  1. 2006 IPCC Guidelines - Overview Jim Penman Steering Group Member (UK Defra)

  2. Origins • OECD initiation (1992) => IPPC 1995 guidelines, updated 1996 • 1996 Guidelines adopted at COP3 • Supplemented by GPG in 2000 and 2003 • System adapted to actual needs - very widely used • Basis for 2006 Guidelines requested by SBSTA17.

  3. Structure of 2006 Guidelines Aims: • Rationalise structure by reducing number of volumes needed for cross referencing • Promote consistency between sectors • Resulting structure agreed at IPCC 21 (Vienna 2003):

  4. Volume structure Overview • Overview • Vol 1 - General Guidance and Reporting • Vol 2 - Energy • Vol 3 - Industrial Processes and Product Use • Vol 4 - Agriculture, Forestry and Other Land use • Vol 5 - Waste

  5. Approach • Evolution – users recognise familiar methods. • As with GPG basic principles for 2006 GL remain: 1) estimates neither under nor overestimates so far as can be judged 2) uncertainties reduced as far as practicable • Hence efficient use of resources

  6. Coverage As in IPCC 96 Guidelines, plus notably: • All GHG with available GWP values • Additional gases that could be used as substitutes for which GWPs not yet calculated • Carbon dioxide capture and storage • Methane from abandoned mines.

  7. Other developments • General guidance more prominent and new simple introduction to inventories introduced • Managed land a proxy for anthropogenic • Actual annual estimates • Direct emissions estimation introduced • Relationship between carbon pools clarified • Consistent approach to indirect N, not just agricultural sources • Could be relevant at project level

  8. Policy Relevance • 2006 Guidelines are IPCC’s best, most internally consistent assessment of inventory science • They are an evolutionary development from the 96 Guidelines plus GPG and (personal view) could be used in a manner consistent with the existing Guidance • Timing of adoption clearly a matter for Parties
