2006 IPCC Guidelines - Overview

Overview of the 2006 IPCC Guidelines initiated from OECD in 1992, focusing on rationalizing structure, promoting consistency, and enhancing efficiency in estimating greenhouse gas emissions for various sectors. The guidelines have been widely adopted and offer improved coverage and policy relevance in inventory science.

  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
