National Emission Inventories nGreenhouse Gas Inventories UN Framework Convention on Climate Change and Kyoto Protocol EU Monitoring Mechanism Decision (280/2004/EC) nAir Pollutant Inventories UNECE Convention on Long Range Transboundary Air Pollution (CLRTAP) and its 8 Protocols National Emission Ceilings Directive (2001/81/EC) Large Combustion Plant Directive (2001/80/EC)

What do we report? nGreenhouse Gas Inventories Inventories on CO 2, CH 4, N 2 O, HFCs, PFCs and SF 6 annually (15 th Jan to EU and 15 th April UNFCCC) National Inventory Report (UNFCCC 15 th April) nAir Pollutant Inventories (15 th February annually CLRTAP) Main pollutants; NO x, SO 2, NMVOC, NH 3 and CO Particulate matter; TSP, PM 10 and PM 2.5 Heavy metals; Pb, Cd, Hg (priority) As, Cr, Cu, Ni, Se and Zn (additional) Persistent Organic Pollutants; Dioxins (PCDD/PCDF), PAHs, HCB (mandatory) PCBs (voluntary) National data gridded every 5 th year (EMEP 50km x 50km) Informative Inventory Report (15 th March annually)

What do we report? (contd) nLarge Combustion Plant Directive (LCPD) Inventories on NO x, SO 2 and Dust annually (30 th Sept) nNational Emission Ceilings Directive (NECD) NO x, SO 2, NMVOC and NH 3 annually (31 st Dec) nNational Emission Projections – Future emission trends nCLRTAP, NEC and GHG to 2020/2030 nFAPRI – animal numbers, crop statistics

Agricultural Emission Inventories nGHG nCO 2 e ~ 32% of national total nAgricultural CH 4 ~ 91% of national CH 4 nAgricultural N 2 O ~ 92% of national N 2 O nAir Pollutant nNH 3 ~ 98% of total

Agricultural Emission Inventories nGHG nEnteric fermentation – CH 4 nManure management – CH 4 & N 2 O nAgricultural soils (direct and indirect) – N 2 O nNH 3 nManure management nFertilizer

Other statistics of interest nDED analysis for gridded data nEvery five years CLRTAP, 10 km x 10 km nFarm Structures Survey nManure Management Practices

Conclusions nAgricultural statistics are v. important part of national GHG and air pollutant inventories nAgri- environmental data nFarm Structure survey nQuestions
