ANNEX 1 – Terms of Reference, Chapter Outline & Work Plan as approved by IPCC 35

TERMS OF REFERENCE
Background1.
The UNFCCC Conference of the Parties serving as the meeting of the Parties to theKyoto Protocol (CMP) at its seventh session (CMP7), 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 andremovals by sinks resulting from land use, land-use change and forestry (LULUCF) activities
under Article 3, paragraphs 3 and 4, of the Kyoto Protocol (KP), related to the annex to2/CMP.7, on the basis of, inter alia, Chapter 4 of IPCC’s 2003 Good Practice Guidance forLand Use, Land-Use Change and Forestry (GPG-LULUCF).
2.
The need to review and update Chapter 4 of the GPG-LULUCF arises for tworeasons. Firstly, the methodologies contained in Chapter 4 provide the link between IPCC’s
general greenhouse gas inventory guidance, and reporting requirements under the KP.
CMP7 agreed rules for LULUCF for the second commitment period under the KP which
differ in some respects significantly from the rules agreed for the first commitment period,implying the need to update. Secondly, since Chapter 4 was intended to be used with thelatest IPCC LULUCF guidance updating is needed to take account of the decision of theCMP to use the 2006 IPCC Guidelines for the purposes of the second commitment period
under the KP.
3.
The new rules referred to and agreed by CMP7 on LULUCF contain, amongst otherthings, new provisions on forest management, emissions and removals associated withnatural disturbances in forests, harvested wood products, and wetland drainage andrewetting, which are not covered in the existing Chapter 4.
4.
The potential need to update Chapter 4 was considered at the IPCC Scoping
Meeting to consider the Invitation from UNFCCC CMP7 that took place in Geneva from 1 to4 May 2012. The scoping meeting concluded that, whilst much of the structure and thecontent of Chapter 4 remains relevant and useful, Chapter 4 needs significant updating totake account of the LULUCF decision 2/CMP.7, other relevant decisions by COP and CMP,
the 2006 IPCC Guidelines, IPCC’s work on wetlands, and other IPCC products. The authors
should take account of new scientific literature and methods.
Scope
5.
IPCC will update and augment the existing Chapter 4 of the GPG LULUCF, to takeaccount of the 2006 IPCC Guidelines and other IPCC products, the annex to 2/CMP.7, otherrelevant decisions of the COP and CMP, new scientific literature and methods, and theoutcomes of the scoping meeting held in Geneva on 1 to 4 May 2012.
Aim
6.
The overall aim of this work is to update and augment Chapter 4 of the GPG
LULUCF consistent with the scope identified in paragraph 5, intended for publication as aseparate report provisionally entitled “2013 Revised Supplementary Methods and Good
Practice Guidance Arising from the Kyoto Protocol”. This will ensure continued usefulness ofIPCC inventory methods in support of the reporting requirements of the KP during thesecond commitment period by providing practical guidance to countries in implementing theannex to 2/CMP.7 and any other relevant decisions of the COP or CMP, for example onreporting and accounting.

Approach7.
The result of this work will be an IPCC Methodology Report using the Table ofContents (below).
8.
The update will be consistent with the 2006 IPCC Guidelines and not revise orreplace the 2006 IPCC Guidelines.
9.
The report will provide methodological guidance on scientific and technical issues
covered by the scope indicated in paragraph 5 above, consistent with decisions of the COPand CMP.
10.
The report will maintain the structure and content of the existing Chapter 4, replacingreferences to GPG-LULUCF by those to 2006 Guidelines wherever necessary, and adding
additional material to existing sections or adding new sections using the Table of Contents(below).
11.
Literature will be considered up to a cut-off date at the start of theGovernment/Expert Review.
12.
There will be a Steering Group appointed by the TFB to ensure consistency withthese terms of reference.
