  1. National Inventory for Austria Presented by: Alfred PöllingerFederal Research Institute for Agriculture in Alpine RegionsBAL GumpensteinA-8952 Irdning

  2. Made by: • Univeristy for Agriculture, ViennaInstitute of Agricultrual, Environmental and Energy EngineeringDr. Barbara Amon • Federal Environment Agency, ViennaDr. Klaus Radunsky and D.I. Manfred Ritter

  3. Content • Emission Trend - Agriculture • GHG emissions from Agriculture in the year 2000 / 2001 and changes • Uncertainty Assessment • Well known activity datas for the Austrian Inventory • Possibilities for future improvement of inventory quality

  4. Emission Trends - Agriculture • In the year 2000 – 6 % contribution to the total of Austria‘s GHG emissions • Trend 1990 – 2000: decrease of 14 %CH4 – 16 %N2O – 3,6 % • Key sources:Enteric fermentation (54%) Agricultural soils (35%)Manure management (10%) • Since 1990 field burning is legally restricted

  5. Reference: National Inventroy Report 2002 GHG emissions from Agriculture in the year 2000

  6. Reference: National Inventroy Report 2003 GHG emissions from Agriculture in the year 2001

  7. Uncertainty Assessment • Activity data: animal population – 10 % agricultural use land – 5 % • CH4-Emission factor: Enteric Fermentation – 50 % Agricultural Soils – 100 % • N2O-Emission factor: Agricultural Soils – >143 %Reference: WINIWARTER & RYPDAL, 2001

  8. Changes in prepairing InventoryCompaired 2002 to 2003 Report • 4A Enteric Fermentation- CH4: CORINAIR – IPCC Tier 2 m. Uncertainty +/– 8% • 4B Manure Management- N2O: Not reported 2002 Uncertainty –50% to +100%- CH4: Tier 2 methology Uncertainty +/– 90% • 4D Agricultural soils- N2O: Tier 1 methology + expert judgement Uncertainty +/– 24%

  9. Methodological Issues NE = Not estimated

  10. Well known activity datas for the Austrian Inventory • Animal population data (Statistik Austria -www.oestat.gv.at) • Average annual milk production of dairy cows • Animal lifeweight • Climate • Rations of Austrian cattle are known • N excretion

  11. Possibilities for future -improvement of inventory quality • Milk production – differentiation between milk production from conventional and organic systems • Ration: Organic rations for dairy cattle Rations for fattening pigs and sows • It might be useful to develop a methodology that estimates methane emissions from net energy intake • Update of the feed intake levels – VS excretion • Bo values – IPCC default values are used

  12. Possibilities for future -improvement of inventory quality • MCF values – field conditions • Manure management systems • N excretion – differentiation between organic and conventional systems • N2O emission factors • TAN content – update every 5 years • NH3 emissions from housing and storage(Austrian loose housing, slooped floor systems for fattening pigs, storage systems)
