9. Calculation Methods-Summary Both national data and IPCC default values used for calculating the parameters

10. CH4 From Enteric Fermentation Cattle: IPCC Tier 2 method with both national data and IPCC default values used for calculating emission factors Other livestock: IPCC Tier 1 method with IPCC default values as emission factors except for reindeer (national EF)

11. CH4 From Enteric Fermentation-Methods and Emission Factors

12. CH4 From Manure Management Calculated for each animal type and manure management system by IPCC Tier 2 method with both national data and IPCC default values for parameters

13. CH4 From Manure Management- Emission Factors

14. N2O From Manure Management Calculated by using IPCC method and IPCC default emission factors for each manure management system

15. N2O From Manure Management- Emission Factors

16. N2O Emissions From Soils Calculated by using IPCC Tier 1 a method for direct emissions and IPCC Tier 1 b method for indirect emissions

17. N2O Emissions From Soils

18. Direct N2O Emissions From Soils

19. Indirect N2O Emissions From Soils

20. CO2 Emissions From Soils • Mineral soils: Calculated by using changes in carbon stocksin 20 years period resulting from land-use changes • Organic soils: Calculated by using both IPCC and national emission factors • Liming: Calculated by using IPCC method and both IPCC and national conversion factors

21. Mineral Soils-Parameters • Land-use type: long term cultivated, improved pasture, set aside, forested, abandoned • Soil type (area of total): high activity (11%), low activity (41 %), sandy (33%) • Soil carbon stock (Mg/ha): sandy 14-22, low activity and high activity 56-88

22. Organic Soils-Emission factors

23. Liming • IPCC method and both IPCC and national conversion factors used • Conversion factors: limestone 0.12, dolomite 0.13, briquette lime 0.12 • Amounts of lime from the Finnish Liming Association

25. Quality Assurance and Control In co-operation with: Statistics Finland Finnish Environment Institute and Technical Research Centre of Finland Principal tasks at the moment: Complete documentation of the system Updating the parameters used

26. Future Development • Parameter updating • QA/QC measures • Uncertainty analysis • Measurements for acquiring national data • Development of new calculation methods • International co-operation
