IPCC Statement on Preparation of 2006 IPCC Inventory Guidelines
At the 19th Session of SBSTA, I had a pleasure of making a statement on this matter, in which
I talked of the IPCC Panel 21 approval of the Terms of Reference, Table of Content and theWork Programme for the revision of the Revised 1996 IPCC Inventory Guidelines – inresponse to the SBSTA 17’s invitation to IPCC. Since then, the IPCC has completed theselection of authors for this work, and more than 230 international experts are now engaged inthis very challenging work.
This year, IPCC has so far convened two meetings of authors, one on cross-cutting questions,and another on Agriculture, Forestry and Other Land Use. Three more sectoral authors
meetings are planned in 2004, and in 2005, there will be three authors meetings and two IPCC
review processes, one review by experts, and another review by Governments and experts.
We expect the final 2006 Guidelines will be accepted by IPCC Panel in early 2006, and will
be provided to SBSTA thereafter.
Let me briefly talk of the specificity of our undertaking:Firstly, the basis for the ”2006 IPCC Guidelines” will be the existing 1996 IPCC Guidelines
and the two IPCC good practice guidance reports. Experience and feedback in using theexisting reports and from the UNFCCC inventory reviews, as well as advances in science will
be taken into account in the preparation. UNFCCC documents, starting withSBSTA/2003/Inf.10 (also 2004/Inf. 2, 3, 4 and 7. Inf 5 is also some relevance for us), will becarefully studied by authors, and will be taken into account appropriately. The IPCC’s two
new Special Reports, i.e., “Safeguarding the ozone layer and the global climate system: issues
related to hydrofluorocarbons and perfluorocarbons” and “Carbon Dioxide Capture andStorage” will also serve as inputs to the “2006 IPCC Guidelines”.
As you may recall the Revised 1996 Guidelines had three volumes – the Reporting
Instructions, the Workbook and the Reference Manual. In the “2006 IPCC Guidelines”,
however, each sector – Energy; Industrial Processes and Product Use; Agriculture, Forestryand Other Land Use; and Waste; as well as the Cross-Cutting Issues and Reporting Tables would be each synthesised into single volume. The “Agriculture, Forestry and Other Land
Use” sector would encompass the Agriculture and Land-Use Change and Forestry sectors ofthe 1996 Guidelines, with a structure consistent with the IPCC Good Practice Guidance on
Land Use, Land-Use Change and Forestry.
New sources and gases will be included in “2006 IPCC Guidelines” according to criteria laidout in the Terms of Reference for the work: namely, availability of a Global Warming
Potential, identified anthropogenic sources, existing basis for methodology development,
ability to develop default emission factors, etc. Likewise, New Sources will be included if thefollowing criteria are true: Basis exists for methodological development including the abilityto develop default emission factors; It is feasible to obtain the necessary data to implement themethod; and the source is significant within the sector
Additional information on the scope and workplan for the preparation of the ”2006 IPCC
Guidelines” will be given at the IPCC NGGIP side-event on Thursday, 17th June at 1 – 3 pm.
