1. Chapter 4: Supplementary Methods and GPG Arising from the Kyoto Protocol (Sections 4.1 & 4.2) CLA: Bernhard Schlamadinger (Austria), Henry Janzen (Canada), Werner Kurz (Canada), Rodel Lasco (Philippines), Kansri Boonpragob (Thailand), and Pete Smith (UK) LA : Pascale Collas (Canada), El Nur Abdalla El Siddig (Sudan), Andreas Fischlin (Switzerland), Mitsuo Matsumoto (Japan), Alexander Nakhutin (Russia), Ian Noble (Australia), Gerome Pignard (France), Zoltan Somogyi (Hungary), and Xiao-Quan Zhang (China) CA: Mark Easter (USA), Genevieve Patenaude (Canada), Keith Paustian (USA, and Yoshiki Yamagata (Japan) Presented by: Pete Smith, University of Aberdeen, Scotland, UK

2. Objective  To describe the information requirements, methods and good practice guidance for the reporting of CO 2 and non-CO 2 emissions by sources and removals by sinks as required by the Kyoto Protocol (Articles 3.3, 3.4, 6 and 12) that are supplementary to those for National Greenhouse Gas Inventories.

3. General approach  Identify lands (definitional and temporal constraints) - eligible after human actions; provide supplementary methods to chapter 2  Establish estimate of C stock changes and non-CO 2 GHG emissions on these lands; provide supplementary methods to chapter 3

4. Table of Contents 4.1 General overview  4.1.1 Roadmap to estimating and reporting supplementary information for activities under articles 3.3, 3.4, 6 and 12  4.1.2 General rules for categorisation of land areas under articles 3.3 and 3.4  4.1.3 Relationship between annex I parties ’ national inventories and article 6 projects 4.2 Methods for estimation, measurement, monitoring and reporting of LULUCF activities under articles 3.3 and 3.4  4.2.1 Relationship between UNFCCC land categories and Kyoto Protocol (articles 3.3 and 3.4) land categories  4.2.2 Generic methodologies for area identification, stratification and reporting  4.2.3 Generic methodological issues for estimating C stock change and greenhouse gas emissions  4.2.4 Other generic methodological issues  4.2.5 Afforestation and reforestation  4.2.6 Deforestation  4.2.7 Forest management  4.2.8 Cropland management  4.2.9 Grazing land management  4.2.10 Revegetation

5. 4.1.1. Roadmap  STEP 1. Defining “ forest ”, application of definitions to national circumstances, establishing a hierarchy among selected Article 3.4 activities  STEP 2. Identify lands subject to activities under Article 3.3 and any elected activities under Article 3.4  STEP 3. Estimate carbon stock changes and non-CO 2 greenhouse gas emissions on the lands identified under Step 2 above  STEP 4. Identify areas and estimate carbon stock changes and non-CO 2 greenhouse gas emissions in Article 12 projects.

6. Demonstration of classification of a unit of land under Article 3.3 (ARD) or land under Article 3.4 (FM, CM, GM and RV) as of year X of the Commitment Period (2008, 2009…2012)

7. Relationship between Article 3.3 and 3.4 activities and basic land-use categories

8. Land Classification in the national inventories under the UNFCCC of a Hypothetical Country in Year X of the Commitment Period

9. Land classification for Kyoto Protocol reporting for a hypothetical country in year X of the commitment period.

10. Two Reporting Methods for Land Subject to Articles 3.3 and 3.4 Activities

11. Relationship between Approaches in Chapter 2 and Reporting methods in Chapter 4. (statistical only) (land-use transitions) (full tracking of all land)

12. Decision Tree for Choosing Reporting Method for Land Subject to Activities under Articles 3.3 and 3.4

13. Common subsections for AR, D, FM, CM, GM and RV  Definitional and Methodological issues  1990 BASE YEAR (CM, GM, RV)  Choice of methods for identifying lands  Choice of methods for estimating C stock changes Choice of activity data and emission factors Completeness Developing a consistent time series Reporting and documentation QA/QC  For CM, GM & RV – the following sections Mineral soils CO 2 emissions/removals from organic soils CO 2 emissions from liming  Choice of methods for estimating non-CO 2 emissions

14. Decision tree to determine whether a land qualifies as forest management

15. Decision tree to select the tier for estimating for carbon emissions/removals from mineral soils under the Kyoto Protocol

16. Summary table of greenhouse gas emissions by sources and removals by sinks by articles 3.3 and 3.4 activities for the inventory year y Reporting is annual but measurements might be less frequent

17. Status  Meeting in KL - mainly to deal with comments from first government review  Focus in KL was on addressing comments, rationalisation and some major restructuring  Translation of statement of the scientific problem to practical GPG  Draft for Second Review submitted
