4. Possible cycle for production of Methodology Report

IPCC Materials
There are three main classes of the IPCC materials:
A. IPCC Reports(Assessment, Synthesis and Special Reports and their Summaries
for Policymakers and Methodology Reports)

B. Technical Papers(based on materials already exist in Assessment and SpecialReports)

C. Supporting Material(Workshop proceedings and expert meeting materials, Softwareand Database to facilitate the use of Methodology Reports,Guidance material)

IPCC Writing and Review Process• IPCC Reports
must beproducedthrough theofficial
rigorous
writing andreview
processObjectives of the IPCC TFI Work
The objectives of the IPCC Task Force on National
GHG Inventories are:• to develop and refine an internationally-agreed
methodology and software for the calculation andreporting of national GHG emissions and removals• to encourage the widespread use of this methodology
by countries participating in the IPCC and bysignatories of the United Nations Framework
Convention on Climate Change (UNFCCC)

IPCC TFI Work and Methodology Report
Two comprehensive Methodology Reports:
o 2006 IPCC Guidelines for National Greenhouse Gas
Inventories
o 1996 Revised IPCC Guidelines for National Greenhouse
Gas Inventories
 2000 GPG, 2003 LULUCF GPG, 2003 Degradation of Forests,
2013 Wetlands Supplement, 2013 KP Supplement

IPCC TFI Work (current)
IPCC-43 (Nairobi, Kenya, 11-13 April 2016) approved the IPCC TFI’s
proposal on Refinement of the 2006 IPCC Guidelines, including
production of a Methodology Report(s), [IPCC-XLIII/Doc. 6, Corr.1]:•

Refinement of the current available guidance is necessary in order to provide
an updated and sound scientific basis for future international climate actions,particularly those under the Paris Agreement•Refinement work will not revise the 2006 IPCC Guidelines, but will provide anupdate, supplement and/or elaboration of the 2006 IPCC Guidelines. The
outcome of this refinement work will not replace the 2006 IPCC Guidelines,
but would be used in conjunction with the 2006 IPCC Guidelines

IPCC TFI Work
A Methodology Report(s) as an output(s) of this refinement work willaddress the following three needs while avoiding a fundamental
revision of the 2006 IPCC Guidelines:• Providing supplementary methodologies for sources or sinks of greenhousegases only where necessary (e.g. for sources or sinks that are not well coveredby the 2006 IPCC Guidelines)• Providing updated default values of emission factors and other parameters basedon the latest available science only where significant differences from current
default values are identified• Providing additional or alternative up-to-date information and guidance, wherepossible, as clarification or elaboration of existing guidance in the 2006 IPCCGuidelines
 [IPCC-XLIII/Doc. 6, Corr.1], IPCC-43

IPCC TFI Work
IPCC-43 approved the IPCC TFI’s proposal to hold a scoping
meeting before the 44th Session of the IPCC in 2016 for thepreparation of the Methodology Report(s) in order to consider thescope and format of the report(s)Draft terms of reference, draft table of contents and draft work
plan for the proposed Methodology Report(s) will be prepared at
this scoping meeting, and will be submitted to the 44th Sessionof the IPCC for its consideration and approval in 2016
