IPCC Inventory Guidelines
and UNFCCC＋Currently, Non-Annex I Parties use theseunder the UNFCCC.
Non-Annex I Parties are encouraged
to use GPGs.

1995 IPCC

Revised 1996 IPCCGuidelines

Actually, 2006 Guidelines are being usedby more and more Non-Annex I Parties.
Revision/Update by the IPCC

2006 IPCC
GuidelinesParis Agreement and National GHG Inventory• In order to build mutual trust and confidence among the Parties and topromote effective implementation of the Paris Agreement, atransparency framework for action needs to be enhanced.
• To that end, it is essential that all the Parties produce and report highquality and reliable national GHG inventories (national emission data).
• Paris Agreement
Article 13, paragraph 7:– Each Party shall regularly
provide …:(a) A national inventory
report of anthropogenicemissions by sources andremovals by sinks ofgreenhouse gases,
prepared using good practice methodologies acceptedby the Intergovernmental Panel on Climate Change and…

Need for refinement of 2006 IPCC Guidelines• 2006 IPCC Guidelines – 13 years ago!!

• In August 2014, TFI Bureau discussed and concluded:– The 2006 IPCC Guidelines provide a technically soundmethodological basis of national greenhouse gas inventory, andtherefore fundamental revision is not necessary.
– To keep the validity of the 2006 IPCC Guidelines, certain
refinements may be required, taking into account scientific andother technical advances that have matured sufficiently since 2006.

• In October 2016, IPCC decided to prepare a newMethodology Report titled “2019 Refinement to the 2006
IPCC Guidelines for National Greenhouse Gas Inventories”,
and adopted its table of contents. (Decision IPCC/XLIV-5)

2019 Refinement was produced following IPCC Procedures2019 Refinement was adopted/accepted by theIPCC at its 49th Session in May 2019 in Kyoto,
Japan. (Decision IPCC-XLIX-9)

2019 Refinement to the 2006 IPCC Guidelines
280

Prepared by over 280 scientists and experts.

47
10,000Participated by authors from 47 countries.

More than 10,000 review comments fromgovernments and experts were considered by authors.

Produced as one of the major IPCC products during its AR6 cycle.

2019 Refinement to the 2006 IPCC Guidelines• The 2019 Refinement provides an updated and soundscientific basis for supporting the preparation andcontinuous improvement of national greenhouse gas
inventories.
• The 2019 Refinement updates, supplements andelaborates 2006 Guidelines where the authors identified
gaps or out-of-date science. The 2019 Refinement is to be
used in conjunction with the 2006 IPCC Guidelines.

• Authors have examined a wide range of inventory
methodologies and updated them where scientific advancesand new knowledge made this necessary, following the IPCC
decision.

Structure of 2019 Refinement• The same structure as that of the 2006 IPCC Guidelines soas to make it easier for inventory compilers to use the 2019
Refinement with the 2006 IPCC Guidelines.
• Comprising an Overview Chapter and five volumes:– Vol.1: General Guidance and Reporting (GGR)– Vol.2: Energy– Vol.3: Industrial Processes and Product Use (IPPU)– Vol.4: Agriculture, Forestry and Other Land Use (AFOLU)– Vol.5: Waste• Glossary is also included.

Key concepts unchanged from 2006 Guidelines• Relevant but not prescriptive with respect to the reporting of
national inventories under international agreements, and theuse of reported information under these agreements.
• Provides methods for estimating emissions for each gas inmass units. No specific metrics (e.g., GWP values) isrecommended to calculate emission estimates in CO2
equivalent units.
• Structured so that any country, regardless of experience orresources, should be able to produce reliable estimates of
their emissions and removals.

Relationship with 2006 IPCC Guidelines
Types of refinement from inventory compilers’ perspective
TypeExplanation

UpdateInventory compilers should use the chapter/section/subsection in the2019 Refinement instead of the corresponding
chapter/section/subsection in the 2006 IPCC Guidelines.

New Guidance

Recognizing that there is no guidance in the 2006 IPCC Guidelines,
inventory compilers should use the chapter/section/subsection in the2019 Refinement.

No Refinement

Inventory compliers should use the corresponding
chapter/section/subsection in the 2006 IPCC Guidelines, because norefinement has been made in that chapter/section/subsection.

Removed

There were few cases where guidance/sections were removed because
they were no longer relevant.

2019 Refinement and Paris Agreement• “Katowice Climate Package” was adopted by the UNFCCC
COP24/CMA1 in December 2018 to operationalize the ParisAgreement. It stipulates:– Each Party shall use the 2006 IPCC Guidelines, and shall use any
subsequent version or refinement of the IPCC guidelines agreed
upon by the Conference of the Parties serving as the meeting of
the Parties to the Paris Agreement (CMA).
