1. National System Emissions 1 Robert Kludt, FG Emissions situation, workshop Copenhagen 17.-18. May 2004 German Emissions Inventory: GHG from aviation and navigation presentation: Robert Kludt

2. National System Emissions 2 Robert Kludt, FG Emissions situation, workshop Copenhagen 17.-18. May 2004 German Emissions Reporting Responsible National Focal Point: Germany‘s Federal Environmental Agency Data central data base: Zentrales System Emissionen (ZSE) several reporting obligations: UNFCCC, UN-ECE, various queries

3. National System Emissions 3 Robert Kludt, FG Emissions situation, workshop Copenhagen 17.-18. May 2004 German Emissions Reporting: calculation of domestic and international aviation and navigation For details and background information see also the Annex III of workshop preperation and forthcoming NIR 2004 Most methodological problems in calculation of emissions from aviation: extensive flight data, but not detailed available

4. National System Emissions 4 Robert Kludt, FG Emissions situation, workshop Copenhagen 17.-18. May 2004 German Emissions Reporting: calculation of domestic and international aviation and navigation Tier 1 calculation: emissions are calculated from total fuel consumption Basic data source: total fuel sales bunker fuel data: all German fuel sales data supplied by AGEB

5. National System Emissions 5 Robert Kludt, FG Emissions situation, workshop Copenhagen 17.-18. May 2004 German Emissions Reporting: calculation of domestic and international aviation and navigation differentiation between domestic and international: maritime – differentiated fuel sales (tax system) air - expert judgement on a 20:80 split between domestic and international EF sources: CO2: stoichiometric 3.150 g/kg kerosene other pollutants: expert judgement based on research publications

6. National System Emissions 6 Robert Kludt, FG Emissions situation, workshop Copenhagen 17.-18. May 2004 German Emissions Reporting: validation of separating method of aviation domestic: number of passengers with domestic destination and passengers changed international: difference between total passengers and domestic Data source: research project by UBA (UBA-Texte 17/01)

7. National System Emissions 7 Robert Kludt, FG Emissions situation, workshop Copenhagen 17.-18. May 2004 German Emissions Reporting: calculation of domestic and international aviations emissions How could EU level data sources be used in the inventory preparation? EUROCONTROL data could be used for Tier 2 calculation. We need activity data and emissions from EUROCONTROL.

8. National System Emissions 8 Robert Kludt, FG Emissions situation, workshop Copenhagen 17.-18. May 2004 Outlook Methodological discussion is ongoing in the course of the National System with outlook for research projects. Aviation: focus on EUROCONTROL data QA/QC system under development

9. National System Emissions 9 Robert Kludt, FG Emissions situation, workshop Copenhagen 17.-18. May 2004 German Emission Factor Database (GEREF) http://geref.uba.de further with button „GEREF english version“ access to data of the German emission reporting Emission factors can be used for comparisons and examinations. Website is still in development.
