NMVOC emission from animal husbandry and manure managementPart of Guidebook update contractCurrently no NMVOC emission factors

Insufficient data

Measurements made in USASignificant emissions, especially from silage

Could double some national emissionsCompounds emitted may have limited impact on air

Emissions from biogas production

Guidance related to N (ammonia, nitric oxide) will be uploaded to TFEIP website.

How to partition emissions between NFR codesNMVOC from silage used for biogas production

Energy cropsWhy should agriculture get the blame?

AARHUSUNIVERSITY

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
