Collaboration Ag & Nature/EPMAN Nick Hutchings, Barbara Amon and Rainer Steinbrecher
Collaboration – on what? • Identification of new emitting activities • ! Revised/updated emission factors • ! Developments in inventory methodologies • New/additional sources of activity data • ! Quality control criteria for emission inventories • ! Quality criteria for Cat I, II and III measures • Need for new research
Collaboration – how? • Joint meetings • Ag and Nature Panel sessions • Collaboration on documentation
Example – quality control of NH3 emission inventories • Emission = activity * emission factor • Tier 2 ammonia • N flow, organic and TAN • Separate treatment of livestock categories • Separate treatment of solid and liquid • Mitigation measures • Tier 3
Example – quality control of NH3 emission inventories • Criteria for documentation of emission factors • EPMAN guidance • Indicative abatement efficiencies • Need for country-specific data? • Link Emission Inventory Guidebook and EPMAN guidance documents? • Model documentation, sources of activity data
