4. National procedures Method: According to CORINAIR „best practice“
KALIVODA M., KUDRNA M.: Report on Air Traffic Emission Calculation in Austria 1990 – 2000
Calibration by fuel sold
Extrapolation for the years 2001 and (by fuel used and movements)
Simple/very simple methodology for CH4 and N2O

ATC-Data of Austrocontrol for 1995, 1998 and 2000
Fuel Consumption:
Fachverband der Mineralölindustrie
Statistic Austria (Energy Statistic)

6. Calibration by fuel Difference fuel calculatded – sold:
kerosene price
Mixed calc. UNECE
For each airport
Different quality of data
Therefore different methods (simple/detailed)

7. Example CO2

8. domestic - international
Domestic: between Austrian airports
International: abroad <> Austria
Seperation by movement-data of Austro Control
Fuel data: no differentiation

9. Lessons learnded Difference between methodologies up to 700% (LTO)
Problems with source-data:
No consistency between the data sets (fuel, movements)
Different grade of quality of data from airports
Improvement of data needed:
Numbers of flights per destination and Aircraft

10. Outlook
Retain a detailed level
Update within the next years
