  1. Update on issues related to the IPCC 2006 Guidelines Simon Eggleston IPCC Task Force on National Greenhouse Gas Inventories

  2. Introduction • Guidelines have evolved from 1996 to 2006 • Major step was the Good Practice Guidance (GPG) • Complete, consistent, comparable, transparent, and accurate inventories taking account of available resources • Major change was from 1996 LUCF to GPG LULUCF • 2006 Guidelines [2.5 years work, 250 authors] • 4 categories (Energy, IPPU, AFOLU & Waste) • Require similar resources to implement as the 1996 Guidelines plus the two volumes of GPG • Does not pre-empt accounting choices – methods generate all information needed • The best globally applicable methods

  3. 2006 Guidelines • Update and expand earlier guidelines • While remaining consistentancy with earlier guidelines • Have a general introduction to inventory compilation • Include a new chapter on data collection • Include updated default values and methods • Restructure main categories and sub-sectors to clarify and simplify inventories and to reduce chance of double-counting • Include methods for sectors previously included in other sectors or under “other” • Include additional direct greenhouse gases for which estimation methods are provided

  4. Tiers and Key Categories Many defaults updated in 2006 Guidelines

  5. “New” gases in 2006 Guidelines (IPPU)– Methodologies in 2006 Guidelines By-product & fugitive emissions Only Gases with methods available included in 2006 Guidelines

  6. Direct CO2 & Indirect N2O 2006 Guidelines give methods to calculate this 2006 Guidelines “CO2 Emissions” do not include this 2006 Guidelines “CO2 Emissions” 2006 Guidelines includes ALL NH3 & NOx Emissions

  7. Estimation of Actual Annual Emissions (Fluorinated compounds, Landfills) • For a few sources in the 1996 Guidelines & GPG, the simplest methodology estimates a “potential emission” (current and future emissions) rather than the actual annual emission. • In the 2006 Guidelines, simple default methods estimate actual annual emissions in the year they occur, thus removing the need for potential emissions. • This allows: • the emission reductions of abatement techniques to be estimated • ensures that the methods are compatible with higher tier methods.

  8. Additional Guidance in 2006 Guidelines

  9. Structure of the AFOLU Sector AFOLU AFOLU

  10. Improvements in AFOLU Guidance • Wetlands • 2006 GL has complete coverage of peat lands • 2006 GL improved coverage of flooded lands but some guidance is incomplete and awaits further scientific investigation • Fires • Guidelines have increased consistency and coverage of fires • All emissions from fires reported in a separate category for increased transparency • Managed land is used in these guidelines as a proxy for identifying anthropogenic emissions by sources and removals by sinks. • use of managed land as a proxy for anthropogenic effects was introduced in the GPG-LULUCF and is consistent with the Revised 1996 Guidelines. • Managed land is land where human interventions and practices have been applied to perform production, ecological or social functions

  11. Subsequent IPCC Work • Helsinki 2008. (LULUCF/AFOLU Guidance) • Concluded that additional assistance on activity data would assist LULUCF/AFOLU compilers rather than methodological work • Also needed: Consideration of Uncertainties and Tier 3 models, and improvement of EFDB • Brazil 2009 (Managed Land) • No current alternative to the use of “managed land” as a proxy for identifying anthropogenic emissions was identified • Possible alternatives need further scientific development and subsequent assessment

  12. Summary • 2006 Guidelines • Maintain the same basic methodological approaches from 1996 Guidelines, GPG 2000 & GPG LULUCF • Improved and updated default values • Only actual emissions – potential estimates not needed • Methods give direct CO2 emissions • More default methods and direct Greenhouse Gases • Categories simplified and clarified with IPPU and AFOLU • Do not pre-empt accounting choices as all information is retained • Can map back to 1996 GL plus GPG
