006 IPCC Guidelines.
For lands under FM64 and AR, all emissions from fires, including fires from organic soils and N2O and CH4
emissions from drainage and rewetting of organic soils are to be included under these activities.

2.4.4.3

D OCUMENTATION

Documentation requirements under the KP are outlined in the relevant decisions of UNFCCC as part of thedescription of the requirements for inventory management65. The information required includes all disaggregatedemission factors, activity data, and documentation about how these factors and data have been generated andaggregated for the preparation of the inventory.
It is good practice to document and archive the underlying data and description of, or reference to, methods,
assumptions and parameters used to produce estimates of GHG emissions and removals that would allow
independent reviewers to follow the process of developing the reported estimates. Documented data andexplanation of methods, and the rational for their selection should be provided for both steps: the identificationof land and the assessment of carbon stock changes and the emissions of non-CO2 GHGs.
Documentation should also include information about uncertainty assessment (see also Section 2.4.3 Uncertainty
Assessment), QA/QC procedures, external and internal reviews, verification activities and key category
identification and planned improvements (see Volume 1 of 2006 IPCC Guidelines, General Guidance andReporting).

ACTIVITIES DEFINITION AND IDENTIFICATION
It is good practice to explain how the definitions of FM and of the elected Article 3.4 activities have beeninterpreted according to national circumstances. For instance, if only a part of the managed forests reported in
the UNFCCC GHG inventory is excluded from FM in KP reporting, the criteria that are used to distinguishforests under FM from managed forests should be provided. It is also good practice to document differences
between the definitions for Croplands (or Grasslands) in the UNFCCC GHG inventory and lands subject to CM(or GM).

DATA DOCUMENTATION
When using Reporting Method 1, the areas encompassed by the geographical boundaries resulting from thestratification of a country, should be identified by unique serial numbers in the tables. These serial numbers are

to be cross-referenced to a database or other archive (the LULUCF Archive) specifying the locations in terms ofestablished legal or administrative boundaries, or by means of an existing coordinate system, for example anestablished national grid system, the UTM (Universal Transverse Mercator) grid or latitude and longitude. Whenusing Reporting Method 2, land-area identification should be possible through the databases associated with theuse of this reporting method.
It is good practice to ensure that the documentation of estimates of GHG emissions and removals include:The sources of all data used in the calculations (i.e. complete citations for the statistical database(s) fromwhich data were collected);

The information, rationale and assumptions that were used to develop reported data and results, in cases they
were not directly available from databases (for instance if interpolation or extrapolation methods have been
applied) and a comparison to other published emission factors and explanation of any significant differences

The frequency of data collection; and

Estimates of the associated uncertainties with a description of the major sources of the uncertainties.

DESCRIPTION OF THE M ETHODS USED IN LAND IDENTIFICATION AND
ESTIMATION OF EMISSI ONS AND REMOVALS
It is good practice to document the methods with the following information:


Choice of Reporting Methods for lands subject to Articles 3.3, FM and 3.4 (Reporting Method 1 or 2) or adescription of the Reporting Method, if a combination of the two is used;

Description of the approach used for geographical location and identification of the geographical boundaries,
lands; references of maps used, if any;

Choice of Tier(s) used for estimating GHG emissions and removals;

Methods used for estimating carbon stock changes, non-CO2 GHG emissions and magnitudes of thecorresponding uncertainties;



If Tier 1 is used: all values of default parameters and emission/removal factors used;

If Tier 2 is used: all values and references of default and national parameters and emission/removal factors
used;



If Tier 3 is used: Parties should, as applicable, report information on: basis and type of model, application
and adaptation of the model, main equations/processes, key assumptions, domain of application, how themodel parameters were estimated, description of key inputs and outputs, details of calibration and model
evaluation, uncertainty and sensitivity analysis, QA/QC procedures adopted and references to peer-reviewed
literature, description of the process by which carbon stock changes and emissions or removals are
estimated;In case of Tier 2 or 3 the documentation should justify the use of specific parameters, factors or models;Transparent and verifiable information that demonstrates that the pools not included in the reporting are notsources.

ANALYSIS OF INTERANN UAL VARIABILITY
It is good practice to explain significant interannual variability in reported emissions or removals. The reasonsfor any changes in activity levels and in parameter values from year to year should be documented. If the reason
for the changes is an improvement in methods, it is good practice to recalculate results for the preceding years
by using the new methods, new activity and/or new parameter values (see Chapter 5, Volume 1 of the 2006
IPCC Guidelines ‘Time series consistency’)2013 Revised Supplementary Methods and Good Practice Guidance Arising from the Kyoto Protocol

2.4.5

Quality Assurance and Quality Control

It is good practice to implement quality control checks as outlined in Chapter 6 (Quality Assurance/Quality
Control and Verification), Volume 1 of the 2006 IPCC Guidelines. Additional quality control checks and quality
assurance procedures may also be applicable, particularly if higher-tier methods are used to estimate carbon
stock changes and non-CO2 GHG emissions. A detailed treatment of inventory QA/QC for field measurement is
described in Section 6.7.1.3, Volume 1 of 2006 IPCC Guidelines.
Whilst Quality Control (QC) is a system of routine technical activities to assess and maintain the quality of theinventory as it is being compiled and it is performed by personnel compiling the inventory, Quality Assurance(QA) is a planned system of review procedures conducted by personnel not directly involved in the inventory
compilation/development process. Verification refers specifically to those methods that are external to theinventory and apply independent data, including comparisons with inventory estimates made by other bodies or
through alternative methods. Verification activities may be constituents of both QA and QC.
Some important issues are highlighted and summarised below.
When compiling data, it is good practice to cross-check estimates of GHG emissions and removals against
independent estimates. For instance, it is good practice that the inventory compilers:

Cross-reference aggregated production data (e.g. crop yield, tree growth) and reported area statistics withnational totals or other sources of national data (e.g. agriculture / forestry statistics);



Calculate implied emission/removal factors ;Compare implied emissions/removals factors and other parameters with default values and data from othercountries;Compare results, for each Article 3.3 and 3.4 activity, from two different sources, such as national statistical
data versus remote sensing source or two different remote sensing sources (e.g. Dymond et al., 2012), or two
methods (gain-loss and stock-difference method).

It is also good practice to check that the sum of the disaggregated areas used to estimate the various
emissions/removals equals the total area under the activity, reported as per guidance in Chapter 6, Volume 1 of2006 IPCC Guidelines (using the land-use change matrix). Checks that can be used in QA/QC are listed in Box
2.4.2.

BOX 2.4.2
QA/QC CHECKS OF LULUCF ESTIMATES

Checks:
Does the inventory document the data, assumptions and inferences used for estimating emissions
and removals for all IPCC source/sink categories?
Have all carbon pools according to paragraph 26 of the Annex to Decision 2/CMP.7 been reported
in the inventory?
If a sink/source category or pool or gas has been excluded, does the report explain why?
Are emissions and removals reported as positive and negative terms, respectively?
For each activity, is the area reported consistently reported across the time series?
Are any discontinuities in trends from base year to last reported year evaluated and explained?
Are geographical boundaries of each land subject to Article 3.3 and 3.4 activities specified?
Is the total land area reported under Article 3.3 and 3.4 constant or increasing over time?
Is information provided to distinguish deforestation from harvesting (clear- cut) or forest
disturbance followed by re- establishment of a forest?
Is the forest definition consistent with that historically used by the Party for reporting information
under international bodies (including the UNFCCC)? Is that definition applied consistently overtime and among activities (i.e. FM, AR, D)?

Verification

Generic good practice guidance for verification is given in Section 6.10, Volume 1 of the 2006 IPCC Guidelines(Verification). It is also good practice to develop verification activities as part of the overall QA/QC andverification system. Specific guidance and further issues are provided in the sections below.

S PECIFIC GUIDANCE FOR VERIFICATION OF LULUCF
INVENTORIESThe checklist in the Box 2.4.3 summarises some of the tools that can be used for internal verification of a GHG
inventory in the LULUCF Sector.
BOX 2.4.3
VERIFICATION OF LULUCF ESTIMATES

A. Comparisons of data:
Compare estimates with independently prepared estimates for the same country or compare
regional sub- sets of the national inventory with independently prepared inventories for thoseregions (Approach 1*).
Compare activity data and/or emission factors and implied emission factors of the estimate withindependent international databases and/or equivalent elements of estimates of other countries. For
example, compare Biomass Expansion Factors of similar species with data from countries withsimilar forest conditions (Approach 1).
Compare the estimate with results calculated using another tier methodology, including the IPCC
defaults (Approach 2).
Compare the estimate with available intensive studies and experiments (Approach 1- 3).
Compare land areas and biomass stocks used for preparing the estimate with remote sensing (landareas) and forest inventories (biomass stock) data (Approach 4).
Compare the estimate with models (Approach 5).
B. Comparisons of uncertainties:
Compare uncertainty estimates with uncertainty reported in the literature.
Compare uncertainty estimates with those from other countries and the IPCC default values.
C. Direct measurements:
Carry out direct measurements (such as time series of local forest inventory, detailed growthmeasurements and/or ecosystem fluxes of GHGs, Approach 3).
* See Section 5.7 of GPG-LULUCF for the details on each Approach.

Taking into account resource limitation, the information provided in the National Inventory Report should beverified as far as possible, particularly for Key Categories.
It is good practice to perform verification with at least one of the approaches listed in Box 2.4.3 (see also Table
5.7.1 and Section 5.7.2 in GPG-LULUCF for more information on the applicable approaches).
If independent estimates on GHG emissions and removals are not available, then internal or external verification
will most probably be limited to scrutiny of the data and methods. Under these circumstances, it is good practicefor the inventory compiler to carry out these checks and to provide sufficient documentation in the national
inventory report and other supporting material to facilitate external review.

S PECIFIC ISSUES LINKED TO THE K YOTO P ROTOCOL

An inventory compiler can use the questions in Box 2.4.4 to help guide the development of a verification planfor supplementary information reported under Articles 3.3 and 3.4 of the KP.
BOX 2.4.4
GUIDANCE FOR VERIFYING CARBON POOLS AND ACTIVITIESWhich carbon pools to verify?
It is good practice to focus verification on those carbon pools that are expected to be most relevantto the KP but also on non- CO2 GHG emissions. The Decision 2/CMP.7 lists the following pools:
above-ground and below-ground biomass, litter, dead wood, soil organic carbon and harvested
wood products. A Party may exclude particular pools, with the exception of HWP, fromaccounting, if verifiable information is provided showing that the pool has not been a source of
GHGs for that particular Article 3.3, FM or elected Article 3.4 activity. As for LULUCF
inventories, if a pool is expected to change significantly over the inventory reporting period,
particular attention should also be devoted to it. Data on carbon stock changes in reported carbon
pools can be verified by assessing the mass balance of carbon stocks, carbon transfers between
pools, and C emissions.
Which supplementary information to verify?
According to Decision 2/CMP.7, a Party has to report activities under Article 3.3 and FM, and may
choose to report any or all elective activities under Article 3.4 of the KP. For all mandatory orelected activities, supplementary information that is specific to the reporting under KP includes:
the identification of the areas in which such activities have taken place, demonstration that theactivities have occurred since 1st January 1990 and are direct human-induced. Further,demonstration of the methodological consistency between the reference level or the base year for
FM and eligible Article 3.4 activities should be reported. To verify land identification, including
the year of the onset of the activity, the use of alternative independent data sources, e.g. remotelysensed data, is good practice, as such independent information contributes to verification.
The reporting of GHG emissions and removals of most Article 3.3 and 3.4 activities requires reference to 1990
or pre- 1990 data (classification of forest/non forest lands for 1990, or base year information for CM, GM, RV
and WDR, etc.). In some cases, these data may not be available or their reliability may be limited. In such cases,
it is good practice to verify the methods and data as much as possible.
Inventory compilers, taking into account national circumstances, including resource availability, may choose theproper combination of approaches for verifying supplementary information reported under the KP. Among thoselisted, Approaches 1 and 2 can be easily implemented by an inventory compiler with low to moderate resources.
Remote sensing is the most suitable for the verification of land areas. Direct measurements (under C in Box
2.4.3) are relevant, although this approach can be resource intensive and, on a large scale, costs may be aconstraint. Models can be used as an alternative when direct measurements combined with remote sensing are
not feasible. Some verification steps, which are unique to the KP, are presented in Box 2.4.4.
For verification, it is good practice to give priority to Key Categories as well as estimates with high uncertainty
or with relevance to mitigation policies, or to carbon pools with a significant change, or all of these, when
implementing the verification plan.

2.5

AFFORESTATION AND REFORESTATIONThis section addresses specific methods applicable to Afforestation and Reforestation (AR) activities and should
be read in conjunction with the general discussion in Sections 2.2 to 2.4.

2.5.1

Definitional issues and reporting requirements

According to the definitions in Decision 16/CMP.1, both Afforestation and Reforestation refer to direct humaninduced conversion of non-forested land to forested land. For the first and second commitment period of the KP,
AR activities are restricted to those that occurred since 1990. The distinction between Afforestation and
Reforestation is linked to the period of time the land has been non-forested. Afforestation occurs on land that has
not been forested for at least 50 years. Reforestation occurs on land that has been forested more recently but has
been converted to non-forest land, and was non-forested on 31 December 1989 66. Land that was subject toDeforestation (D), and is subsequently subject to regrowth of forests continues to be reported under D as a
subcategory (see Section 1.2).
The country’s definition of forest should be consistent with guidance provided in Section 1.2, and consistent
with that used by the country in the first commitment period. A direct human-induced increase in forest cover
meeting, or with the potential to meet, the country-specific forest thresholds is required as a precondition toreport a land under AR activity. AR definitions do not include regrowth of forests following harvest or natural
disturbance of forests. This is because the loss of forest cover in these cases is only temporary and the landremains as forested land. Harvesting followed by re-establishment of forest is considered a Forest Management(FM) activity (Section 2.7). Lands that would be subject to AR activity under Article 3.3 but are instead
accounted for under FM activity under the Carbon Equivalent Forest Conversion (CEFC) provision should be
identified separately (Section 2.7.7).
For identification of lands, Afforestation and Reforestation will be discussed together because the two definitions
differ only by the time since the area was last forested, and because the same carbon reporting and accounting
rules apply to both activities. When calculating changes in carbon stocks following AR, assumptions about theinitial size and composition of the litter, dead wood, and soil organic matter pools should reflect the precedingland-use type and history, rather than the distinction between afforested and reforested sites.
A Party’s choice of methods for the development of an inventory of AR activities will depend on national
circumstances. For the identification of lands subject to AR since 1990, it is good practice to use Approach 3 forconsistent representation of lands (see Section 3.3, Chapter 3, Volume 4 of the 2006 IPCC Guidelines), or
Approach 2, with supplementary information provided that allows identification and tracking of lands on a
statistical basis67. A general discussion of methods for identifying and reporting on lands subject to AR activities
is presented in Section 2.2 of this supplement. It is good practice to provide information on uncertainties in
estimates of the total area of the lands subject to AR, as discussed in Section 2.4.3 of this supplement.
The annual inventory should, at a minimum, identify (for Reporting Method 1 in Section 2.2.2):the geographical location of the boundaries of the areas that encompass lands subject to AR activities- thegeographical boundaries which are reported should correspond to strata in the estimation of land areas as
described in Chapter 3, Volume 4 of the 2006 IPCC Guidelines;

for each of these areas, or strata, an estimate of the area of lands subject to AR activities under Article 3.3 ofthe KP; and66

This date is contained in the definition of reforestation for the first commitment period given in paragraph 1(c) of Annex toDecision 16/CMP.1 (Land use, land-use change and forestry) contained in document FCCC/KP/CMP/2005/8/Add.3, p.5:
Reforestation” is the direct human-induced conversion of non-forested land to forested land through planting, seeding
and/or the human-induced promotion of natural seed sources, on land that was forested but that has been converted to
non-forested land. For the first commitment period, reforestation activities will be limited to reforestation occurring on
those lands that did not contain forest on 31 December 1989. Paragraph 2 of Decision 2/CMP.6 contained in document
FCCC/KP/CMP/2010/12/Add.1, p.5, indicates that: [...]the definitions of forest, afforestation, reforestation, revegetation,
forest management, cropland management and grazing land management shall be the same as in the first commitment
period under the Kyoto Protocol. This supplement assumes that the date of 31 December 1989 continues to be applicablein the second commitment period, but notes that a different interpretation may be possible subject to future decisions of the
CMP.
67
In the case of AR, the minimum information required is the land use that preceded the afforestation/reforestation event.
This is particularly important for estimating the carbon stock change in soil, which may depend on the previous land use
and soil type.

2.73

Chapter 2: Methods for estimation, measurement, monitoring and reporting

the area of lands subject to direct human-induced AR in each of the previous land-use categories (e.g.
Cropland, Grassland). This is to support transparent calculation of carbon stock changes and non-CO2 GHG
emissions and identification of lands.

A more comprehensive system (Reporting Method 2 in Section 2.2.2) identifies each unit of land subject to AR
activities since 1990 using the polygon boundaries, a coordinate system (e.g. the Universal Transverse Mercator(UTM) Grid or Latitude/Longitude), or a legal description (e.g. those used by land-titles offices) of the locationof the land subject to AR activities. Chapter 3, Volume 4 of the 2006 IPCC Guidelines (Consistent
Representation of Lands) discusses in detail the possible Approaches for consistent representation of land areas.
In both cases, it is good practice to provide information on the area of AR activities by year, and any otherinformation relevant for the estimation of emissions and removals (e.g. species, growth rate by species and / orsite conditions, productivity classes, etc.).

2.5.2

Choice of methods for identifying lands subject todirect human-induced Afforestation/Reforestation

Parties are required to report on carbon stock changes and non-CO2 GHG emissions during the commitment
period on areas that have been subject to AR activities since 1990. The first step in this process is to makenational parameter choices for the forest definition within the ranges indicated in Decision 16/CMP.1, namely
minimum area of 0.05–1 ha, minimum tree crown cover of 10-30% (or equivalent stocking level), and minimum
height at maturity of 2-5 m, and to report on these parameters in the annual greenhouse gas inventory. As
explained in Section 2.2.6.1, it is also good practice to choose a parameter for the minimum width of forested
areas. Once the parameters have been chosen, they will be used in identifying lands subject to AR.
The identification of lands subject to AR activities requires the determination of areas that:1.

meet or exceed the size of the country’s minimum area in the applied forest definition (i.e. 0.05-1 ha); and2.

did not meet the country’s definition of forest on 31 December 1989; and3.

meet (or have the potential to meet) the definition of forest at the time of the assessment as the result of
direct human-induced activities; and4.

do not meet the criteria for CEFC at the time of the assessment if this provision is applied.

Note that the definition of forest can be met by young trees that do not yet meet the minimum height or tree
crown cover criteria, provided that they are expected to reach these parameter thresholds at maturity.
It is good practice to distinguish those areas that did not meet the tree crown cover threshold in the definition offorest, for example because of recent harvest or natural disturbances, from those areas that were non-forested on
31 December 1989, because only the latter areas are eligible for AR activities under Decision 16/CMP.1.
Decision 16/CMP.1 requires that Parties provide information on the criteria used to distinguish harvesting orforest disturbance that is followed by the re-establishment of forest from deforestation68. It is good practice toapply the same criteria when evaluating whether land meets the definition of forest. For example, if a country
uses the criterion “time since harvest” to distinguish temporary forest cover loss from deforestation, andspecifies that a harvested area will regenerate within X years, then only those areas that have been harvested formore than X years prior to 31 December 1989 and that have not regenerated would be eligible for reforestation,
as only they would be considered non-forested on 31 December 1989. Similarly, areas that have been disturbed
by wildfire or other natural disturbances (Section 2.3.9) more than X years prior to 31 December 1989 and thathave not regenerated to forest are classified as non-forested on 31 December 1989 and would therefore be
eligible for Reforestation.
As discussed in Section 2.2.2 (Reporting Methods for lands subject to Article 3.3 and 3.4 activities), Parties havethe option either to report a wall-to-wall estimate of all lands subject to Article 3.3 activities, or to stratify theland into areas, i.e. to define the boundaries of these areas and then develop for each area statistical estimates ofthe lands subject to AR and D activities. Combined approaches are also possible: wall-to-wall can be developed
for some strata, while estimates based on sampling approaches are developed for other strata in the country,
ensuring consistency in land representation in order to avoid double counting.

2013 Revised Supplementary Methods and Good Practice Guidance Arising from the Kyoto Protocol

Chapter 2: Methods for estimation, measurement, monitoring and reporting

It is necessary to provide information demonstrating that all AR activities included in the identified lands are
direct human-induced69. Relevant information includes documentation demonstrating that a decision has beentaken aimed at replanting or promoting or allowing forest regeneration, for example referencing laws, policies,
regulations, management decisions, or practices. It may also include identification in field. In the absence ofsuch information, forest regrowth as a consequence of abandonment does not qualify as direct human-induced
AR. Forest regrowth as a consequence of environmental change (including global climate change), for example,
vegetation thickening at high elevation or high latitude tree lines, is not direct-human induced and therefore does
not qualify as AR.
In some cases it may be unclear whether newly established trees have the potential to meet the forest definition.
Where it is uncertain whether trees on a land have the potential to exceed the thresholds of the definition offorest, it is good practice that if the land was already included in KP reporting, the carbon stock changes andnon-CO2 GHG emissions on these lands continue to be reported under that reported activity and to await
confirmation (at a later time) that all the thresholds have been or will be passed before reporting these areas asAR. This approach is consistent with the treatment of D, i.e. after loss of forest cover that may be temporary,lands remain as forested lands until confirmed as D (see Section 2.6.2.1). A decision tree for determining
whether an area will qualify for AR is given in Figure 2.5.1. If newly established vegetation does not pass theforest threshold it may be reported under other elected KP activities, e.g. RV (see Section 2.11).

69

Decision 16/CMP.1 defines AR as the direct human-induced conversion of [land that has not been forested for 50
years/non forested land] to forested land through planting, seeding and/or the human-induced promotion of natural seed
sources. Decision 2/CMP.7 maintained the same definitions. Consistently, according to paragraph 4(a) of Annex II to
Decision 2/CMP.8 (Implications of the implementation of decisions 2/CMP.7 to 5/CMP.7 on the previous decisions on

under the Kyoto Protocol, additional to the reporting requirements under the UNFCCC. Due to this difference, it is possiblethat some areas that have been reported as Land Converted to Forest Land since 1990 in the UNFCCC inventory have notbeen converted through direct human-induced activity and cannot therefore be accounted for under AR activity under the
Kyoto Protocol.

2.5.3

Choice of methods for estimating carbon stockchanges and non-CO 2 GHG emissions

Estimation of carbon stock changes and non-CO2 GHG emissions from AR activities should be consistent withthe methods set out in Section 4.3 (Land Converted to Forest Land), Chapter 4 (Forest Land), Volume 4 of the2006 IPCC Guidelines and equations contained therein, and applied at the same or higher tier as that used for
UNFCCC reporting. Growth characteristics of young trees differ from those of the managed forest as a whole,and special provisions may be needed where the UNFCCC inventory (prepared according to Section 4.3: Land
Converted to Forest Land) is not sufficiently detailed to provide information that applies to young stands.
For AR under Article 3.3 activities, gross-net accounting rules are applied and information on carbon stockchanges and non-CO2 GHG emissions in the base year is therefore not required70. Only net carbon stock changes
and non-CO2 GHG emissions during each year of the commitment period are estimated and reported.
It is good practice to estimate emissions and removals of the harvested wood products (HWP) pool associatedwith AR activities using the guidance provided in Section 2.8 (Harvested Wood Products) of this supplement.
Carbon stock changes and non-CO2 emissions for the three tiers are determined using guidance provided in
Section 4.3 (Land Converted to Forest Land), Chapter 4, Volume 4 in the 2006 IPCC Guidelines.
Determination of the size and dynamics of litter, dead wood and soil organic matter pools prior to the AR
activity may require the use of methods developed for Cropland or other land uses (Chapter 5 and other relevant
chapters of the 2006 IPCC Guidelines).
Definition of pools under AR should be consistent with Section 1.2.2 (Carbon pool definitions and non-CO2
gases) and Table 1.1, Chapter 1, Volume 4 of the 2006 IPCC Guidelines.
It is good practice to report carbon stock changes and non-CO2 GHG emissions from organic soils associatedwith drainage and rewetting of wetlands on lands subject to AR activities using the guidance provided in Section
2.12.4 (Wetland Drainage and Rewetting: Choice of methods for estimating GHG emissions and removals) of

Supplement.

2.5.3.1

P OOLS AFFECTED BY A FFORESTATION /R EFORESTATIONACTIVITIESAR activities may involve site preparation (slashing and possibly burning coarse biomass residue, and tilling or
ploughing on parts of or the whole area), followed by planting or seeding. These activities may affect not only
above- and below-ground biomass pools, but also soil organic matter, as well as dead wood, and litter, if (in thelatter instances) land with woody shrub or sparse tree crown cover was afforested.
Decision 16/CMP.1 requires Parties to estimate carbon stock changes in all five pools (see Table 1.1, Chapter 1,
Volume 4 of the 2006 IPCC Guidelines) during the commitment period unless the Party can demonstrate bytransparent and verifiable information that the pool is not a source71, for which good practice guidance is set out
in Section 2.3.1 of this supplement. Decision 2/CMP.7 further requires Parties to estimate carbon stock changes
in the HWP pool. It is good practice to include carbon stock changes and non-CO2 GHG emissions that result
from pre-planting activities, such as site preparation or shrub removals. AR on mineral soils may maintain or
create conditions that increase below-ground carbon stocks, particularly if the land was previously managed forannual crop production (Post and Kwon, 2000; Merino et al., 2004; Schulp et al., 2008; Laganière et al., 2010;
Don et al., 2011). Under certain circumstances, soil carbon may decline with afforestation of grasslands or
wetlands for several years following conversion (Davis and Condron, 2002; Guo and Gifford, 2002; Vesterdal etal., 2002; Paul et al., 2003; Tate et al., 2003) and net losses of carbon after planting or seeding can persist overmany years. It is therefore good practice to ensure that estimates of pre-activity carbon stocks in the area areused to compute stock changes, including for methodologies involving modelling. Since there is no forest on thearea prior to the AR activity, the methods given in the 2006 IPCC Guidelines (Section 4.3: Land Converted toForest Land, Chapter 4, Volume 4) for estimating non-CO2 GHG emissions on Land Converted to Forest Landare applicable for AR activities.
For AR activities that begin during the commitment period, reporting for that land is required by Decision
2/CMP.8 to start at the onset of the activity 72 . Site preparation and seeding/planting activities should be

M ETHODS TO ADDRESS NATURAL DISTURBANCE

Calculation of carbon stock changes and non-CO2 GHG emissions on areas subject to AR can be influenced by
the presence of natural disturbances, i.e. non-anthropogenic events or non-anthropogenic circumstances thatcause significant emissions in forests and are beyond the control of, and not materially influenced by a Party.
Decision 2/CMP.7 allows that under certain conditions, emissions from natural disturbances that occur in forests
may be excluded from accounting under the KP for the second commitment period. Methods for addressing
natural disturbances are provided in Section 2.3.9: Disturbances.

DEFORESTATIONThis section addresses specific methods applicable to Deforestation (D) activities and should be read in
conjunction with the general discussion in Sections 2.2 to 2.4.

2.6.1

Definitional issues and reporting requirements

According to the definition in Decision 16/CMP.1, “Deforestation” is the direct human-induced conversion offorested to non-forested land 73 . For the second commitment period, Each Party…shall, for the purpose of
applying the definition of forest as contained in decision 16/CMP.174, apply the definition of forest selected in
the first commitment period75 (see Section 1.2). The definition of Deforestation does not include loss of forest
cover due to harvest or natural disturbance events that are followed by natural or human-induced reestablishment of forest. This is because in these cases, a temporary loss of forest cover that is not associatedwith a land-use change is not considered D, and the land remains as forested land.
Harvest followed by re-establishment of forest is considered FM activity and is reported according to Section 2.7.
Natural disturbance followed by re-establishment of forest is not considered as D and disturbance emissions may
be excluded from accounting provided the relevant provisions are met, as explained in the methodologies in
Section 2.3.9. Human activities (since 1990) such as agricultural practices or the construction of roads orsettlements, that prevent forest regeneration by changing land use on areas where forest cover was removed by anatural disturbance, are considered direct human-induced D. All emissions and removals on lands subject to D
must continue to be reported under D, even if these lands subsequently gain forest cover; it is good practice toreport these lands as a separate subcategory76.
AR land that is subject to deforestation is classified under D.
Following Decision 2/CMP.7 and Decision 2/CMP.8,77 it is mandatory to report and account for all emissions
and removals arising from the conversion of natural forest to planted forest under FM. This is not considered D,
because the land remains under forest land use (Section 2.7). Under Decision 2/CMP.778, planted forest lands
subject to conversion to non-forested land may, in special circumstances, be identified and accounted for as FM
activity under the CEFC provisions and are not considered D (Section 2.7.7).
Parties will need to use the methods outlined in Chapter 3, Volume 4 of the 2006 IPCC Guidelines (Consistent
Representation of Lands), and the guidance in Section 2.2 of this supplement to ensure that lands subject to D are
adequately identified in land-use change and other inventory databases and can be tracked over time onceaccounted under the KP. Land identification and tracking provide means to associate the relevant activity data to
the correct emission factor. Decision 2/CMP.879 requires that areas subject to direct human-induced D since1990 (Article 3.3) be identified separately from areas subject to direct human induced D that are also subject toother elected activities under Article 3.4 (such as CM). Providing information on these areas will improvetransparency and ensure that carbon stock changes and non-CO2 GHG emissions are not counted twice.
A Party’s choice of methods for the development of an inventory of lands subject to D activities will depend on
national circumstances. For the identification of lands subject to D since 1st January 1990, it is good practice to73

Treating deforested areas that are subsequently subject to a gain of forest cover as a separate sub-category is useful fortransparency purposes, because different methods may be applied and different emission patterns may be reported for thesesubcategories.

Chapter 2: Methods for estimation, measurement, monitoring and reportinguse Approach 3 for consistent representation of lands (see Section 3.3.1, Chapter 3, Volume 4 of the 2006 IPCC
Guidelines), or Approach 2 with supplementary information provided that it allows identification and tracking oflands on a statistical basis80. Section 2.2.2 of this report provides a general discussion of methods for reportingon lands subject to Article 3.3 activities. It is good practice to provide information on uncertainties in estimatesof the total area of the lands subject to D as discussed in Section 2.4.3 of this report.
The annual inventory should, at a minimum, identify (for Reporting Method 1 in Section 2.2.2):the geographical location of the boundaries of the areas that encompass lands subject to direct humaninduced D activities; the geographical boundaries which are reported should correspond to strata in theestimation of land areas as described in Chapter 3, Volume 4 of the 2006 IPCC Guidelines;

for each of these areas, or strata, an estimate of the area of the lands subject to direct human-induced D
activities under Article 3.3 of the KP, and the area of these lands which would otherwise be included inlands subject to elected activities under Article 3.4 of the KP (CM, GM, RV and WDR); andthe area of lands subject to direct human-induced D in each of the new land-use categories (Cropland,
Grassland, Settlements, Wetlands and Other Land) and areas of lands subject to direct human-induced D thatare subsequently subject to a gain of forest cover. This is to support the transparent calculation of carbon
stock changes and non-CO2 GHG emissions and identification of lands.

A more comprehensive system for compiling annual inventory (Reporting Method 2 in Section 2.2.2) identifies
each unit of land subject to D since 1990 using the polygon boundaries, a coordinate system (e.g. the Universal
Transverse Mercator (UTM) Grid or Latitude/Longitude) at possible finer resolution, or a legal description (e.g.
those used by land-titles offices) of the location of the land subject to D activities. Chapter 3, Volume 4 of the2006 IPCC Guidelines (Basis for Consistent Representation of Lands) discusses in detail the possible
Approaches for consistent representation of lands.
It is good practice to provide information on the area deforested by year, and any other information relevant to
the estimation of emissions and removals (e.g. forest type, site conditions, etc.).

2.6.2

Choice of methods for identifying lands subject todirect human-induced Deforestation

Parties are required to report carbon stock changes and non-CO2 GHG emissions during the commitment period
on land areas that have been subject to direct human-induced D activities since 1990 (after 31 December 1989) .
To quantify D, forest must first be defined in terms of potential height, crown cover, and minimum area, as
already described for AR activities. The same threshold criteria applied for the Party’s definition of forest (seeSection 1.2) must be used for determining the area of land subject to D.
Once a Party has chosen its definition of forest, the boundaries of the forest area can be identified at any point intime. Only areas within these boundaries are potentially subject to D activities.
The identification of lands subject to D activities requires the determination of areas that:1.

meet or exceed the size of the country’s minimum forest area (i.e. 0.05-1 ha); and2.

have met the country’s definition of forest on or after 31 December 1989; and3.

have ceased to meet the definition of forest at some time after 1 January 1990 as the result of direct
human-induced conversion from forested to non-forested land; and4.

do not meet the criteria for CEFC if this provision is applied.

Lands can only be classified under D if they have been subject to direct human-induced conversion from forested
to non-forested land. Areas in which forest cover was lost as a result of natural disturbances are therefore notconsidered D even if changed physical conditions delay or prevent regeneration, provided that these changes inphysical conditions are not the result of direct human-induced actions (Section 2.3.9). Natural disturbancefollowed by land-use change will prevent regeneration of forest and is classified as Deforestation. Change inmanagement or policy that could reasonably be expected to result directly in forest cover loss is considered to be
direct human-induced D. For example, loss of forest cover in areas that have been flooded as a result of changed
drainage patterns due to hydroelectric dams or road construction. Loss of forest cover due to environmental
change (i.e. not direct human induced) not subject to land-use change, would not be considered D (e.g. naturalraising or lowering of water tables in areas with permafrost thawing or river/coastal erosion).
80

In the case of D, the minimum information required is the land use (or land uses) that followed the deforestation event.

2.6.2.1

D ISCRIMINATING BETWEE N DEFORESTATION AND
TEMPORARY LOSS OF FO REST COVER

Parties are required to report on how they distinguish between D and areas that remain forests but where tree
crown cover has been temporarily removed81, notably areas that have been harvested or have been subject toother human disturbance but where it is expected that a forest will be replanted or will regenerate naturally. It isgood practice to develop and report criteria by which temporary removal or loss of tree cover can be
distinguished from D. For example, a Party could define the expected time period (years) between removal oftree cover and successful natural regeneration or planting. The length of these time periods could vary by region,
biome, species and site conditions. In the absence of land-use change (such as conversion to Cropland or
construction of settlements) areas without tree cover are considered “forest” provided that the time since forest
cover loss is shorter than the number of years within which tree establishment is expected. After that time period,
lands that were forest on or after 31 December 1989 and that have since lost forest cover due to direct humaninduced actions and failed to regenerate are identified as deforested; carbon stock changes and non-CO2 GHG
emissions for these lands are therefore to be recalculated and added to those of other deforested areas. There isalso an exception under the CEFC, which allows the carbon stock changes and non-CO2 GHG emissions fromsome plantation conversions to non-forest to be reported under Forest Management if a Carbon Equivalent
Forest is established elsewhere (see Section 2.7.7).
Although the loss of forest cover is often readily identified, e.g. through change detection using remote sensing
images or field inventories, the classification of an area as deforested and the identification of the new land use
may be more challenging. This involves assessing the lands on which the forest cover loss has occurred, as wellas the surrounding area, and typically requires data from multiple sources to supplement the change detection

information. In some cases a new land use can be determined from remotely sensed data, for example where it ispossible to identify agricultural crops or infrastructure such as houses or industrial buildings. Information about
actual or planned land-use changes and actual or planned forest regeneration activities can be used to distinguish
D from temporary loss of forest cover. Where such information is missing or unavailable, only a lapse of time
will reveal whether or not the forest cover has been temporarily lost. In the absence of land-use change orinfrastructure development and until the time for regeneration has elapsed, these lands remain classified as forest.
If the land does not meet the definition of forest once the time period has elapsed, it is classified as D and the
new land use is determined. It could be the case that the information needed to distinguish D from temporary
loss of forest cover (e.g. the expected time for regeneration has elapsed) will be available only in the following
commitment period. To avoid potential underestimation of emissions from D in the commitment period, it isgood practice to estimate by the last inventory reporting year of the commitment period, the proportion of lands
without forest cover that is expected not to regenerate to forest82. This estimate could be based on countryspecific or regional averages or on other spatial data consistent with national inventory methods. This proportionof the area will then be assigned to lands subject to D, while the remaining proportion will remain classified asforest83.
It is good practice for Parties to identify and track lands with loss of forest cover that are not yet classified as
deforested, and to report on their area and status in annual supplementary information (see Table 2.4.1 in Section
2.4.4.1). It is also good practice to confirm whether or not regeneration occurred within the expected time periodon these lands. Lands for which, at the end of a commitment period, no direct information was available todistinguish D from other causes of forest cover loss, could be reassessed annually or at a minimum prior to theend of the next commitment period. If regeneration did not occur or if other land-use activities are observed, thenthese lands that had remained classified as forest should be reclassified as D and carbon stock changes and nonCO2 GHG emissions calculated accordingly (see also Chapter 5, Volume 1 of the 2006 IPCC Guidelines: Time
Series Consistency).
The task of distinguishing temporary forest cover loss from D can be supported by information on harvested
areas and areas subject to natural disturbances. In many countries, information on harvest cut blocks and on
natural disturbance events is more readily available than information on deforestation events. Such information
can be used to distinguish direct human-induced D from temporary forest cover loss (e.g. harvest) or nonhuman- induced disturbances (e.g. wildfire or insect outbreak). Attribution of the cause of forest cover loss to theremaining areas would be made easier and would support the identification and verification of lands subject to D.
A decision tree for determining whether a unit of land is subject to direct human-induced D is given in Figure
2.6.1.

82

This method is necessary because emissions on affected lands may not necessarily be reported under FM.
For instance, in the last inventory year of the commitment period, an area of 1000 ha was subject to loss of forest cover;
800 ha of this area were classified as D, while the information needed to classify the remaining 200 ha definitively as D
was still not available. Of these 200 ha, based on country-specific or regional statistics or other data, the country estimatesthat 150 ha are expected not to regenerate. These 150 ha are assigned to D, while the remaining 50 ha remain classified asforest.

2.6.3

Choice of methods for estimating carbon stockchanges and non-CO 2 GHG emissions

All carbon stock changes and non-CO2 GHG emissions during the commitment period on lands subject to direct
human-induced D since 1990 are required to be reported84. Where deforestation occurred between 1 January
1990 and the beginning of the commitment period, changes in the carbon pools after the deforestation event need
to be estimated for each inventory year of the commitment period85. After the deforestation event, losses during
the commitment period will result primarily from continuing decay of dead wood, litter, below-ground biomass
and soil carbon remaining on the site. These losses can be offset by an increase in biomass pools on this land.
Definitions of pools under D should be consistent with provisions introduced by the 2006 IPCC Guidelines(Section 1.2.2, Chapter1, Volume 4: Carbon pool definitions and non-CO2 gases and Table 1.1).
On areas subject to Article 3.3 activities, gross-net accounting rules are applied86 and information on carbon
stock changes and non-CO2 GHG emissions in the base year is therefore not required. Only net carbon stockchanges and non-CO2 GHG emissions during each year of the commitment period are required to be estimatedand reported.
HWP derived from D activity are accounted for as an instantaneous emission at the time of deforestation (seeSection 2.8).
For the estimation of carbon stock changes and non-CO2 GHG emissions, it is good practice to use the same or ahigher tier as that used for estimating emissions from forest conversion in Chapters 5, 6, 7, 8 and 9 (Conversion
from Forest Land to any other land-use category), Volume 4 in the 2006 IPCC Guidelines.
Carbon stock changes on lands subject to D activities during the commitment period can be estimated bydetermining carbon stocks in all pools prior to and after the deforestation event. Alternatively, stock changes canbe estimated from carbon transfers out of the forest, e.g. the amount harvested (Chapter 2, Volume 4 of the 2006
IPCC Guidelines) or the biomass consumed in the case of burning. For deforestation events that occur prior tothe commitment period, knowledge of pre-deforestation carbon stocks will also be useful for the estimation of
post-disturbance carbon dynamics. For example, estimates of emissions from decay of litter, deadwood, and soilorganic matter pools can be derived from data on pool sizes and decay rates. Information about pre-deforestation
carbon stocks can be obtained from forest inventories, aerial photographs and satellite data, by comparison withadjacent remaining forests, or through reconstruction from stumps where these remain on site. Information on
the time since deforestation, on the current vegetation, and on management practices on that site is required forthe estimation of carbon stock changes and non-CO2 GHG emissions.
It is good practice that carbon stock changes on D lands subject to new land-use categories (such as Cropland,
Grassland, Wetlands, Settlements, or Other Land) be estimated using the established methodologies to estimate
carbon stock changes described in relevant sections of the 2006 IPCC Guidelines. Several of these categories
may contain little or no carbon, or the change in carbon stocks may be very small.
It is good practice to report carbon stock changes and non-CO2 GHG emissions from organic soils associatedwith drainage and rewetting on land subject to D activities using the guidance provided in Section 2.12.4(Wetland Drainage and Rewetting) of this supplement, and in the Wetlands Supplement.
It is good practice to estimate and report non-CO2 GHG emissions and CO2 emissions from liming and urea
application using the guidance provided in Section 2.4.4.2.

FOREST MANAGEMENT

According to Decision 2/CMP.7, accounting of emissions and removals from Forest Management (FM) under
the Kyoto Protocol during the second commitment period is mandatory87, and is based on a reference level88.
This section addresses definitional issues and specific methods for identification of areas subject to FM andcalculation of carbon stock changes and non-CO2 GHG emissions for those areas (Sections 2.7.1, 2.7.2 and2.7.3).
This section also addresses the new elements introduced by Decision 2/CMP.7, including:reporting of emissions arising from the conversion of natural forests to planted forest (within Section 2.7.1);

methodological requirements related to the Forest Management Reference Level (FMRL, Section 2.7.5);

performance of Technical Corrections for accounting purposes (Section 2.7.6); andreporting and accounting of lands under the Carbon Equivalent Forest Conversion provision (CEFC, i.e.
lands under FM that would otherwise be accounted as Article 3.3 lands, Section 2.7.7).

The treatment of HWP related to FM, according to Decision 2/CMP.7, is discussed briefly in this section and in
more detail in Section 2.8. Natural disturbances as they relate to FM are dealt with briefly in Section 2.7.4 below
and in greater depth in Section 2.3.9.
This section should be read in conjunction with the general methodological description in Sections 2.2 to 2.4 ofthis supplement.

2.7.1

Definitional issues and reporting requirements

Decision 2/CMP.7 maintains the same definition of “forest” and “Forest Management” as in Decision
16/CMP.189.
Decision 16/CMP.1 defines “forest” using the threshold criteria90, including the potential to meet them, andincluding areas that are temporarily unstocked. Decision 2/CMP.7 specifies that, for the purpose of applying thedefinition of “forest”, each Party shall apply the definition selected in the first commitment period. See guidance
provided in Section 1.2.
According to Decision 16/CMP.1, “Forest Management” is a system of practices for stewardship and use offorest land aimed at fulfilling relevant ecological (including biological diversity), economic and social functionsof the forest in a sustainable manner. It includes forests meeting the definition of “forest” in Decision 16/CMP.1
with the parameter values for forests that have been selected and reported by the Party, and that have not beenclassified by the Party under AR or D categories.
There are two approaches that countries may choose to interpret the definition of FM. In the narrow approach, acountry would define a system of specific practices undertaken since 1990 that could include stand-level forest
management activities such as site preparation, planting, thinning, fertilization, and harvesting, as well as
landscape-level activities such as fire suppression and protection against insects. In this approach, the area
subject to FM may increase over time if the specific practices defined as FM activities are implemented on new
areas. In the broad approach, a country would define a system of forest management practices, and identify thearea that is subject to this system of practices during the inventory year of the commitment period without therequirement that a specified forest management practice has occurred on each land.
According to Decision 2/CMP.7, Parties are required to report and account for all emissions arising from theconversion of natural forests to planted forests after 31 December 2012. In this context, “conversion” does not
involve a land-use change but refers to replacement of natural forest with planted forests after harvesting. It isgood practice that Parties, according to their national circumstances, provide their definition of natural forest andplanted forest, with the latter including forest plantations (as defined in the 2006 IPCC Guidelines), and apply
these definitions consistently throughout the commitment periods. It is good practice that emissions and87

removals on lands subject to conversion from natural forest to planted forest are reported and accounted forunder FM.
According to Decision 2/CMP.7, Parties applying the CEFC provision described in Section 2.7.7 are required toreport these lands separately from other FM lands. These lands will include both forest and non-forest lands but
are accounted for under FM.
Section 2.2 (Generic methodologies for area identification, stratification and reporting) explains that thegeographical location of the areas encompassing lands subject to FM activities are to be defined and reported91.
Two Reporting Methods are outlined in Section 2.2.2.
In Reporting Method 1, a boundary may encompass multiple FM lands and other kinds of land use such as
agriculture or unmanaged forests. In Reporting Method 2, a Party identifies the geographic boundaries of alllands subject to FM throughout the country. Reporting Methods 1 or 2 are used for reporting carbon stockchanges in above-ground biomass, below-ground biomass, dead wood, litter, and soil organic matter pools aswell as non-CO2 GHG emissions. Reporting and accounting for the HWP pool is at the national level. FM lands
also include non-forest land accounted for under FM through the CEFC provision, if implemented (Section
2.7.7).

2.7.2

Choice of methods for identifying lands subject toForest Management

It is good practice for each Party to describe in its NIR how it applies the definitions of “forest” and “Forest
Management” under Decision 16/CMP.1 in a consistent way across space and time, and how it distinguishes
areas subject to FM from other areas. It is good practice to base the assignment of land to activities following theguidance in Sections 1.1 and 1.2 of this supplement and Chapter 3, Volume 4 (Consistent Representation ofLands) of the 2006 IPCC Guidelines.
Land subject to “Forest Management” as defined by Decision 16/CMP.1 is not necessarily the same area as“managed forest” used for UNFCCC reporting in the context of the 2006 IPCC Guidelines. The latter includes
all forest lands where human interventions and practices have been applied to perform production, ecological orsocial functions (Chapter 2, Volume 4, 2006 IPCC Guidelines), and thus may include forests that do not meet thecountry-specific definition of “Forest Management” under Decision 16/CMP.1 or that have not been subject to
any FM practice since 1990.

If the forest-related land use and land-use change categories under UNFCCC do not meet the requirements of definitionsin Decision 16/CMP.1, they are not included under forest-related activities (AR, D, FM) under the KP reporting. The
figure above is not necessarily exhaustive of all possible cases, e.g. in the case of a Land Converted to Forest Land after 31
Dec 1989, once the time period for UNFCCC reporting of converted lands has elapsed (e.g. 20 years) this land is reported
as Forest Land Remaining Forest Land under the UNFCCC reporting and as AR under the KP reporting (the same
reasoning would apply for Forest Land Converted to non-Forest Land). Therefore, the areas of forest-related land use andland-use change categories under the UNFCCC reporting do not necessarily match the areas of the corresponding forestrelated activities under the KP reporting.

Figure 2.7.1 outlines the relationship between different forest categories. For UNFCCC reporting, countries may
have subdivided their forest area into managed forests (those that are included in the reporting) and unmanaged
forest (in which case areas are reported but not the emissions). Managed forests could further be subdivided into
those areas that meet the definitions of “forest” and of “Forest Management” in Decision 16/CMP.1 and those (ifany) that do not. However, since most countries have in place policies to manage forests sustainably, and/or use
practices for stewardship and use of forest land aimed at fulfilling relevant ecological (including biologicaldiversity), economic and social functions of the forest in a sustainable manner92, the total area of managed forest
in a country will often be the same as the area subject to FM plus any area subject to AR. Where differences
occur between the areas of managed forest (as reported under the UNFCCC) and forest subject to FM (plus any
area subject to AR), it is good practice to explain and document the extent of differences. In particular, whereareas that are considered managed forest are excluded from the area subject to FM, it is good practice to provide
the reason for the exclusion (including the use of the narrow approach), and to document how any possible

unbalanced accounting is avoided. The IPCC Report on Definitions and Methodological Options to Inventory
Emissions from Direct Human-Induced Degradation of Forests and Devegetation of Other Vegetation Types(IPCC, 2003c) discusses the issue of unbalanced accounting. In the context of the FMRL, unbalanced accounting
can occur if areas that are considered more likely to produce a net debit in the accounting are preferentiallyexcluded and areas considered more likely to produce a net credit are preferentially included in FMRL. In
addition, unbalanced accounting may potentially occur where countries increase their area of land under FM
compared to the area included in the FMRL. In the case of increase in FM area during the commitment period
beyond what is included in the FMRL (e.g. when the narrow approach to FM is used), it is good practice todocument transparently that this is not a result of change in the FM activity definition, but rather a result of
newly implemented policies that were not included in the FMRL submission. The inclusion of non-forested areas
within FM accounting under the CEFC provision can also lead to differences between the reported area ofmanaged forest and the area under FM – all such areas must be clearly identified (see Section 2.7.7).
Figure 2.7.2 gives the decision tree for determining whether land qualifies for FM. Land that is classified as
being subject to FM is required to meet the country’s criteria for forest or, if non-forest, is required to be subject
to CEFC provision.

It is good practice for each Party to describe its application of the definition of FM and to identify areas of land
subject to FM in the inventory year of the commitment period. In most cases, this will be based on information
contained in national forest inventories including criteria such as administrative, zoning (e.g. protected areas orparks) or ownership boundaries, since the difference between managed and unmanaged forest or possibly,
between managed forest meeting the definition of FM in Decision 16/CMP.1 and managed forest not doing so,

may be difficult or impossible to detect by remote sensing or through other forms of observation. It is goodpractice for each Party to provide information to show how reporting and accounting of emissions and removals
due to transition of natural forest to planted forest have been captured within FM.
According to Decision 2/CMP.7, carbon stock changes and non-CO2 GHG emissions on lands subject to FM canbe excluded from accounting if they are associated with natural disturbance (see Sections 2.2.3 and 2.3.9).
The area of lands subject to FM can increase or decrease over time, for example, if a country expands its roadinfrastructure into previously unmanaged forests and initiates management activities, or in the case of the narrowapproach, as new specific FM practices are applied to new areas of forest land. In both these cases, the area ofland subject to FM is increasing and the associated carbon stock changes need to be estimated accordingly. If an
area of forest expansion after 1990 does not qualify for direct human-induced AR and if this area meets therequirements of FM under Decision 16/CMP.1, it is included under FM (see Figure 2.7.1). On the other hand, D
activities decrease the area under FM. Where changes in area occur over time, it is essential that the methods forcarbon stock change calculation are applied in the sequence outlined in Section 2.3.3 of this supplement. Failure
to use the correct computational methods may result in an apparent but incorrect increase or decrease in carbon
stocks that is the result of change in area.
Once an area has been included in reporting under the KP it cannot be removed but the reporting category of thearea can change (as outlined in Section 1.3). Lands that are deforested are subject to the rules of Article 3.3 andfuture carbon stock changes must be reported under D. Accordingly, the area reported under Article 3.4 would
decrease, and the area reported under Article 3.3 would increase by the same amount.
Forests plantations that are harvested and converted to non-forest lands under the CEFC provisions are notregarded as being deforested (see Section 2.7.7). These lands are reported under FM, as are the compensating
non-forest lands converted to forest land. This means that the area reported under FM may increase without anincrease in forested land. Decision 2/CMP.7 mandates that lands subject to CEFC provisions be transparently
identified and tracked.

Choice of methods for estimating carbon stockchanges and non-CO 2 GHG emissions

Methods to estimate carbon stock changes and non-CO2 GHG emissions within FM lands follow those in the2006 IPCC Guidelines provided in Section 4.2 (Forest Land Remaining Forest Land), Chapter 4, Volume 4
including in the case of conversion of natural forests to planted forests.
For the HWP pool, estimation methods in line with Decision 2/CMP.7 are provided in Section 2.8 of this
supplement, including guidance to distinguish among HWP originating from lands subject to each forest-related
activity, i.e. AR, FM, or D, or from lands not subject to any of those activities. On areas subject to FM activities,
the reference level accounting rule is applied for the second commitment period, i.e. for each Party accounting isbased on comparison between emissions and removals reported for FM during the commitment period and the
FMRL inscribed in the Appendix to Decision 2/CMP.7 (see Section 2.7.5). In certain cases, it is good practice toapply Technical Corrections for accounting purposes (see Section 2.7.6).
It is good practice to use the same or a higher tier for estimating carbon stock changes and non-CO2 GHG
emissions as the one that was used for the corresponding land use in the UNFCCC inventory, following theguidance on methodological choice and identification of key categories included in Chapter 4, Volume 1 of the2006 IPCC Guidelines. In particular:

Tier 1 can only be applied if FM is not considered a key category or if the pool is not significant, according
to the guidance in Section 2.3.6 (Choice of method) of this supplement. Tier 1, as elaborated in Chapter 4,
Volume 4 of the 2006 IPCC Guidelines, assumes that for Forest Land Remaining Forest Land the netchange in the carbon stocks in litter, dead wood, and soil organic matter pools is zero, but Decision 2/CMP.7
specifies that above- and below-ground biomass, litter, dead wood, and SOC shall all be accounted for2013 Revised Supplementary Methods and Good Practice Guidance Arising from the Kyoto Protocol

2.91

Chapter 2: Methods for estimation, measurement, monitoring and reporting

unless the country chooses not to report changes in a pool that has been demonstrated not to be a source.
Tier 1 can therefore only be applied if the litter, dead wood and soil organic matter pools can be shown not
to be sources using the methods outlined in Section 2.3.1 (Pools to be reported) of this supplement. It is
important to note that, once a pool has been included in the FMRL, for reasons of consistency, this pool isalso required to be reported and accounted for during the commitment period, irrespective of the pool beinga sink or a source (see Section 2.7.5.2 on methodological consistency). For HWP, specific guidance is given
in Section 2.8.


It is good practice to apply Tier 2 and 3 methods if FM is a key category and if the pool is significant,according to the guidance given in Section 2.3.6. With the exception of the pools already included in the
FMRL, a country may decide to exclude those pools that can be shown not to be a net source, using themethods described in Section 2.3.1.

Where it is possible to obtain estimates from both the Gain-Loss and the Stock-Difference methods, it issuggested that a comparison between the two methods be used for verification purposes because this mayhelp identify errors and understand better the trends and reasons for interannual variations.

It is good practice to report carbon stock changes and non-CO2 GHG emissions from organic soils associatedwith drainage and rewetting under FM activities using the guidance provided in Section 2.12.4 (Wetland
Drainage and Rewetting) of this supplement, and in the Wetlands Supplement.
It is good practice to estimate and report non-CO2 GHG emissions and CO2 emissions from liming and urea
application using the guidance provided in Section 2.4.4.2.
In most cases, the information requirements for KP reporting exceed the information contained in the national
UNFCCC inventory. To meet the KP reporting requirements, national inventory systems need be able to identify
and track all forest areas as specified in Section 2.2, whether these are classified as managed forest (UNFCCC)
or subject to Articles 3.3 and/or 3.4 of the KP, and whether they have been subject to natural disturbances or to
the CEFC accounting provisions. Such systems can then be used to calculate and report carbon stock changes
and non-CO2 GHG emissions in all relevant categories for both UNFCCC and KP reporting. Properly
implemented, such a comprehensive approach ensures consistency across the methods used for calculating andreporting carbon stock changes and non-CO2 GHG emissions, because the same forest and land-use change
inventories are the basis for the computations used in both UNFCCC and KP reporting.

Methods to address natural disturbanceCalculation of carbon stock changes and non-CO2 GHG emissions in areas subject to FM can be influenced bynatural disturbances, i.e. non-anthropogenic events or non-anthropogenic circumstances that cause significant
emissions in forests and are beyond the control of, and not materially influenced by a Party. Accounted
emissions from FM can be influenced by natural disturbances in three ways: 1) through emissions from natural
disturbances occurring in the commitment period; 2) through the choice of the background level and the margins;
and 3) through an inconsistency between the treatment of natural disturbances in the reporting of FM emissions
in the commitment period and the FMRL. Methods for addressing natural disturbances in cases 1) and 2) areprovided in Section 2.3.9. Guidance to address inconsistencies in the treatment of natural disturbances inreported data and the FMRL is presented in Sections 2.7.5 and 2.7.6.

Forest Management Reference Levels

According to Decision 2/CMP.793, for the second commitment period, accountable anthropogenic greenhousegas emissions by sources and removals by sinks resulting from Forest Management under Article 3.4, …shall beequal to anthropogenic greenhouse gas emissions by sources and removals by sinks in the commitment period,
less the duration of the commitment period, in years, multiplied by the FMRL inscribed in the appendix [to theDecision]. The FMRL is a value of average annual net emissions and removals from FM in the second
commitment period, against which the net emissions and removals reported for FM during the second
commitment period will be compared for accounting purposes.
This section addresses methodological issues related to the FMRL, including: 1) an overview of approaches andmethods used and the elements taken into consideration by Parties for the construction of their FMRL (2.7.5.1);
2) a description of how to demonstrate methodological consistency between the FMRL and reporting for FM
during the commitment period (2.7.5.2); and 3) a description of how and when to perform Technical Corrections
for accounting purposes, if necessary, to ensure consistency applying IPCC methods, or to exclude fromaccounting any impact due to inconsistencies (2.7.6). This section should be read in conjunction with the generalguidance on FM provided in Sections 2.7.1 to 2.7.4.
The guidance on how to construct the FMRL is provided in Appendix II to Decision 2/CMP.6 and is notrepeated here. The overview of approaches, methods, and elements used in the construction of FMRLs isprovided below to clarify discussions on methodological consistency and Technical Corrections.

O VERVIEW OF APPROACHES , METHODS AND ELEMENTSCONSIDERED IN THE CO NSTRUCTION OF FMRL

Decision 2/CMP.6 requested Annex I Parties to submit information on how the country’s FMRL was constructed
and provided guidelines for the submission of such information. The objectives of the submissions were: 1) toprovide information consistent with the general reporting principles set out by the Convention and elaborated by
the IPCC, on how the elements contained in footnote 1 to paragraph 4 of Decision 2/CMP.694 were taken into
account by Parties in the construction of FMRLs, and to provide any additional relevant information; 2) todocument the information that was used by Parties in the construction of FMRLs in a comprehensive andtransparent way; and 3) to provide transparent, complete, consistent, comparable, and accurate methodologicalinformation used at the time of the construction of the FMRL.
The information provided by Parties on how the FMRL was constructed provides the basis for assessing
methodological consistency between the FMRL and the reporting of FM during the second commitment period.
This section summarises the approaches and methods used and the elements considered in the construction of the
FMRL, based on FMRL submissions made by Parties and on the synthesis report of technical assessments
provided by the UNFCCC Secretariat95.

APPROACHES AND METHODS USED FOR CONSTRUCTING FOREST MANAGEMENT REFERENCE LEVELS

Based on the UNFCCC’s synthesis report of the technical assessments of the FMRL submissions, it emergesthat out of the 38 Parties submitting FMRLs, 17 used country-specific projections, 14 used a common
approach for projections, one proposed a historical average, two proposed extrapolation of historical data,
three proposed historical FMRLs based on a single year, and one proposed an FMRL of zero. The three
approaches used are summarised below. The first approach is further split into two methods.
1)

FMRLs based on projections under a ‘business-as-usual’ scenario. These include two methods:a)modelled projections under a ‘business-as-usual’ scenario

Model-based projections using country-specific methodology. Most of the country-specific approaches
used data from national forest inventory as a source of information on future forest resources, combined withprojections of future harvest demand from partial equilibrium models or scenario analysis.
Model-based projections using a common methodological approach. Several EU countries followed acommon approach developed by the Joint Research Centre (JRC) of the European Commission, in
collaboration with modelling groups from the International Institute for Applied Systems Analysis (IIASA)
and the European Forest Institute (EFI). Two models were used to project annual estimates of emissions andremovals for FM and averaged to calculate the FMRL.
b)projections based on the elaboration of historical data from greenhouse gas inventories, assumed asproxy for a ‘business-as-usual’ scenario

Average of historical data. For its FMRL, one Party used the average of historical removals under theForest Land Remaining Forest Land category.
Extrapolation from a historical time series trend. Two Parties used a linear extrapolation of net
historical emissions data to construct the FMRLs.
2)

Historical FMRL based on the single year 1990

Three Parties proposed the use of a historical FMRL based on 1990 data.
3)

FMRL equal to zero

One Party used the narrow approach for FM and set its FMRL equal to zero.

ELEMENTS CONSIDERED IN THE CO NSTRUCTION OF FMRL
Pools and gases
Decision 2/CMP.6 requested Parties to identify pools and gases which have been included in the FMRL, toexplain the reasons for omitting a pool from FMRL construction (i.e. including evidence for the pool not being asource), and to explain consistency between the pools and gases included in the FMRL and those included in thereporting of FM or Forest Land Remaining Forest Land.
Decision 2/CMP.7 also specified that for the second commitment period, Parties shall account for all changes
in … above-ground biomass, below-ground biomass, litter, dead wood, soil organic matter and harvested wood
products (see Section 2.3.1 for additional information and methodological guidance). Nevertheless, with the
exception of HWP, a Party may choose not to account for a given pool in a commitment period, if transparent
and verifiable information is provided that demonstrates that the pool is not a source.

Area under Forest Management
The FMRL submissions contain information on the FM area used in the construction of the FMRL with the aimof showing consistency with the reporting of FM or Forest Land Remaining Forest Land. Parties also explained
how the area used in the construction of the FMRL relates to the area accounted for as being subject to D and
AR activities. In the case of modelled projections, consistency between FMRL area and area under FM meansthat future D is taken into account by projecting a decreasing FM area in the second commitment period96, and96

Some Parties did not consider the impact of future deforestation rate on the evolution of the FM area, assuming this has aconservative impact on the FMRL value.

2.94

2013 Revised Supplementary Methods and Good Practice Guidance Arising from the Kyoto Protocol

Chapter 2: Methods for estimation, measurement, monitoring and reportingthat the expected future AR does not affect the evolution of FM area considered for the FMRL. In some cases, anincrease in future FM area was included in FMRL due to new forest area (e.g. previously unmanaged) assumed
to enter the FM area.

Historical data from greenhouse gas inventory
Parties were requested to include in the FMRL submissions information on the relationship between FM and
Forest Land Remaining Forest Land as shown in GHG inventories and relevant historical data, including
information provided under Article 3.3, and, if applicable, Article 3.4. The purpose of this information is to show
consistency between the proposed FMRLs and historical data as reported in each Party’s GHG inventory and
NIR. Historical data came from the 2010 GHG inventory, unless otherwise specified. In the case of modelled
projections, consistency with historical data can be shown by the fact that the model used for constructing the
projected FMRL reproduces historical data for FM or Forest Land Remaining Forest Land from the GHG
inventory or that ex-post calibrations have been carried out to align the model results with historical data.

Forest characteristics and related management
The FMRL submissions included information on forest characteristics, including age-class structure, increments,
rotation lengths, and other relevant information, including information on forest management activities alreadyundertaken and assumed under business-as-usual. In many cases, information included forest types, soil types,
growing stock, tree species composition and silvicultural practices (including regeneration modality, type andfrequency of cuttings, etc.). In the case of models used for projected FMRLs, other information included
assumptions about future silvicultural practices, key drivers (i.e. harvest rates), and expected evolution of key
forest characteristics (age structure, increment), with the aim of transparently describing the forest management
activities foreseen under the business-as-usual scenario and to demonstrate their feasibility.

Historical and assumed harvesting rates
Harvest rate is a major driver of net emissions and removals from FM. The FMRL submissions included the timeseries of historical harvesting rates and predicted future harvest rates. In the case of modelled projections, it isparticularly important that the information shows that the historical harvest used by the models is consistent withthe data used in the GHG inventory or, in case harvest is not used in GHG inventories (i.e. if the StockDifference method is used), that the historical harvest used by the models is consistent with official country
statistics.
For projected FMRLs, Parties provided information on assumptions about future harvesting rates, based on
business-as-usual scenarios (i.e. considering domestic policies adopted and implemented no later than December2009). Some Parties used averages of historical harvest rates as a proxy for business-as-usual scenario, whileothers predicted the future harvest amount (or future harvest relative increase or decrease as compared withhistorical period) based on macroeconomic scenarios or based on the continuation of current forest management
activities associated with actual age-class structure. For purposes of transparency, information on theassumptions made on the disaggregation of future harvest, by type of wood use (i.e. industrial wood/wood forenergy use) and/or by assortment types (as feedstock for HWP, see Section 2.8.1) was useful to demonstrateconsistency between biomass losses due to assumed future harvest rates and biomass used for HWP estimates.

Harvested wood products
Many Parties presented in their FMRL submissions values related to the contribution of HWP, assuming either
instantaneous oxidation or a first-order decay function with default half-lives (see Section 2.8). Since FMRLs
were submitted before Decision 2/CMP.7, it is essential to consider the need for a Technical Correction foraccounting purposes in order to reflect Decision 2/CMP.7. See Section 2.8 for detailed information and goodpractice guidance on HWP.

Natural disturbances
Decision 2/CMP.6 also requested Parties to consider including in the construction of their FMRLs information
on disturbances in the context of force majeure (as defined in Decision 2/CMP.6). Most Parties did not consider
disturbances explicitly in the construction of their FMRLs, often noting the low frequency of such events. In
some cases, the average impact of past disturbances was incorporated into the FMRL through the methodologies
used. In other cases, the impact of natural disturbances on FMRL was expressed as a range of possible
disturbances scenarios or as a constant background level of natural disturbances.
Since FMRL were submitted before Decision 2/CMP.7, a Technical Correction for accounting purposes may beneeded if a country intends to apply the provision on natural disturbances for the second commitment period. See
Section 2.3.9 for detailed information and good practice guidance on emissions from natural disturbances.

Chapter 2: Methods for estimation, measurement, monitoring and reporting

Factoring out
Decision 2/CMP.6 required Parties to consider in their FMRL submissions factoring out in accordance withparagraph 1(h) (i) and 1(h) (ii) of Decision 16/CMP.1 (i.e. to factor out removals from elevated carbon dioxide
concentrations above pre-industrial level, indirect nitrogen deposition, and the dynamic effects of age classstructure resulting from activities and practices before the reference year 1990). Parties did not explicitly
consider factoring out in their FMRLs. In the case of historical FMRLs, it is noted that, given the present state ofscientific knowledge, the effects of elevated CO2 concentrations and indirect nitrogen deposition are considered
to be approximately the same in the FMRL and in the commitment period estimates, and they can therefore be
assumed to be factored out. For projected FMRLs, it is generally assumed that the removals resulting fromelevated CO2 concentrations above the pre-industrial level and indirect nitrogen deposition will be factored out
when subtracting the FMRL from net emissions or removals that occur during the commitment period (assumingthat both include or exclude these effects). Similarly, the dynamic effects of differing age-class structures acrossforests resulting from past activities and practices and natural disturbances are included in both the constructionof the FMRL and the estimation of net FM emissions during the reporting period and therefore they cancel out.

Continuity with the treatment of FM in the f irst commitment period
This is not a relevant element for most approaches used to calculate the FMRL. For one Party, continuity withthe treatment of FM in the first commitment period means that the same narrow approach with gross–net
accounting will continue, and the FMRL was therefore set as zero. In this case, the narrow approach accounts
for emissions and removals only from forest land where these activities, including thinning, are implemented orwhere any additional activity is to be implemented to enhance sustainable forest management in the future. In
doing this, the narrow approach provides continuity with the first commitment period.

Policies included
Following Decision 2/CMP.6, Parties were requested to include in their FMRL submissions a description ofdomestic policies adopted and implemented no later than December 2009 and to explain how these polices havebeen considered in the construction of the FMRL. Parties were also requested to confirm that the construction of
the FMRL does not include assumptions about changes to domestic policies adopted and implemented after
December 2009. The aim of this information is also to document policies and assumptions included in the FMRL
in relation to country-specific circumstances. A few Parties also clarified the effects of policies related to use of
biomass as a renewable source included in the calculation of their FMRLs.
Parties proposing historical FMRLs based on 1990 emissions do not take into account policies and measuressince that year.

2.7.5.2

M ETHODOLOGICAL CONSIS TENCY BETWEEN FMRL AND
REPORTING FOR FM DURING THE COMMITMEN T PERIOD

According to Decision 2/CMP.7, when accounting for Forest Management, Parties shall demonstrate
methodological consistency between the [FMRL] 97 and reporting for Forest Management during the second
commitment period… and …shall make technical corrections, if necessary, to ensure consistency, including
applying IPCC methods for ensuring time-series consistency... This section discusses general issues and goodpractice guidance related to methodological consistency. Technical Corrections are addressed in the following
section.
Consistency is a key principle in the estimation of GHG inventories. According to the 2006 IPCC Guidelines,
consistency means that an inventory should be internally consistent in all its elements over a period of years, i.e.
it refers to the need for time-series consistency of an inventory. An inventory is consistent if the same
methodologies are used for all years and if consistent data sets are used for estimating carbon stock changes andnon-CO2 GHG emissions during the whole period. Under certain circumstances98 an inventory using different
methodologies for different years can be considered to be consistent if it has been recalculated in a transparent
manner and if potential inconsistencies are minimized in accordance with the guidance provided in the 2006
IPCC Guidelines (Chapter 5, Volume 1) and with GPG-LULUCF (Chapter 5).
Chapter 5, Volume 1 of the 2006 IPCC Guidelines (Time series consistency) describes common situations inwhich time series consistency may not be achieved, including: 1) recalculations due to methodological changes
and refinements and 2) adding new categories. A methodological change is a switch to a different tier (or to adifferent method, e.g. from Stock-Difference to Gain-Loss, or from an inventory-based to a process-based
method) from the one previously used for reporting, often driven by the development of new and different data97

Chapter 2: Methods for estimation, measurement, monitoring and reporting

sets. A methodological refinement occurs when an inventory compiler uses the same tier to estimate emissions
but applies it using a different data source, a different model version or a different level of aggregation. Bothmethodological changes and refinements over time are an essential part of improving inventory quality. The
addition of new categories also includes the addition of new carbon pools and gases.
In the context of FMRL, methodological consistency refers to the need that during the commitment period
consistency is ensured between the methodological elements used in the construction of FMRL and those used in
the reporting of FM. To this end, it is good practice to consider all the specific elements highlighted inparagraphs 14 and 15 of the Annex to Decision 2/CMP.7. Specifically, the methodological elements include:(i)the method used to establish the FMRL, as reported in the FMRL submission (only for approach 1
in Box 2.7.3: projected FMRL): models or average/extrapolation of historical time series;(ii)

the historical data99 used to establish the FMRL, as reported in the FMRL submission: forest area,
harvest, increment, age structure, forest characteristics and management, net emissions and related
estimation parameters etc.;(iii)

other methodological elements used to establish the FMRL as reported in the FMRL submission,
including: pools and gases, the treatment of HWP, the treatment of natural disturbances, climate
and other ecological parameters used by models for projecting FMRL; and(iv)elements newly introduced or modified by Decision 2/CMP.7 as compared to the text in Decision
2/CMP.6, including: the accounting HWP removed from areas under FM (see Section 2.3.8) andthe possible exclusion of emissions associated with natural disturbances (see Section 2.3.9).

A change in methodological elements used in the construction of FMRL triggers a methodological inconsistency,
to be addressed through a Technical Correction (see section 2.7.6.1).
By contrast, for projected FMRL only, a deviation in policy assumptions under business-as-usual scenario (asreported in the FMRL submission) from those assumed in constructing the FMRL does not represent a
methodological inconsistency, and thus is not considered for Technical Correction. Specifically, policy
assumptions under business-as-usual scenarios include economic assumptions or responses (e.g. harvesting
decisions), and assumptions about future FM area, about future management of forest (including activities suchas fertilization and planting), about forest characteristics, about harvesting rates (including variations inharvesting rates as compared to historical period) or amounts, and about production of HWP (including
assumptions about the quantities of HWP produced in the major categories, i.e. sawn wood, panels, and paper).
In the event of change in FM area during the commitment period (e.g. if the narrow approach to FM is used), it
is good practice to document transparently that this is not a result of change in FM activity definition, but rather
a result of newly implemented policies that were not included in the FMRL submission. During the commitment
period, the country’s chosen definitions of “forest” and “Forest Management” need to be consistently applied
across the time series and need to be the same as the ones used for FMRL calculations.
A common situation of methodological inconsistency is change, after the FMRL has been set, of one or more of
the methodological elements used in its construction. For instance, a methodological change (e.g. from StockDifference to Gain-Loss) or refinement (e.g. updated data or model parameters) may lead to recalculation ofhistorical data used to establish FMRL, or treatment of HWP or natural disturbances may change in thecommitment period as compared to the FMRL. These changes would introduce methodological inconsistencies.
Other cases of inconsistency between the FMRL and reporting for FM during the commitment period are
possible. For this reason, for the purpose of demonstrating that the accounting of emissions and removals during
the commitment period is not affected by methodological or time-series inconsistency, additional information
and/or checks may be needed, depending on the approach and method used to set FMRL.
For projected FMRLs, it is good practice to provide information on the main factors generating the accounted
quantity (i.e. the difference in net emissions between reporting of FM during the second commitment period andthe FMRL). For instance, given that harvest rate is generally the main driver of forest carbon balance in the shortterm, it is good practice to show that, e.g. a higher (or lower) sink during the second commitment period, as
compared to what was assumed in the business-as-usual scenario, is quantitatively consistent with the observed
lower (or higher) harvest rate, and/or to provide evidence that other major factors are contributing to thedifference. It increases transparency to provide in the annual inventory submission concise information to
explain major drivers (e.g. harvesting rates) affecting the trend in net emissions under FM as compared to what
was assumed in the FMRL. The aim of this information is to show that the estimates reported in the second
commitment period can be explained in terms of deviations in policy assumptions or responses to them (e.g.
harvest rate) as compared to what was assumed in the FMRL. In addition, it is good practice to show that model99

Historical data refers to data for the time period used in the construction of the FMRL (including model parameters,
emission factors, etc.)2013 Revised Supplementary Methods and Good Practice Guidance Arising from the Kyoto Protocol

2.97

Chapter 2: Methods for estimation, measurement, monitoring and reporting

based calculations used for constructing a projected FMRL reproduce the data for FM or Forest Land Remaining
Forest Land for the historical period reported in the FMRL submission (i.e. for the period not affected bypossible deviations from policy assumptions under the business-as-usual scenario). It is also good practice toprovide documentation fulfilling the general criteria listed in Annex I of the Use of Models and Facility-level
Data in Greenhouse Gas Inventories: Report of the IPCC Expert Meeting on the Use of Models andMeasurements in GHG Inventories (IPCC, 2010d), including information on model selection and development,
on model calibration and evaluation, on input data used, on uncertainties, on model implementation and on theevaluation of model results.
According to Decision 2/CMP.7, a Party may choose not to account for a given pool in a commitment period(with the exception of HWP) if transparent and verifiable information is provided that demonstrates that the pool
is not a source. However, for any of the approaches used to set FMRL, once a pool has been included in the
FMRL inscribed in the Appendix to Decision 2/CMP.7, for consistency reasons this pool is required to bereported and accounted for also during the commitment period, irrespective of the pool being a sink or a source.

2.7.6

Technical Corrections for accounting purposes

Estimation of the FMRL typically relies upon data inputs, assumptions, and models brought together in aconsistent and transparent way. For accounting of FM, what counts is the difference in emissions and removals
between the FMRL and the actual FM emissions and removals in the second commitment period. It is therefore
important to ensure that the FMRL and reporting of FM during the commitment period are as methodologicallyconsistent as possible (see Section 2.7.5.2).
If the reported data on FM or Forest Land Remaining Forest Land used to establish the reference level are
subject to recalculations, or if other methodological inconsistency exists between the FMRL and FM reporting
during the commitment period, to ensure consistency, Parties are required100 to apply a Technical Correction.
The Technical Correction removes the impact of any methodological inconsistency when accounting and thus
ensures methodological consistency between the FMRL and the reporting of FM during the commitment period.
The Technical Correction is essentially a net value of emissions and removals, added at the time of accounting tothe original FMRL (contained in Decision 2/CMP.7) to ensure that accounted emissions and removals will notreflect the impact of methodological inconsistencies, as expressed in Equation 2.7.1 (in Mt CO2eq yr-1):
EQUATION 2.7.1
TECHNICAL CORRECTION
Technical _ Correction  FMRLcorr  FMRL
Where:FMRL = Forest Management Reference Level inscribed in Appendix to Decision 2/CMP.7
FMRLcorr = Forest Management Reference Level recalculated for the purpose of calculating theTechnical Correction
FMRL itself is not changed through a Technical Correction. However, when the need for Technical Correction is
identified, i.e. if a methodological inconsistency is found at any time during the commitment period, theFMRLcorr represents the recalculated reference level that is not affected by any methodological inconsistencies.
This section describes how to detect the need for Technical Correction, how to calculate FMRLcorr, and when to
apply the Technical Correction.

Chapter 2: Methods for estimation, measurement, monitoring and reporting

The need for Technical Correction may arise only if at least one of the following conditions is met (see Table
2.7.1 for a full list of criteria and elements to be checked, and examples in Box 2.7.4):
1.

The method used for GHG reporting changed after the adoption of FMRL, or errors in the methods havebeen identified, as part of improving inventory quality. For instance, in the future, new methods may be
developed that take advantage of new datasets and modelling tools, new technologies, or improved scientificunderstanding. For example, remote-sensing technology and site-specific modelling are making it feasible toestimate historic emissions from land clearing activities more accurately than by using simple aggregate
emission factors and activity data. The development of new or refined inventory methods for reporting ispart of the broader process of continuous improvement, which countries are encouraged to follow.
This change will lead to a recalculated time series that might also lead to an inconsistency between FMRL
and reporting of FM in the second commitment period.

2.

Any of the following methodological elements used to establish the FMRL (as reported in the FMRL
submission) changed after the adoption of FMRL:(i)

New carbon pools or non-CO2 GHG sources are included in reporting for FM in the second
commitment period. For instance, if a pool that was not a source and therefore not reported earlier (andalso not included in the FMRL) becomes a source in future, it is good practice to include this pool in thereporting of FM, applying a Technical Correction.

(ii) Recalculated historical data. For example, forest inventory data may be compiled only once in a five- or
ten-year period. In the event that recalculated historical forest inventory data (e.g. new area, age
structure, carbon stock, net removals, harvest, or increment rates) become available that could not be
used for the construction of the FMRL, and these new data are used in GHG reporting in the second
commitment period, a Technical Correction would allow the inclusion of such new information in the
FMRLcorr.
In the case of FMRLs based only on elaboration of historical data from GHG inventories (average ofpast data, linear extrapolation) or FMRLs based on the single year 1990, any recalculation of the timeseries used to establish the FMRL will trigger a Technical Correction.
(iii) In the event that the FMRL was constructed using models that are responsive to climate variability, if
climate data observed during the commitment period is different from that assumed by the models used
to construct FMRL, then a Technical Correction would allow application of actual climate data to themodels (see also Section 2.3.5 on interannual variability).
(iv) Treatment of elements newly introduced or modified by Decision 2/CMP.7:

3.

-

The accounting of HWP as agreed in Decision 2/CMP.7: since FMRLs were submitted before
Decision 2/CMP.7, a Technical Correction related to HWP is expected to be a common case.

-

The application of natural disturbances provision in Decision 2/CMP.7: since FMRLs were
submitted before Decision 2/CMP.7, they may be inconsistent with the agreed provisions,
including those specifying that the expectation of neither credits nor debits is to arise fromapplication of the disturbance provisions. For instance, if the background level as established by
the Party requires exclusion of emissions from the projected FMRL (either due to thebackground level and margin selected, or because the emissions are outliers), it is good practice
to remove these emissions, to calculate FMRLcorr and to apply a Technical Correction. Using themethods set out in Section 2.3.9 (on natural disturbances), it is good practice that the Parties
provide information in NIRs on how the Technical Correction for changes in the treatment ofemissions from natural disturbances was calculated.

Other kinds of methodological inconsistency. For example, if a model used for constructing a projected
FMRL does not reproduce the data for the historical period reported in the FMRL submission for FM or
Forest Land remaining Forest Land, this is a sign of likely inconsistency. In this case, it is good practiceeither to provide additional evidence demonstrating consistency or to apply a Technical Correction.

If needed, calculate FMRLcorr, e.g. byapplying IPCC methods to ensure timeseries consistency* For each of the methodological elements, “historical data” refers to data for the time period used in the construction of the FMRL
(including model parameters, emission factors, etc.).

For projected FMRLs, deviations from policy assumptions under business-as-usual scenarios, including
economic assumptions or responses (e.g. harvesting decisions), and assumptions about future FM area, about
future management of forest, about forest characteristics, about harvesting rates or amounts, and about
production of HWP (including assumptions about the quantities of HWP produced in the major categories) do
not affect methodological consistency and thus are not considered for Technical Corrections (see Section 2.7.5.2).
Under Decision 2/CMP.7103, Parties may account for emissions by sources and removals by sinks resulting fromthe harvest and conversion of a forest plantation to non-forest land under FM, provided that a forest of at least
the same area and carbon stock potential is established on non-forest land, and provided that all otherrequirements are satisfied (CEFC, see Section 2.7.7). Given that emissions and removals from plantation
harvesting and replanting or equivalent forest establishment are already included in the FMRL, and that theeffects of implementing CEFC will be accounted for against the FMRL (see Section 2.7.7), the decision to apply
the CEFC provision does not in itself trigger a Technical Correction. A methodological inconsistency between
reporting of FM in the second commitment period and the FMRL included in the Annex to Decision 2/CMP.7(including methods to estimate emissions and removals from lands subject to the CEFC provision) will trigger aTechnical Correction.

Note that, when accounting, it is not possible to exclude a pool or gas already included in the FMRL.

EXAMPLES OF CASES WHICH MAY LEAD TO METHODOLOGICAL INCONSISTENCY BETWEEN FMRL AND
REPORTING OF FM DURING THE SECOND COMMITMENT PERIOD.
Case 1:At the time of FMRL submission:-The GHG inventory used Stock-Difference or Gain-Loss method (i.e. not a model).
-The FMRL was constructed using model X.
Can this country apply a different method in GHG reporting during the second commitment period?
Yes, but this will create a methodological inconsistency, which triggers a Technical Correction process.
Can this country apply model X (same version used for FMRL) in GHG reporting?
Yes, this will ensure consistency between the methods used for FMRL and FM reporting. However, it is always
good practice to check the need for Technical Correction (Figure 2.7.3).
Can this country apply a new model Y (or a new version of model X) in GHG reporting?
Yes, but this will create a methodological inconsistency, which needs to be addressed through the TechnicalCorrection process. In this case, a possible way to address the inconsistency is using the new model Y (or a newversion of the model X) also for calculating FMRLcorr as part of the Technical Correction process.
Case 2:At the time of FMRL submission:- The GHG inventory used model X.
- FMRL was constructed using model X.
Can this country use a new model Y (or a new version of model X) in GHG reporting?
Yes, but this will create a methodological inconsistency, which may be addressed by using the new model Y (ornew version of the model X) also for calculating FMRLcorr as part of the Technical Correction process.
Case 3:At the time of FMRL submission:-

The GHG inventory used data from NFIs representing the years 1995 and 2005.

-

FMRL was modelled using historical input data for the period 2000-2009, where data for 2000-2005 werebased on the two NFIs and those for 2006-2009 were extrapolated using existing NFI data.

In 2012, a new NFI was finalised resulting in recalculation of data for the period 2006-2009. This triggers arecalculation of the GHG inventory, and consequently a Technical Correction has to be applied. The new timeseries for 2000-2009 including historical data for 2000-2005 and recalculated historical data for 2006-2009 areused for calculating FMRLcorr. The same approach would apply in the case where, at the time of FMRL
submission, the GHG inventory and the FMRL used preliminary data from an on-going NFI (e.g. to be completed
after the FMRL submission). In this case, when the NFI is completed, the historical data used in FMRL
construction are recalculated and consequently a Technical Correction has to be applied using the recalculated
historical data for calculating FMRLcorr. In both cases, only the data representing the same years as the data used
to calculate the initial FMRL shall be used to calculate FMRLcorr.
Case 4:At the time of FMRL submission, the FMRL submission included emissions from natural disturbances. In the2015 NIR, the background level (and the margin if relevant, see Section 2.3.9) were set to zero. In this case, it isgood practice for zero emissions to be factored in the FMRL and for all emissions from natural disturbances to be
excluded. This requires a Technical Correction to the FMRL.

2.7.6.2 H OW TO PERFORM AND DO CUMENT THE CALCULATI ON OF
FMRL C O R R
If the need for Technical Correction is determined, it is good practice to calculate FMRLcorr. Several methods
may be considered to address methodological inconsistencies and to calculate FMRLcorr, depending on theapproach used to construct FMRL, the cause of the inconsistency, and the data that are available to perform therecalculations. Irrespective of the method used, it is good practice to provide information that the method used

2.102

2013 Revised Supplementary Methods and Good Practice Guidance Arising from the Kyoto Protocol

Chapter 2: Methods for estimation, measurement, monitoring and reporting

avoids the expectation of net credits and net debits linked to any methodological inconsistency between
FMRLcorr and reporting for FM during the commitment period.
In the case of projected FMRLs, FMRLcorr may be calculated by, inter alia, a new model-based projection using
new historical data or applying a different treatment of a specific element (e.g. HWP, natural disturbances).
When new projections are made, it is essential to keep all policy assumptions under the business-as-usual
scenario (as reported in the FMRL submission) unchanged. It is also good practice to show that the new modelbased calculations used for constructing FMRLcorr are capable of reproducing the data for FM or Forest Land
Remaining Forest Land for the historical period reported in the FMRL submission (i.e. for the period notaffected by possible deviations from policy assumptions under the business-as-usual scenario), or to provide any
explanation if this is not the case.
If the need for a Technical Correction due to a methodological inconsistency has been identified, but a newmodel run cannot be performed, time-series consistency can be ensured by using one of the methods described in
the 2006 IPCC Guidelines, including overlap between model results and data for FM of Forest Land Remaining
Forest Land reported for the historical period (before the FMRL submission). In this case, consistency would beensured ex-post, i.e. adjusting existing model results to the historical reported data.
It is essential that the criteria to calculate FMRLcorr are the same as those used for setting FMRL, i.e. if the
FMRL is calculated as a linear extrapolation of any historical period trend, it is good practice to use the same
period for FMRLcorr in case a recalculation of historical time series occurs. This is because, for the FMRL
submission, the period selected was assumed as a proxy for a business-as-usual scenario, and changing theperiod would mean changing the policy assumptions. In the case of FMRL based on elaboration of historical
data only, (average of past data, linear extrapolation) or on the single year 1990, any recalculation of the timeseries will automatically produce FMRLcorr.
Irrespective of the method applied to calculate FMRLcorr, it is good practice to complement any TechnicalCorrection with transparent information on:

the rationale for calculating FMRLcorr (description of which criteria in Table 2.7.1 have been met);the methods used to calculate FMRLcorr; in case a model is used, it is good practice to document theimplementation of the model following the criteria listed in Annex I of IPCC (2010d); and

results (i.e. the FMRLcorr) and discussion of the differences between FMRLcorr and FMRL; for this purpose,
it is good practice to report a comparison of recalculated estimates with previous estimates, e.g. as shown in
Table 2.7.2 and if possible also as a graphical plot showing the temporal dynamics of the estimates
underlying FMRLcorr and FMRL.

information on this in the annual NIR.

Carbon Equivalent Forests

2.7.7.1

D EFINITIONAL ISSUES A ND REPORTING REQUIREMENTS

Under Decision 2/CMP.7, Parties may account for emissions by sources and removals by sinks resulting fromthe harvest and conversion of some forest plantations to non-forest land under FM, provided that certain
requirements are met. The main requirement is that a new forest of at least equal area and carbon stock potential(including soil carbon) is created on non-forest land. Carbon Equivalent Forest Conversion (CEFC) is thepractice of converting a forest plantation to non-forest land while establishing a “Carbon Equivalent Forest” on
non-forest land elsewhere.
CEFC requires two land components – the existing forest land to be harvested and converted to non-forest land
(CEF-hc) and the non-forest land on which a forest is to be newly established (CEF-ne). Both components shallmeet the criteria for CEFC set out in Decision 2/CMP.7105 in order to be accounted for under FM. The forest
cleared is required to be a forest plantation as defined in Annex 4A.1 of the 2006 IPCC Guidelines, and both thisand the new forest established have to meet the definition of forest as selected by the Party and used forreporting other FM lands. It is good practice for Parties to provide, according to their national circumstances,the definition of forest plantation that is used in the application of the CEFC provision. This definition needs tobe consistent throughout the time series and the inventory.
Decision trees for categorising forest harvest and conversion (Figure 2.6.1) and forest establishment (Figure
2.5.1) are provided in Sections 2.5 (Afforestation and Reforestation) and 2.6 (Deforestation), respectively.
Criteria for eligibility under the CEFC provision are described in Section 2.7.7.2.
In accordance with Decision 2/CMP.7 all lands and associated carbon pools subject to the CEFC provision
shall be identified, monitored and reported, including the georeferenced location and year of conversion.
Accounting for FM lands is with respect to the FMRL, so pools need to be consistent with the pools included
within the FMRL, including HWP. Section 2.2 (Generic methodologies for area identification, stratification andreporting) describes two Reporting Methods that can be used to define and report the geographical location ofland areas subject to FM activities. Reporting Method 1 can only meet the CEFC reporting requirements if
additional, georeferenced information about specific land areas within the geographic boundaries is provided.
This additional information could be reported using a time series of maps or data sets containing thegeoreferenced information about the location of these lands. The year of conversion will be between 1 January
2013 and the end of the last inventory year. For practical reasons harvesting, conversion to a non-forest land use
and new forest establishment may occur in different years within the commitment period. The year of CEFC
conversion is taken as the year in which land-use change on CEF-hc land is confirmed or the year in which newforest is established on CEF-ne land, whichever is earliest within the commitment period.
It is good practice for the Party to also provide:the area of lands subject to CEFC activity in each productivity class and species combination (where
relevant) to support the calculation of carbon stock changes and non-CO2 GHG emissions;documentation that demonstrates the relationship between forest land harvested and converted and thecorresponding land established in forest under the CEFC provision;the normal harvesting cycle (in years) and the carbon stock at the time of harvest of each unit of CEF-hc
land; if the FMRL is based on a business as usual projection then it is good practice that the normal
harvesting cycle is used as it was assumed in the FMRL; andinformation to demonstrate that the new forest established has the potential to reach a carbon stock no lessthan the stock that was contained in the harvested forest plantation it replaces at the time of harvest, within
the normal harvesting cycle of the harvested forest plantation.

The carbon stock at harvest and the normal harvesting cycle of the forest plantation harvested and converted
provide the targets for the new forest established on CEF-ne land. It is good practice to monitor progress of the
CEF-ne land towards achieving carbon equivalence by reporting the current area, age and estimated carbon stockin each inventory year. This needs to be reported until the carbon stock in the original forest plantation has been
met or exceeded.

2.7.7.2

C HOICE OF METHODS FOR IDENTIFYING LANDS SU BJECTTO C ARBON E QUIVALENT F OREST C ONVERSION

For eligibility under the CEFC provision, conditions apply to both the land converted from forest plantation to
non-forest (CEF-hc) land and the corresponding land converted from non-forest to forest (CEF-ne land). The
requirements of Decision 2/CMP.7 for a forest plantation to be harvested and converted under the CEFC
provisions (CEF-hc) are as follows:

The forest plantation meets the requirements for the country’s definition of forest as well as their specificdefinition of forest plantation at the time of conversion.

The forest plantation existed on 31 December 1989.



The forest plantation had been first established by direct human-induced planting and/or seeding.

The forest plantation had first been established on non-forest land. If this non-forest land was previously
forested (that is to say it had been converted from forest to another land use), it is good practice to apply thesame criteria as those used to distinguish D from harvesting or forest disturbance that is followed by the reestablishment of a forest (see Section 2.6.2.1). For example, if normal practice in a country is to re-establish
forests within three years after harvesting, then a forest plantation that was first established on land that hadremained non-forest for more than three years would normally be eligible under the CEFC provision.

The forest plantation is still the original forest first established on non-forest land before 1 January 1990, or,if re-established after harvesting, this last occurred through direct human-induced planting and/or seeding
after 1 January 1960.

It is good practice to apply the methods described in Section 2.6.2 for identifying lands subject to direct humaninduced D to also identify lands cleared of forest which may be accounted for under the CEFC provision, since
only land that would otherwise qualify as D land will qualify as CEF-hc land.
The decision tree for determining eligibility for forest land to be converted to non-forest land under the CEFC
provision is shown in Figure 2.7.4.

The land did not contain forest at the time of conversion.

The land did not contain forest on 31 December 1989.

The land has been converted to forest land through direct human-induced planting and/or seeding.

The forest established is at least equal in area to the forest plantation converted to non-forest.



The forest established is shown to have the potential to reach a carbon stock no less than the stock that was
contained in the harvested forest plantation it replaces at the time of harvest, within the normal harvesting
cycle of the harvested forest plantation.

It is good practice to apply the methods described in Section 2.5.2 for identifying lands subject to direct humaninduced AR, also for identifying lands established in forest which may be accounted for under the CEFC
provision, since only land that would otherwise qualify as AR land will qualify as CEF-ne land.
The decision tree for determining eligibility for non-forest land to be converted to forest land under the CEFC
provision is shown in Figure 2.7.5.

All lands and associated carbon pools subject to the CEFC provision should be accounted under FM. This
includes any HWP resulting from the conversion of forest to non-forest land under the CEFC provision.
It is good practice to provide documentation that the CEF-ne lands identified are forests established by direct
human-induced planting and/or seeding.

DISCRIMINATING BETWE EN ARD LAND AND CARB ON EQUIVALENTFOREST CONVERSION LA ND
Both CEF-hc and CEF-ne lands are reported as part of FM lands from the time of conversion, and any doublecounting with AR and D land needs to be avoided. Documentation should be provided to demonstrate that all therequirements for the CEFC provision have been met and that there is no double-counting of emissions or
removals.
If CEF-ne land is deforested during the commitment period before reaching the country-specific thresholds fordefining forest, both this and associated CEF-hc land need to be reclassified under D. Emissions associated withharvesting and conversion of the CEF-hc land should be included under D. Any removals occurring on CEF-ne
land before the deforestation event should be accounted for under AR. If D of CEF-ne land takes place after theforest thresholds are reached, only the CEF-ne land needs to be classified as D land.

It is a requirement under Decision 2/CMP.7 that areas subject to the CEFC provision are reported under FM thathas priority over elected activities under Article 3.4 (see Section 1.2). This means that there may be lands thatare subject to elective Article 3.4 activities (e.g. CM) but are reported under FM. It is good practice to identify
and report these lands separately from other FM lands. Methodologies appropriate to the actual land use can beapplied to ensure that emissions and removals are neither under- nor over-estimated. It is good practice toprovide documentation to show how double counting of emissions and removals has been avoided.

2.7.7.3

C HOICE OF METHODS FOR ESTIMATING CARBON ST OCKCHANGES AND NON -CO 2 GHG EMISSIONS

It is good practice to apply the same methods for estimating carbon stock changes and non-CO2 GHG emissionson CEF-ne lands as are applied on AR lands, described in Section 2.5.3. Estimation and reporting for these lands
begin from the year of conversion, which may be before the new forest is established but in any event will bewithin the commitment period. Methods that apply for harvesting on FM lands are appropriate for CEF-hc lands,
because stock changes will be captured in all pools, including HWP. In both cases, it is good practice to use thesame or a higher tier. In addition, forest land converted to non-forest under the CEFC provision may be subject
to management that results in carbon stock changes and non-CO2 GHG emissions over-and-above what would
have been expected if the forest had been re-established. It is good practice to capture these emissions andremovals by applying the methods for the appropriate land use (e.g. Cropland or Grassland) found in the 2006
IPCC Guidelines.
Accounting for FM is based on the reference level approach (FMRL), as described in Section 2.7.5. The basis fordetermining accounting credits or debits in the commitment period is a comparison of actual emissions andremovals in FM, including any emissions and removals in CEF-hc and CEF-ne lands combined, with the FMRL.
If forest land established under the CEFC provision is affected by natural disturbance, emissions and subsequent
uptake on that land can be excluded from accounting in accordance with the natural disturbance provisions in
Section 2.3.9. The natural disturbance accounting provisions apply to emissions from forests and therefore
cannot be used for natural disturbances affecting non-forest CEF-hc land even though these lands are accounted
for under FM.

2.8

HARVESTED WOOD PRODUCTS (HWP)

Section 2.8 provides good practice guidance for estimating annual changes in carbon stocks and associated CO2
emissions and removals from the Harvested Wood Products (HWP) pool (hereinafter referred to as the HWP
contribution) to be reported and accounted for in accordance with Decision 2/CMP.7 and 2/CMP.8.106 It provides
guidance for selecting adequate data and methods consistent with the system boundaries of the accounting
approach defined in the Decision.
Various approaches have been proposed for estimating and reporting the HWP contribution. They differ in thereference to the atmosphere and the treatment of HWP trade, due to different interpretations of some key terms
that are relevant for the reporting framework (Winjum et al., 1998, Cowie et al., 2006). This situation is reflected
in Chapter 12, Volume 4 of the 2006 IPCC Guidelines which states that the guidance given “does not prefer anyof these [approaches] and does not attempt to prejudge whether these, or any other approach, should be used toaccount” for the HWP contribution (IPCC 2006). Hence, it suggests calculating different variables that areneeded to estimate the HWP contribution according to the different approaches (see Table 12.1, Chapter 12,
Volume 4 of the 2006 IPCC Guidelines).
One of the implications of Decision 2/CMP.7 is that accounting of HWP is confined to products in use where thewood was derived from domestic harvest, i.e. trees harvested in the reporting country.107 In principle, this issimilar to basing estimates of the HWP contribution on changes in the pool (i.e. stock-changes) reflected byvariable 2A in Table 12.1, Chapter 12, Volume 4 of the 2006 IPCC Guidelines, however Decision 2/CMP.7
imposes some additional constraints and limits the extent of HWP which can be included in the estimates.

2.8.1

Initial steps to estimate the HWP contribution

To estimate the HWP contribution and account for the changes in the HWP pool in line with Decision 2/CMP.7,
it is good practice to follow the decision tree (Figure 2.8.1) and the steps described below.

STEP 1:
Check the construction of the forest management reference level(FMRL) and the availability of transparent and verifiable activity data on HWP
According to Decision 2/CMP.7 Parties are required to account for HWP on the basis of the change in the HWPpool during the second and subsequent commitment periods, provided that transparent and verifiable activity
data are available for the three HWP categories, sawn wood, wood panels and paper.108 In the case that thecountry’s FMRL is based on a projection, accounting shall be on the basis of the change in the HWP pool (i.e.
Tier 2 or 3 methods).109 In order to meet the requirements of Decision 2/CMP.7 countries should:
STEP 1.1: Check whether the FMRL has been based on a projection (see 2.7.5). If this is the case, skip thenext steps and go to STEP 1.4.
STEP 1.2: Check databases of international organizations, such as the public database of the Food andAgriculture Organization of the United Nations (FAO)110 for the availability of production and trade statistics on
the HWP categories defined in Decision 2/CMP.7. Detailed guidance is given in Section 2.8.1.1.
STEP 1.3: Check whether other activity data (i.e. country-specific) are available which fulfil the requirement
to be transparent and verifiable. Further guidance is given in Section 2.8.4.1. In the case that data from STEP 1.2
and/or 1.3 are available go to STEP 1.4, otherwise apply Tier 1 (Section 2.8.2).
STEP 1.4: Ensure that HWP data represent information on the material use of wood (products in service) inorder to exclude the HWP used for energy purposes and HWP in solid waste disposal sites (SWDS)111 and crosscheck the information with guidance given in Sections 2.8.1.1 and 2.8.4.1. If activity data represent information
on material use of HWP in service go to STEP 2, otherwise apply Tier 1 (Section 2.8.2).

Chapter 2: Methods for estimation, measurement, monitoring and reporting

STEP 2: Check whether HWP categories originate from forests that are
accounted for by the country and allocate HWP to the particular forest related
activity
Decision 2/CMP.7 limits the mandatory accounting to HWP originating from domestic forests which areaccounted for under Article 3, paragraphs 3 and 4. Imported HWP, irrespective of their origin, are excluded112.
Figure 2.8.1 shows that Decision 2/CMP.7 specifies the methods to be used for the estimation of the HWP
contribution depending on the land of origin of HWP.113
Detailed guidance on how to implement all the following steps is given in Section 2.8.1.2.
STEP 2.1: Estimate the share of HWP originating from forests within the country. The default assumption isthat domestically consumed industrial roundwood represents the domestic production feedstock for thesubsequent processing of the semi-finished product categories sawnwood and wood panels. Domesticallyconsumed wood pulp is the feedstock for paper production.
STEP 2.2: Estimate the share of HWP originating from Afforestation (A), Reforestation (R) andDeforestation (D) under Article 3 paragraph 3 and Forest Management (FM) under Article 3 paragraph 4 as themethods for estimating the HWP contribution will differ according to the provisions outlined in the decision tree
for tier selection (Figure 2.8.1).
STEP 2.3: The amount of HWP entering the accounting framework (i.e. activity data) is obtained by
combining the information from STEPS 2.1 and 2.2 with the annual production of the HWP commodity
categories obtained from STEP 1.

STEP 3: Check the availability of country -specific information and estimate
carbon stock in HWP and its annual change
Depending on the results of STEPS 1 and 2, and on the availability of country-specific half-lives and/or countryspecific methodologies, the estimation of the HWP contribution follows different tier methods.
Tier 1 method specifies the assumption of instantaneous oxidation and is to be used under certain circumstancesand for specific parts of the HWP pool as explained further down below. The combination of HWP activity data
following the international classification system of semi-finished wood products (Figure 2.8.2) with default
conversion factors and default half-lives constitutes Tier 2. Under a Tier 3 method, more accurate countryspecific information is applied. This includes activity data and/or emission factors (i.e. service life information of
HWP), which is intended to improve the accuracy of the estimates. In order to choose the appropriate tiermethod, please follow all the steps presented below.
STEP

3.1: In case HWP originate from Deforestation (D) use Tier 1 method (Section 2.8.2).

STEP 3.2: Check whether country-specific HWP activity data following the international classification
system outlined in Section 2.8.1.1 together with specific conversion factors are available for the country
following the guidance given in Section 2.8.4.1. If this is the case, allocate HWP activity data in line with STEP
2 and apply Tier 3 (Section 2.8.4).
STEP 3.3: Check whether country-specific half-life values for the three HWP categories and/or theirdisaggregates (see Section 2.8.1.1) can be obtained following the guidance given in Section 2.8.4.2. If this is thecase, apply Tier 3 (Section 2.8.4).
STEP 3.4: Check whether other country-specific methods are available that meet the requirements as
specified in Section 2.8.1.1 and 2.8.4. If this is the case, allocate HWP activity data in line with STEP 2 andapply Tier 3 (Section 2.8.4).
STEP 3.5: In case the country is unable to apply a Tier 3 method as outlined for the STEPS 3.2 to 3.4,
allocate HWP activity data in line with STEP 2 and apply Tier 2. Guidance on Tier 2 is given in Section 2.8.3.

2.8.1.1

A VAILABILITY OF TRANSPARENT AND VERIFIABLE
ACTIVITY DATA

A prerequisite for Parties when accounting for HWP on the basis of the change in the HWP pool is theavailability of “transparent and verifiable activity data” for the three specified HWP categories “paper, […]112

2.111Chapter 2: Methods for estimation, measurement, monitoring and reportingwood panels, and […] sawnwood” (see STEP 1).114 This section provides guidance on when available data is tobe considered transparent and verifiable for estimating the HWP contribution.
Whereas the term “harvested wood products” is based on a concept containing the two separate elements “forest
harvesting” and “wood products” (Brown et al., 1998, UNFCCC Secretariat 2003), the categories named in
Decision 2/CMP.7 refer to the definitions of semi-finished wood products of the international classification
system of forest products.115 It is thus good practice to assume that the three HWP categories named in Decision
2/CMP.7 accord with these commodities. Other terms commonly used include “removals” (i.e. roundwood) are asubset of “forest harvesting” of biomass (i.e. fellings) at the beginning of the forest-wood chain (see definitions
below). Following the forest products definitions of the FAO, Figure 2.8.2 furthermore shows the relevance of
the aggregate commodity “industrial roundwood”. Its subcategories provide the feedstock for the subsequent
processing of the three named semi-finished HWP commodities along the value chain (cf. FAO 2012). Theinternational classification system for forest products can be related to the Harmonized Commodity Description
and Coding System (HS) of tariff nomenclature provided by the World Customs Organization (WCO).116

drawn from the definitions of the Joint Forest Sector Questionnaire (JFSQ) as established by the Intersecretariat
Working Group on Forest Sector Statistics117 and form the basis for the forest products statistics e.g. provided by
FAO. The JFSQ also includes conversion factors to be used for converting e.g. from nominal to solid volume inthe compilation of statistics if required.115 Datasets for these aggregate product categories are freely and easily
accessible, are updated on at least an annual basis with a 6-month or one year reporting lag, and time series areavailable for most countries worldwide.118
SAWNWOOD (Decision 2/CMP.7 refers to this as “sawn wood”): “Wood that has been produced from both
domestic and imported roundwood, either by sawing lengthways or by a profile-chipping process and thatexceeds 6 mm in thickness. It includes planks, beams, joists, boards, rafters, scantlings, laths, boxboards and"lumber", etc., in the following forms: unplaned, planed, end-jointed, etc. It excludes sleepers, wooden flooring,mouldings (sawnwood continuously shaped along any of its edges or faces, like tongued, grooved, rebated, Vjointed, beaded, moulded, rounded or the like) and sawnwood produced by resawing previously sawn pieces. It
is reported in cubic metres solid volume.”115

WOOD-BASED PANELS (Decision 2/CMP.7 refers to this as “wood panels”): “This product category is anaggregate comprising veneer sheets, plywood, particle board, and fibreboard. It is reported in cubic metres solid
volume.”115 For the definitions of these subcategories please see FAO.
PAPER AND PAPERBOARD (Decision 2/CMP.7 refers to this as “paper”): “The paper and paperboard category is
an aggregate category. In the production and trade statistics, it represents the sum of graphic papers; sanitary andhousehold papers; packaging materials and other paper and paperboard. It excludes manufactured paper products
such as boxes, cartons, books and magazines, etc. It is reported in metric tonnes.”115
By definition, these three aggregate commodities of semi-finished wood products represent information on thematerial use of HWP and equal the default categories mentioned in Decision 2/CMP.7. All datasets are reported
in cubic metres solid volume or metric tonnes, which is information that enables countries to convert the data
given into carbon units. Commodities which are excluded from the definitions above (e.g. V-jointed sawnwood
or laminated veneer lumber (LVL)) may be the result of subsequent processing and therefore fall under the
category of finished wood products as illustrated in Figure 2.8.3. This also applies e.g. to wooden flooring that is
produced from sawnwood and/or hardboard which belongs to the category of wood-based panels; wooden
flooring in this case is therefore implicitly covered by the semi-finished HWP categories sawnwood and woodbased panels and included in the estimates for the HWP contribution. Thus, using statistical data both forsawnwood and for wooden flooring would result in double counting.

To avoid potential double counting, countries are encouraged to consult e.g. FAO for further clarification on themass flows along the forest wood processing chain depending on the classification and definition of the relevant
commodities.115 The inclusion of the commodity wood pulp under the HWP category “paper” would for example
result in double counting, as wood pulp by definition constitutes the feedstock for the production of paper andpaperboard (cf. definition below and Figure 2.8.2). The application of information on wood pulp does, however,enter the default method to calculate the share of HWP coming from domestic forests as reflected in Equation
2.8.2. Wood pulp data may also be used in higher tier methods provided that the country can demonstratetransparently that double counting is avoided (see Section 2.8.4.1).
In order to implement STEP 2 (see Section 2.8.1), further information is needed on commodities representing the
raw materials eventually used as feedstock for the production of the semi-finished HWP categories listed above(cf. Figure 2.8.2). Some possible feedstock commodities are not included in the default method to allocate HWP
to domestic forest activities as described in Section 2.8.1.2 below, due to difficulties in determining sources andmultiple uses, e.g. wood chips used in wood-based panel and wood pulp production as some chips come fromindustry co-products, others could be recycled products and others go to energy use (see Figure 2.8.3).
Definitions of some key feedstocks used are provided below.
According to the 2006 IPCC Guidelines, “WOOD-REMOVALS are generally a subset of fellings”.
ROUNDWOOD: “All roundwood felled or otherwise harvested and removed. It comprises all wood obtained fromremovals, i.e. the quantities removed from forests and from trees outside the forest, including wood recoveredfrom natural, felling and logging losses during the period, calendar year or forest year. It includes all wood
removed with or without bark, including wood removed in its round form, or split, roughly squared or in otherform (e.g. branches, roots, stumps and burls (where these are harvested) and wood that is roughly shaped or2013 Revised Supplementary Methods and Good Practice Guidance Arising from the Kyoto Protocol

pointed. It is an aggregate comprising wood fuel, including wood for charcoal and industrial roundwood (woodin the rough). It is reported in cubic metres solid volume underbark (i.e. excluding bark).” 115
INDUSTRIAL ROUNDWOOD (WOOD IN THE ROUGH): “All roundwood except wood fuel. In production, it is anaggregate comprising sawlogs and veneer logs; pulpwood, round and split; and other industrial roundwood. It isreported in cubic metres solid volume underbark (i.e. excluding bark). The customs classification systems usedby most countries do not allow the division of Industrial Roundwood trade statistics into the different end-use
categories that have long been recognized in production statistics (i.e. sawlogs and veneer logs, pulpwood andother industrial roundwood). Thus, these components do not appear in trade. It excludes: telephone poles.”115
WOOD PULP: “Fibrous material prepared from pulpwood, wood chips, particles or residues by mechanical and/or
chemical process for further manufacture into paper, paperboard, fibreboard or other cellulose products. It is anaggregate comprising mechanical wood pulp; semi-chemical wood pulp; chemical wood pulp; and dissolving
wood pulp.”115
Production data on finished wood products processed from the three semi-finished product categories (see Figure
2.8.2) are not included in international databases. However, the WCO HS tariff nomenclature (see above) also
includes some commodities for finished HWP (e.g. furniture, builders' joinery and carpentry of wood).
Accordingly, information on such commodities could be available in national production and trade statistics (seeSection 2.8.4.1). Consequently, good practice in providing transparent and verifiable activity data for HWP,
which qualifies for the provision of Decision 2/CMP.7 to account for the HWP contribution on the basis ofchanges in the HWP pool, is achieved by the availability of data for the three aggregate HWP commodities
sawnwood, wood-based panels and paper and paperboard in publicly available databases of internationalorganizations, such as FAOSTAT (cf. IPCC 2006 Guidelines). It is good practice to report on uncertainties
related to these datasets (see Section 2.8.6).
In addition, countries with available data on finished wood products produced from the default HWP categories
are encouraged to use these data following the guidance given in Section 2.8.4.

2.8.1.2

A LLOCATION OF HWP TO DOMESTIC FOREST A CTIVITIESUNDER A RTICLE 3, PARAGRAPHS 3 AND 4

According to Decision 2/CMP.7, accounting for the HWP contribution is restricted to carbon in HWP fromforests which are accounted for by the particular Party under Article 3, paragraphs 3 and 4. Carbon in imported
HWP is to be excluded. 119 As the accounting framework differentiates between activities under Article 3
paragraph 3 and activities under Article 3 paragraph 4, it is good practice to allocate the carbon in HWP to these
activities. Within Article 3 paragraph 3, HWP from Deforestation (D) is treated differently from HWP derived
from A and R activities.
This section describes a default method on how to implement STEP 2 (see Section 2.8.1) for estimating the HWP
contribution originating from forests that are accounted for under the particular forest activities.

Implementation of STEP 2.1
Firstly, the share of carbon in HWP coming from domestic forests is estimated. For this purpose, the share offeedstock from domestic sources remaining within the country as against the overall availability of feedstock
used for subsequent processing within the country (i.e. apparent consumption generally computed fromproduction data plus import minus export) is calculated. In the case of HWP categories sawnwood and woodbased panels, the apparent consumption of industrial roundwood (see Section 2.8.1.1) is assumed to equal thefeedstock used to manufacture those products (Rüter 2011, Johannsen et al., 2011). Some industrial roundwood
can also be used for the production of pulp, serving as feedstock for the semi-finished HWP commodity paper
and paperboard. As pulp is also a traded commodity, the share of pulp produced from domestic sources asagainst the overall availability of pulp is to be calculated in a second step. Generally, domestic consumption iscomputed from production data plus imports less exports.
However, commodities other than industrial roundwood and/or wood pulp can also serve as feedstock for the
production of HWP and the fraction of domestic feedstock in reality differs within the different productcategories (Rüter and Diederichs 2012). For example, substantial amounts of industrial wood residues including
wood chips are used for the manufacture of particle board (Wilson 2010) (cf. Figure 2.8.3). If detailed andrepresentative information on the composition of feedstock and the associated wood flows is available for thesedomestically produced HWP commodities, countries are encouraged to use this country-specific information toestimate the fraction of feedstock from domestic harvest for HWP production and apply Tier 3 (see Section
2.8.4.1).

In STEP 2.2, the carbon in HWP is allocated to the particular forest activities under Article 3, paragraphs 3 and 4(see Figure 2.8.1) as the HWP contribution is estimated differently depending on the origin of the wood. Under
Article 3 paragraph 3, the HWP contribution originating from forest activities A, R and D is estimated since the120

Since the application of the equations only apply to the feedstock calculation, it does not result in the exclusion ofexported HWP (see Sections 2.8.3 and 2.8.4)

It is good practice to apply Tier 2 or Tier 3 methods for the particular fractions of HWP that are derived fromdomestic forests accounted for under FM and AR activities (HWPFM and HWPAR) in line with the provisions set
out in Decision 2/CMP.7 122 (see Section 2.8.1.2 and Figure 2.8.4). In both cases, guidance on estimation
methods is provided in Sections 2.8.3 and 2.8.4. For HWP originating from D activities the Tier 1 method shallbe applied (Section 2.8.2).

If country-specific approaches are not available to allocate domestic harvest and subsequently produced HWP

2.8.3 for estimating the annual fraction of HWP derived from the specific forest activity ( ( )) as a default. This
also includes harvest that has been subject to salvage logging. The identified share of the total harvest is thenassigned to the HWP associated with the particular forest activity by application of Equation 2.8.4.

Where countries already collect data of harvesting discriminating among different activities (i.e. lands subject toFM, lands subject to AR, lands subject to D, and any other treed land) – and among material and energy use of
harvested roundwood (i.e. industrial roundwood and fuelwood, cf. Figure 2.8.2), this information can be used.
This is usually the case where countries apply the gain-loss (i.e. flux data) method123.
Most countries only report industrial roundwood from forests in their statistics and the uncertainties associatedwith feedstock for HWP production (cf. Figure 2.8.2) originating from lands other than forests (see Figure 2.8.4)
are generally expected to be insignificant. However, due to the definition of roundwood (see Section 2.8.1.1), it
may be the case that the specified HWP categories are produced from industrial roundwood (or domestic
feedstock), which does not originate from forests which are accounted for under Article 3, paragraphs 3 (AR and

not considered to be forests (see Section 1.2) and which could provide industrial roundwood to the markets (e.g.
short-rotation plantations), could possibly be accounted for under the activity Cropland Management125 (e.g. as
perennial crops including trees, see Section 2.9). Following the guidance given in Sections 2.9.1 and 2.9.2
countries are encouraged to provide information on how lands that could potentially be the source of industrial
roundwood have been included in their accounting. This is relevant also for forest lands which are not subject toFM, depending on the countries’ interpretation of FM (see Section 2.7.1). It is thus good practice to ensure thatno significant amounts of biomass not originating from forests-related activities have been used as feedstock forthe production of the HWP default commodities, and explain how this has been achieved.
Countries that apply the stock-difference method to estimate forest carbon stock changes as outlined in Section
2.3.3 may need to collect additional data for estimating harvest fractions associated with the particular activity jrelated to forests under Article 3, paragraphs 3 and 4 to apply Equation 2.8.3. When countries cannot track the
harvested wood by the land of origin (FM, AR, D, or from treed lands, cf. Figure 2.8.4) and by different uses ofwood (i.e. industrial roundwood, fuelwood), the following good practice applies:
For deforested lands, the starting information is the standing volume of tree before the deforestation event, whichcorresponds to the total harvest (i.e. fellings). The following steps apply:
STEP 1: Disaggregate the harvest into roundwood and slash by one of the following methods.


Either multiply the standing volume by the ratio of roundwood to total harvested removals that has been
calculated for other activities or at national level;Or divide the standing volume by the biomass expansion factors (BEF2) provided in Table 3A.1.10, Annex
3A.1 to Chapter 3 of the GPG-LULUCF, thereby deriving the amount of roundwood.

STEP 2: Disaggregate the roundwood into industrial roundwood and fuelwood (cf. Figure 2.8.2) by one of thefollowing methods.


Either multiply the roundwood by the ratio of industrial roundwood to roundwood that has been calculated
for other activities or at national level;Or multiply the roundwood data derived from STEP 1 by the factor 0.87126 in order to exclude harvest losses,
bark (cf. FAO roundwood definition, Section 2.8.1.1) and fuelwood not covered by the statistics andsubsequently disaggregate the result by using the proportion derived from FAOSTAT production data of thecommodities industrial roundwood and wood fuel.

For AR lands, the starting information is the standing volume of trees from which fellings is derived accordingwith the age-class structure and/or yield tables and/or information on the timing of harvesting and thinning
operations for each management system. Then, STEPS 1 and 2 as described above for deforested lands apply inorder to divide harvest into roundwood and slash and disaggregate roundwood into industrial roundwood andfuelwood.
For lands that are not reported under any forest-related activity (see Sections 1.1 and 1.2), and that produce
significant amounts of harvest (i.e. lands from which timber is extracted, cf. Figure 2.8.4), then the country
should estimate the amount of industrial roundwood annually produced from those lands in order to exclude it
from the HWP estimation.
Industrial roundwood from those lands could be estimated by:

Either by determining, for each tree species, the total amount of harvest, from which the amount of harvest
originating from AR and D lands is subtracted and the remaining amount is apportioned among lands subject
to FM and other lands from which significant amounts of timber are extracted based on the proportion of thetotal area covered by each species under FM and under those other lands; or

Or by subtracting from the total harvest the amount of fellings originating from AR and D lands, as
quantified by available data or as estimated according to above-listed guidance, and, then, apportioning theremaining quantity on the basis of the proportion of the area under FM and under those other lands.

2.117

Chapter 2: Methods for estimation, measurement, monitoring and reporting

Once the amount of fellings has been apportioned to lands not reported under any forest-related activity fromwhich significant amounts of timber are extracted the industrial roundwood is estimated by applying the same
steps as those described for afforested/reforested lands.
Finally, the amount of industrial roundwood produced from FM lands is estimated by subtracting from the total
harvest the quantity of fellings originating from AR, D and those other lands and by calculating the amount ofindustrial roundwood associated with FM in line with the guidance given above.
For each forest-related activity, for the years of the time series for which a ratio of industrial roundwood
originated by the activity to the total produced roundwood cannot be estimated, it is good practice to derive
missing values from the values of the ratio that have been calculated according to methods of gap-filling as
provided in the 2006 IPCC Guidelines.
Countries that use the stock-difference method to estimate forest carbon stock changes as outlined in Section
2.3.3, and that apply the above-listed good practice for estimating the fellings for D, AR and/or FM, areencouraged to ensure the quality of estimated values of harvesting by checking their consistency with theestimated net changes in aboveground biomass.
In case it is not possible to differentiate between the harvest from AR and FM, it is conservative and in line withgood practice to assume that all HWP entering the accounting framework originate from FM. The reason is thatthe potential contribution to the reported carbon stock changes is higher if HWP originate from AR rather thanfrom FM, as for AR, the estimates start in 1990 and AR is accounted against a benchmark value of 0 (i.e. grossnet accounting, see Sections 2.5.3 and 2.8.3). It is furthermore conservative and in line with good practice toassume that all harvested wood prior to the start of the first commitment period is derived from FM, since theannual fraction of feedstock for HWP originating from forest activities under Article 3, paragraphs 3 and 4( ( )) can only be estimated from information available from the first and second commitment periods.

Implementation of STEP 2.3
In order to obtain the annual fractions of HWP entering the accounting framework from domestic harvest( ) andassociated with the particular activity j (AR, D and FM), the results of STEP 2.1 (i.e. the factors (( )) from Equations 2.8.1 and 2.8.2) and STEP 2.2 (i.e. ( ) from Equation 2.8.3) are, as a default, to be
combined with the annual production of the HWP commodity categories (HWPP) as specified in Section 2.8.1.1(i.e. sawnwood, wood-based panels, paper and paperboard). In cases where no country-specific track and tracesystems are available, it is good practice to apply Equation 2.8.4 for this purpose.

Chapter 2: Methods for estimation, measurement, monitoring and reporting

2.8.2

Tier 1: “Instantaneous oxidation”

The method presented in this section is to be applied by countries as the default method to estimate the HWPContribution.127 It is based on the assumption that the annual amount of carbon leaving the HWP pool is thesame as the annual carbon inflow to the pool. In consequence, this method corresponds to an estimate of nochange in HWP carbon stocks. It equals the assumption that all carbon in the biomass harvested is oxidised in
the removal year (i.e. year of harvest) and is equivalent to reporting no net-emissions from HWP, as the annualchange in carbon stock in HWP is zero (cf. IPCC 1997, IPCC 2006).
For the first commitment period, the storage of carbon in HWP was not included in the reporting since “the mere
presence of carbon stocks be excluded from accounting” 128 and HWP “is not listed as a pool covered by the
Marrakesh Accords” (IPCC 2003). Countries following the good practice as described in GPG-LULUCF (IPCC
2003) and applying instantaneous oxidation, did thus not report and/or account for emissions from HWP in thefirst commitment period.
Decision 2/CMP.7 establishes mandatory accounting of all changes in the HWP pool. 129 A prerequisite foraccounting HWP on the basis of delayed emissions is the availability of transparent and verifiable HWP activity
data (see Section 2.8.1.1). Consequently, it is good practice to apply the Tier 1 method as outlined in this section(i.e. reporting no net-emissions from HWP) only in the case that transparent and verifiable activity data for thedefault HWP categories sawnwood, wood-based panels and paper and paperboard as outlined in Section 2.8.1.1
are not available.130 However, Decision 2/CMP.7 specifies that “the treatment of HWP in the construction of a
projected FMRL (see Section 2.8.5) shall not be on the basis of instantaneous oxidation”.131
For the following HWP fractions instantaneous oxidation (i.e. Tier 1) shall be applied (see Figure 2.8.1):


HWP resulting from D activities under Article 3 paragraph 3 (see Section 2.8.1.2);132



HWP in SWDS 133

Harvested wood used for energy purposes.133

Following the guidance given in Section 2.8.1.2, the fraction of HWP originating from domestic forests that are
accounted for under the activities AR and FM can be derived. Thereby, the fraction of HWP resulting from D is
implicitly excluded from further estimation of the HWP contribution and which is equivalent to applying
instantaneous oxidation. In line with the requirements of Decision 2/CMP.8134, it is good practice to demonstratethat harvested wood originating from D (i.e. harvestD, see Equation 2.8.3) has not been included in the estimateson the basis of the change of the HWP pool. This can be done by reporting the annual share of the overall harvest
originating from D (harvestD (i)).
By estimating the HWP contribution on the basis of methodologies as outlined in Sections 2.8.3 and 2.8.4, only
the HWP contribution of HWP in use is estimated. HWP in SWDS and wood harvested for energy are thus
implicitly treated on the basis of instantaneous oxidation (i.e. reporting no net-emissions from HWP). Estimatesthat are based on the three default commodities are by definition not derived from wood harvested for energy
purposes. Where CO2 emissions from HWP in SWDS are separately accounted for, it is good practice to include
them on the basis of “instantaneous oxidation”.

required to obtain estimates on the HWP contribution by application of the Tier 2 method as outlined in thissection.135
In line with Decision 2/CMP.7, it is good practice to estimate the change in carbon stocks separately for each of
the HWP fractions originating from AR (HWPAR) and from FM (HWPFM) as estimated from Equation 2.8.4. For
this purpose, the first-order decay (FOD) function as presented in Equation 2.8.5, which is a flux data methodthat corresponds to Equation 12.1, Chapter 12, Volume 4 of the 2006 IPCC Guidelines, is to be applied:

Where:
i = yearC (i) = the carbon stock in the particular HWP category at the beginning of year i, Gg C
k = decay constant of FOD for each HWP category (HWPj) given in units yr-1 (k = ln(2)/HL, where HL ishalf-life of the HWP pool in years (see Section 2.8.3.2).
Inflow (i) = the inflow to the particular HWP category (HWPj) during year i, Gg C yr-1
ΔC(i) = carbon stock change of the HWP category during year i, Gg C yr-1
It is good practice to apply Equation 2.8.5 with activity data for the semi-finished wood product categories
sawnwood, wood-based panels and paper and paperboard that have been assigned to the particular forest
activities (HWPAR and HWPFM) (see Section 2.8.1). In combination with semi-finished wood productcommodities, FOD implicitly includes finished HWP in the pool estimates, and it is assumed that “immediate
losses of the HWP pool due to final processing along the processing chain (cf. Figure 2.8.2) are described
realistically by the exponential decay pattern” (Pingoud and Wagner 2006). The timing of emissions from woodprocessing residues used for energy purposes along the process chain of HWP are also well described by FOD(cf. Rüter and Diederichs 2012).
Whereas Equation 12.1, Chapter 12, Volume 4 of the 2006 IPCC Guidelines suggests to start with i = 1900,
application of FOD in the context of the Decision 2/CMP.7 necessitates a differentiated approach to enable HWP
accounting associated with the different forest activities (see Section 2.8.1.2).
In order to produce an estimate of the existing HWP carbon pool by means of Equation 2.8.5, and based on thesubsequent changes of this pool to produce an estimate of the HWP contribution, the historical wood use (i.e. theaccumulation of the historic Inflow to the HWP pool) has to be included. This procedure is needed as this also
includes the historic and current discard from the HWP pool, which is also termed “inherited emissions” (IPCC
2006). This is reflected in Decision 2/CMP.7, which states that “emissions that occur during the second
commitment period from harvested wood products removed from forests prior to the start of the second
commitment period shall also be accounted for.”136 The term “emissions” from HWP (which are defined as apool137) thus refers to the “decay” from that pool, which is the discarding of HWP from end uses described e.g.
by FOD (i.e. Equation 2.8.5). Discarding, thus, does not mean that the carbon in the products is oxidized, but
describes the release of HWP from the HWP pool in use (or in service) from where the products are potentiallyrecycled, burned, composted or transferred to solid waste disposal.138 The discard from the pool of HWP in use(comprising wood products in service), therefore depends on the historic level of Inflow (see Section 2.8.1) andthe particular service life and/or half-life of the HWP commodities (see Sections 2.8.3.2 and 2.8.4.2).

2013 Revised Supplementary Methods and Good Practice Guidance Arising from the Kyoto Protocol

Chapter 2: Methods for estimation, measurement, monitoring and reporting

In order to account for the HWP contribution from AR activities, estimates are to be based on activity data since
the base year 1990. It is thus good practice to include inherited emissions from the pool that has been establishedfrom HWPAR since 1990. This is implemented by the use of Equation 2.8.5 starting with i = 1990 andC(1990) = 0.
For HWP from FM activities, the inclusion of inherited emissions in the estimates of the HWP carbon pooldepends on the Party’s approach used for FMRL construction. In case the FMRL is based on a projection which
represents a ‘business as usual scenario’ (see Sections 2.7.5.1 and 2.8.5), Parties may exclude inherited
emissions from before the start of the second commitment period in their estimates. 139 In this case, the estimation
by means of Equation 2.8.5 starts with i = 2013 and C(2013) = 0. If the Party’s FMRL is not based on a
projection representing a ‘business as usual scenario’, it is thus good practice to include inherited emissions fromthe pool.
( )), it is also good practice to separately estimate and report using the

HWP from AR activities (HWPAR) and for HWP from FM activities (HWPFM)

HWP for each of the particular commodities (i.e. sawnwood, wood-based panels, paper and paperboard ortheir subcategories)

The availability of activity data series (i.e.
( )) varies. For most countries the FAO statistics provide dataon the HWP commodity categories since 1961.140 However, for some countries activity data are available only
since their independence or foundation (e.g. in 1991). Further guidance on the activity data to be used for the
Tier 2 method is provided in Section 2.8.3.1.
As a proxy in the Tier 2 method it is assumed that the HWP pools are in steady state at the initial time t0 fromwhich the activity data start. This means that as a proxy ΔC(t0) is assumed to be equal to 0. This steady statecarbon stock C(t0) for each HWP commodity category is approximated by means of Equation 2.8.6 based on the
average of Inflow(i) during the first 5 years for which statistical data are available. By substituting C(t0) in
Equation 2.8.5, the C(i) and ΔC(i) in the sequential time instants can be calculated. In the Tier 2 method, it isgood practice to use Equation 2.8.6 for estimating the stock at t = t0.

Only in case a projected FMRL is applied (see Section 2.8.5), other methods could also be used. Further
estimation methods for calculating the carbon inflow to the HWPFM pool (Inflow(i)) back to the year 1900 areprovided by the 2006 IPCC Guidelines (i.e. on the basis of estimated annual rates of increase for industrial
roundwood production that are based, inter alia, on the annual per cent change of population growth) or in Rüter
2011 (i.e. calculate missing activity data since the year 1900 on HWPFM carbon pool inflow from the average ofthe first five years for which activity data are given for the country).
In case the FMRL has been based on a projection representing a ‘business as usual scenario’ (see Section 2.7.5
and 2.8.5), in line with Decision 2/CMP.8, it is good practice to provide information whether and how inherited
emissions have been included in the HWP estimates. Otherwise, if the inclusion of HWP in the countries’ FMRL
is not based on a projection, it is good practice to explain that the approach chosen to include inherited emissions
in the estimates of the HWP carbon pool reflects best the countries’ circumstances (e.g. data availability).
Further guidance on the consideration of HWP in the FMRL is provided in Section 2.8.5.

The carbon stock change in all the HWP pools of the commodities associated with the particular activities isobtained by summing the stock changes ΔC of each commodity category. The carbon stock change is thenconverted into Gg CO2 yr-1 by multiplying by –44/12.
Under the Tier 2 method, Equation 2.8.5 is equally applied for domestically consumed as well as for exported
HWP together with the same half-life parameters (see Section 2.8.3.2). Therefore, it complies with good practice
not to differentiate between domestic consumption and exports in the reporting of the HWP contribution. In
order to increase transparency and facilitate potential changes in the methodology used to estimate the HWP
contribution (e.g. by application of country-specific half-lives following the guidance provided in Section 2.8.4),
however, Parties are encouraged to report separately for domestically consumed and exported HWP.

2.8.3.1

A CTIVITY DATA

Activity data include the carbon stock of the HWP pool at the beginning of each year ( C(i)) and the inflow to the
HWP pool during each year (Inflow (i)) for each HWP category. In order to apply Equation 2.8.5, it is goodpractice to determine C(i) and Inflow (i).

2013 Revised Supplementary Methods and Good Practice Guidance Arising from the Kyoto Protocol

Chapter 2: Methods for estimation, measurement, monitoring and reporting

For this purpose, Tier 2 uses forest products data from the FAO or other international organizations, such as theUnited Nations Economic Commission for Europe (UNECE), for semi-finished HWP commodities as set out in
Section 2.8.1.1. As a default, the annual Inflow(i) to the HWP pool comprises of the three default HWP
commodity categories, i.e. sawnwood, wood-based panels, paper and paperboard), separated by the particular( ), see Section 2.8.1.2).
activity (In order to estimate carbon amounts in HWP, default conversion factors are provided in Table 2.8.1. In fact, theconversion factors for the HWP default commodities (i.e. aggregates) are largely dependent on the compositionof countries’ production amounts of the particular subcategories (e.g. particle board). If Parties havedisaggregated data on subcategories of semi-finished wood products as listed in Table 2.8.1, it is thus goodpractice to apply Equation 2.8.5 to the disaggregated subcategories.
In order to reduce uncertainties associated with assumptions on the conversion factors of activity data (i.e. dataon semi-finished wood product commodities derived from statistics) (see Section 2.8.6), Parties are encouraged
to use country-specific activity data comprising further items of the HWP subcategories as listed in Table 2.8.1.
More information can be obtained in Section 2.8.4.1.

2.8.3.2

E MISSION FACTORSThe rate at which carbon in the default HWP categories is removed from the HWP pool in service in a given year
is specified by a constant decay rate (k) expressed as half-life in years. The 2006 IPCC Guidelines define thehalf-life as “the number of years it takes to lose one-half of the material currently in the pool”. As the half-life in
the context of Decision 2/CMP.7 refers to HWP in use (see Section 2.8.1.1), the half-life to be applied is afunction of the adjusted estimated service life (ESL) of the particular HWP commodities (with HL = Adjusted
ESL * ln(2), see Section 2.8.4.2).
When applying the Tier 2 method, Decision 2/CMP.7 requires countries to use the default half-lives of the three
HWP categories as specified in Table 2.8.2. The same half-lives apply for the particular subcategories of theaggregate HWP categories as specified in Table 2.8.1.

In order to reduce uncertainties associated with the assumptions on the half-lives of the HWP commodities (seeSection 2.8.6) Parties are encouraged to use country-specific half-lives, both for the domestic use of HWP
categories, as well as country-specific half-lives as being applied by the importing country for the exported HWP
categories. Further guidance on how to use and obtain country-specific half-life information (i.e. Tier 3) for the
relevant HWP categories is available in Section 2.8.4.2.

2.8.4

Tier 3: Country-specific methods

This section provides good practice guidance on the use of country-specific methods to estimate the HWP
carbon pool and its changes in order to estimate the HWP contribution. They may include country-specific halflives and/or methodologies and may be applied by Parties where sufficient data are available, in line withrequirements as outlined in Section 2.8.1 and the Decision 2/CMP.7143 covering the three semi-finished HWP
categories. It complies with good practice to apply country-specific methods “provided that verifiable andtransparent activity data are available and that the methodologies used are at least as detailed or accurate”143 as
those described in Section 2.8.3 (Tier 2). Good practice thus includes a verification of the Tier 3 methods used,141

See footnote of paragraph 29 of Decision 2/CMP.7: Half-lives are based on Table 3a.1.3 of the GPG-LULUCF.

e.g. by comparing the results derived using the Tier 2 method (see Section 2.8.3), and by providing all relevant
information in a transparent and verifiable way to demonstrate how the HWP contribution has been estimated.
More information on how to verify Tier 3 methods can be found in IPCC FAQs on HWP.144
Two key Tier 3 methodological pathways allow for estimating changes in the HWP carbon pool in line with therequirements as outlined in Decision 2/CMP.7, comprising (i) flux data methods, and (ii) combinations of stock
inventory and flux data methods.

FLUX DATA METHODSIn flux data methods HWP carbon pool and its changes are basically calculated from the difference of the
production (i.e. carbon inflow to the HWP pool) and decay/discard rate. There are comprehensive international
activity databases on the production and trade of HWP (see Section 2.8.1.1), whereas information on the discard
from the HWP pool is incomplete. Using this incomplete discard information (e.g. from waste statistics) to
calculate the above difference would lead to an overestimation of the HWP carbon pool and its changes. Thus
practicable flux data methods that comply with good practice rely on service life information of HWP. They arebased on the use of decay functions and dynamic models ensuring the continuity of mass so that all HWP carbon
entering the pool will be discarded eventually.
The following alternatives under a Tier 3 method could be used:

The Tier 2 FOD function (see Equation 2.8.5) is a special case of flux data methods and could also be
applied under Tier 3 with:(i)

Default half-lives in combination with country-specific activity data for disaggregated commodity
items (e.g. HS code 440792 sawnwood made of beech (Fagus spp.) of a certain dimension)
included in the three HWP commodities that follow the HS nomenclature system as explained in
Section 2.8.1.1 (see Section 2.8.4.1)(ii)

Country-specific half-lives to be based on national information on service life of the default HWP
commodities or their sub-categories (see below and Section 2.8.4.2).

Other country- or product-specific decay functions could be applied. Examples of different decay functions
include logarithmic decay (e.g. Karjalainen et al., 1994), retention curves (e.g. Skog and Nicholson 1998)
and distribution functions (e.g. Marland et al., 2010). They could be used in combination with:(i)

Default half-lives (see Table 2.8.2), or country specific half-lives as specified in Section 2.8.4.2(ii)

Country-specific activity data (see Section 2.8.4.1).

Furthermore, it is with good practice to separately estimate and report the HWP contribution of the HWP poolfor the domestic market (i.e. reporting Party) and for export markets, in case:Country-specific half-lives or decay functions, and/orCountry-specific activity data (i.e. other than specified in Section 2.8.3.1) are used.

In the case HWP pools of both semi-finished and finished products are included in Tier 3 calculation models it isgood practice to eliminate any overlapping of the HWP pools and thereby to avoid any double-counting of HWP
carbon stock changes.

COMBINED HWP STOCK I NVENTORY AND FLUX DA TA METHODSHWP stock inventory methods use HWP carbon pool data for two or preferably more separate points in time toestimate changes in the pool. Their application is basically relevant for HWP pools in the reporting country alone(see Section 2.8.4.1) and could be used to estimate the annual change in carbon stock of some specific finishedHWP pools (cf. Figure 2.8.3) such as buildings. Examples of such inventories are reported in Gjesdal et al.,(1996) for Norway, in Pingoud et al., (2001) and Statistics Finland (2011) for Finland.
In the case of inventory methods, no procedure for adding up wood use data from historical data is needed toestimate the existing HWP stock or annual change in stock, which is an advantage compared to the flux methods(IPCC 2006). However, a fundamental problem in the application of inventory methods alone for the present
accounting purpose is the identification of the proportion of the HWP carbon stock originated from domestic
forests and being thus accountable (see Section 2.8.1). Furthermore, in line with Decision 2/CMP.7, imported
HWP must be excluded from the estimated HWP pool, therefore increasing the uncertainties.145

Since in practice inventory data are not available for all finished HWP for domestic and export markets covering
the HWP categories sawnwood, wood-based panels, paper and paperboard (e.g. wooden houses, furniture,
newspaper), it is good practice to apply inventory methods only in combination with flux data methods.
In cases where a Party applies inventory methods for specific HWP end uses (e.g. the housing sector), it is thus
good practice to estimate the HWP contribution for the remaining fraction of the three HWP default
commodities in combination with the flux-data method under Tier 2 or 3. For this purpose, the three HWP
categories being used in the housing sector must be factored out from the flux-data calculation to avoid doublecounting and to meet the requirements of Decision 2/CMP.7.

2.8.4.1

C OUNTRY - SPECIFIC ACTIVITY DA TA

Section 2.8.1.1 introduces the international classification system of forest products following HS nomenclature,
which is also relevant for activity data used for a Tier 3 method. Whereas data for semi-finished HWP can beobtained from national statistics as well as from international databases, HWP activity data other than outlined in
Section 2.8.3.1 (see Table 2.8.1) are available from national sources only. In the case of Parties using countryspecific activity data as described in this section, it is good practice to disclose the source of data and provide in
a transparent and verifiable manner additional information for items that make up subcategories and/or final
products produced from the three default HWP categories as defined in Decision 2/CMP.7146 (cf. Figure 2.8.2).
Country-specific HWP activity data that could be used for Tier 3 include:
1.

Item data following the international HS nomenclature and classification system

These data could be available from country-specific statistics containing further disaggregated items of thesubcategories as specified in Table 2.8.2. Examples would be coated particle board, fibreboard with specificdensity or surface, or coniferous sawnwood made from specific tree species (e.g. larch). Introducing
disaggregated item data using appropriate carbon conversion factors e.g. based on information on wood densities
can contribute to considerably improve the accuracy of the HWP estimations. Further information could beobtained e.g. from Forest Products Laboratory (2010).
In some cases, the aggregated datasets for the specified HWP categories available from national statistics aredifferent from available databases of international organizations (e.g. FAO or UNECE). In order to reduce
uncertainties associated with the use of these datasets (see Section 2.8.6) and in order to provide country-specificactivity data in a transparent and verifiable way, Parties are encouraged to explain the differences between data
used from national sources from data provided in international databases.
2.

Finished HWP not containing components with different service lives

These types of activity data refer to finished HWP that do not contain components with different potential halflives. They are made up from at least one of the (default) semi-finished HWP categories (see Figures 2.8.2 and2.8.3). This group of products comprise e.g. doors, flooring systems, books or furniture, which could also be
obtained from national production statistics (e.g. furniture production statistics).
3.

Data on buildings with different wooden construction components with different renovation intervals

These types of products rather represent a market segment where finished products (see above) are used (seeFigure 2.8.3). Wooden houses are composed of different construction components with different renovationintervals, e.g. long lived roof construction made of beams, wall systems, and comparatively short-lived wooden
flooring systems. Country-specific activity data for buildings could again be derived from the production
statistics (e.g. Building Construction Starts Statistics) or from inventories and surveys.
Some of the above mentioned country-specific activity data (1, 2 and 3) may be available from annual statistics
being applicable for flux data methods. Other activity data might be available only at the start and at the end of
the commitment period for use in combined HWP stock inventory and flux data methods. Whereas data derived
from inventories (e.g. for buildings, see 3) could not be used for the share of exported HWP, data fromproduction and export statistics for finished product categories, such as books or furniture, could be used toestimate the contribution of exported HWP.
In order to allocate the carbon in HWP to the particular forest activities under Article 3, paragraphs 3 and 4 (seeSection 2.8.1.2) Parties could apply the relevant equations as suggested in Section 2.8.1 for use in Tier 3
methods. Nevertheless, Parties are encouraged to estimate carbon in HWP originating from domestic forests
using more country-specific information, including e.g. detailed data on the use of timber assortments for thesubsequent processing of HWP categories (e.g. wood pulp, recovered wood pulp from recovered paper, etc. for
146

Paragraph 302013 Revised Supplementary Methods and Good Practice Guidance Arising from the Kyoto Protocol

2.125Chapter 2: Methods for estimation, measurement, monitoring and reporting

paper and paperboard). Provided country-specific approaches are available for this purpose, it is good practice todemonstrate and report how the allocation has been done to meet the requirements as set out in Decision
2/CMP.7.
When using country-specific activity data, information on carbon conversion factors (see Table 2.8.1) may not
be readily available. In particular, HWP activity data representing finished commodities (see Figure 2.8.2) ormarket segments of wood use (e.g. wooden building components, see Figure 2.8.3 in Section 2.8.1.2 and Table
2.8.3 in Section 2.8.4.2) often include mixes of wood and other materials. In this case, specific conversion
factors could be obtained from statistics or from life cycle inventory (LCI) information, which forms the basis
for life cycle assessment (LCA) according to ISO 14040:2006 (ISO 2006a) and 14044:2006 (ISO 2006b).
Information on the average amount of wood content per unit could be provided e.g. per square meter of floor
space (Tsunetsugu and Tonosaki 2010). Examples of representative LCI information are reported e.g. in Rüter
and Diederichs (2012) for Germany.
When using such specific conversion factors, it is good practice to demonstrate and report how conversion
factors have been derived and provide information on the representativeness of associated data with regard totime, technology and geographical scale (see e.g. European Union 2010).

2.8.4.2

C OUNTRY - SPECIFIC EMISSI ON FACTORSThis section gives guidance on the concept of service life and half-life information to estimate the HWP
contribution on the basis of flux data methods.
In general, national values for service- or half-life could be derived for the three default HWP categories andtheir subcategories (see Section 2.8.1.1). But also other HWP categories could be established and combined withthe respective service life information. However, in order to ensure that the methodology used is at least as
accurate as the one described in Section 2.8.3, Parties are encouraged to make those HWP categories broad
enough to capture significant carbon volumes contributing to the HWP pool. As a guide, the volumes of HWP
categories are deemed significant if they represent at least 5% of the total HWP production.
Potential data providers and sources for national service life information are national and industry agencies,
technical literature and direct consultations (i.e. surveys of experts, industry and the general public). It is
important to note that service- and half-life values representing the material use of wood can differ notably
among and within countries depending on factors such as construction practices, culture, fashion, and climate.
Thus, in case country-specific information is used, a national quality control system is encouraged in order toprovide transparent and verifiable data.
Several approaches can be used to derive country-specific service- and half-life values based on transparent andverifiable data:Following the ISO 15686 standard series approach, since this is an already established system for service life
estimation on a case specific level. A modified approach is used here on a national level (see Box 2.8.1) in
combination with obsolescence on national level,A combination of production and trade statistics data with building stock inventory information in order toestimate more realistic country-specific service and half-live values through this calibration, and/or

National surveys on the final market use of wood.

Below examples on how to improve service life estimates based on the ISO 15686 series are shown, and an
example of HWP half-life calculation for HWP categories is given based on its ESL (see Section 2.8.3.2), in
combination with an obsolescence factor and information on its market share.
In order to adequately apply flux data methods based on information on country-specific HWP service life (i.e.
time carbon is held in HWP pool in use before they are disposed or recycled), apart from the concept of half-life(see Section 2.8.3.2), the following terms and concepts are to be differentiated:ISO 15686-1:2011 defines the reference service life (RSL) as the service life of a product, component,
assembly or system which is known to be expected under a particular set, i.e. a reference set of in-use
conditions;.



The ESL on the other hand is the service life that a wooden or wood based component would be expected tohave in a set of specific in-use conditions. It is determined from RSL data after taking into account any

Chapter 2: Methods for estimation, measurement, monitoring and reportingObsolescence arises (according to ISO 15686-1:2011) when a facility no longer can be adapted to satisfychanging requirements. Obsolescence tends to result from unexpected changes, often unrelated to theconstruction, and includes:(i)Functional obsolescence: the function is no longer required.

(ii)

Technological obsolescence: new alternatives can offer better performance, change the pattern of
use.

(iii)

Economic obsolescence: Fully functional but less efficient, more expensive than alternatives. This
also includes replacement due to changing fashion or taste.

ISO 2011 states that estimates of obsolescence should be based on the designer’s and clients experience, and, if
possible, documented feedback from practice. In order to estimate the carbon storage of HWP in use and its
impact on emissions/removals by means of flux data methods using country-specific service life information, itis thus good practice to take into account obsolescence and to distinguish replacement of HWP in use due to e.g.
a defective performance from obsolescence (cf. ISO 2011).
For example:
In northern Europe a wooden decking can last for 50 years or more given proper construction and choice ofmaterial. But the same decking is likely to be replaced already after 20 years (or less) e.g. due to aestheticalreasons. Hence, for calculating country-specific ESL or half-life values an obsolescence factor is needed in Tier
3 estimates of the HWP contribution to reflect the time actually spent in the HWP carbon pool, not the potential
full service life of a wooden component given by ESL.
In this guidance document the ESL is applied for estimates on a national level and not for a specific case as
suggested in the ISO 15686 standard series. To include the effect of obsolescence:

Either an additional factor (O) is included, with(i)

Obsolescence = 1 when there is considered to be no significant effect of obsolescence compared to
RSL

(ii)

Obsolescence is given a value < 1 based on the intensity of obsolescence(iii)

Obsolescence can never be larger than 1.

Or a decay function to be assigned that uses the service life data to estimate the decay profile (based on
products leaving the pool, not only biological decay and not a biological decay profile) or the actual time
path that products take to go out-of-use.147

An example of how to derive national service life estimates by means of the factor method is given in the box
2.8.1 below.

EXAMPLE ON THE CALCULATION OF NATIONAL ESL BY MEANS OF FACTOR METHOD

A theoretical example with wooden claddings in Norway is given based on ISO 15686-8:2008, butelevated from the case specific level given in the standard to a national level. Details about RSL
and service life estimation are in ISO 15686-8:2008.
A factor of “1” is used when the factor does not deviate from the RSL conditions. A higher value(x>1) is given if the national performance is better than RSL conditions; a lower value (x<1) isgiven if the national performance is lower than the RSL conditions. Non relevant factors are
excluded from the equation.
The RSL is based on accelerated field trials and the threshold for failure was defined when themean decay rating reached 2 (on a scale from 0–4 where 0 is no decay and 4 is failure).
National ESL = 55(RSL)*1(A)*1(B)*1(C)*1.2(E)*1(F)*0.9(G) = 59.4 years
Factor D ‘indoor environment’ is excluded because it is not relevant. It is good practice to include
factors that do not deviate from the RSL even if they do not contribute in changing the RSL since
they are given the value 1. A more detailed explanation for the choice of factors used is to beprovided in the countries’ annual reporting.
A = Inherent performance level represents the grade of the component as supplied.
- Here equals the RSL.
B = Design level reflects the component’s installation in the building/constructed asset and istypically based on the level of shelter and protection from agents provided by the design of thebuilding/constructed asset.
- Here equals the RSL.
C = Work execution level considers the level of skill and control in sitework.
- Here equals the RSL.
D = Indoor environment considers the exposure of the object to indoor agents of degradation andtheir severity.
- Not relevant in this example.
E = Outdoor environment considers exposure to outdoor agents of degradation and their severity.
- In this example the climate on a national level is less harsh than at the test sites included in RSL.
F = Usage conditions reflects the effect of the use of the building/constructed asset.
- Here equals the RSL.
G = Maintenance level reflects the level of maintenance assumed. For certain components that are
inaccessible or require special equipment for access, a particularly low maintenance level should
be considered.
- Here slightly lower than RSL intervals.
Another example in Table 2.8.3 shows how to derive country-specific half-life values for the three aggregate
HWP categories (see Section 2.8.1.1) as a function of information on market share of the use of wood (seeabove), ESL and obsolescence. The use of composed HWP categories in different markets, such as in theconstruction sector, can be divided further into different segments (e.g. wall systems, flooring, and roof
construction). These different segments normally have different service lives and obsolescence factors. Hence,
Parties are encouraged to allocate the contribution of the different HWP categories or subcategories (e.g.
coniferous sawnwood) to markets and their segments in order to obtain improved service life estimates for theparticular HWP categories. Thereby, it is important to note that the assumed service life is driven by the products
technical properties and, depending on this, its particular application area (e.g. load-bearing beam or wood
panelling, both made of sawnwood). Thus, in order to calculate a country-specific emission factor (i.e. serviceor half-life), different sources of information, e.g. on the market use of different HWP categories, could be
combined as illustrated in Table 2.8.3.
The definition of half-life and also guidance on how to calculate half-life for Tier 2 is provided in Section
2.8.3.2.

subcategory (e.g. non-coniferous sawnwood used for windows).

HALF-LIFE DATA TO BE USED FOR EXPORTED HWP“In the case of exported HWP, country-specific data refers to country-specific half-lives and HWP usage in theimporting country.”148 Thus, if country specific half-life information should be used also for the exported HWP
categories, the half-life information from the importing country must be used. For this purpose, it is necessary toquantify export activity data within the three HWP categories and/or sub categories. Furthermore, in order toensure that the country-specific half-life information from the importing country complies with the categories of
the activity data for the exported HWP, it is good practice to only apply country-specific half-life information incase the same categories of activity data for the exported HWP both in the exporting and importing country areused. Otherwise the default values (Tier 2) are to be used. When transparent and verifiable activity data are
available, the categories should be broad enough to capture significant volumes contributing to the pool. The
amount of exported and domestic wood should be separately reported.

Consideration of the HWP pool in FMRLs

In this section, guidance is given on the relation of HWP originating from FM as described in Section 2.8.1 andits consideration in the FMRL as outlined in the Decisions 2/CMP.6149, 2/CMP.7 and 2/CMP.8. Guidance on the
FMRL is provided in Section 2.7.5.

APPROACHES AND METHO DS FOR CONSIDERATION OF HWP IN FMRL
Decision 2/CMP.6 requested Parties to inter alia submit descriptions of how HWP were considered in theconstruction of the FMRL.150 In line with the different approaches and methods used by Parties to construct the
FMRL as listed in Section 2.7.5.1, two general approaches on how to treat HWP in FMRL can be differentiated:1.

Instantaneous oxidation

In this case, Parties only presented values for a FMRL which do not contain estimates on the HWP
contribution.151 Similar to the treatment of HWP in the first commitment period as described in GPG-LULUCF,

2.129

Chapter 2: Methods for estimation, measurement, monitoring and reporting

as result of the assumption of instantaneous oxidation, changes in the HWP carbon pool are not reported (cf.
Section 2.8.2). This approach mirrors the HWP Tier 1 estimation method as described in Section 2.8.2.
2.

Inclusion of the HWP pool on the basis of modelled projections under a ‘business as usual’ scenario

In this case, Parties presented values for the FMRL that include estimates of the HWP contribution based onchanges in the HWP pool.152 This approach was chosen by Parties following the FMRL approaches 1a) and 1b)
as described in Box 2.7.3. Many countries derived the values for the projected HWP contribution by means of
FOD as specified in Section 2.8.3 for the Tier 2 HWP estimation method (Equation 2.8.5) applying default halflives as listed in Table 2.8.2 for the HWP categories sawnwood, wood panels and paper (see Section 2.8.1.1).153
However, different approaches had been used in regard to the consideration of HWP originating from forests
prior to the start of the second commitment period154, as indicated in the application of HWP activity data (i)since 1900, or (ii) since 1990.
BOX 2.8.2
EXAMPLE ON THE ESTIMATION OF THE HWP CONTRIBUTION AS PRESENTED IN PARTIES’ FMRL

The following example is intended to show, how estimates of the projected HWP contribution
based on changes in the HWP pool could be derived that are consistent with the assumed
harvesting rates following a ‘business as usual’ scenario in case no country-specific information on
assumed future production of HWP and/or ‘track and trace’ models were available (cf. Rüter
2011).
In line with the guidelines for the submission and review of information on FMRL contained in the
Appendix II of Decision 2/CMP.6, Parties had been requested to provide information on historicand assumed harvesting rates following a ‘business as usual’ scenario for FM.
STEP 1: Calculation of the rates of change of the projected harvest as compared to the last five
years’ average of the historic harvest, for which up-to-date data were available.
Numeric example:
(i)
(ii)
(iii)

Average historic harvest for the years 2005-2009: 50 Mm³ yr-1
Projected harvest (in Mm³ yr-1): in 2013=52, in 2014=53, in 2015=55 …
Rates of change as compared to historic average: in 2013=4%, in 2014=6%, in 2015=10%

STEP 2: Application of these annual change rates to the same five year average of historic carbon
inflow to the HWP pool, which has been calculated from HWP production (see Section 2.8.3), in
order to project the future carbon inflow to the HWP pool.
Numeric example:
(i)
(ii)

Average production of sawnwood for the years 2005-2009: 10 Mm³ yr-1
Projected production of sawnwood (in Mm³ yr-1): in 2013=10.4, in 2014=10.6, in 2015=11 …

As a result, it is assumed that the same average proportion of harvested timber used as feedstock
for the subsequent production of HWP in the chosen historic five year period will also apply in the
projection period.
A five year average was chosen, in order to reduce the uncertainties associated with theconsiderable variability in the proportions of harvested timber being used for HWP production
from year to year. A similar approach had been proposed by Kangas and Baudin (2003). In case of
substantially varying time series, they suggest to use a ‘fixed constant’ as the projection that is anaverage over the last five years.

Besides these two basically different methodological approaches in the treatment of HWP in the FMRL, further
distinction between Parties’ estimates on the HWP contribution to the FMRL can be recognized for (i) theapplied models that have been used (including activity data, carbon conversion factors, etc.), and (ii) the applied
underlying assumptions regarding the projected HWP contribution and/or its relation to particular projected151

METHODOLOGICAL CONSI STENCY BETWEEN HWP I N THE FMRL AND
THE REPORTING DURING THE SECOND COMMITMEN T PERIOD
General guidance on methodological consistency in relation to the FMRL is provided in Section 2.7.5.2.
In line with Decision 2/CMP.7, it is good practice to demonstrate methodological consistency between thetreatment of HWP in the FMRL and the reporting for FM during the second commitment period.155 Since thefinal agreement on HWP, included in the Decision 2/CMP.7, was reached after the FMRL submissions, atechnical correction for accounting purposes as described in Section 2.7.6 might be needed in the estimation of
the HWP contribution to the FMRL to reflect the changes in the applied methodological elements as described
below and in the relevant Sections 2.8.1, 2.8.2, 2.8.3 and 2.8.4. In order to check methodological consistency it isgood practice to follow the decision tree provided in Figure 2.8.5.

2.8.6

Uncertainty assessment

This section provides information on potential sources of uncertainty associated with the estimates of the HWP
contribution. The uncertainties can be divided into uncertainties associated with the methods as well as
parameter uncertainties.

METHOD UNCERTAINTIESIn the Tier 2 flux data method the basic model uncertainties are related to the assumption of FOD (Equation
2.8.5). A model is always a simplification of real world inducing method based uncertainties. The reason forusing decay models instead of just counting the inflow minus outflow from the HWP pools is that there are no
extensive and reliable statistics on the real discard flows (unlike on the inflows of semi-finished products), butsome knowledge on the service life of wood products. Although FOD decay is assumed to be a good proxy forthe decay of semi-finished products, other types of distributions could also be used to describe the true decay
process. However, the real world is even more complex. The service life and decay pattern of wood products are
not just a technical issue, but are also related to socio-economic factors (see Section 2.8.4.2). For instance, thedemand for wood products is likely to grow during economic booms resulting simultaneously in increasing
replacement of old HWP with new ones. Thus also discards of HWP correlate with their increasing consumption.
This is not reflected in the FOD pattern, where the discard rate is a constant fraction of the HWP pools in use
over time. As a result of FOD the annual change of carbon stock in HWP is steered too strongly by the
instantaneous production rate of HWP of domestic origin.
In the Tier 2 method another uncertainty is associated with the initialisation of the FOD model. Due to lack oflong historical data series on semi-finished HWP – for some countries data series are only available since theearly 1990s – the initial stocks of the HWP categories (C (t0)) are approximated by assuming that the stockchange was zero at the initial time. This proxy slightly overestimates the inherited emissions within the second
commitment period from the long-lived HWP categories sawnwood (with half-life of 35 years) and wood based
panels in case their stock in reality was growing at initial time, particularly when the calculation in Equation
2.8.5 is started only from the early 1990s. Depending on the accounting of HWP under Article 3 paragraph 4,
this could thus potentially increase the uncertainties of the HWP contribution provided especially from productswith high half-life values. In case the accounting approach for FM is based on a projected FMRL, however, thissource of uncertainty is of no relevance and consequence for the accounting of the HWP contribution.
Another model uncertainty is related to the number of HWP categories in the model. In the simplest Tier 2
method there are three HWP sub-pools for the main categories: sawnwood, wood-based panels and paper andpaperboard, each of which follows the FOD pattern but with different half-lives. The uncertainty could basicallybe lowered by introducing disaggregated sub-pools (e.g. for sawnwood) with differing half-lives based on their
156

This information includes methodological elements as used in the estimation of the HWP contribution to the FMRL andthe reporting during the second commitment period as defined in Annex II to Decision 2/CMP.8

2.132

Chapter 2: Methods for estimation, measurement, monitoring and reporting

end-use (cf. Table 2.8.3) or based on subcategories (e.g. wood-based panels disaggregated to particle board,
fibreboard etc., see Table 2.8.1).
In Tier 3, direct inventories of HWP in service (e.g. in the construction sector) could also be used to reduce theuncertainties associated with the flux data based method of Tier 2. The advantage of direct inventories is thatthey remove the need for idealised models with uncertain assumptions on decay pattern and whose verificationand validation could be questioned. The inventory method could in principle provide more robust and lessuncertain estimates for the carbon stock changes of the included HWP pools. Sequential direct inventories could
also be applied in the calibration of the flux-data models and their half-life parameters (see Box 2.8.1) and thus
reducing their uncertainties. However, the limitation of the method is that the statistics, if available, contains
only some major pools such as the housing sector of the reporting country: but there is no information e.g. on theuse of wood for furniture or packaging. Inventory methods cannot be applied for HWP in export markets by thereporting country either. Thus it must always be combined with flux data methods, inducing double-counting
risks of semi-finished and final products. Furthermore, it is applicable only in those few countries from which
relevant and sequential statistics are available.

UNCERTAINTIES OF ACT IVITY DATA
Uncertainties related to activity data on HWP from international databases (e.g. FAO) and the associateduncertainties of the estimates of the level of the HWP contribution could arise due to:Lack of time series: some Annex I countries were founded in the early 1990s and thus older activity data
might not be available (see above).



Definitional uncertainties (i.e. data provided do not conform to what has been requested). Removals data e.g.
tend in fact to be only commercial forestry operations or planned cuts, sawnwood production is being
provided in nominal, not solid m3, and pulp is only market (commercially sold) pulp.

The scope of data collection, as not all information is collected, particularly in the informal sector and fromsmall operators. This tends to affect especially the sawmilling industries, as limits to collect statistical data
might be linked to business volume or number of employees.

Double counting (e.g. final products counted in semi-finished commodities, such as cut paper being added topaper in rolls).

Reporting errors in providing correct data; that is numbers are put into the wrong category or incorrectly
processed by reporter or collecting agency.



Uncertainties associated with aggregate HWP commodities (e.g. wood-based panels): in general, the sum of
the subcategories accords with the value for the aggregate commodities, but some categories may
underreport because of missing subcategories (e.g. missing data on veneer sheets result in an underestimate
for wood-based panels).

Concerning data on the feedstock of production of semi-finished HWP categories (i.e. industrial roundwood andwood pulp as proposed in Section 2.8.1.2), uncertainty could be caused by unreported sources, by-product use ortrade data.
The semi-finished HWP categories (i.e. sawnwood, wood-based panels and paper and paperboard) are also
subject to the above mentioned conditions. An overall estimate of these factors results in an estimateduncertainty of the reported values between -25% to +5% (based on the authors’ expert judgement).
All of these sources of uncertainty together tend to result in an under-reporting of HWP commodity data ininternational databases, that is, actual figures are usually higher. As this is particularly the case in roundwood (i.e.
wood-removals, see Figure 2.8.2) the allocation of the HWP categories to forest activities as described in Section
2.8.1.2 should be fairly conservative.
Further uncertainties associated with activity data are caused by conversion factors. The provided conversion
factors (see Table 2.8.1) are highly generalized and reflect averages which may not correct for species andspecific items.
In order to reduce uncertainties around conversion factors for carbon, Parties are encouraged to use subcategories under Tier 2 (see Section 2.8.3.2) or use a Tier 3 approach where they can make use of commodity
specific conversion factors linked e.g. to various wood species of the particular items (see Section 2.8.4.2).
Aside from reviewing the data to check if it fits with a general understanding of the forest products supply in acountry, it is most useful for reducing the uncertainties relating to activity data to cross-check if the amount ofdomestic production of HWP categories balances with the available supply of wood. Other validation methods
could include a review of trade unit values and determination of per capita apparent consumption.

2.133Chapter 2: Methods for estimation, measurement, monitoring and reporting

UNCERTAINTIES ASSOCIATED WITH EMISSION F ACTORS (SERVICE AND HALF -LIFE ESTIMATES)The half-life parameters are in general the most uncertain part of the Tier 2 calculation method. The scientificevidence behind the default values given in Table 2.8.2 is not robust157. Nor do they present a conservative
estimate that would rather lead to underestimation than overestimation of the carbon stock changes in HWP. For
decreasing uncertainty, countries are strongly encouraged to adjust the Tier 2 half-life parameters by calibrating
the FOD model either a) with direct inventories of HWP in use, or b) with market information as shown in Table
2.8.3. The application of stock inventory information, however, due to the lack of appropriate statistics is notpractical for most countries. Furthermore, it does not cover export markets of the reporting country. Two specificcalibration studies (Pingoud, et al. 2001, Statistics Finland 2011) indicate that the true half-life of sawnwood andwood-based panels in Finland is likely to be much shorter than the default half-lives (Table 2.8.2). Thus, in thisparticular case the use of default half-lives would substantially overestimate the HWP pool in use. The results ofsuch calibration studies could possibly be generalised to obtain better estimates for default half-lives.
Even though the uncertainty associated with Tier 2 estimates using default data could be high, working throughsuch estimates can be the first step in identifying ways to improve them. Initial improvements can be made using
country-specific data with country-specific half-lives instead of the default half-lives in Tier 3.
To decrease uncertainties in Tier 3 Parties are encouraged to use direct inventories of HWP in use, to develop
more realistic decay patterns for HWP and use more sub-pools in case transparent information is available.
However, the model calibration procedure to direct HWP inventories requires in practice a model with very few
adjustable parameters.

2.8.7

Quality Assurance/Quality Control

Detailed steps to improve estimates of HWP activity data are already described in detail for Tiers 2 and 3
methods in Sections 2.8.3 and 2.8.4, and also in Section 2.8.6 (as it relates to uncertainties). These steps include
the use of country-specific data and half-lives for Tier 2 methods (Sections 2.8.3.1.and 2.8.3.2) and theapplication of potential steps to derive improved Tier 3 estimates (Sections 2.8.4.1. and 2.8.4.2). Therefore, thissection does not provide a separate, detailed sub-section on Quality Assurance and Quality Control.

CROPLAND MANAGEMENT

2.9.1

Definitional issues and reporting requirements

Cropland Management (CM) is the system of practices on land on which agricultural crops are grown and on
land that is set-aside or temporarily not being used for crop production158. CM includes all lands under annual
and perennial crops, and all fallow lands set at rest for one or several years before being cultivated again.
It is good practice to include, in land subject to CM, all the lands in the Cropland category of Section 3.2,
Chapter 3, Volume 4 of the 2006 IPCC Guidelines, namely cropped land, including rice fields, except for land
reported under deforestation. It is also good practice for countries to specify how land subject to CM isdistinguished from other activities under the KP using the guidelines provided in Section 3.3, Chapter 3, Volume
4 of the 2006 IPCC Guidelines, together with the guidance presented here.
Perennial crops can include orchards, vineyards and plantations such as cocoa, coffee, tea and bananas. In thefirst commitment period, some countries included certain types of perennial crops (e.g. fruit orchards, Christmas
tree plantations) within CM even if the cover met the thresholds for forest. For consistency and to achievetransparency in reporting, it is good practice in the second commitment period for those countries to ensure that
double-counting with FM is avoided and to document how consistency is achieved with KP activities reported
previously. Areas having tree cover, such as orchards or shelterbelts that were established after 1990 and meetthe definition of a forest can qualify as AR and, in such cases, are included under AR.. Further guidance about
the inclusion of orchards and other tree crops under CM is provided in Section 1.2 of this supplement.
Rice paddies are also included under Cropland, but associated CH4 and N2O emissions are reported under
Agriculture in reporting under the UNFCCC and KP and hence not under this activity. Cropland that is
temporarily used for grazing or perennial fodders can also be included under CM. Set-aside lands are included in
CM when they return, or are expected to return, to cropping after some period of time. Countries are encouraged
to develop consistent criteria for defining set-aside lands and their allocation among activities.
The aim of the reporting exercise is to identify and report trends and systematic changes in the carbon stocks
resulting from changes in CM practices over time. The premise is that changes in soil carbon stocks result fromchanges in CM practices that influence the rates of either additions to, or losses of, soil organic carbon. However,
CM is not the only driver of changes in carbon stocks. Natural phenomena, such as weather, wild fire, abnormal
flooding or prolonged drought can also influence the rate of carbon gains and losses in cropland, and if theireffects are large enough, can mask the carbon trend or signal resulting from CM practices, as elements of CM
activities. Countries are encouraged to use higher tier methods (Tier 2 or Tier 3) to develop emissions
coefficients or models to represent the effects of management practices rather than those of inter-annual
variability and natural disturbances on carbon stocks. More information about how to use higher tier methods toestimate management effects on CM emissions and removals is provided in Sections 2.3.6 and 2.9.4 of this
supplement.
The main processes involved in estimating emissions and removals are stratification of croplands followed byestimation of emissions and removals resulting from changes in land management within each stratum. Inventory
compilers first identify croplands and subdivide the total cropland area into strata that represent consistentclasses of land, biophysical characteristics and management practices for the base year and each of the years in
the commitment period (see Section 2.9.3 of this supplement and examples in Table 5.5, Chapter 5, Volume 4 ofthe 2006 IPCC Guidelines). CM practices that affect soil carbon emissions and removals include tillage practices,
rotation and cover crops, fertility management, plant residue management, erosion control and irrigation
management (IPCC, 2000). The second main process is to estimate how the types of and changes in management
practices influence emissions and removals over time, using methods discussed in Section 2.9.4 of this
supplement.
It is good practice that Parties ensure consistency in methods applied for estimating emissions and removals
from KP activities, e.g. methods across different practices covered under Articles 3.3 and 3.4 and management
practices occurring on land that was deforested should be consistent with methods used for the surrounding CM
practices.
It is good practice to apply the following steps for estimating emissions and removals from CM:
STEP 1: Define CM and apply the definition in a consistent manner over time, including in the base year.
Croplands such as vineyards and orchards that meet the definition of forest can be included under CM or FM, but

not under both. It is important to apply the definitions consistently over time, even though data and informationfrom the past may be of lower quality.
STEP 2: Identify the land under CM using the Approaches described in Section 3.3, Chapter 3, Volume 4 of the2006 IPCC Guidelines and the appropriate sections in this supplement.
STEP 3: Distinguish between the two subcategories of CM: mineral soils and organic soils.
STEP 4: Select the appropriate tier and methodology for estimating emissions and removals based on key
category analysis, including assessment of significant subcategories (Section 4.2, Chapter 4, Volume 1 of the2006 IPCC Guidelines and Figure 2.9.1 of this supplement), and available data. For mineral soils, this includes
methodologies for monitoring land management activities and change.
STEP 5: Stratify by climate. For mineral soils, also stratify by other relevant biophysical characteristics of theland, such as soil type, and CM practices (see Section 2.9.3 of this supplement).
STEP 6: For each stratum, estimate the CM emissions and removals for the base year and each year in thecommitment period using Tier 1, Tier 2 or Tier 3 methods (see Section 2.9.4 of this supplement). Total emissions
are the sum of emissions and removals from mineral soils and organic soils.
Methods to identify land under CM with adequate disaggregation may include:National land use and management statistics: in most countries, the agricultural land base including
croplands is surveyed regularly, providing data on distribution of different land uses, crops, tillage practiceand other aspects of management, often at sub-national or regional level. These statistics may originate, inpart, from remote sensing methods.

Inventory data from a statistically based, plot-sampling system: land use and management activities aremonitored at specific permanent sample plots that are revisited on a regular basis.

2.9.2

Base year

Under Article 3.4 of the KP, emissions and removals resulting from CM are estimated using a net-net accounting
approach (as are all elective activities under Article 3.4). Net-net accounting requires that GHG emissions andremovals are estimated for the base year and each year of the commitment period159. This entails determining thetotal area under CM for the base year and for each year of the commitment period and estimating carbon
emissions and removals resulting from changes in land management for those areas. Guidance for estimating thecorresponding non-CO2 GHG emissions from Cropland for 1990 are covered in Chapters 10 and 11, Volume 4of the 2006 IPCC Guidelines (see the text on non-CO2 gases in Section 2.9.4 of this supplement).
For most Parties with commitments under the KP, the base year is 1990. Under the provisions of Article 4.6 of
the UNFCCC and Article 3.5 of the KP, however, Parties with economies in transition (EITs) are granted someflexibility on the level of historical emissions chosen as a reference.
If the area under CM changes between the base year and the commitment period, e.g. due to AR or land moving
into another elected activity under the KP, this may lead to estimates on the basis of moving land (that is,
subtraction of stock changes on a land base that changes in size over time), as illustrated in the example in Box
2.9.1. In principle, once land has been reported under any Article 3.3 or 3.4 activity during a commitment period,
it must continue to be reported. For CM, the guidance provided in the GPG-LULUCF (Box 4.2.8) acknowledges
that some of the area of the activity in the ‘base year only’ may no longer be reported under that activity in thereporting year. Where this area is not transferred to another reported activity the associated emissions andremovals will be accounted as zero in that year. In order to achieve transparency in reporting, it is good practice
to describe the consequences of this exclusion on reported emissions and removals.

159

Net-net accounting refers to the provisions of paragraph 10 of the Annex to Decision 2/CMP.7 contained in document
FCCC/KP/CMP/2011/10/Add.1, p.14.

AN EXAMPLE OF CROPLAND MANAGEMENT AREAS IN BASE YEAR
AND IN THE COMMITMENT PERIOD (NET-NET ACCOUNTING)

In this example the area under CM in the base year expands to a larger area in the reporting year
during the commitment period. Some of the area was under CM in both the base year and during
the reporting period (a). Some of the area under CM in the base year is no longer under CM in thereporting year (b). There are also areas under CM in the reporting year that were not under CM in
the base year (c). Area (D) is under CM, but was subject to Deforestation (D) which takes
precedence. Area (e) has been converted to cropland, but remains under FM under the CEFC
provision. Under the KP, the emissions and removals in areas (a) + (b) in the base year arecompared to emissions and removals in areas (a) + (c) – (D) – (e) in the reporting year.

Historical data on land use and management practices in 1990 (or the appropriate year(s)) and in years prior to1990 are needed to establish the 1990 base year net emissions and removals of soil carbon from CM. The Tier 1
method described in Section 5.3.3, Chapter 5, Volume 4 of the 2006 IPCC Guidelines for mineral soils assumes
that a change in land use or management has an impact on carbon emissions and removals for a duration of 20
years; hence, under this tier and if a change in management has taken place since 1970, it is good practice tocalculate the net carbon stock change in 1990 taking this change into account. If area and activity data are
available for 1970 to 1990, the net carbon stock change during the 1990 base year can be established using thedefault carbon emission and removal factors. For organic soils, the inventory time period is treated the same as
long-term cropped organic soils. Tier 1 emission factors are provided in Table 5.6, Chapter 5, Volume 4 of the2006 IPCC Guidelines and updated by the Wetlands Supplement (see Footnote 1, Section 2.1 of this supplement).
The duration of impact of management practices on soil organic carbon may differ from the 20 years used as adefault to reach a new equilibrium. If data on the duration of impact are available, it is good practice to use theappropriate time period, based on country-specific data and measurements (see Tier 2 and Tier 3 approaches in
Section 2.9.4 of this supplement).
If area and activity data are not available for 1970 to 1990, countries can establish the base year 1990 carbon
stock change using the most appropriate time series to estimate the 1990 value, in a manner consistent withguidance provided in Section 5.3, Chapter 5, Volume 1 of 2006 IPCC Guidelines. It is good practice to use atime period equivalent to 20 years that includes 1990 or as close to 1990 as possible.
The results of accounting on a net-net basis depend not just on changes in land management practices, but also
partly on when the base year and commitment period years fall within the temporal dynamics of carbon
sequestration processes. As noted above, carbon stock changes resulting from land use and land managementchanges on mineral soil tend to persist for about 20 years, after which the carbon levels approach a new2013 Revised Supplementary Methods and Good Practice Guidance Arising from the Kyoto Protocol

2.137

Chapter 2: Methods for estimation, measurement, monitoring and reporting

equilibrium carbon stock. The rate of carbon sequestration in mineral soil following a change in management inwhich carbon additions increase or carbon losses decline tends to be high in the first decades and then declines
over time, as illustrated in Figure 2.9.2.

2.9.3

Choice of methods for identifying lands subject toCropland Management activities

General guidance on consistent representation of lands is provided in Chapter 3 of the 2006 IPCC Guidelines
with additional guidance about identification of lands subject to CM provided in Sections 1.1, 1.2, 2.1, and 2.2 ofthis supplement.
According to Decision 2/CMP.8160, the geographical location of the boundaries of the area that encompass land
subject to CM needs to be reported annually, along with the total land areas subject to this activity. The
geographical location of boundaries may include a spatially-explicit specification of land subject to CM, but does
not have to. Instead, the boundaries of larger areas encompassing smaller lands subject to CM may be provided,
along with estimates of the area subject to CM in each of the larger areas. In either case, the land subject to CM
and the management thereon need to be tracked through time because the continuity and duration of management
practices and changes affects carbon emissions and removals.
It is good practice to follow continuously the management of land that is subject to CM. This could be achievedby tracking land subject to CM from 1990 until the end of the commitment period (e.g. see Section 2.9.2 of this
supplement). Alternatively, countries could develop statistical sampling techniques, consistent with the advice inAnnex 3A.3, Chapter 3, Volume 4 of the 2006 IPCC Guidelines, which allow the transitions of management
practices on lands subject to CM to be determined (see also Section 2.4.1 of this supplement).
At the national level, it is good practice, when developing a sampling strategy, to identify criteria that could be
used to set up a stratified sampling scheme. Stratification criteria may include relatively static biophysicalcharacteristics - such as climate and soil type, typical crop rotation systems, as well as management practices that
tend to be more dynamic drivers of change in emissions and removals from carbon pools. Guidance on
stratifying land to match data needs for estimating emissions and removals is provided in Section 3.3.2, Chapter
3, Volume 4 of the 2006 IPCC Guidelines.
Management factors that may be useful in establishing a national stratification scheme include:

Degree of soil disturbance (e.g. tillage frequency and intensity)Level of input of crop biomass or organic amendment

Crop rotation system

Frequency of fallow practices

Inclusion of woody biomass in the farming system (e.g. shelterbelts, orchards, other perennial plantations)

Temporary use for livestock grazing

At higher tiers further subdivision of the CM area may be necessary.
For all resulting subcategories under CM, the areas derived from the conversion of forests (i.e. D) since 1990
need to be tracked separately as these will be reported as lands subject to D under Article 3.3 of the KP.
Emissions and removals resulting from conversion of FM to CM due to the harvest and conversion of forest
plantations to non-forest land could be reported under CEFC according to Decision 2/CMP.8161.

2.9.4

Choice of methods for estimating carbon stockchanges and non-CO 2 GHG

For CM, the 2006 IPCC Guidelines give methodological guidance for estimating:

Annual changes in carbon stocks of above- and below-ground biomass

Annual changes of dead organic matter (DOM; dead wood and litter)

Section 2.3.6 of this supplement provides guidance on the choice of methods and for identifying whether CM is a
key category. If CM is a key category, the inventory compiler should determine which subcategories such as
mineral soil, organic soil or above-ground biomass, are significant. Section 1.3.3, Chapter 1 in Volume 4 of the2006 IPCC Guidelines suggests ranking subcategories according to their contribution to the aggregate key
category. It is good practice to focus efforts towards methodological improvements of these significant
subcategories.
Decision 2/CMP.7162 specifies that a Party may choose not to account for a particular pool in a commitment
period if transparent and verifiable information is provided that demonstrates that the pool is not a source.
Requirements for reporting excluded pools and documenting that a pool is not a source can be found in Section
2.3.1 of this supplement. It is possible that Parties will use different tiers to prepare estimates for individual
subcategories (e.g. changes in organic carbon stocks in mineral soils and emissions and removals in organicsoils). Since different methods may yield different estimates, each with different levels of uncertainty, it is goodpractice to use the same tier and methodology for estimating carbon emissions and removals from eachsubcategory and pool for the full time series, for example, in the base year and during the commitment period.
Methods for estimating Cropland CO2 emissions and removals or carbon stock changes for the base year and thecommitment period are provided in Chapters 2 and 5, Volume 4 of the 2006 IPCC Guidelines. The following
sections of this supplement highlight aspects of these methods specific to the KP.

2.9.4.1

B IOMASS AND DEAD ORGANIC MATTER

For perennial crops (e.g. trees, shelterbelts and orchards), carbon stock changes in biomass and DOM pools
should be estimated unless the Party to the KP chooses not to report on a certain pool and provides verifiable
information that carbon stocks are not decreasing.
For carbon stock changes in biomass resulting from changes in CM, it is good practice for Parties to use thedecision tree in Figure 2.9.1 to identify the appropriate tier to estimate carbon stock changes in biomass andDOM under the KP. Relevant methods for estimating carbon stock changes in above- and below-ground biomass,and DOM can be found in Sections 5.2.1 and 5.2.2, Chapter 5, Volume 4 of the 2006 IPCC Guidelines,
respectively. Default coefficients for above-ground woody biomass and harvest cycles in cropping systems
containing perennial species are provided in Table 5.1; potential C storage for agroforestry systems in different
eco-regions of the world are provided in Table 5.2; default above-ground biomass for various types of perennial
croplands are given in Table 5.3 of Chapter 5, Volume 4 of the 2006 IPCC Guidelines. Box 2.9.2 is an exampleof how to estimate carbon stock changes for biomass for fruit orchards.

EXAMPLE OF ESTIMATING BIOMASS CARBON CHANGES FOR FRUIT ORCHARDS

Canada chose to consistently include the orchards of fruit trees as a practice within CM. The
general Canadian orchard recommendations are to replace about 5% of the orchard each year.
Therefore it was assumed that the orchard consisted of an even representation of all age classes
from 0 to 20 years. With this constant tree removal and addition to the orchard area, the gain in
carbon from growing trees would equal the loss of carbon from removed trees. The loss of carbon
from removed trees was assumed instantaneous. Because of intense pruning, above- and belowground carbon stocks of fruit trees were considered to increase linearly with age. The averagecarbon stock of an orchard was therefore the equivalent of 10-year old fruit trees. Any conversionof orchards to other land uses was assumed to result from drivers other than old age class structure.
Consequently, the loss of orchard was the equivalent of losing an average orchard of carbon stocks
equivalent to an orchard composed of entirely 10-year old trees. New orchard areas were assumed
to accumulate carbon stock linearly for 10 years, up to the amount of a 10-year old tree. After new
orchard area had existed for 10 years, it was assumed that carbon stock removal equalled carbon
stock gain because of regular tree removal and pruning so there is no further gain or loss of carbon.

2.9.4.2

S OIL CARBON

In most croplands, the main carbon flux associated with changes in land use and management for CM activities
is from changes in organic carbon in soil. Chapter 5, Volume 4 of the 2006 IPCC Guidelines identifies two
sources or sinks of CO2 from agricultural soils:Net changes in soil organic carbon associated with changes in land use and management on mineral soil;Emissions of CO2 from cultivated organic soils (updated by the Wetlands Supplement).

Total annual emissions and removals of CO2 are calculated by summing emissions and removals from the two
subcategories (mineral and organic soils) using methods outlined in Chapter 5 and Equation 2.24, Chapter 2,
Volume 4 of the 2006 IPCC Guidelines and updates in the Wetlands Supplement (see footnote 1, Section 2.1 ofthis supplement).

MINERAL SOILS
Methods for estimating mineral soil carbon stock changes resulting from changes in CM fall under one of threemethodological tiers described in Sections 1.3.2 and 1.3.3, Chapter 1, Volume 4 of 2006 IPCC Guidelines.

Methods for estimating carbon stock changes in mineral soils
It is good practice to use the decision tree in Figure 2.9.1 to decide which tier to use for estimating carbon stockchanges associated with changes in CM practices under the KP. It is good practice to use Tier 2 or Tier 3
methods for reporting carbon stock changes from mineral soils if CM is a key category and mineral soils are asignificant subcategory under CM. It is good practice to follow continuously the CM practices from the baseyear through the commitment period as described in Section 2.9.3 of this supplement. For discussion of how toestimate the CM area, see Section 1.3 of this supplement.

Tier 1The Tier 1 method for estimating carbon stock changes in mineral soils is described in Section 2.3.3.1, Chapter 2,
and Section 5.2.3, Chapter 5 in Volume 4 of the 2006 IPCC Guidelines. This guidance assumes a new
equilibrium soil organic carbon stock is achieved after 20 years in a practice.
Section 5.2.3.4, Chapter 5 and Chapter 2 in Volume 4 of the 2006 IPCC Guidelines outline the steps for
estimating average annual rates of carbon stock change of in mineral soils of croplands using the default
reference carbon stocks (Table 2.3), carbon stock change factors (Table 5.5) and Equation 2.25. The Tier 1
method can be used to estimate carbon flux resulting from changes in management practices across a range oftemperature and moisture regimes and soil types. Box 2.9.3 (this supplement) provides an illustration of how toapply Tier 1 to estimate carbon stock changes for CM practices that are not continuous over time.

Tier 2The Tier 2 method also uses the methodology described in Chapter 5, Volume 4 of the 2006 IPCC Guidelines,
but the default relative carbon stock change factors are replaced with region- or country-specific values. It isgood practice to obtain region- or country-specific emissions factors from literature values, long-term
experiments or the local application of well-calibrated, well-documented soil carbon models. Region-specificdata for soil carbon content (such as that available from national soil inventories) can also be used.
To ensure that region-specific carbon stock change factors better represent actual emissions and removals in agiven region than default relative carbon stock change factors, rigorous criteria demonstrating that the more
specific factors do not lead to under- or overestimation of the soil carbon stock change should be applied.
Region- or country-specific factors should be based on verified soil carbon model estimates or measurementsthat are, in addition to being documented in accessible publications, conducted frequently enough, over a longenough time period and with sufficient spatial density to reflect variability of the underlying biochemical
processes.
For Tier 2 approaches, it is good practice to replace the 20-year default with a value that reflects national orregional information about the duration of practices to reach a new equilibrium in soil carbon stocks.
An asymptotic model can also be fitted to data of soil carbon stock changes (Figure 2.9.2). Using this method,
the higher carbon factors applied immediately after a land-use or management change gradually diminish, so thatstock changes are not underestimated soon after a change (‘a’ in Figure 2.9.2), nor overestimated as the soil
approaches the new equilibrium (‘b’ in Figure 2.9.2).

At Tier 2, default factors associated with a land-use or management change can be replaced by more detailed
relationships between the intensity of a practice (e.g. the amount of an organic amendment applied to the soil)
and an annualized change in emissions or removals in the soil carbon pool. For example, in Europe, Smith et al.
(2000) developed such relationships [e.g. average annualized soil carbon stock change (tonnes C ha-1 yr-1) =0.0145 x amount of animal manure (tonnes d. m. ha-1 yr-1) added; recalculated from data in Smith et al. (1997); r2= 0.3658, n = 17, p < 0.01]. Similar relationships could be derived from long-term data for different soil types indifferent climatic regions. Alternatively, well-calibrated and well-evaluated models of soil carbon change e.g.
CENTURY (Parton et al., 1987), RothC (Coleman and Jenkinson, 1996) could be used to generate either stockchange factors, or the intensity relationships described above, for different soils in different climatic regions.
Rigorous criteria should be applied in order to ensure emissions and removals are neither under- noroverestimated. It is good practice that stock change factors be based on experiments sampled according to theprinciples set out in Section 2.3.3, Chapter 2, Volume 4 of the 2006 IPCC Guidelines and to use the experimental
values if they are more appropriate than the default values for region and management practice. Factors based onmodels should only be used after the model has been tested against experiments such as those described above
and any model should be widely evaluated, well-documented and archived. It is good practice to provide
confidence limits or uncertainty estimates associated with regional, country-specific or local stock change factors.

Chapter 2: Methods for estimation, measurement, monitoring and reporting

Tier 3Tier 3 methods generally encompass a range of methodologies that are more elaborate than Tier 2. Tier 3
methods are usually based on sophisticated modeling techniques and are often linked to geographical databases.
Compared with the static matrix used at Tiers 1 and 2, Tier 3 can represent the management history of a land thatfacilitates calculation of soil carbon changes resulting from multiple changes in management practices over time
including rotational changes in land use. Like Tier 2 methods, Tier 3 methods can also take into account a longer
time period to reach equilibrium than 20 years. Current computing power makes it possible to link spatiallydisaggregated (stratified) land data to management practice data. Using these analytical systems, carbon stockchanges can be estimated over time by linking equations describing the rate of change in soil carbon under
specific management practices with carbon content, initialised by existing data and cross-checked periodically.
Tier 3 methods can also be based on repeated statistical sampling consistent with the principles set out in Annex
3A.3, Chapter 3, Volume 4 of the 2006 IPCC Guidelines. The sampling protocol should be of sufficient density
to capture the soil types, climatic regions and management practices.

ILLUSTRATION OF ESTIMATING CARBON STOCK CHANGES FOR DISCONTINUOUS CROPLAND MANAGEMENT
PRACTICES

Many inventory compilers need to use Reporting Method 1 [non-spatially explicit aggregate
statistics of total areas of practices (see Section 2.2.4 of this supplement)] for representing areas of
CM practices due to a lack of available activity data. Using non-spatial data, it is not possible todiscern if practices are continuous over time. This discontinuity in practice is expected to affectsoil carbon stock change. This is a particular concern for no-till (NT) practices because it is notuncommon for there to be occasional tillage within NT cropping systems. The amount ofaccumulated additional carbon that is reduced from single tillage on land under long-term NT
ranges from 0-11% (VandenBygaart and Kay, 2004; Koch and Stockfisch, 2006; Conant et al.,2007; Quincke et al., 2007). In some situations, however, more than a 30% loss of accumulated
additional soil carbon occurs from single plowing of land that had been in long-term NT(VandenBygaart and Kay, 2004).
Tier 1 estimation methods can be applied for discontinuous CM practices when using Reporting
Method 1. To illustrate, consider a parcel of land under NT with occasional full tillage (FT) andhaving consistent medium input. From Table 2.3 in Chapter 2, Volume 4 of the 2006 IPCC
Guidelines, the reference soil organic carbon stock is 34 Mg ha-1 and FLU=0.69. This land parcel
undergoes FT in years 5, 11, 14 and 18. As is necessary when using Reporting Method 1, eachdecrease of NT is assumed to occur on land that has been under NT for at least 20 years and eachincrease on land that has been under FT for at least 20 years. The carbon stock change is also
assumed to continue for 20 years after a change in tillage is identified as a change in net areas
under FT and NT. Following guidance in Chapters 2 and 5, Volume 4 of the 2006 IPCC
Guidelines, the effect of carbon change is calculated using Formulation A (Box 2.1 in Chapter 2)of annual soil organic carbon stock change (applying Equation 2.25 in Chapter 2 and Table 5.5 in
Chapter 5). As shown in the figure below, the calculated cumulative ΔCmineral is lower withoccasional FT than for continuous NT; discontinuous NT is 80% of carbon stock change ofcontinuous NT at year 20 until that land has been under NT for 20 years continuously (i.e. year38). This is consistent with understanding of the effect of intermittent tillage on soil organic carbon
on land otherwise under NT. This example illustrates that Tier 1 methods can be applied for
discontinuous practices embedded within the data of net areas under different CM practices.
If, for the example presented, spatially explicit data were available in order to apply Reporting
Method 2, the Tier 1 cumulative C stock change would be calculated using Formulation B (Box
2.1 in Chapter 2, Volume 4 of the 2006 IPCC Guidelines). This estimate is shown in the figure
below. As expected, in both cases of discontinuous NT, the estimated soil organic carbon changes
are lower than those for continuous NT during the period of discontinuous NT.
If there are spatially explicit data on CM practices, it is good practice to use Reporting Method 2.
If there are available data on discontinuity of CM practices and on the effect of discontinuity inpractice on soil organic carbon change, it is good practice to use higher tier methods.

The carbon emission and removal factors used at each tier are described briefly in the following sections.

Tier 1
At Tier 1, average annualized carbon stock changes in mineral soils are calculated from default values bydividing the 20-year stock change by 20, as formulated in Equation 2.25 in Chapter 2, Volume 4 of 2006 IPCC
Guidelines. Default reference (under native vegetation) soil organic carbon stocks (SOCREF) for mineral soils andfull details of default relative stock change factors for land use (FLU), input (FI) and management (FMG) factors(over 20 years) can be found in Table 2.3 (for SOCREF), Chapter 2 and Table 5.5 (for FLU, FI and FMG), Chapter 5,
Volume 4 of the 2006 IPCC Guidelines, respectively. Management practice is assumed to influence stocks to adepth of 30 cm. For a summary of the steps, see Sections 2.3.3 and 5.2.3.4 of Chapters 2 and 5, Volume 4 of the2006 IPCC Guidelines.

Tier 2
At Tier 2, some or all of the default values for carbon stock change (Tier 1) are replaced by values shown to be
more specific to account for national or regional soil carbon stock changes. These new values may be based onliterature values, measured changes in carbon stocks, carbon models, or a combination of these sources. (See
‘Choice of management data for mineral soils’ below for examples). It is good practice to derive relative stockchange factor values for a higher resolution classification of management, climate, and soil types if, based on an
empirical analysis, there are significant differences in the stock change factors among more disaggregatedcategories. Reference soil organic C stocks (SOCREF) can also be derived from country-specific data in a Tier 2
approach. Additional guidance is provided in Section 2.3.3.1, Chapter 2, Volume 4 of the 2006 IPCC Guidelines.

Tier 3For mineral soils, Tier 3 approaches may use dynamic models and detailed soil C inventory measurements as thebasis for estimating annual stock changes. Tier 3 methods may involve the use of country-derived carbon stockchange factors which may be calculated using sophisticated models. The carbon models used for Tier 3 are
generally more complex than those of Tier 2, taking into account soil (e.g. clay content, chemical composition,
parent material), climate (e.g. precipitation, temperature, evapotranspiration), and management factors (e.g.
tillage, carbon inputs, fertility amendments, cropping system). Good practice requires that the models becalibrated using measurements at benchmark sites, and that selected models and assumptions used are describedtransparently.
In all cases, rigorous criteria should be applied to ensure that any change in carbon stocks is neither under- noroverestimated; models used to estimate carbon stock changes should be well-documented and evaluated using
reliable experimental data for conditions and practices to which the models are applied. It is good practice toprovide confidence limits or uncertainty estimates according to the descriptions in Sections 5.2.3.5 and 5.3.3.5 in
Chapter 5, Volume 4 of 2006 IPCC Guidelines. Default carbon stock change factors may also be replaced byvalues that are generated as part of national or regional carbon accounting systems (see Section 2.9.3 of this
supplement).

Choice of management data for mineral soils
Area data on land use and practices can be available according to either Reporting Method 1 or 2 as described in
Section 2.2 of this supplement. Management data required for each of the three tiers are outlined briefly below.

Tier 1
Following Volume 4 of the 2006 IPCC Guidelines, land management change is assumed, by default, to have an
impact for 20 years. If area and activity data are available for the period 20 years prior to the base year, net
carbon emissions and removals for the base year can be established using the default carbon stock change factors
described above. The changes in management practices at Tier 1 are the same as those given in the 2006 IPCC
Guidelines: differing cultivation, tillage, and input levels. Within these specific management changes, activities
are defined semi-quantitatively, for example: low, medium or high inputs without manure; high inputs withmanure; full, reduced and no-till systems. Area data may be obtained from international data sets (e.g. FAOWorld Census of Agriculture, FAOSTAT), though some of these sources lack the spatial explicitness needed forreporting and may only be helpful for cross-checking data. If area and activity data are available for 1970 and
1990, a 1990 baseline net carbon stock change can be established using the default carbon stock change factors
described above and the area and activity data for 1970 and 1990.
If area and activity data are not available for 1970 to 1990, countries can establish the 1990 carbon stock changeusing the most appropriate time series to estimate the 1990 value, in a manner consistent with guidance provided
in Section 5.3, Chapter 5, Volume 1 of the 2006 IPCC Guidelines. It is good practice to use a time period
equivalent to 20 years that includes 1990 or as close to 1990 as possible.

Tier 2Tier 2 approaches are likely to involve a more detailed stratification of management systems than in Tier 1 if
sufficient data are available. This can include further subdividing annual cropping input categories (e.g. low,
medium, high, and high with amendment), rice cultivation, perennial cropping systems, and set-asides. It is goodpractice to further subdivide default classes based on empirical data that demonstrates significant differences insoil organic C storage among the proposed categories. In addition, Tier 2 approaches can incorporate a finer
stratification of climate regions and soil types. Tier 2 methods may require area descriptions of higher resolution
than those in Tier 1. In any case, rigorous criteria should be applied so that emissions in the base year andremovals in each year of the commitment period are neither under- nor overestimated.

Tier 3
Management data used in the more complex Tier 3 methodologies need to be consistent with the level of detailrequired by the model. It is good practice to use management data at a spatial resolution appropriate for themodel, and to have, or be able to estimate reliably, quantitative measures of the management factors required by
the model.

ORGANIC SOILS
It is good practice to use the decision tree in Figure 2.9.1 to decide which tier to use for estimating emissions andremovals in organic soils associated with changes in CM under the KP. It is good practice to use Tier 2 or Tier 3
methods for reporting emissions and removals in organic soils if CM is a key category and organic soils are asignificant subcategory under CM.

Methods for estimating CO 2 emissions and removals from organic soils
When organic soils are converted to or managed for agriculture, they are typically drained, tilled and fertilised,resulting in on-site CO2 emissions to the atmosphere as well as waterborne carbon losses that lead to off-site CO2
emissions. Countries may use methods of different tier levels for on-site and off-site CO2 emissions from organicsoils. The rate of CO2 release will depend on, inter alia, climate, the degree of drainage, nutrient status andpractices such as fertilisation and liming. Oxidation of organic material results in land subsidence and CO2
emissions will continue until the organic soil layer is depleted or until further lowering of the drainage base is nolonger feasible. Drained organic soils under CM can be rewetted while remaining under CM. Guidance on
rewetting and drainage of organic soils can be found in Section 2.12 of this supplement. The Wetlands
Supplement contains updated and new methodological guidance for estimating GHG emissions and removals
from organic soils (see Footnote 1, Section 2.1 of this supplement).

Tier 1The Tier 1 approach is described in Section 2.3.3 of Chapter 2 and Section 5.2.3.4 of Chapter 5, Volume 4 of the2006 IPCC Guidelines and updated by Chapters 2 and 4 of the Wetlands Supplement, which include guidance foron-site CO2 (including peat fires), off-site CO2 and CH4 from drained organic soils and drainage ditches (seeFootnote 1, Section 2.1 of this supplement).

Tier 2
If country- or region-specific data is available on CO2 emissions from organic soils, it is good practice to use
these instead of Tier 1 defaults. Any data used should be shown to be more reliable, and representative of thenational conditions, than defaults. It is good practice to use a finer classification for climate and management
practices, such as drainage classes, if there are significant differences in measured carbon loss rates among the
proposed classes.

Tier 3
A Tier 3 approach may involve estimation of CO2 and non-CO2 GHG emissions in an integrated way. However,the non-CO2 emissions should be reported under Agriculture (see Section 2.4.4.2 of this supplement), anddouble-counting and omissions should be avoided. It is good practice to use models that are calibrated using
measurements at benchmark sites, and to describe transparently the models and assumptions used.

Choice of carbon emission and removal factors for organic soils
Tier 1The Tier 1 default emission and removal factors are provided in Table 5.6, Chapter 5, Volume 4 of the 2006
IPCC Guidelines and updated by Chapters 2 and 4 of the Wetlands Supplement for on-site CO2 (including peat
fires), off-site CO2 and CH4 from drained organic soils and drainage ditches (see Footnote 1, Section 2.1 of this
supplement).

Tier 2For organic soils, it is good practice to replace the default values with country- or region-specific factors. It isgood practice to use country- or region-specific emission and removal factors derived from measurements orexperiments within the region that are well-designed and employ adequate sampling and coverage. It is good

2.146

2013 Revised Supplementary Methods and Good Practice Guidance Arising from the Kyoto Protocol

Chapter 2: Methods for estimation, measurement, monitoring and reporting

practice to provide confidence limits or uncertainty estimates associated with any country- or region-specificemission and removal factors.

Tier 3For organic soils, CO2 emissions and removals may be estimated using a model or measurement based approach.
Time-dependent emission and removal factors capture more accurately the effects of land-use and managementchanges. Dynamic models could capture the influence of (changes in) land use and management practices,
particularly the effect of variable drainage levels. Before such models are applied, they should be thoroughly
tested and evaluated using country- or region-specific field data.

Choice of management data for organic soils
The same considerations apply as for management data for CM activities on mineral soils, as described in
Section 2.9.4.2 of this supplement.
Area data on land use and practices can be available according to either Reporting Method 1 or 2 as described in
Section 2.2 of this supplement. Management data required for each of the three tiers are outlined briefly below.

Tier 1
Drainage of organic soils results in immediate and ongoing emissions that are not restricted to a 20-year time
period, but are determined by subsidence rates, peat thickness, and technical possibilities of deepening thedrainage base in the subsiding land. Net carbon emissions and removals from the soil in the base year can beestablished based on data from only the base year. The types of land-use changes and management practices that
occur at Tier 1 are in principle the same as those for mineral soils.

Tier 2
It is good practice to disaggregate data on management practices by drainage depth, nutrient status of the organicsoil, land-use intensity, and organic soil type if appropriate emissions factors for on-site and off-site CO2
emissions and removals are available. In many instances, standard drainage depths are used in management
practices and disaggregation may not be useful for improving the accuracy of the emission and removal
estimates. Where significant variation in drainage depth exists for different management practices, and whereappropriate emission and removal factors exist, it is good practice to improve the accuracy of an inventory by,for example, separating out drainage classes. Tier 2 methods may require area descriptions of higher resolution
than those in Tier 1. Rigorous criteria should be applied to ensure that any change in emissions or removals isneither under- nor overestimated.

Tier 3
Management data used in the more sophisticated Tier 3 methodologies need to be consistent with the level ofdetail required by the model. It is good practice to use quantitative management data at a spatial resolution
appropriate for the model.

2.9.4.3

N ON -CO 2 GHG EMISSIONS FROM IN - SITU ABOVE - GROUNDWOODY BIOMASS BURNING

In-situ above-ground woody biomass burning is reported under CM. The decision tree in Figure 2.9.1 provides
general guidance for applying the appropriate tier level. Equation 2.27 in Chapter 2 and Section 5.2.4 in Chapter
5, Volume 4 of the 2006 IPCC Guidelines give guidance for estimating N2O and CH4 emissions from in-situ
above-ground woody biomass burning. If CM is a key category and in-situ above-ground woody biomassburning is significant, it is good practice that Parties use either Tier 2 or Tier 3 methods.

EMISSIONS FRO M LIMING AND UREA AP PLICATIONThe non-CO2 GHG emissions associated with soil management on land under CM as well as CO2 emissions
from liming and urea application are in most cases not reported under CM but under the Agriculture Sector.
163

According to paragraph 1 of Annex II to decision 2/CMP.8 estimates of emissions from sources and removals by sinks
from for Article 3.3 and 3.4 activities are to be clearly distinguished from anthropogenic emissions from the sources listed
in Annex A to the KP (FCCC/KP/CMP/2012/13/Add.1, p.18).

164

The reporting categories for the emissions will be considered by SBSTA at its 39th session. Any change to the decisions
about reporting of these emissions should also be reflected in the reporting under the KP LULUCF activities.

When reporting these emissions, it is good practice to ensure consistency, completeness and no double-counting
under Agriculture or CM (see Section 2.4.4.2 of this supplement).

2.9.4.5

T HE TRADE - OFFS AND SYNERGIES O F CM ON SOIL CARBONSTOCKS AND NON -CO 2 GASES

Some management practices adopted to increase soil carbon may also influence the emissions of non-CO2 gases.
Many of these effects are included in Chapters 5 and 11, Volume 4 of the 2006 IPCC Guidelines, but there may
be other effects on non-CO2 gases not considered. The effects on non-CO2 emissions of these and othermanagement practices may be included in higher tier methods for estimating CM emissions and removals.
Examples of how these effects could be estimated include: 1) direct measurement of the non-CO2 GHG atrepresentative sites and 2) estimation of emission rates based on literature values taking into accountmanagement, soil and climate. Box 2.9.4 gives examples of such potential trade-offs and synergies.
BOX 2.9.4
EXAMPLES OF POSSIBLE INFLUENCES OF REDUCED TILLAGE ON N2O EMISSION

Adoption of reduced tillage or NT often increases soil carbon in croplands. At the same time,
however, it may also alter N2O emissions, through effects on porosity (and the fraction of theporosity occupied by water; (Ball et al., 2008), nitrogen and carbon cycling (Six et al., 2004; Druryet al., 2006; Ahmad et al., 2009) temperature (Singurindy et al., 2009), and other factors (Lee etal., 2009). The observations are inconclusive, with some studies showing higher N2O emission
under NT than under tilled systems (Six et al., 2004; Liu et al., 2006; Ball et al., 2008; Rochette etal., 2008; Ahmad et al., 2009; Suddick et al., 2011), while others show little effect or lower N2Oemissions (Helgason et al., 2005; Venterea et al., 2005; Elder and Lal, 2008; Gregorich et al.,2008; Petersen et al., 2008; Bhatia et al., 2010; Chirinda et al., 2010). The available data suggestthat this variable response depends on interactive effects of soil and climate, and that more wet
environments with poorer aeration, in which N2O emissions generally tend to be highest, are also
associated with higher emissions under NT than under conventional tillage (Ball et al., 2008).

GRAZING LAND MANAGEMENT

2.10.1

Definitional issues and reporting requirements

Grazing Land Management (GM) is the system of practices on land used for livestock production aimed atmanipulating the amount and type of vegetation and livestock produced165. Lands under GM are predominantly
used for production of herbaceous perennial vegetation (introduced or indigenous) for harvest by grazing, cutting,or both.
Given the potential overlap with other activities, it is good practice for countries to specify what types of lands
are included under other activities under Article 3.3 and elected under Article 3.4. This will enhance thecomparability of reporting across countries and ensure there is no double-counting of GHG emissions andremovals.
Parties should aim for consistency and completeness across activities. For example, all lands that were Forest
Land on 31 December 1989 and that are subject to GM in the reporting year need to be identified, tracked andreported as a separate category under D (see Section 2.6 of this supplement).
Some lands included under GM may have trees or shrubs. In the first commitment period, some countries
included certain types of lands with woody biomass under GM, even if the cover met the thresholds for forest.
For consistency and to achieve transparency in reporting, it is good practice in the second commitment period
for those countries to ensure that double-counting with FM is avoided and to document how consistency isachieved with KP activities reported previously. Further guidance is provided in Section 1.2 of this supplement.
Permanent grasslands, pastures, rangelands or savannahs are normally included under GM if growing of forage
crops or grazing is the most important activity on the area (see Section 1.2 of this supplement). Protected lands,
such as those subject to permanent cover programmes, are also normally included under GM if they are also used
for livestock production. Treed areas on grassland or being grazed that were established after 1990 and meet thedefinition of a forest can qualify as AR, and if they do, are included under those categories (see Section 1.3 ofthis supplement). Recognizing that the forest definition is threshold based, in order to achieve consistency withestablished practice during the first commitment period, countries can continue to report by taking account ofpredominant land use, as reviewed under the provisions of the KP (Section 1.2 of this supplement).
Areas under CM that are only temporarily used for grazing, as part of a cropping rotation, would normally be
included under CM (see Section 2.9 of this supplement). If CM is not elected, such land can be included underGM, subject to national criteria that are consistently applied. If a country reports all cropland and grassland used
for livestock production under CM (or GM), then the Party does not need to differentiate between CM or GM
activities. If GM is elected with CM, it is good practice to include all cropland under CM and all grassland used
for livestock production under GM (see Chapter 1 of this supplement). The criteria used to distinguish between
land under CM and GM needs to be explicitly stated and applied consistently based on national definitions.
If GM is elected with RV (see Section 2.11 of this supplement), the criteria used to distinguish between land
under RV and GM needs to be explicitly stated and applied consistently based on national definitions. It is goodpractice to include revegetated land that is used predominantly for production of livestock under GM.
The aim of reporting is to identify and report trends in the carbon stocks resulting from GM over time. The
methodology for estimating CO2 emissions and removals is based on the premise that changes in carbon stocks
over time occur following changes in management that influence the rates of either carbon additions to, or
carbon losses from, soil. If management practices have not changed over a long period, the carbon stocks are
assumed to be at equilibrium, and hence the change in carbon stocks is deemed to be zero. Parties are encouraged
to use methods that show systematic changes in the carbon stocks rather than inter-annual variability and shortterm temporal dynamics. Another factor that may mask the carbon trend or signal is the occurrence of natural
disturbances on land under GM. Box 2.10.1 provides an example of practical application of elected GM.

GRAZING LAND MANAGEMENT – COUNTRY EXAMPLE

Denmark elected GM. The land included in GM is equal to the area of permanent grassland.
Grassland is defined as all land not meeting the definitions of Forest Land, Cropland, Wetlands, orSettlements and is identified using remote sensing. All grass in rotation with annual crops isincluded within Cropland. Grassland includes land identified as under permanent grazing plus anyother permanent grassland regardless of grazing. Denmark uses the same carbon stock change
estimation methods for Grassland for national inventory reporting as used for GM for reporting for
the KP. Grazing on Grassland is extensive and carbon stocks of mineral soils are estimated not tochange over time. Some carbon stock losses occur under grazing management as emissions fromorganic soils under Grassland remaining Grassland and residual C losses from Land converted to
Grassland in the past. The number of days of grazing within GM is also used in the estimates ofN2O emissions from nitrogen deposited from grazing animals. This ensures consistent reporting
between N2O emissions under Agriculture and CO2 emissions under GM for the KP.
To use the proposed methodology for determining carbon stock change, the total GM area needs to be
subdivided into areas of mineral and organic soils. The lands under GM are also subdivided under various sets ofmanagement practices (which may overlap both in time and space) for the base year and each of the years in thecommitment period, such as those provided in Table 6.2, Chapter 6, Volume 4 of the 2006 IPCC Guidelines. GM
practices that affect carbon stocks include animal stocking rate, fertility management, irrigation management,
species composition and fire management. The carbon stock change factors depend on both the current andprevious management. Some areas may be emitting CO2, others may be sequestering carbon, while others may
be in equilibrium and this may change if management changes. Further details can be found in Chapter 6,
Volume 4 of the 2006 IPCC Guidelines. See also Section 2.10.2 of this supplement.

2.10.2

Base year

Under Article 3.4 of the KP, emissions and removals resulting from GM are estimated using a net-net accounting
approach (as are all elective activities under Article 3.4). Net-net accounting requires that GHG emissions andremovals are estimated for the base year and each year of the commitment period166. This entails determining thetotal area under GM for the base year and for each year of the commitment period and calculating the carbon
stock change for those areas. Guidance for estimating the corresponding non-CO2 GHG emissions from GM arecovered in Chapters 10 and 11, Volume 4 of the 2006 IPCC Guidelines. Guidance on reporting those non-CO2
GHG emissions under Agriculture is identical to that provided in Section 2.9.4.4 and 2.4.4.2 of this supplement.
For most Parties with commitments under the KP, the base year is 1990. Under the provisions of Article 4.6 of
the UNFCCC and Article 3.5 of the KP, however, Parties with economies in transition (EITs) are granted someflexibility on the level of historical emissions chosen as a reference.
If the area under GM changes significantly between the base year and the commitment period, this may lead toestimates on the basis of moving land (that is, subtraction of stock changes on a land base that changes in size
over time; see Box 2.10.2). For GM, the guidance provided in the GPG-LULUCF (Box 4.2.8) acknowledges thatsome of the area of the activity in the ‘base year only’ may no longer be reported under that activity in thereporting year. Where this area is not transferred to another reported activity the associated emissions andremovals will be accounted as zero in that year. In order to achieve transparency in reporting, it is good practice
to describe the consequences of this exclusion on reported emissions and removals.

166

Net-net accounting refers to the provisions of paragraph 10 of the Annex to Decision 2/CMP.7 contained in document
FCCC/KP/CMP/2011/Add.1, p.14.

AN EXAMPLE OF GRAZING LAND MANAGEMENT AREAS IN BASE YEAR
AND IN THE COMMITMENT PERIOD (NET-NET ACCOUNTING)

In this example the area under GM in the base year expands to a larger area in the reporting year
during the commitment period. Some of the area was under GM in both the base year and during
the reporting period (a). Some of the area under GM in the base year is no longer under GM in thereporting year (b). There are also areas under GM in the reporting year that were not under GM in
the base year (c). Area (D) is under GM, but was subject to Deforestation (D) which takes
precedence. Area (e) has been converted to cropland, but remains under FM under the CEFC
provision. Under the KP, the emissions and removals in areas (a) + (b) in the base year arecompared to emissions and removals in areas (a) + (c) – (D) –(e) in the reporting year.

Historical data on land use and management practices in 1990 (or the appropriate year(s)) and in years prior to1990 are needed to establish the 1990 base year net emissions and removals of soil carbon from GM. The Tier 1
method described in Section 6.3.3, Chapter 6, Volume 4 of the 2006 IPCC Guidelines for mineral soils assumes
that a change in land use or management has an impact on carbon emissions and removals for a duration of 20
years; hence, in this approach and if a change in management has taken place since 1970, the net carbon stockchange in 1990 has to be calculated taking this change into account. If area and activity data are available for1970 to 1990, the net carbon stock change during the 1990 base year can be established using the default carbon
emission and removal factors. For organic soils, the inventory time period is treated the same as long-termdrained organic soils, with Tier 1 emission factors provided in Chapter 2 of the Wetlands Supplement (seeFootnote 1, Section 2.1 of this supplement).
The duration of impact of management practice on soil organic carbon may be different from the default periodof 20 years used to reach a new equilibrium. If data on the duration of impact are available, it is good practice to
use the appropriate time period, based on country-specific data and measurements (see Tier 2 and Tier 3
approaches in Section 2.10.4 of this supplement).
If area and activity data are not available for 1970 to 1990, countries can establish the base-year 1990 carbon
stock change using the most appropriate time series to estimate the 1990 value, in a manner consistent withguidance provided in Section 5.3.1, Chapter 5, Volume 1, of the 2006 IPCC Guidelines. It is good practice to use
a time period equivalent to 20 years that includes 1990 or as close to 1990 as possible.
The results of accounting on a net-net basis depend not just on changes in land management practices, but also
partly on when the base year and commitment period years fall within the temporal dynamics of carbon

sequestration processes. As noted above, carbon stock change resulting from land-use and management changes
on mineral soil tend to persist for about 20 years, after which the carbon levels of land under GM approaches a
new equilibrium carbon stock. The rate of carbon sequestration in land under GM following a change inmanagement in which carbon additions increase or carbon losses decline tends to be high in the first decades andthen declines over time, as illustrated in Figure 2.9.2 of this supplement. This will be reflected in net sinks andsources in the accounting.

2.10.3

Choice of methods for identifying lands subjected toGrazing Land Management

General guidance on consistent representation of lands is provided in Chapter 4 of the 2006 IPCC Guidelines
with additional guidance about identification of lands subject to GM provided in Sections 1.1, 1.2, 2.1, and 2.2 ofthis supplement.
According to Decision 2/CMP.8167, the geographical location of the boundaries of the area that encompass land
subject to GM needs to be reported annually, along with the total land areas subject to this activity. The
geographical location of boundaries may include a spatially explicit specification of land subject to GM, but does
not have to. Instead, the boundaries of larger areas encompassing smaller lands subject to GM may be provided,
along with estimates of the area subject to GM in each of the larger areas. In either case, the land subject to GM
and the management thereon need to be tracked through time because the continuity and duration of management
practices and changes affects carbon emissions and removals.
It is good practice to follow continuously the management of land subject to GM. The tracking can be achievedby continuously tracking land subject to GM from 1990 until the end of the commitment period (see Section
2.10.1). Alternatively, countries could develop statistical sampling techniques, consistent with the advice inAnnex 3A.3, Chapter 3, Volume 4 of the 2006 IPCC Guidelines, which allow the transitions of management
practice on GM land to be determined (see also Section 2.4.1 of this supplement).
At the national level, it is good practice, when developing a sampling strategy, to identify criteria that could be
used to set up a stratified sampling scheme. Stratification criteria may include relatively static biophysicalcharacteristics, such as climate and soil type, as well as management practices and natural disturbances which
tend to be more dynamic drivers of change in emissions and removals from carbon pools.
Management factors and disturbance information that may be useful in establishing a national stratification
scheme include:

Level of input of biomass or grassland productivity, manure, and other organic amendmentsGrazing intensity (stocking rate, frequency, seasonality)

Prescribed fireRe-seeding



Irrigation management

DrainageInclusions of woody biomass (e.g. shrubland, shelterbelts, other perennial plantations on grazed lands)

For all resulting subcategories under GM, the area derived from conversion of forests (i.e. D) since 1990 need to
be tracked separately, as these will be reported as units of lands subject to D (See Section 2.6 of this supplement).
Emissions and removals resulting from conversion of FM to GM due to the harvest and conversion of forest
plantations to non-forest land could be reported under CEFC according to Decision 2/CMP.8168.
At higher tiers, further subdividing of the area subject to GM may be necessary. Methods to identify lands
subject to GM with necessary disaggregation available in some Annex I countries include the following:

National land use and management statistics: the agricultural land base including land subject to GM issurveyed in most countries on a regular basis. These may be derived, in part, from remote sensing ofpasture/rangeland and soil surface condition and changes in stocking rate.

Inventory data from a statistically based, plot-sampling system: land use and management activities aremonitored at specific permanent sample plots that are revisited on a regular basis.

Chapter 2: Methods for estimation, measurement, monitoring and reporting

Information on these areas either needs to be compiled for all lands subject to GM or summarised as estimates
for all the strata (defined by the boundaries of the areas of GM) that a Party chooses to apply for the reporting of
its land use statistics. Further good practice guidance on identifying land areas is provided in Section 2.2 of this
supplement.

2.10.4

Choice of methods for estimating carbon stockchanges and non-CO 2 GHG emissions

It is good practice to report GM following the 2006 IPCC Guidelines methodologies for grassland estimates of:

Annual changes in carbon stocks of above- and below-ground biomass;

Annual changes of dead organic matter (dead wood and litter; DOM);Annual changes in organic carbon stocks in mineral soils and emissions and removals in organic soils;

Annual emissions of non-CO2 gases from woody biomass burning.

Section 2.3.6 of this supplement provides guidance about the choice of methods and identifying whether GM is a
key category. If GM is a key category, the inventory compiler can determine if certain subcategories, such as
mineral soil or above-ground biomass, are significant. Section 1.3.3, Chapter 1, Volume 4 of the 2006 IPCC
Guidelines suggests ranking subcategories according to their contribution to the aggregate key category. It may
be appropriate to focus efforts towards methodological improvements of the significant subcategories (seeSection 2.3.6 of this supplement).
Decision 2/CMP.7169 specifies that a Party may choose not to account for a particular pool in a commitment
period, if transparent and verifiable information is provided that demonstrates that the pool is not a source.
Requirements for reporting excluded pools and documenting that a pool is not a source can be found in Section
2.3.1 of this supplement. It is possible that Parties will use different tiers to prepare estimates for individual
subcategories (e.g. changes in organic carbon stocks in mineral soils and emissions and removals in organicsoils). Since different methods may yield different estimates, each with different levels of uncertainty, it is goodpractice to use the same tier and methodology for estimating carbon emissions and removals from eachsubcategory and pool for the full time series, for example, in 1990 and during the commitment period.
Methods for estimating GM carbon emissions and removals for the base year and the commitment period areprovided in Chapter 2 and Chapter 6, Volume 4 of the 2006 IPCC Guidelines. The following sections of this
supplement highlight aspects of these methods specific to the KP.

2.10.4.1

B IOMASS AND DEAD ORGA NIC MATTER

Without changes in management practices, herbaceous grassland vegetation is assumed to cycle annually suchthat biomass gains equal biomass losses in a single year. For perennial woody biomass, carbon stock changes inbiomass and DOM pools should be estimated unless the Party to the KP chooses not to report on a certain pooland provides verifiable information that carbon stocks are not decreasing.
For carbon stock changes in biomass resulting from changes in GM, it is good practice for Parties to use thedecision tree in Figure 2.10.1 to identify the appropriate tier to estimate carbon stock changes in biomass andDOM under the KP. Relevant methods for estimating carbon stock changes in above- and below-ground biomass,and DOM can be found in Sections 6.2.1 and 6.2.2, Chapter 6, Volume 4 of the 2006 IPCC Guidelines,
respectively. Default coefficients for above-ground woody biomass and harvest cycles in agroforestry or
silvopastoral systems containing perennial species are provided in Table 6.1, Chapter 6, Volume 4 of the 2006
IPCC Guidelines.

2.10.4.2

S OIL CARBON

In most grasslands, the main carbon emissions and removals associated with changes in land use andmanagement for GM activities is from changes in organic carbon in soil. The 2006 IPCC Guidelines identifies
two sources or sinks of CO2 from agricultural soils:Net changes in soil organic carbon associated with changes in land use and management on mineral soil

Total annual emissions and removals of CO2 are calculated by summing emissions and removals from the two
subcategories (mineral and organic soils) using methods outlined in Chapter 6 and Equation 2.24 of Chapter 2,
Volume 4 of the 2006 IPCC Guidelines and updated in the Wetlands Supplement (see footnote 1, Section 2.1 ofthis supplement).

MINERAL SOILS
Methods for estimating mineral soil carbon stock changes resulting from changes in GM fall under one of threemethodological tiers described in Sections 1.3.2 and 1.3.3, Chapter 1, Volume 4 of the 2006 IPCC Guidelines.

Methods for estimating carbon stock changes in mineral soils
The decision tree in Figure 2.10.1 should be used to decide which tier to use for estimating carbon stock changes
associated with changes in GM practices under the KP. It is good practice to use Tier 2 or Tier 3 methods if
mineral soils are a significant subcategory under GM. It is good practice to follow continuously the GM
practices from the base year through the commitment period as described in Section 2.10.3 of this supplement.
For discussion of how to estimate the GM area, see Section 1.3 of this supplement.

Tier 1The Tier 1 method for estimating carbon stock changes in mineral soils is described in Section 2.3.3.1, Chapter 2,
Volume 4 and Section 6.2.3, Chapter 6 in Volume 4 of the 2006 IPCC Guidelines. This guidance assumes a new
equilibrium soil organic carbon stock is achieved after 20 years in a practice.
Section 6.2.3.4, Chapter 6 and Chapter 2 in Volume 4 of 2006 IPCC Guidelines outlines the steps for estimating
average annualized rates of organic carbon stock change in mineral soils of grasslands using the default reference
carbon stocks (Table 2.3), carbon stock change factors (Table 6.2) and Equation 2.25. The Tier 1 method can beused to estimate carbon emissions and removals resulting from changes in management practices across a rangeof temperature and moisture regimes and soil types. Box 2.9.3 provides an illustration of how to apply Tier 1 toestimate carbon stock changes for CM practices that are not continuous over time, which is also applicable for
GM.

Chapter 2: Methods for estimation, measurement, monitoring and reporting

Tier 2The Tier 2 method also uses the methodology described in Chapter 6, Volume 4 of the 2006 IPCC Guidelines,
but now the default relative carbon stock change factors are replaced with region- or country-specific values. It isgood practice to obtain region- or country-specific emissions factors from literature values, long-term
experiments or the local application of well-calibrated, well-documented soil carbon models. Region-specificdata for soil carbon content (such as that available from national soil inventories) can also be used.
To ensure that region-specific carbon stock change factors better represent actual emissions and removals in agiven region than default relative carbon stock change factors, rigorous criteria demonstrating that the more
specific factors do not lead to under- or overestimation of the soil carbon stock change should be applied.
Region- or country-specific factors should be based on verified soil carbon model estimates or measurementsthat are, in addition to being documented in accessible publications, conducted frequently enough, over a longenough time period and with sufficient spatial density to reflect variability of the underlying biochemical
processes.
For Tier 2 approaches, it is good practice to replace the 20-year default with a value that reflects national orregional information about the duration of GM practices to reach a new equilibrium in soil carbon stocks.
Rigorous criteria should be applied in order to ensure that any carbon stock change is neither under- noroverestimated. It is good practice that stock change factors be based on experiments sampled according to theprinciples set out in Section 2.3.3, Chapter 2, Volume 4 of 2006 IPCC Guidelines, and to use experimental
values if they are more appropriate than the default values for region and management practice. Factors based onmodels should only be used after the model has been tested against experiments such as those described above
and any model should be widely evaluated, well-documented and archived. It is good practice to provide
confidence limits or uncertainty estimates associated with regional, country-specific or local stock change factors.

Tier 3Tier 3 methods generally encompass a range of methodologies more elaborate than Tier 2. Tier 3 methods areusually based on sophisticated modeling techniques, and are often linked to geographical databases. Comparedwith the static matrix used at Tiers 1 and 2, Tier 3 can represent the management history of a land that facilitates
calculation of soil carbon changes resulting from multiple changes in management practices over time including
rotational changes in land use. Like Tier 2 methods, Tier 3 methods can also take into account a longer time
period sufficient to reach equilibrium (i.e. longer than 20 years). Current computing power makes it possible tolink spatially disaggregated (stratified) land data to management practice data. The analytical system canestimate carbon stock changes over time by linking equations describing the rate of change in soil carbon under
specific management practices with carbon contents, initialised by existing data and cross-checked periodically.
Tier 3 methods can also be based on repeated statistical sampling consistent with the principles set out in Annex
3A.3, Chapter 3, Volume 4 of the 2006 IPCC Guidelines. The sampling protocol should be of sufficient density
to capture the soil types, climatic regions and management practices.

Choice of carbon stock change factors for mineral soils
Tier 1
At Tier 1, average annualized carbon stock changes in mineral soils are calculated from default values bydividing the 20-year stock change by 20, as set out in Equation 2.25, Chapter 2, Volume 4 of the 2006 IPCC
Guidelines. Default reference (under native vegetation) soil organic C stocks (SOCREF) for mineral soils and fulldetails of default relative stock change factors for land use (FLU), input (FI) and management (FMG) factors (over20 years) can be found in Table 2.3 (for SOCREF) and Table 6.2 (for FLU, FI and FMG) in Chapters 2 and 6,
respectively, of Volume 4 of the 2006 IPCC Guidelines. Management practice is assumed to influence stocks toa depth of 30 cm. For a summary of the steps, see Section 2.3.3, Chapter 2 in Volume 4 of the 2006 IPCC
Guidelines.

Tier 2
At Tier 2, some or all of the default values for carbon stock change (Tier 1) are replaced by values shown to be
more specific to account for national or regional soil carbon stock changes. These new values may be based onliterature values, measured changes in carbon stocks, carbon models, or a combination of these sources. (See
‘Choice of management data for mineral soils’ below for examples). It is good practice to derive relative stockchange factor values for a higher resolution classification of management, climate and soil types if there are
significant differences in the stock change factors among more disaggregated categories based on an empiricalanalysis. Reference soil organic carbon stocks (SOCREF) can also be derived from country-specific data in a Tier
2 approach. Additional guidance is provided in Section 2.3.3.1, Chapter 2, Volume 4 of the 2006 IPCC
Guidelines.

2.156

2013 Revised Supplementary Methods and Good Practice Guidance Arising from the Kyoto Protocol

Chapter 2: Methods for estimation, measurement, monitoring and reporting

Tier 3For mineral soils, Tier 3 approaches may use dynamic models and or detailed soil carbon inventory
measurements as the basis for estimating annual stock changes. Tier 3 methods may involve the use of countryderived carbon stock change factors which may be calculated using sophisticated models. The carbon models
used for Tier 3 are generally more complex than those in Tier 2, taking into account soil (e.g. clay content,chemical composition, parent material), climate (e.g. precipitation, temperature, evapotranspiration), andmanagement factors (e.g. species introduction or removal, carbon inputs, fertility amendments, vegetation
utilization by grazing livestock). Good practice requires that the models be calibrated using measurements atbenchmark sites, and that models and assumptions used are described transparently.
In all cases, rigorous criteria should be applied so that any change in carbon stocks is neither under- noroverestimated; models used to estimate carbon stock changes should be well-documented and should be
evaluated using reliable experimental data for conditions and practices to which the models are applied. It isgood practice to provide confidence limits or uncertainty estimates according to the descriptions in Sections
6.2.3.5 and 6.3.3.5, Chapter 6, Volume 4 of the 2006 IPCC Guidelines. Default carbon stock change factors may
also be replaced by values generated as part of national or regional carbon accounting systems (see Section
2.10.3 of this supplement).

Choice of management data for mineral soils
Area data on land use and practices can be available according to either Reporting Method 1 or 2 as described in
Section 2.2 of this supplement. Management data required for each of the three tiers are outlined briefly below.

Tier 1
Following Volume 4 of the 2006 IPCC Guidelines, impacts of land management change are assumed, by default,
to have an impact for 20 years. If area and activity data are available for 20 years prior to the base year, a net
carbon emissions and removals for the base year can be established using the default carbon stock change factors
described above. The changes in management practices at Tier 1 are the same as those given in the 2006 IPCC
Guidelines: differing degradation states, improved vs. unimproved grassland, and differing input levels for
improved grassland. Within these specific management changes, activities are defined semi-quantitatively, e.g.
non-, moderately-, and severely-degraded. Areas may be obtained from international data sets (e.g. FAO, World
Census of Agriculture, FAOSTAT), though some of these sources lack the spatial explicitness needed forreporting and may only be helpful for cross-checking data. If area and activity data are available for 1970 and
1990, a 1990 baseline net carbon stock change can be established using the default carbon stock change factors
described above and the area and activity data for 1970 and 1990.
If area and activity data are not available for 1970 to 1990, countries can establish the 1990 carbon stock changeusing the most appropriate time series to estimate the 1990 value, in a manner consistent with guidance provided
in Section 5.3, Chapter 5, Volume 1 of the 2006 IPCC Guidelines. It is good practice to use a time period
equivalent to 20 years that includes 1990 or as close to 1990 as possible.

Tier 2Tier 2 approaches are likely to involve a more detailed stratification of management systems than in Tier 1 if
sufficient data are available. These can include further subdivisions of GM categories (e.g. nature of degradation,
improved grassland subdivided by vegetation community). It is good practice to further subdivide default classes
based on empirical data that demonstrates significant differences in soil organic carbon storage among the
proposed categories. In addition, Tier 2 approaches can involve a finer stratification of climate regions and soil
types. Tier 2 methods may require area descriptions of higher resolution than those in Tier 1. An alternative tothe use of more detailed descriptor categories is the use of relationships relating the intensity of a practice (e.g.
grazing level) with a change in the carbon emission or removal factor. Alternatively, well-calibrated and wellevaluated models of soil carbon change, e.g. RothC (Coleman and Jenkinson, 1996; Shirato et al., 2004) can beused to generate either default carbon stock change factors or to generate the intensity relationships for eachactivity for different soils in different climatic regions. These examples show how, at Tier 2, activities can bemade more country-specific, but other refinements are also possible. In any case, rigorous criteria should beapplied so that emissions in the base year and removals in the inventory year are neither under- noroverestimated.

Tier 3
Management data used in the more sophisticated Tier 3 approaches are likely to be subdivided as described forTier 2 above. For application of dynamic models e.g. CENTURY (Parton et al., 1987), RothC (Coleman andJenkinson, 1996; Shirato et al., 2004), measured/estimated activity data based on national statistics (e.g. herbage
yield, input level of organic amendment), and detailed data of the combination of climate, soil and management
are needed.

ORGANIC SOILS
It is good practice to use the decision tree in Figure 2.10.1 to decide which tier to use for reporting carbon stockchanges in organic soils under the KP.

Methods for estimating CO 2 emissions and removals from organic soils
When organic soils are converted to or managed for agriculture, they are typically drained, tilled and fertilised,resulting in on-site CO2 emissions to the atmosphere as well as waterborne carbon losses that lead to off-site CO2
emissions. Countries may use methods of different tier levels for on-site and off-site CO2 emissions from organicsoils. The rate of CO2 release will depend on, inter alia, climate, the degree of drainage, nutrient status andpractices such as fertilisation and liming. Oxidation of organic material results in land subsidence and CO2
emissions will continue until the organic soil layer is depleted or until further lowering of the drainage base is nolonger feasible. Drained organic soils under GM can be rewetted while remaining under GM. Guidance on
rewetting and drainage of organic soils can be found in Section 2.12 of this supplement. The Wetlands
Supplement contains updated and new methodological guidance for estimating GHG emissions and removals
from drained and rewetted organic soils, (see Footnote 1, Section 2.1 of this supplement).

Tier 1The Tier 1 method for estimating emission and removals in organic soils is described in Sections 2.3.3 and6.2.3.2, Chapters 2 and 6, Volume 4 of the 2006 IPCC Guidelines, which include guidance for on-site CO2(including peat fires), off-site CO2 and CH4 from drained organic soils and drainage ditches (see Footnote 1,
Section 2.1 of this supplement).

Tier 2
If country- or region-specific data is available on CO2 emissions from organic soils, it is good practice to use
these instead of Tier 1 defaults if organic soils are a significant subcategory under GM. Any data used should beshown to be more reliable and representative for the national conditions than defaults. It is good practice to use afiner classification for climate and management practices, such as drainage classes, if there are significant
differences in measured carbon loss rates among the proposed classes.

Tier 3
A Tier 3 approach may involve estimation of CO2 and non-CO2 GHG emissions in an integrated way. However,double-counting and omissions in relation to reporting under Agriculture (see section 2.4.4.2 of this supplement)
need to be avoided.

Choice of carbon emission and removal factors for o rganic soils
Tier 1The Tier 1 default emission and removal factors are provided in Table 6.3, Volume 4 Chapter 6 of the 2006
IPCC Guidelines updated for on-site CO2 (including peat fires), off-site CO2 and CH4 from drained organic soils
and drainage ditches (see Footnote 1, Section 2.1 of this supplement).

Tier 2For organic soils, it is good practice to replace the default values with country- or region-specific factors. It isgood practice to use country- or region-specific emission and removal factors derived from measurements orexperiments within the region that are well-designed and employ adequate sampling and coverage. It is goodpractice to provide confidence limits or uncertainty estimates associated with any country- or region-specificemission and removal factors.

Tier 3For organic soils, CO2 emissions and removals may be estimated using a model or measurement based approach.
Time-dependent emission and removal factors capture more accurately the effects of land-use and managementchanges. Dynamic models could capture the influence of (changes in) land use and management practices,
particularly the effect of variable drainage levels. Before such models are applied, they should be thoroughly
tested and evaluated using country- or region-specific field data.

Choice of management data for organic soils
The same considerations apply as for management data for GM activities on mineral soils, as described earlier in
Section 2.10.3 of this supplement.
Area data on land use and practices can be available according to either Reporting Method 1 or 2 as described in
Section 2.2 of this supplement. Management data required for each of the three tiers are outlined briefly below.

2.158

2013 Revised Supplementary Methods and Good Practice Guidance Arising from the Kyoto Protocol

Chapter 2: Methods for estimation, measurement, monitoring and reporting

Tier 1
Drainage of organic soils results in immediate and ongoing emissions that are not restricted to a 20 year time
period, but are determined by subsidence rates, thickness of the peat and technical possibilities of deepening of
the drainage base in subsiding land. Net carbon emissions and removals from the soil in the base year can beestablished based on data from the base year only. The land-use changes and management practices at Tier 1 are
the same as those for mineral soils.
If rewetting of organic soils for GM occurs additional guidance for those lands is found in Chapter 3 of the
Wetlands Supplement (see Footnote 1, Section 2.1 of this supplement).

Tier 2
It is good practice to disaggregate data on management practices by drainage depth, nutrient status of the organicsoil, land-use intensity, and organic soil type if appropriate factors for on-site and off-site CO2 emissions andremovals are available. In many instances standard drainage depths are used in management practices anddisaggregation is not useful in improving accuracy of the emission and removal estimates. Where significant
variation in drainage depth exists for different management practices, and where appropriate emission andremoval factors exist, it is good practice to improve the accuracy of an inventory by, for example, separating out
drainage classes. Tier 2 methods may require area descriptions of higher resolution than those in Tier 1. Rigorous
criteria should be applied so that any change in emissions or removals is neither under- nor overestimated.

Tier 3
Management data used in the more complex Tier 3 methodologies need to be consistent with the level of detailrequired by the model. It is good practice to use quantitative management data at a spatial resolution appropriate
for the model.

and CH4 emissions from in-situ above-ground woody biomass burning. If GM is a key category and in-situ
above-ground woody biomass burning is significant, it is good practice to use either Tier 2 or Tier 3 methods.

associated with burning of savannas as well as CO2 emissions from liming and urea application are in most cases
not reported under GM but under the Agriculture Sector. When reporting these emissions, it is good practice toensure consistency, completeness and no double-counting under Agriculture and GM (see Section 2.4.4.2 of this
supplement).

170

According to paragraph 1 of Annex II to Decision 2/CMP.8 estimates of emissions from sources and removals by sinks
from for Article 3.3 and 3.4 activities are to be clearly distinguished from anthropogenic emissions from the sources listed
in Annex A to the KP (FCCC/KP/CMP/2012/13/Add.1, p.18).

The reporting categories for the emissions will be considered by SBSTA at its 39th session. Any change to the decisions
about reporting of these emissions should also be reflected in the reporting under the KP LULUCF activities.

REVEGETATION

2.11.1

Definitional issues and reporting requirements

Revegetation (RV) is a direct human-induced activity to increase carbon stocks on sites through theestablishment of vegetation that covers a minimum area of 0.05 hectares and does not meet the definitions ofAR172 (see also Footnote 1, Chapter 1 of this supplement).
Land should be classified as RV if it meets the RV definition and the activity takes place since 1 January 1990. RV
typically affects the above-ground carbon pool significantly and may also have a significant impact on belowground carbon pools through increases in soil carbon stocks.
RV implies that vegetation is established to replace the previous (sometimes minimal) ground cover that had
followed a land disturbance. For example, activities such as reclaiming or restoring herbaceous ecosystems on
degraded or carbon-depleted soils, establishment of vegetation cover on disturbed construction sites or minedlands, planting of trees, shrubs, grasses or other non-woody vegetation on various types of lands, including urban
areas, might qualify as RV (see Box 2.11.1). Any tree planting could be elected as a RV activity, if besides
meeting the area requirement for this activity it does not meet the requirements for a forest173, or satisfies thecriteria a Party uses to specify the shape of forests and areas subject to AR, D, or conversion of a natural forest toa planted forest (see Section 2.2.6.1 of this supplement). For example, in contrast to AR, RV does not necessarily
entail a change in land use. RV activities must be clearly separated from natural, non-human driven revegetation
processes.
Set-aside lands such as cultivated lands subjected to RV may be included under CM, if they are only temporarily
set-aside (typically this is for 5 years or less, but any set-aside land likely to return to Cropland under the national
conditions for set-aside land should be counted as Cropland).
It is good practice for Parties electing RV to provide documentation (a) describing how the included areas meetthe definition of RV and (b) how they can be distinguished from other activities under Articles 3.3 and 3.4.
The following general guidance is provided in order to ensure a reasonably transparent, consistent, complete andaccurate reporting of RV activities:

It is good practice to stratify lands subject to RV by either land-use category or land-use change type, by
type of RV activity, and final land use if different from the initial one.



It is good practice to further disaggregate each land-use category to be revegetated into subcategories
characterised by available information on climate, soil etc., whatever is most relevant for stratifying land
according to the effects of the activity on carbon stocks and carbon stock changes. This characterisation
would aid selecting suitable RV options and activity tracking; i.e. species, planting design, and soil
preparation.

Lands subjected to RV and each of its subcategories (if any) must be clearly identified as to their individual
locations and areas (see Section 2.11.3 in this supplement).

Further guidance is provided in Section 1.2 in this supplement.

Choice of methods for identifying lands

Land areas subject to RV can be represented with data obtained with either Approach 2, provided there isadditional spatial information, or Approach 3 (see Section 3.3.1, Chapter 3 in Volume 4 of the 2006 IPCC
Guidelines). It is good practice that the chosen Approach be consistent with the one used for identifying andtracking the lands of other KP activities, be they mandatory (Article 3.3) or elected (Article 3.4).
Generally, all lands subject to RV since 1 January 1990 should be tracked in agreement with the national criteriathat establish a hierarchy among Article 3.4 activities (if applicable) as explained in Section 1.2 of this
supplement.
The geographical location of boundaries may include a spatially explicit specification of each land subject to RV,
but does not have to. Instead, the boundaries of larger areas encompassing smaller lands subject to RV may beprovided, along with estimates of the areas subject to RV in each of the larger areas. In either case, the lands
subject to RV and the management thereon need to be tracked continuously through time. Continuity inmonitoring and reporting of management of revegetated land could be achieved either by continuously tracking
each land subject to RV from 1990 until the end of the commitment period (see Section 2.9.2 for CM and
Section 2.10.2 for GM of this supplement or Section 3.3, Chapter 3 in Volume 4 of the 2006 IPCC Guidelines
for land-use categories in general) or by developing statistical sampling techniques (see Annex 3A.3, Chapter 3
in Volume 4 of the 2006 IPCC Guidelines) that allow the transition of different types of management on RV land
to be determined.
Methods for monitoring RV lands depend on the kind of land use at the start and end of a RV activity. A
common criterion, the minimum area of 0.05 hectares, has to be applied and all carbon pools have to beconsidered unless they are demonstrated not to be a source. If RV were done with herbs or grasses, monitoringshould use methods appropriate for monitoring GM (see Section 2.10 of this supplement). If RV were done withtree species, monitoring methods should be the same as those used for monitoring AR activities (see Section 2.5of this supplement) or FM activities (see Section 2.7 of this supplement). For designing RV activities on
settlement lands, it is good practice to use tree inventories (if available), land surveys on parks and green spaces,brownfields and any other spatial information on areas amenable to revegetation. A clear definitional distinction
with respect to AR is required.

RV activity are described in Chapters 4 – 9, Volume 4 of the 2006 IPCC Guidelines. The biomass carbon pool islikely to be the carbon pool most affected by RV. Parties are encouraged to use higher tier methods for reporting

Chapter 2: Methods for estimation, measurement, monitoring and reporting

carbon stock changes in biomass. It is good practice to use Tier 2 or Tier 3 methods for estimating carbon stockchanges from biomass if RV is a key category.
Relevant methods and approaches for estimating carbon stock changes in mineral soils and carbon emissions andremovals from organic soils on RV lands can be found in Chapters 4 - 9 and 11, Volume 4 of the 2006 IPCC
Guidelines. For urban soils, methods are described in Chapter 8, Volume 4 of the 2006 IPCC Guidelines.
In the case of a RV activity on Cropland or Grassland, guidance on choice of methods (Tier 1) for stock changes
in mineral soils can be found in Sections 2.9.4.2 and 2.10.4.2 of this supplement. It is good practice to use Tier 2
or Tier 3 for estimating carbon stock changes from mineral soils if RV is a key category. The decision tree forselecting the tier for estimating carbon stock changes in mineral soils under RV is analogous to that for CM (seeFigure 2.9.1 of this supplement). At higher tiers, carbon stock change factors can be obtained from relevant
literature (e.g. Akala and Lal, 2000), long-term experiments and models. Further guidance on the use of higher
tier models can be found in Section 2.3.3, Chapter 2, Volume 4 of the 2006 IPCC Guidelines.
The decision tree for methods to estimate emissions from organic soils under RV is similar to the one drawn for
CM (see Figure 2.9.1 of this supplement) if the RV activity occurs on Cropland or Grassland. The methods
described under Tiers 1, 2 and 3 for either FM, CM or GM also apply to RV activities involving either treed
lands, croplands or grasslands (see Sections 2.7, 2.9 and 2.10, respectively, of this supplement) and Chapters 4 9 in Volume 4 of 2006 IPCC Guidelines).
CO2 emissions from liming are reported under Agriculture.

2.11.4.1

C HOICE OF CARBON STOCK CHANGE FACTORSTIER 1
Estimation of RV is more dependent on national definitions than is the case for other Article 3.4 activities. Whenusing Tier 1 methodologies, it is good practice to provide national information that substantiates that theyadequately represent a Party’s national circumstances (Sections 2.2 and 2.3 of this supplement and Chapters 4 –9, Volume 4 of the 2006 IPCC Guidelines contain methodologies that may be relevant). It is good practice for a
Party electing RV to provide values for stock changes in each carbon pool. If RV is deemed a key category, thenit is good practice to use Tier 2 or 3 methods. Decision 2/CMP.7174 specifies that a Party may choose not toaccount for a particular pool in a commitment period, if transparent and verifiable information is provided that
demonstrates that the pool is not a source. Requirements for reporting excluded pools and documenting that apool is not a source can be found in Section 2.3.1 of this supplement.

TIER 2
At Tier 2, it is good practice to provide verifiable methods and documentation to show how the carbon stockchange has been estimated for each pool elected under a RV activity. For any carbon pool not reported, it is goodpractice to provide verifiable information to demonstrate that it is not a source of anthropogenic GHG emissions.

TIER 3
At Tier 3, ecosystem carbon cycle models parameterised for the relevant plant functional types and soils includedin the selected RV area could be used to estimate annual carbon emissions and removals. These models need tobe calibrated and validated against field observations that represent the national circumstances, be fully
documented and archived.

2.11.4.2

C HOICE OF MANAGEMENT DATA

Activities such as reclaiming or restoring herbaceous ecosystems on carbon-depleted soils, environmental
plantings, planting of trees, shrubs, grasses or other non-woody vegetation on various types of lands, including
urban areas, which qualify as RV can be considered. Area data on land uses and practices need to be available inaccordance with Approach 2 or Approach 3, following guidance given in Section 2.2.4 of this supplement.
Management data on RV required for each of three tiers are outlined briefly here.

TIER 1
Following guidance in Volume 4 of the 2006 IPCC Guidelines, impacts of land-use change or land managementchange under a RV activity are assumed, by default, to fully develop at the end of 20 years. The choice of default
emission factors influenced by management factors depends on the particular land uses involved in a particular

RV activity. At a minimum, the six broad land-use categories and changes between these categories need to be
specified and different types of RV activities considered separately.

TIER 2
For Tier 2, some management practices for RV may be either subdivided or new ones may be added to makethem country-specific, depending on the land uses involved in a RV activity. It is good practice that thosesubdivisions reflect close relationships between management practices and changes in carbon pools.

TIER 3
Management data used in the more complex Tier 3 methodologies need to be consistent with the level of detailrequired by the model or models used to describe a particular RV activity. It is good practice to use management
data at a spatial resolution appropriate for the model, and to have, or be able to estimate reliably, quantitative
measures of the management factors required by the model.
It is good practice to provide detailed documentation specifying the practices included under RV and the carbon
emission and removal factors associated with each practice for each pool elected.

2.11.4.3

N ON -CO 2 GREENHOUSE GASESThe choice of methods for estimating N2O and CH4 emissions from a RV activity depend on the land-use
categories involved (e.g. Cropland, Grassland, etc.) and the particular management practices (e.g. biomassburning, nitrogen fertilisation, liming, etc.) on those lands.
Methodologies for estimating N2O and CH4 emissions from RV activities involving the management of trees(outside forests but not in settlements), croplands or grasslands can be found in Sections 2.7.3 (FM), 2.9.4 (CM)or 2.10.4 (GM), respectively, of this supplement. For RV activities leading to the establishment of wetlands,
appropriate methodologies can be found in the Wetlands Supplement (see Footnote 1, Section 2.1 of this
supplement. N2O and CH4 emissions from the RV on Settlements can be estimated with methods described in
Chapter 8, Volume 4 of the 2006 IPCC Guidelines. When reporting N2O and CH4 emissions from RV, it is goodpractice to ensure consistency, completeness and no double-counting under Agriculture or CM (see Section
2.4.4.2 of this supplement).

WETLAND DRAINAGE AND REWETTING

2.12.1

Definitional issues and reporting requirements

According to Decision 2/CMP.7“Wetland Drainage and Rewetting” is a system of practices for draining andrewetting on land with organic soil that covers a minimum area of 1 hectare. The activity applies to all lands
that have been drained since 1990 and to all lands that have been rewetted since 1990 and that are notaccounted for under any other activity, where drainage is the direct human-induced lowering of the soil watertable and rewetting is the direct human-induced partial or total reversal of drainage175
Wetland Drainage and Rewetting (WDR) can only be implemented on organic soils, but under any land-use
category. Organic soils are defined in Annex 3A.5, Chapter 3, Volume 4 of the 2006 IPCC Guidelines. The
definition of the 2006 IPCC Guidelines largely follows the FAO (1998, 2006) definition of ‘Histosol’, but allows
for country-specific definitions (Chapter 1 of the Wetlands Supplement [see Footnote 1, Section 2.1 of this
supplement)]. It is good practice that Parties clearly define organic soils and use this definition consistently overtime. All other soils are classified as mineral soils following Annex 3A.5, Chapter 3 in Volume 4 of the 2006
IPCC Guidelines.
Under WDR, drainage and rewetting refer to all practices that directly affect the hydrological system, leading toa change in the mean annual water table in the organic soil. Drainage includes both new drainage of formerly
undrained land and a change in an existing drainage regime, whereas rewetting includes partial and total reversalof drainage (hereafter addressed as ‘partial’ and ‘total rewetting’, respectively). In case of WDR, these practices
and their results are only considered, as far as the practices have taken place since 1990. Chapter 2 of the
Wetlands Supplement provides methodological guidance for drained and partially rewetted organic soil. Partial
rewetting is referred to as a change in drainage class that results in a shallower water table. Chapter 3 of the
Wetlands Supplement provides methodological guidance for organic soil totally rewetted to near-natural watertable level. Chapter 4 of the Wetlands Supplement provides methodological guidance for drainage and rewettingof organic soils in coastal areas.
Human-induced drainage includes, for example, the installation of (additional) ditches or drainage pipes.
Additionally, groundwater extraction in and outside of the organic soil area may result in drainage. Direct
human-induced rewetting includes, for example, blocking drainage ditches and pipes or disabling pumping
facilities. Also, a decision that leads to abandoning the maintenance of ditches and results in water table rise isconsidered to be direct human-induced rewetting. Relevant information that WDR activities included in theidentified lands are direct human-induced includes documentation that a decision has been taken that aimed at or
implied altering the water table, for example referencing laws, policies, regulations, management plans,decisions and practices. Naturally rising or falling water tables, for example as a result of natural succession orriver/coastal erosion, are not considered to be direct human-induced rewetting or drainage. The WDR activity
includes only lands that are not accounted for under any other activity. Emissions and removals due to drainage
or rewetting practices on organic soils will be reported under other KP activities (see Box 2.12.1) as follows:Emissions and removals from drainage and rewetting associated with a conversion from non-forest to forest
or from forest to non-forest land will be reported under A, R or D.

Emissions and removals from drainage and rewetting of land remaining under FM will be reported under FM.

Emissions and removals from drainage and rewetting on lands that meet the criteria for classification under
CM, GM or RV, will be reported under these activities if elected.

Flooded land (as defined in Section 7.3, Chapter 7, Volume 4 of the 2006 IPCC Guidelines) is not included
under this activity. CO2 emissions from rice cultivation are by priority reported under the CM activity, but may
be included under WDR when organic soils are rewetted for rice cultivation, and CM is not elected.
The guidance for estimating and reporting of emissions and removals resulting from drainage and rewetting
practices (i.e. emissions and removals from drained and rewetted land) is given in the 2006 IPCC Guidelines andthe Wetlands Supplement (see Footnote 1, Section 2.1 of this supplement). The Wetlands Supplement introduces
updated emission and removal factors and new sources of off-site CO2 emissions and CH4 emissions fromditches for drained organic soils.
The base year for WDR is the same as for CM, GM and RV. Practical guidance for identification of land areas
for WDR in the base year and during the commitment period is given in Section 2.12.3 of this supplement.

Chapter 2: Methods for estimation, measurement, monitoring and reporting

The practices of drainage and rewetting result in immediate changes of GHG emissions and removals so that
there may be less need to establish a land-use history prior to 1990 for Tier 1 methods.
BOX 2.12.1
EXAMPLES FOR REPORTING OF EMISSIONS AND REMOVALS FROM DRAINED OR REWETTED ORGANIC SOILSUNDER THE VARIOUS KP LULUCF ACTIVITIES

Whereas the activity WDR – if elected - only applies to lands on organic soils that have been
drained or rewetted since 1990 and that are not subject to any other mandatory or elected activity,
the practices of drainage and rewetting of organic soils may occur under any other activity under
Articles 3.3. or 3.4 and would be reported under these mandatory or elected activities accordingly.
The resulting emissions and removals from drained or rewetted lands on organic soil would, forexample, be reported under:
D when• a forest with organic soil is drained and converted to e.g. cropland• forest harvesting affects hydrologic conditions to the extent that regeneration to forest is not
anymore possible (e.g. when reduced evapotranspiration and consequent higher water tables
after clear felling prevent re-establishment of forest)• rewetting practices change the hydrologic conditions to the extent that forest cannot persist or is
not allowed to regenerate (e.g. when forest with organic soils is rewetted and felled to enhance
specific biodiversity)
AR when• land other than forest is drained for forestry (e.g. when a naturally treeless or sparsely treedorganic soil is drained to stimulate forest growth)• land other than forest is rewetted for forestry (e.g. when drained organic soil used for grassland isrewetted and planted with wetland trees, e.g. alder/Alnus)
FM when• a forest is drained and remains a forest (e.g. when unproductive forested organic soil is drained toincrease productivity)• a forest is rewetted and remains a forest (e.g. when an ash/Fraxinus forest on organic soil isrewetted for alder/Alnus forestry)CM (if elected1) when
• land other than forest is drained for agriculture (e.g. when a treeless peatland is converted tocropland)• cropland is rewetted but remains cropland (e.g. when a potato field on organic soil is rewetted for
paludiculture)
GM (if elected1) when
• land other than forest is drained to improve grazing• grassland on organic soil is rewetted but remains grassland (e.g. when a drained grassland fordairy cow husbandry is converted to a wet grassland for water buffalo husbandry)
RV (if elected1) when
• land other than forest is revegetated and rewetted (e.g. when an abandoned bare peat extraction
site is actively converted to a vegetated wetland)
WDR when• land other than forest land is rewetted and is not subject to any other mandatory or elected
activity.

Base year

Managed land on organic soils in the base year is identified with the criteria set out in Section 2.12.3 of the KP
Supplement. These include the, land-use category, the status of the organic soils, in particular a stratification oforganic soils that are drained, eventually further stratified by drainage class and nutrient status, and wet organicsoils.
Drainage and rewetting practices on organic soils can lead to large changes in GHG emissions and removals per
hectare (Tuittila et al., 1999; Drösler, 2005). Consequently, particular care must be taken to make accurate
estimates of GHG emissions and removals both in the base year and in the commitment period.
It is good practice to use the same methodologies for estimating emissions and removals in the base year and in
all years of the commitment period.

G ENERAL GUIDANCE FOR IDENTIFYING LAND S

The activity WDR can only be applied to organic soils that are drained or rewetted since 1990 and that are notincluded under any other mandatory or elected KP activity (see Chapter 1 and Figure 2.12.1 of this supplement
for further guidance).

Chapter 2: Methods for estimation, measurement, monitoring and reportingAs drainage or rewetting of organic soils may also occur under other accounted land-use activities, the WDR
activity will always concern only a subset of the total area of organic soil in the country. When drained organic
soil oxidizes, the organic soil layer becomes shallower. Over time the organic soil layer may become so shallowthat an area no longer complies with the criteria of an organic soil. It is good practice to apply the activity to allland with an organic soil that has been drained or rewetted since 1990 even if the soil on these lands hasconverted to mineral soil before or in the commitment period. These issues are illustrated in Box 2.12.2.

to those lands that have been drained and rewetted since 1990 (c) and that are not included in any
other activity (d). The land that will be reported under WDR (if elected) is thus the hatched area.
Emissions and removals from the same land are to be reported both for the base year and for thecommitment period year.

Countries are encouraged to use stratification by land-use category or similar or further subcategories in a waythat the guidance in the Wetlands Supplement (see Footnote 1, Section 2.1 of this supplement) on methodologies
and emission factors best matches the national conditions.
It is good practice for Parties to describe the criteria used to identify areas where WDR applies and to apply
these criteria consistently (see Section 2.2 of this supplement).
With respect to the minimum area of 1 ha to which WDR applies, criteria can be defined as to the minimum
width. Then the minimum length of the area follows from the combination of width and the prescribed minimum
area of 1 ha. For example, with a minimum width of 20 m, a rectangle of minimum width has to be at least 500
m long to meet the 1 ha size requirement.

2.12.3.2

S PECIFIC GUIDANCE FOR IDENTIFYING LANDS

The identification of lands to be included under the WDR should follow a similar approach as described in
Section 2.2 of this supplement (see also decision tree in Figure 2.2.2). It is good practice to identify the lands
drained since 1990 and the lands rewetted since 1990 separately.
There are two ways of identifying lands subject to WDR:

2.168

2013 Revised Supplementary Methods and Good Practice Guidance Arising from the Kyoto Protocol

Chapter 2: Methods for estimation, measurement, monitoring and reporting

OPTION 1
All managed lands with organic soils in 1990 are compared with all managed lands with organic soils in thecommitment period, using the following steps:
STEP 1: Identify the area of managed land on organic soil separately for 1990 and for the commitment period.
Information can be taken from the UNFCCC inventory. WDR may occur on the lands identified for 1990 and forthe commitment period minus the land reported under any other Article 3.3 or 3.4 activity in the commitment
period.
STEP 2: Define water table sub-categories (e.g. deeply-drained, shallowly-drained, wet, at a minimum coveringdrained and wet as defined by the Wetlands Supplement) and stratify the land defined in Step 1 according tothese sub-categories for both 1990 and the commitment period. Data and information from the past can be oflower quality than recent data, whereas data sets may also be incomplete or not available for all years. Section
5.4 in Volume 1 of the 2006 IPCC Guidelines provides guidance for how to provide consistent time series inthese cases. Water table classes can be identified on the basis of proxies/indicators (e.g. groundwaterobservations, land use, management practice).
STEP 3: Identify areas of land where a change in water table subcategory occurred between 1990 and thecommitment period (wet-dry/dry-wet transition matrix), while complying with the minimum area and land
tracking requirements for WDR (see Section 2.2). When, for higher tiers, transitional emission factors areapplied for recently drained or rewetted land, it may be necessary to construct a transition matrix including moredisaggregated water table classes, time since drainage or rewetting and other characteristics relevant to emissions
and removals as described in Section 2.12.2.4 of this supplement.

OPTION 2
The areas of managed lands with organic soil where direct human-induced drainage or (partial) rewetting hastaken place since 1990 are directly identified, using the following steps:
STEP 1: Identify the area of managed land on organic soil in 1990 and in the commitment period. Information
can be taken from the UNFCCC inventory. WDR may occur on the areas identified for 1990 and for thecommitment period minus the area reported under any other Article 3.3 or 3.4 activities in the commitment
period.
STEP 2: Within the area identified in Step 1, identify the areas where a direct human-induced drainage orrewetting has occurred since 1990, while complying with the minimum area and land tracking requirements for
WDR (see Section 2.2 of this supplement). Identify lands where drainage and lands where rewetting has takenplace separately (wet-dry/dry-wet transition matrix). Approach 2 will result in a non-spatially explicit land use
matrix, while Approach 3 is spatially explicit.
STEP 3: Identify for the lands identified in Step 1 the magnitude of changes in water table by drainage orrewetting. This can include changes in water table classes (e.g. deeply-drained, shallowly-drained, wet, at aminimum covering drained and wet).
For both options 1 and 2, all the lands thus identified fall under WDR both in the base year (i.e. when thepractice of rewetting or drainage may not yet have taken place) and in the reporting year of the commitment
period. Therefore, the land under WDR in the base year must match the land under WDR in each reporting yearof the commitment period. Land that has been reported under CM or GM in the base year but not in any year of
the commitment periods is included in WDR only in the commitment period to avoid double-counting with CM
or GM in the base year. As the area of land under WDR may grow during the commitment period when newly
drained or newly rewetted lands are added, the area of land under WDR in the base year also has to growaccordingly. For QA/QC, identify the geographical boundaries and areas of managed lands on organic soils inthe base year and for the commitment period. It is good practice to provide information on changes in thereported area of managed organic soils (see also Box 2.12.1 of this supplement).

2.12.3.3

G EOGRAPHICAL BOUNDARIES

A country that elects WDR must identify geographic boundaries of all areas of land on organic soil that havebeen subject to the practices of directly human-induced drainage or rewetting (see Section 2.12.1 of this
supplement) since the base year that are one hectare or larger, and do not fall under any other activity that takes
precedence.
Either Approach 2, with supplementary information, or Approach 3, as described in Section 3.3.1, Chapter 3,
Volume 4 of the 2006 IPCC Guidelines, can be chosen to identify land area. For Approach 2, existing
administrative records, land-use databases and soil maps may have relevant information to identify the relevant
combinations of land-use categories and management practices with drained or rewetted status and their changes

2013 Revised Supplementary Methods and Good Practice Guidance Arising from the Kyoto Protocol

2.169

Chapter 2: Methods for estimation, measurement, monitoring and reporting

over time. It may be necessary to obtain additional data through sampling or other methods to allow the creationof a detailed non-spatially explicit land-use matrix for the WDR activity that tracks changes in land use anddrainage status over time.
Information sources about drainage and rewetting practices since 1990 with adequate disaggregation may include:National land use registries and statistics, land-use maps and soil maps, maps of water and nature
conservation zones with restrictions for water management and maps of wetlands.



National water management statistics: in most countries, the agricultural land base including croplands issurveyed regularly, providing data on distribution of different land uses, crops, tillage practice and otheraspects of management, often at sub-national or regional level. These statistics may originate, in part, fromremote sensing methods, from which additional information about wetness or periods with flooding could be
extracted.

Inventory data from a statistically-based, plot-sampling system of water table wells, ditches and surface
waters on organic soils that allow interpretation of data in terms of human-induced drainage and rewetting
rather than inter-annual variability.



Water management plans and documentation from water management installations. Information on theeffects of groundwater extraction on neighbouring water levels is generally available in the licensing for
groundwater extraction.

Drainage maps.

Maps of rewetting projects including remote sensing.

2.12.3.4

S TRATIFICATION

Stratification needs to be consistently applied in the base year and the commitment period. The following criteria
may be useful in establishing a national stratification for drained and rewetted land, which result in different
levels of GHG emissions or removals:
Land use and management practices, as relevantDrainage regime (water level, seasonality), following the water table classes defined in the first steps of theoptions 1 and 2 (Section 2.12.3), respectively, e.g.
(i)undrained /near natural water regime (Chapter 3 of the Wetlands Supplement),(ii)

drained comparable to the typical water table range of the Wetlands Supplement for drained organicsoils (Chapter 2 of the Wetlands Supplement),(iii)

drained deeper than water level range of Wetlands Supplement for part or all of the year if
applicable,(iv)

drained more shallowly than the water table range of Wetlands Supplement for partially drained or
rewetted for part or all of the year if applicable,(v)

flooded land (maybe further stratified by seasonally flooded or flooded throughout the year), if
applicable, which does not fall under the definition of “flooded land” or “reservoir” (See Section
7.1, Chapter 7 in Volume 4 of the 2006 IPCC Guidelines).

For all resulting subcategories where drainage and rewetting have taken place, the areas afforested, reforested ordeforested since 1990 need to be tracked separately as these areas will be reported as lands subject to theactivities AR and D. Similarly areas under FM or any elected activity need to be tracked and reported separately.
At higher tiers further subdivision of the area under WDR may be useful, e.g. by seasonality of drainage
management.

2.12.4

Choice of methods for estimating GHG emissions andremovals

Guidance on methodologies for estimating carbon stock changes, CO2 emissions and removals and non-CO2
GHG emissions on land subject to WDR is given in the 2006 IPCC Guidelines supplemented by the Wetlands
Supplement. The 2006 IPCC Guidelines provide methodologies for the estimation of carbon stocks and carbon
stock changes in above- and below-ground biomass, dead wood and litter for inland organic soils, whereas

2.170

2013 Revised Supplementary Methods and Good Practice Guidance Arising from the Kyoto Protocol

Chapter 2: Methods for estimation, measurement, monitoring and reporting

Chapter 4 of the Wetlands Supplement provides additional guidance for these pools for coastal organic soils. The
Wetlands Supplement provides methodologies and updated emission factors for estimating emissions andremovals from organic soils. Chapter 2 of the Wetlands Supplement provides guidance for drained inland organicsoils, Chapter 3 of the Wetlands Supplement for rewetted and wet inland organic soils and Chapter 4 of the
Wetlands Supplement for coastal organic soils.
It is good practice to estimate and report GHG emissions from drained organic soils (Chapter 2 of the Wetlands
Supplement) and from rewetted organic soils (Chapter 3 of the Wetlands Supplement) under WDR separately.
Generic guidance about the choice of methods is given in Section 2.3.6 of this supplement. For key category
analysis, the absolute values of emissions and removals from all land under WDR are summed. WDR is a key
category if (1) this sum is greater than the emissions from the key category with the smallest emissions as
identified in the UNFCCC inventory (including LULUCF) (= level analysis) or (2) the trend (change over time)of WDR is larger than that from the key category with the smallest changes (= trend analysis).
If WDR is a key category, it is good practice to determine whether one of the two subcategories rewetting or
drainage is particularly important. Following decision trees in Figures 1.2 and 1.3 in Chapter 1, Volume 4 of the2006 IPCC Guidelines, a subcategory is considered significant if it accounts for 25-30 percent of the overall
emissions or removals of the category (which applies to at least one of the two subcategories drainage orrewetting). It is good practice to report the significant subcategories with higher tier methods and to focus efforts
towards methodological improvements on these subcategories.
Detailed guidance is found:

for above-ground and below-ground biomass, dead wood and litter on organic soils in Volume 4 of the 2006
IPCC Guidelines in Chapter 2 (generic), Chapter 4 (Forest Land), Chapter 5 (Cropland), Chapter 6(Grassland), Chapter 7 (Wetlands) and Chapter 8 (Settlements), as well as Chapter 4 of the Wetlands
Supplement (coastal wetlands).

for non-CO2 GHG emissions from biomass burning by controlled burning and wildfires in the under therespective land-use categories in the 2006 IPCC Guidelines.



for off-site CO2 emissions from peat extraction for horticulture and soil amendment: Chapter 7, Volume 4 of2006 IPCC Guidelines for Tier 1. Countries using higher tier methods that deviate from the Tier 1
assumption that the peat is fully oxidized during the extraction year need to document that no doublecounting takes place and that CO2 emissions from peat in horticultural use are taken into account.

for N2O emissions from drained organic soils: Chapter 2 of the Wetlands Supplement for inland organic soils;

Decision 2/CMP.7176 specifies that a Party may choose not to account for a particular pool in a commitment
period, if transparent and verifiable information is provided that demonstrates that the pool is not a source.

Chapter 2: Methods for estimation, measurement, monitoring and reporting

Requirements for reporting excluded pools and documenting that a pool is not a source can be found in Section
2.3.1 of this supplement.
It is good practice to use consistent methodologies and emission factors across ARD, FM and elected Article 3.4
activities.
It is good practice to use the same methodologies for estimating emissions and removals in the base year and in
all years of the commitment period.
Some of the CH4 and N2O emissions on agricultural soils as well as CO2 emissions from liming and urea
application are in most cases not reported under WDR but under the Agriculture Sector. When reporting theseemissions, it is good practice to ensure consistency, completeness and no double-counting under Agriculture or
WDR (see Section 2.4.4.2 of this supplement).

Glossary

Accounting
The rules for comparing emissions and removals as reported with commitments.

Approach
The way in which areas are represented and reported for land-use categories, and conversions between land-use
categories, so that they are applied as appropriately and consistently as possible in inventory calculations. The
Intergovernmental Panel on Climate Change (IPCC) identifies Approaches 1, 2 and 3 of increasing geographic
specificity.

Background level
Under default assumptions, in forests this is the mean annual level of emissions from natural disturbances,
excluding statistical outliers, during a period before the second commitment period, called the calibration period.
The intention of using such a background level is to exclude, under specific conditions set by Decision 2/CMP.71,
emissions from natural disturbances in forests that exceed the background level plus a margin from accounting
during the commitment period. Providing the expectation of net credits or debits is avoided, countries may
develop other types of background levels using their country-specific methods for excluding natural disturbanceemissions from accounting.

Base year
A year with a historical level of anthropogenic emissions or removals of greenhouse gases not controlled by theMontreal Protocol, that is used as a reference under the United Nations Framework Convention on Climate
Change or the Kyoto Protocol.

Carbon Equivalent Forest Conversi on (CEFC)
The conversion of forest plantation to non-forest while simultaneously establishing a “Carbon Equivalent Forest”
on non-forest land elsewhere, under the terms of Decision 2/CMP.72. The “Carbon Equivalent Forest” must beof at least equal area and at least equal stock at the end of the normal harvesting cycle of the plantation forest
cleared, or a debit will be incurred under Article 3.4.
CEF-ne land: Land on which a Carbon Equivalent Forest is newly established as part of a Carbon Equivalent
Forest Conversion under the terms of Decision 2/CMP.7.
CEF-hc land: Land on which a forest plantation is harvested and converted to non-forest as part of a Carbon
Equivalent Forest Conversion under the terms of Decision 2/CMP.7.

Cropland
Arable and tillage land, and agro-forestry systems where vegetation falls below the threshold used for the Forest
Land category, consistent with the selection and application of national definitions.

Cropland Management 3
The system of practices on land on which agricultural crops are grown and on land that is set aside or
temporarily not used for crop production.

Elective activities
Article 3.4 activities that are not mandatory, but can be elected by a country for a commitment period. For thesecond commitment period, these are Cropland Management, Grazing Land Management, Revegetation, andWetland Drainage and Rewetting. Any 3.4 activities elected in the first commitment period are mandatory in thesecond commitment period.

Estimation

2013 Revised Supplementary Methods and Good Practice Guidance Arising from the Kyoto ProtocolGlossary

Statistical definition: Estimation is the assessment of the value of a quantity or its uncertainty through theassignment of numerical observation values in an estimation formula, or estimator. The results of estimation canbe expressed as follows:a point estimation which provide a number which can be used as an approximation to a parameter (such as
the sample standard deviation which estimates the population standard deviation), oran interval estimate specifying a confidence level.

Example: A statement like ‘The total emission is estimated to be 100 kt and its coefficient of variation is 5%’ isbased upon point estimates of the sample mean and standard deviation, whereas a statement such as ‘The total
emission lies between 90 and 110 kt with probability 95%’ expresses the results of estimation as a confidence
interval.

Forest cover
Tree cover that meets or exceeds the country-specific thresholds for defining forest, consistent with Decisions
16/CMP.1 and 2/CMP.74.

Forested land
Land containing forest according to the country-specific definition of forest, consistent with Decisions 16/CMP
and 2/CMP.75.

Forest Management Reference Level (FMRL)
The value of annual net emissions and removals from Forest Management against which the net emissions andremovals reported for Forest Management will be compared for accounting purposes during the second
commitment period.

Georeferencing
Georeferencing is the process of identifying the physical location of a particular area of land (e.g. that subject to
Article 3.3 or 3.4 activities) in terms of map projections or coordinate systems. It determines the spatial locationof geographical features in terms of size and configuration.

Good practiceGood Practice is a set of procedures intended to ensure that greenhouse gas inventories are accurate in the sensethat they are systematically neither over- nor underestimates so far as can be judged, and that uncertainties are
reduced so far as practicable.
Good Practice covers choice of estimation methods appropriate to national circumstances, quality assurance andquality control at the national level, quantification of uncertainties and data archiving, and reporting to promotetransparency.

GrasslandThis category includes rangeland and pasture land that is not considered as Cropland. It also includes systems
with vegetation that fall below the threshold used in the Forest Land category and is not expected to exceed,
without human intervention, these thresholds. This category also includes all grasslands from wild land torecreational areas as well as agricultural and silvo-pastural systems, which are subdivided into managed andunmanaged land, consistent with national definitions.

Grazing Land Management 6
The system of practices on land used for livestock production aimed at manipulating the amount and type ofvegetation and livestock produced.

Glossary

Gross-net accounting
Accounting based on greenhouse gas emissions or removals in the reporting year, without subtracting base year
emissions or removals. This is the accounting method used for Afforestation, Reforestation, and Deforestation
activities under Article 3.3.

Half-life
The number of years it takes to lose one-half of the material currently in the carbon pool.

Hierarchical order
See Reporting Hierarchy.

Indirect effects
The effects on emissions by sources and removals by sinks caused by climate change, raised CO2 concentrations,age legacy, and atmospheric nitrogen deposition. According to Decision 16/CMP.1 removal resulting fromindirect effects are to be excluded from accounting of LULUCF activities under Articles 3.3 and 3.4 of the
Kyoto Protocol7.

Interannual variability
The variation of GHG emissions by sources and removals by sinks, or a shift from being a net sink to a net
source from year to year, caused by significant fluctuations or abrupt changes in environmental conditions due tonatural disturbances and climatic abnormality, such as wild fire, pest and pathogen attacks, drought, flooding,and extreme temperatures. Interannual variability in emissions and removals can also be caused by fluctuations
in human activities such as timber harvesting or land-use change.

Land 8The areas subject to the activities defined under Article 3.4, namely Forest Management, Cropland Management,
Grazing Land Management, Revegetation, and Wetland Drainage and Rewetting. The methodological treatmentof land identification in Chapter 4 of the GPG-LULUCF is the same for units of land (see below) and land. ThisKP Supplement unites the concepts to simplify the text.

Land rehabilitation
The process of returning land back to the state it was prior to a natural disturbance. This process can, but notnecessarily must, involve active management, planning or legal processes, or abstention from activities.

Management practiceAn action or set of actions that affect the land, the stocks of pools associated with it or otherwise affect theexchange of greenhouse gases with the atmosphere.

Mandatory activities
The activities defined under Article 3.3, namely Afforestation, Reforestation, and Deforestation, as wells as (forthe second commitment period) Forest Management, and those Article 3.4 activities that were elected by acountry in the previous commitment period.

Margin (for background level under Decision 2/CMP.7)
This is a specific value that is to be used, when needed, in combination with the background level to identify
years during the commitment period in which a country may exclude emissions from natural disturbances inforests from accounting, under specific conditions set by the Decision 2/CMP.7. Such years are those in whichemissions from natural disturbances in forests are larger than the background level plus the margin.

Natural disturbances 9
The non-anthropogenic events or non-anthropogenic circumstances that cause significant emissions in forests
and are beyond the control of, and not materially influenced by, a Party. These may include wildfires, insect anddisease infestations, extreme weather events, and/or geological disturbances.

Net-net accounting
The greenhouse gas emissions or removals in the reporting year minus the greenhouse gas emissions or removals
in the base year. This is the accounting method for Grazing Land Management, Cropland Management,
Revegetation, and Wetland Drainage and Rewetting under Article 3.4.

Other Land
This category includes bare soil, rock, ice, and all unmanaged land areas that do not fall into any of the other fivecategories. It allows the total of identified land areas to match the national area, where data are available.

PastureGrassland planted and/or managed for grazing.

Planted forest
Land meeting the country definition of planted forest, which include forest plantations as defined in the 2006
IPCC Guidelines (Annex 4A.1, Chapter 4, Volume 4).

Remote sensing
The practice of acquiring and using data from satellites and aerial photography to infer or measure land cover orinfer land use. It may be used in combination with ground surveys for estimation, or to check the accuracy ofinterpretation.

Reporting
The process of providing estimates to the UNFCCC.

Reporting hierarchy
An ordered assignment of all activities under Article 3.3 and 3.4 and land subject to those activities. According
to Decision 2/CMP.610 and Decision 2/CMP.7, for reporting consistency and transparency, mandatory activities
take precedence over elective activities, Afforestation, Reforestation, and/or Deforestation activities takeprecedence over Forest Management activity. Parties determine the hierarchy among elected Article 3.4
activities. (See Section 1.2 for further explanation).

Reporting Method 1
The method of reporting information on geographical boundaries of areas encompassing lands subject to Article
3.3 and 3.4 activities that entails delineating areas that can include multiple lands subject to Article 3.3 and 3.4
activities by using legal, administrative, or ecosystem boundaries. This stratification is based on samplingtechniques, administrative data, or grids on images produced by remote sensing techniques. The identified
geographic boundaries must be georeferenced.

Reporting Method 2
The method of reporting information on geographical boundaries of areas encompassing lands subject to Article
3.3 and 3.4 activities that is based on the spatially-explicit and complete geographical identification of all lands
subject to Article 3.3 activities and all lands subject to Article 3.4 activities.

Salvage logging
The practice of harvesting and removing trees or parts of trees (living or dead) from disturbed areas. This
management activity is also known as salvage cutting, salvage harvesting, sanitation cutting, and otherdesignations. If it is conducted on areas which are not subject to the application of the natural disturbanceprovisions, it can be part of the regular forest management emissions and removals estimation and accounting

9

In the context of the Kyoto Protocol, as stipulated by Decision 2/CMP.7 (Land use, land-use change and forestry), cf.
paragraph 1 (a) of the Annex to Decision 2/CMP.7 (Land use, land-use change and forestry) contained in document
FCCC/KP/CMP/2011/10/Add.1, p 13.

framework, i.e. salvage logging would then be treated as harvest. In the case the Party chooses to exclude
emissions due to natural disturbances, it shall account for emissions associated with salvage logging11.

Technical Correction
The value of net emissions and removals, which is added, at the time of accounting, to the original Forest
Management Reference Level to ensure that accounted emissions and removals will not reflect the impact of
methodological inconsistencies. Information on Technical Correction and methodological consistency shall bereported as part of the annual GHG inventories and inventory reports.

Units of land 12
The areas subject to the activities defined under Article 3.3, namely Afforestation, Reforestation, andDeforestation. The methodological treatment of land identification in Chapter 4 of the GPG-LULUCF is thesame for units of land and land. This KP Supplement unites the concepts to simplify the text.

Wall-to-wall mapping
The complete spatial coverage of a land area, e.g. by satellite data.

wetland‘wetland’ is used to refer to land with a wet soil.

Wetland Drainage and Rewetting

13

A system of practices for draining and rewetting on land with organic soil that covers a minimum area of 1
hectare. The activity applies to all lands that have been drained since 1990 and to all lands that have beenrewetted since 1990 and that are not accounted for under any other activity as defined in Annex to Decision
2/CMP.7, where drainage is the direct human-induced lowering of the soil water table and rewetting is the direct
human-induced partial or total reversal of drainage.
