National Inventory for Austria

This report presents emission trends in Austrian agriculture, focusing on GHG emissions in 2000/2001 and uncertainties in data. Key sources like enteric fermentation and agricultural soils are analyzed, with comparisons between 1990-2000 trends. The report delves into activity data, emission factors for CH4 and N2O, and methodological issues affecting inventory quality. It suggests improvements such as differentiation in milk production systems, organic rations for livestock, and methodologies for estimating methane emissions and feed intake levels. Future enhancements could include updating emission factors, manure management systems, and NH3 emissions in housing/storage. Detailed and valuable insights are provided for policymakers and researchers in the agriculture sector.

  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)
