1. Agriculture & Nature Panel Nick Hutchings Barbara Amon Rainer Steinbrecher

2. Agenda  Guidebook revision  Maintenance and Improvement Plan for Guidebook  Report from Task Force on Reactive Nitrogen

3. Guidebook revision  NMVOC emissions from Animal Husbandry and Manure Management (4B)

4. NMVOC emissions in 4B  No emission factor in the current Guidebook  New emission factor in revised Guidebook  For some Parties, 4B would become the major source  Reasoned criticism at previous TFEIP meeting  Re-assess the evidence underpining emission factor

5. 4B NMVOCs conclusions  Emission factor in revised Guidebook unreliable  Requires more detailed review

6. NMVOC – proposed action  Revert to position in current Guidebook  No emission factor for 4B – leave placeholders  Include review in Maintenance Plan  Timescale  Work ongoing in Europe and USA  US-EPA plan to establish emission factors in 2011  Propose to undertake review in 2010  Funding  60 days

7. EFDB  Just Guidebook emission factors (linked to Guidebook)  Just Guidebook emission factors (unlinked)  Guidebook and national emission factors (unlinked)  Guidebook and submitted emission factors (unlinked)

8. Just Guidebook (linked)  Create additional work  Database – Excel – Word  Need to restructure database when amending methodologies  Limited resources  Would divert resources from Guidebook maintenance and improvement  Not convinced of substantial (non- Guidebook) benefits

9. Other options  Just Guidebook emission factors (unlinked)  OK  Guidebook and national emission factors (unlinked)  OK – if IIRs available as documentation  Guidebook and submitted emission factors (unlinked)  Quality control issues or resource issues

10. Revision process in the future  Rolling revision of chapters  Depends on scientific/technological developments  All chapters should be revised regularly

11. Chapters recommended for endorsement  Nature  11B Forest fires  B1109 Gas seeps

12. Natural sources Natural Sources to be considered: SourcesPollutants Vegetation, esp. ForestsNMVOC Biomass burning and forest fires (new)NO x, PM, CO, CO 2, CH 4, OC, EC, VOC NO from soilsNO Pollen (New)PM Wild animalsCH 4, NH 3 Anoxic soil processes (wetlands)CH 4 Natural seepage of gas storageCH 4, NMVOC Wind blown dust (incl. Saharan) (new)PM VolcanoesSO x, NO x, PM, HF, HCl, CO 2, HNO 3 LightningNO x Sea, Coastal zones (New)PM, DMS

13. Specific items for the Maintenance Plan  Review of NMVOC emissions in 4B  Review of ammonia emission from fertilisers  VOC emissions from vegetation  Methodology for ammonia emissions from biogas facilities  Ammonia emission from crops

14. Priorities and resources  Review of NMVOC emissions in 4B  Priority 1  60 days  Review of ammonia emission from fertilisers  Priority 2  25 days

15. Priorities and resources  VOC emissions from vegetation  Priority 2  0 days  Methodology for ammonia emissions from biogas facilities  Priority 3  2-10 days  Ammonia emission from crops  Priority 3

16. Any other business  Potential versus net emissions  PM and NMVOCs  Make clear in Guidebook  Who should calculate net emissions?  Reporting of ammonia in 4B contra 4D
