Procedures for the preparation, review, acceptance,approval, adoption and publication of IPCC reports&Question on the format of new Methodology Report(s)Scoping Meeting for a Methodology Report(s) to refine the 2006
IPCC Guidelines for National Greenhouse Gas Inventories
29-31 August 2016, Minsk, Belarus
Kiyoto Tanabe, IPCC TFIWhat are “Methodology Reports”?
• “Methodology Reports” are published materials, which
provide practical guidelines for the preparation ofgreenhouse gas inventories. Such reports may be composedof two or more sections including: (a) an Overview Chapter,which broadly describes the background, structure and major
features of the report, (b) individual chapters and (c)technical Annexes.
= Definition of “Methodology Reports” in the IPCC Procedures for thepreparation, review, acceptance, approval, adoption and publicationof IPCC reports (Appendix A to the Principles Governing IPCC Work)

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

It will take 2.5
years or moreQuestion on Format of new MR(s)• Paragraph 14 in the proposal on production of new MR(s)which was approved by the IPCC at its 43rd Session says:– Regarding the format of the Methodology Report(s), there are somepossible options. The options will be considered by the TFB during
the scoping meeting mentioned, before consideration and final
decision by the Panel. The options include, but are not limited to:a. A single Methodology Report which covers multiple
sectors/categories/issues
b. A set of multiple Methodology Reports, each of themaddressing a particular category/issue• This meeting is invited to consider this issue and recommend
a desirable format of the new Methodology Report(s).

Options and pros & cons
OptionStrong points•(a) A singleMethodologyReport whichcoversmultiple
sectors/categories/issues•(a) A set ofmultiple
Methodology •Reports, eachof themaddressing aparticular
category/issue

Weak points

Facilitate refinement work on
all sectors in a consistent and•coherent manner, as all theauthors will work as anintegrated writing team.
Can avoid multiple tracks of
IPCC procedures going
separately in parallel, which will
avoid increasing administrative
work and required budget.
•Each of Methodology Reports
may become more intensively
focused on a specific issue
than the option (a).

•May become more voluminous
than each of the option (b).
[However, a set of multiple
reports in total may well
become as voluminous as thisoption.]

Multiple tracks of IPCC
procedures going separately inparallel will significantly
increase administrative workand required budget.
Multiple writing processes
independent of each other may
lead to inconsistency oroverlapping between different
reports.
