26th Meeting of the TFI Bureau
At its 26th meeting in August 2014 in Ottawa,the TFI Bureau (TFB) concluded: 2006 IPCC Guidelines provide a technicallysound methodological basis of national
greenhouse gas inventory, and therefore
fundamental revision is not necessary
 However, to maintain their scientific validity,
certain refinements may be required, taking into
account scientific and other technical advancesthat have matured sufficiently since 2006

43rd Session of the IPCC
• IPCC-43 (April 2016, Nairobi) approved the TFI’s
proposal on Refinement of 2006 IPCC Guidelines,
and decided to consider the outline of theMethodology Report(s) at the IPCC-44 in October
2016 and to consider the draft Methodology
Report(s) at a Plenary session of the IPCC in May
2019.
• IPCC-43 also approved the proposal to hold ascoping meeting before the IPCC-44 in 2016 forthe preparation of the Methodology Report(s) inorder to consider the scope and format of thereport(s).

Scoping Meeting• Scoping meeting for a Methodology Report(s) torefine the 2006 IPCC Guidelines was held on 2931 August 2016 in Minsk, Belarus. It was attended
by 94 experts selected by TFB from 198 nominees.
• It aimed to consider the scope and format of theMethodology Report(s), and to prepare draft termsof reference, draft table of contents and draft work
plan for the Methodology Report(s).
• Meeting report is available at TFI’s website
http://www.ipcc-nggip.iges.or.jp/

44th Session of the IPCC
• At its 44th Session in October 2016 in Bangkok, IPCC
decided to prepare a Methodology Report to refine the2006 IPCC Guidelines with the following format andtitle (Decision IPCC/XLIV-5):– The format should be one single Methodology Report comprising
an Overview Chapter and five volumes following the format of the 2006
IPCC Guidelines– The title of the Methodology Report should be “2019 Refinement tothe 2006 IPCC Guidelines for National Greenhouse Gas Inventories”(2019 Refinement)• During its 44th Session, the Panel approved the outlineof the 2019 Refinement.

Coverage and Structure• Coverage: All IPCC inventory sectors are covered but
refinements are included for only those categories wherethe science is considered to have sufficiently advanced
since 2006 or where new or additional guidance isrequired.
• Structure: Same as that of the 2006 IPCC Guidelines so
as to make it easier for inventory compilers to use the2019 Refinement with the 2006 IPCC Guidelines: Overview Chapter
 Volume 1: General Guidance and Reporting (GGR)
 Volume 2: Energy Volume 3: Industrial Processes and Product Use (IPPU)
 Volume 4: Agriculture, Forestry and Other Land Use (AFOLU)
 Volume 5: Waste

Aim of 2019 Refinement• The overall aim of the refinement of the 2006 IPCC
Guidelines is to provide an updated and soundscientific basis for supporting the preparation andcontinuous improvement of national greenhouse gas
inventories.
• The refinement work will not revise the 2006 IPCC
Guidelines, but will update, supplement and/orelaborate the 2006 IPCC Guidelines where gaps orout-of-date science have been identified.

• The 2019 Refinement will not replace the 2006 IPCC
Guidelines, but will be used in conjunction with the2006 IPCC Guidelines.

Official IPCC Procedures
The 2019 Refinement is being produced
through the official rigorous procedures towhich the official reviews are essential:• Expert Review of the First Order Draft (FOD)• Government and Expert Review of the Second Order
Draft (SOD)• Government Review of the Final Draft (FD)How the IPCC prepares its reports? (1)How the IPCC prepares its reports? (2)Scoping - Outline
