Analysis of European greenhouse gas inventories in the aviation sector

ETC/ACC Technical Paper 2007/6

Greenhouse gas emissions from aviation are part of the reporting obligations of Parties to the UNFCCC and the Kyoto Protocol. Only emissions from domestic aviation are part of the national emission reduction obligations and have to be reported separately from emissions caused by international aviation. While data on total fuel consumption by aviation is normally available the split between domestic and international aviation requires information which is not always available. This paper compares estimates for greenhouse gas emissions from aviation as reported by EEA Member States with estimates calculated by the European Organisation for the Safety of Air Navigation (Eurocontrol). Eurocontrol calculations are based on flight movement data only and provide an estimate for fuel burn and GHG emissions which is independent of the estimates produces by the Member States. This analysis is part of the quality assurance and quality control programme for the greenhouse gas inventory of the European Community and might help countries and the EC in improving their estimates.
