AARHUS UNIVERSITY NMVOC emission from animal husbandry and manure management  Part of Guidebook update contract  Currently no NMVOC emission factors  Insufficient data  Measurements made in USA  Significant emissions, especially from silage  Could double some national emissions  Compounds emitted may have limited impact on air quality  Work ongoing

AARHUS UNIVERSITY Emissions from biogas production  Guidance related to N (ammonia, nitric oxide) will be uploaded to TFEIP website.  How to partition emissions between NFR codes  NMVOC from silage used for biogas production  Energy crops  Why should agriculture get the blame?

AARHUS UNIVERSITY PAH emissions from field burning  Current Guidebook section  EF for specific PAHs in Convention not included  Bulk emission factor is incorrect  Specify EFs for specified PAHs  Tier 2 – crop specific  Tier 1 – mean of most common crops 4

AARHUS UNIVERSITY All emissions from field burning  Part of Guidebook update contract  Consistency of emission factors  Black carbon  Work ongoing  (Note also work on Small scale burning of wastes) 5

AARHUS UNIVERSITY Ammonia emissions from fertilisers  Part of Guidebook update contract  Improve methodology  Collate recent data  Update emission factors  Work ongoing 6

AARHUS UNIVERSITY Other matters  Swiss ammonia emission model  Detailed survey data  Detailed, farm-scale modelling  Task Force on Reactive Nitrogen  Joint meeting of Agriculture and Nature Panel/Expert Panel on Mitigation of Agricultural Nitrogen  Friday 28 Sept, Berlin  Coordination between Tier 2 and Tier 3 (mitigation measures) 7

AARHUS UNIVERSITY Workplan  Continue participation in updating the selected Guidebook chapters  Joint meeting between Panel and EPMAN (TFRN)  Review need for new NFR code(s)  Revisit ammonia emissions from crops 8
