The 2006 IPCC Guidelines

1. The 2006 IPCC Guidelines Simon Eggleston Head, Technical Support Unit for the IPCC National Greenhouse Gas Inventories Programme

2. Note: • Production of new guidelines is still at an early stage (due 2006) • Guidelines still need to be compiled and reviewed • So cannot state definitively contents of new guidelines • Can indicate areas where changes or additions are anticipated • We will introduce issues that have arisen while drafting the volumes

3. The Existing IPCC Guidelines • Comprise three parts: • Revised 1996 IPCC Guidelines For National Greenhouse Gas Inventories • Good Practice Guidance and Uncertainty Management in National Greenhouse Gas Inventories (GPG 2000) • Good Practice Guidance for Land Use, Land-Use Change and Forestry (GPG2003)

4. Guidelines have been very successful. • The approach provides options for all countries. • There are methods for almost all source and sink categories. • The IPCC created standardized reporting tables • Successfully standardized source sink category definitions, units, classifications, and reporting techniques • Have become the standard reference for inventories • Have played a critical role in furthering the goals of the UNFCCC.

5. IPCC Good Practice Guidance • Framework for prioritizing resources through guidance on methodological choice and key category analysis • Guidance on QA/QC, quantitative uncertainty analysis, methodological choice, reporting and documentation, time series and consistency • LULUCF change from activity-based to land use-based accounting system • New guidance on land classification, Kyoto accounting, additional categories • New reporting structure and tables

6. However • Basis of Guidelines now 10 years old • New information, scientific and technical advances have appeared • Further sources have been identified or have arisen • Time for a complete revision of the guidelines

7. Mandate • SBSTA17 invited the IPCC to revise the Revised 1996 IPCC Guidelines for National Greenhouse Gas Inventories, taking into consideration the relevant work under the Convention and the Kyoto Protocol, and to aim to complete the work by early 2006. • In response to the SBSTA request, IPCC agreed the terms of reference and outline of the work at IPCC XXI in late 2003.

8. 2006 Guidelines • Will be based on • the existing Guidelines and Good Practice Guidance reports • Emission Factor Database (EFDB) • Advances in science and technology • The experience in the use of GLs/GPGs as well as experience from UNFCCC inventory reviews (e.g.FCCC/SBSTA/2003/INF.10) • A key principle will be to approach the revision with flexibility but to maintain the existing structure as much as possible to facilitate the job of inventory preparers (evolution not revolution)

9. 2006 Guidelines – 5 Volumes Contents: Overview • Cross-cutting Issues, and Reporting Tables • Energy • Industrial Processes and Product Use (IPPU) • Agriculture, Forestry and Other Land Use (AFOLU) • Waste

10. Volume 1: Cross-cutting topics • Revised and consistent general guidance on • QA/QC, • Quantitative uncertainty analysis, • Methodological choice, • Data selection, • Reporting and documentation, • Time series and consistency • NEW recommendation for key category analysis level of assessment

11. Volume 2: Energy • Methods for most sources are well developed from the 1996 Guidelines and Good Practice • Some important issues: • Treatment of energy use of fossil fuel, • Accounting for atmospheric oxidation of CH4, NMVOCs, and CO (e.g., fugitive CH4 from coal mining, oil & gas) • Capture and storage of CO2 • Abandoned coal mines • Aviation and marine emissions

12. Volume 3: IPPU • Merging of Industrial Processes and Solvents chapters from the 1996 Guidelines • Significant development on F-gases • Areas for new work: • Flat-panel display • Broader coverage of mineral and chemical industry

13. Volume 4: AFOLU • New structure merges Agriculture and LUCF to resolve inconsistencies and avoid double counting/omissions. • Builds on the work of GPG 2000 and GPG 2003, particularly the shift to consistent land classification approach • Countries have had very little experience with LUCF GPG • General need to streamline the guidance in LUCF GPG

14. Volume 5: Waste • No major restructuring necessary • Areas for further development/new methods: • Improvement of emission factors for developing countries • Methodological work on accounting for reductions in CH4 from landfills • Development of improved Default method for Landfill sites

15. 2006 Guidelines - Gases Current coverage: CO2, CH4, N2O, HFCs, PFCs and SF6 (direct GHGs) NOx, CO and NMVOC and SO2 (indirect GHG; precursors) New gases identified in the IPCC TAR will be included if they meet following criteria: • GWP Available • Anthropogenic sources identified • Basis for methodological development • Relative importance total emissions

16. Precursors & Indirect GHG • NOx, CO and NMVOC and SO2 • A need for development for New methods for ozone precursors is not anticipated as these are addressed under other agreements and conventions. • Users referred to other guidance

17. 2006 Guidelines – New Sources • New Sources will be included if the following criteria are met: • Basis for methodological development including the ability to develop default emission factors exists • It is feasible to obtain the necessary data to implement the method • The source is significant within the sector.

19. Conclusions • Writing is still continuing - First Order Draft nearly finished – due January 2005 • Review not undertaken yet - So cannot be definitive on any changes in guidelines • However many improvements identified • Guidelines to target for delivery in 2006
