WMO UNEP INTERGOVERNMENTAL PANEL ON CLIMATE CHANGE NATIONAL GREENHOUSE GAS INVENTORIES PROGRAMME WMO UNEP 2006 IPCC Guidelines Background and Objectives of the Revision of the “Revised 1996 IPCC Guidelines” Simon Eggleston Head Technical Support Unit for the IPCC National Greenhouse Gas Inventories Programme

Content  This Talk: Background, objectives and scope Outline of the 2006 IPCC GLs Work programme  More Detailed Presentations: AFOLU Sector (Leandro Buendia) EFDB (Tanabe Kiyoto)

Background  The “revised” 96 GLs were based on data and knowledge from the beginning of the 1990s Successful but now 10 years old  Two Good Practice Guideline reports to complement the 96GLs (2000 & 2003)  We now have Experience in use of GLs and GPG New scientific and technical developments

Therefore:  There is a need for a comprehensive update and revision  This could contribute to the future negotiations

Planning for Revision  TFB 8/TFB9/TFB10 first steps towards the revision  IPCC Bureau XXVII proposal for IPCC XX  SBSTA 17 invitation to IPCC to revise the 96GLs by 2006  IPCC XX approved the plan for the revision  Scoping meeting and TFB 11 (both in Geneva in September 2003)  TOR, TOC and Work Plan were approved by IPCC XXI (November 2003)

Objectives  Revise existing guidelines based on: Existing GL and GPG reports IPCC Emission Factor Database Experience and feedback in using guidelines as well as experience from UNFCCC inventory reviews (e.g.FCCC/SBSTA/2003/INF.10) Improvements in scientific and technical knowledge since mid 1990s

General Approach  96GLs and GPGs to be initially merged into one report  Recent advances in science as well as experience in use of the guidelines and results of the UNFCCC inventory reviews will be taken into account (such as; FCCC/SBSTA/2003/INF.10) A key principle will be to approach the revision with flexibility but to maintain the existing structure as much as possible to facilitate the job of inventory preparers (evolution not revolution)

Scope of Gases  Current coverage: CO 2, CH 4, N 2 O, HFCs, PFCs and SF 6 (direct GHGs) NO x, CO and NMVOCs and SO 2 (indirect GHG; precursors)  The 2006 Guidelines will cover these.  What About new gases?

 Vol. 1, IPCC 3 rd Assessment Report (TAR) “new” gases (i.e. not in SAR, e.g. halo-ethers) improved scientific understanding of atmospheric chemistry, including lifetimes and GWPs of GHGs.  Demands by Parties to the UNFCCC (e.g. FCCC/SBSTA/2003/MISC.3)  Development of Guidelines by other organizations (e.g. EMEP/CORINAIR) Developments since 1997/2000

 new halogenated direct GHGs e.g. halo-ethers, NF 3, SF 5 CF 3,  other indirect GHGs e.g. H2  other precursors and substances e.g. NH3, aerosols Candidate new gases for inclusion

Criteria for inclusion of a new gas  Scoping Meeting (Geneva, September 2003) agreed criteria for the inclusion of new gases: availability of a global warming potential in the TAR there are identified anthropogenic sources there is a basis for methodological development relative importance to the total emissions  A need for development for New methods for ozone precursors is not anticipated as these are addressed under other agreements and conventions.

Aerosols  Participants of the scoping meeting did not agree on whether or not to include the development of an annex on aerosol methodologies in the terms of reference of the 2006 IPCC Guidelines  The item was forwarded for decision to the IPCC Plenary  The IPCC Plenary decided, following a suggestion by the IPCC Chair, to convene an expert meeting before the next Panel meeting in 2004.

2006GLs - Aerosols  Aerosols (black carbon, organic carbon and mineral dust…) Not included in current outline Expert meeting in 2004 to assess possible scope (inclusion or non-inclusion) IPCC XXII to decide on possible inclusion

2006GLs – New Sources  New Sources will be included if the following criteria are true: Basis for methodological development including the ability to develop default emission factors exists It is feasible to obtain the necessary data to implement the method The source is significant within the sector.

IPCC Emission Factor Database (EFDB) (more by Kiyoto…)  Launched at COP8 – main objective to help inventory compilers, useful also for reviewers and other  Main criteria robustness, applicability and traceability (documentation)  Includes IPCC Default factors from 96GLs and GPG2000; defaults from GPG-LULUCF will be included 2004  Population with new data – input to revision process

Documentation – Default Data Author 1 IPCC Source/Sink Category Fuel 2 (applicable only in the Energy Sector): Gas 3 :CO 2 CH 4 N2ON2O Value: Unit: Uncertainty (as +/% or 2.5 and 97.5 percentiles ) 4 Applicability 5 – fill in as necessary if data not generally applicable. Describe appropriate Technologies, Practices, Abatement Technologies, Region, and/or Regional Conditions Source of data (chose one) Measurement - Scientific Literature / Other Measurement National Inventory Report / Calculated Based on fuel quality / Expert Judgement Reference 6

Volume 1: Cross-Cutting Issues and Reporting Tables Overview Approaches to Data Collection Uncertainties Methodological Choice and Identification of Key Categories Time Series Consistency and Recalculation Quality Assurance/Quality Control and Verification Reporting Guidance, including Tables

Overview and cross-cutting issues Reference Approach Stationary Combustion Mobile Combustion Fugitive emissions The coverage of CO 2 storage in will be coordinated with progress on IPCC SR on CO 2 capture and storage -the activities will be integrated as appropriate into the methods presented for source categories where it may occur. Emissions from international aviation and maritime transportation will take into consideration the relevant work of the International Civil Aviation Organization (ICAO) and the International Maritime Organization (IMO). Volume 2: Energy
