2006 IPCC Guidelines - Overview

• Jim Penman
• Steering Group Member (UK Defra)

2
Origins

• OECD initiation (1992) gt 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.

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)

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

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 IPCCs 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
