Context for IPCC 2006 Guidelines

Jim Penman Steering Group Member (UK Defra)

Origins

 OECD initiation produced IPPC guidelines in 1995, 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.

Structure of 2006 Guidelines

Aims:  Reduce 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 land use  Vol 5 - Waste

Consistency amongst sectors

 Combination of LULUF and Agriculture – common land use statistics, treatment of N inputs  Better coordination between Energy and IPPU on feedstocks  …and between energy and AFOLU on biofuels emissions  …and between energy and waste on incineration and waste derived fuels  …and between waste and HWP.

Other improvements

 HWP, wetlands advice integrated  Consistent approach to indirect N  Full carbon basis for fossil fuel emissions throughout  Relationship between carbon pools clarified  EFDB linkage  General guidance more prominent

Data Collection

 Inclusion of cross cutting guidance a major advance of GPG  Data representitiveness key issue – 2006 GL extends significantly (sources of data, data collection, sensor placement etc)  Particularly relevant because of introduction GHG emissions trading

Significance of Inventory Guidelines

 As with GPG basic principle for 2006 GL remains

neither under nor overestimates so far as can be judged

 IPCC very pleased that the 1996 Guidelines and GPG have proved of such use to Parties in providing unbiased estimates and believes the 2006 Guidelines will do so in future.
