2019 Refinement to the 2006 IPCC Guidelines for National Greenhouse Gas Inventories
The development of the new Methodology Report to refine the current inventory guidelines (2006 IPCC Guidelines for National Greenhouse Gas Inventories), is being carried out by the Task Force on National Greenhouse Gas Inventories (TFI) in accordance with the decision taken at the 44th Session of IPCC in Bangkok, Thailand, in October 2016. The final draft of this new Methodology Report titled “2019 Refinement to the 2006 IPCC Guidelines for National Greenhouse Gas Inventories” (2019 Refinement) will be considered by the IPCC for adoption/acceptance at its Plenary Session in May 2019.
The 26th Meeting of Task Force Bureau (TFB) (28 - 29 August 2014, Ottawa) concluded that:
- The 2006 IPCC Guidelines for National Greenhouse Gas Inventories (2006 IPCC Guidelines) provide a technically sound methodological basis of national greenhouse gas inventories, and therefore fundamental revision is unnecessary.
- To maintain the scientific validity of the 2006 IPCC Guidelines, certain refinements may be required, taking into account scientific and other technical advances that have matured sufficiently since 2006.
Following these conclusions by the TFB and approval by the IPCC at its 40th Session, the TFI started a technical assessment of IPCC Inventory Guidelines through an on-line questionnaire survey and four expert meetings in 2015 and 2016. The Co-Chairs' summaries of these four meetings can be found below in Documents section. The technical assessment revealed that there has been abundant new scientific and empirical knowledge published since 2006 which the IPCC should take into account, particularly with respect to data for emission factor development for some categories and gases. Consequently, the necessity and usefulness of refining the current methodological guidance (e.g. updating default emission factors) has been recognized by TFB. Such refinement will help all UNFCCC Parties use good practice inventory methodologies based on up-to-date scientific knowledge.
Based on the decision of the IPCC at its 43rd session in April 2016, a Scoping Meeting was held to prepare an outline of the Methodology Report to refine the 2006 IPCC Guidelines.
The conclusions of this Scoping Meeting were submitted to the IPCC for consideration at its 44th Session. At this session, IPCC decided (Decision IPCC/XLIV-5) to prepare a Methodology Report with the following title and format:
- 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”.
- Decision includes also Draft Table of Contents (TOC) and "Terms of Reference for the production of a Methodology Report to refine the 2006 IPCC Guidelines for National Greenhouse Gas Inventories" (TOR).
Its overall aim is to provide an updated and sound scientific basis for supporting the preparation and continuous improvement of national GHG inventories.
The 2019 Refinement will not revise the 2006 IPCC Guidelines, but update, supplement and/or elaborate the 2006 IPCC Guidelines where gaps or out-of-date science have been identified. It will not replace the 2006 IPCC Guidelines. It should be used in conjunction with the 2006 IPCC Guidelines.
Among 328 nominations received from governments, observer organizations and Bureau members, 190 experts were selected as Authors and Review Editors by the TFB in accordance with the Principles Governing IPCC Work. After that, the list of authors has been slightly changed because of declination of some authors. The latest list of Authors and Review Editors is available below.
The authors started drafting the 2019 Refinement at the first Lead Author Meeting in June 2017 in Bilbao, Spain. The final draft will be considered by the IPCC for adoption/acceptance at its Plenary Session in May 2019.
