2019 Refinement to the 2006 IPCC Guidelines
for National Greenhouse Gas Inventories
IPCC TFI Side Event
Climate Change Conference COP22/CMP12/CMA1
7 November 2016
Marrakech, Morocco

Technical Support Unit, IPCC TFIBackground• Technical assessment of IPCC Inventory Guidelines was carried out
through an on-line questionnaire survey and four expert meetings in2015-2016• It revealed that there has been abundant new scientific and empiricalknowledge published since 2006
• Necessity and usefulness of refinement of the current methodologicalguidance (e.g. updating default emission factors) has been recognizedby Task Force Bureau (TFB)• A proposal on “Refinement of 2006 IPCC Guidelines for National
Greenhouse Gas Inventories, including production of a Methodology
Report(s)” was considered by the IPCC at its 43rd Session (IPCC-43)
held on 11-13 April 2016 in Nairobi, Kenya

Refinement of the 2006 IPCC Guidelines• The overall aim of the refinement work is to provide an updated andsound scientific basis for supporting the preparation and continuous
improvement of national greenhouse gas inventories
Provide supplementary methodologies for sources or sinks of greenhousegases only where currently there are gaps or where new technologies
and production processes have emerged requiring elaborated
methodologies or for sources or sinks that are not well covered by the2006 IPCC Guidelines– Provide updated default values of emission factors and other parameters
based on the latest available science only where significant differencesfrom currently adopted factors are identified– Provide additional or alternative up-to-date information and guidance,
where possible, as clarification or elaboration of existing guidance in the2006 IPCC Guidelines–

Methodology Report(s)• IPCC-43 approved the TFI’s proposal, and decided to consider theoutline of the Methodology Report(s) at the IPCC-44 in October 2016
and to consider the draft Methodology Report(s) at a Plenary sessionof the IPCC in May 2019

Strategic Planning– Decision IPCC/XLIII-8. Update of Methodologies on National Greenhouse

http://www.ipcc.ch/scripts/_session_template.php?page=_43ipcc.htm• IPCC-43 also approved the proposal to hold a scoping meeting before
the IPCC-44 in 2016 for the preparation of the Methodology Report(s)in order to consider the scope and format of the report(s)Scoping Meeting for a Methodology Report(s)• A call for nominations was issued on 12 May 2016
–198 nominations: 59 Member States, 11 Observer Organizations, andmembers of IPCC Bureau and TFB• Scoping meeting for a Methodology Report(s) to refine the 2006 IPCC
Guidelines was held on 29-31 August 2016 in Minsk, Belarus
Attended by 94 experts who were selected by TFB from 198 nominees,
and also attended by 14 members of TFB and 7 members of TFI TSU– Aimed to consider the scope and format of the Methodology Report(s),and to prepare draft terms of reference, draft table of contents anddraft work plan for the Methodology Report(s)– Took full account of issues identified by the four technical assessment
expert meetings held in 2015 and 2016 as well as decisions taken at theIPCC-43–• Meeting report will be available at TFI’s website

Scope and Outline of the Methodology Report(s)• The outcome of the scoping meeting was considered by TFB at its 28thmeeting (TFB28) which was held on 1-2 September 2016, Minsk,
Belarus–

Summary of the TFB28 is available at TFI’s website
http://www.ipcc-nggip.iges.or.jp/• A proposal on the scope and outline of the Methodology Report(s) torefine the 2006 IPCC Guidelines as contained in the document IPCCXLIV/Doc.12
http://www.ipcc.ch/scripts/_session_template.php?page=_44ipcc.htm• Considered and approved at IPCC-44 (17-20 October 2016, Bangkok,
Thailand)–Decision IPCC/XLIV-5. Sixth Assessment Report (AR6) Products,

Decision IPCC/XLIV-5
The Intergovernmental Panel on Climate Change decides:
1.

To prepare a Methodology Report to refine the 2006 IPCC Guidelines for National
Greenhouse Gas Inventories with the following format and title:


2.

3.
4.
5.

The format should be one single Methodology Report comprising an Overview Chapter
and five volumes following the format of the 2006 IPCC Guidelines for National
Greenhouse Gas Inventories (2006 IPCC Guidelines).
The title of the Methodology Report should be “2019 Refinement to the 2006 IPCC
Guidelines for National Greenhouse Gas Inventories”.

To adopt the terms of reference for the production of a Methodology Report to refine
the 2006 IPCC Guidelines for National Greenhouse Gas Inventories as contained inAnnex 1 to this Decision.
To adopt the table of contents of the Methodology Report as contained in Annex 2 tothis Decision.
To take note of document IPCC-XLIV/INF.7.
That the budget for the production of this Methodology Report is as contained inDecision (IPCC/XLIV-1) on the IPCC Trust Fund Programme and Budget.

Terms of Reference• Sets out background, scope and approach
A refinement of the 2006 IPCC Guidelines is required as early as
possible in order to address the issues that were identified through thetechnical assessment. The refinement will help all UNFCCC Parties use
good practice inventory methodologies based on up-to-date scientificknowledge– The refinement work will not revise the 2006 IPCC Guidelines, but will
update, supplement and/or elaborate the 2006 IPCC Guidelines wheregaps or out-of-date science have been identified. The Methodology
Report will not replace the 2006 IPCC Guidelines, but will be used inconjunction with the 2006 IPCC Guidelines.
– The authors will follow Appendix 2 “Instructions to Experts and Authors”
to ensure a consistent and coherent approach across all the volumes orchapters, including the use of common terminology.
– Table 1 provides the time table (Work plan)–

Instructions to Experts and Authors• Intended as a guidance to experts contributing to a new Methodology
Report
The role of authors is to impartially assess all the available literature andto describe the best methodologies available. Authors should review all
literature available up to a cut-off date
– Guidance in the new Methodology Report should be understandable andeasy to implement– The general structure, approach and definitions used in the 2006 IPCC
Guidelines, such as tiered approach and decision trees will be followed– IPCC default factors should in principle be presented as regional factors.
In case regional factors are unavailable, single IPCC default factors might
be provided, ensuring that the defaults are representative of typicalconditions as far as can be determined. It may be necessary or
appropriate to provide a range of default factors along with clear guidance
about how countries should select from within the range.
–Draft Table of Contents• Structure is the same as that of the 2006 IPCC Guidelines• For those chapters/sections/subsections where refinement is expected,
the following three elements are explained:
Issue (which needs to be addressed)– Location in 2006 IPCC Guidelines (e.g. section, subsection, table)– Type of refinement (e.g. update, elaboration, new guidance)–Thank you
