GHGMM Workshop Emissions of Greenhouse Gases from Aviation and Navigation EEA, Copenhagen MAY 2004 Agenda item 10 Comparison of “Eurocontrol” and IEA data with MS inventories
1.TRENDS in brief Indicators, not inventories Road, rail, inland waterways, maritime and aviation Energy, emissions, noise (road, rail, aviation), waste (road) Projections to 2020
2.TRENDS – Aviation Single data source (Eurocontrol) Single methodology Multiple uses (flexible outputs)
3.Relevance to Inventories Detailed air traffic data are available Very detailed method is feasible Domestic and international energy consumption can be split
4.Discrepancies
4a.Why the discrepancies? Fuel reserves are carried Aircraft do not refuel at every LTO Inclusion/non-inclusion of overseas territories Inaccurate coefficients for some (older) aircraft types Ground operations
5.Particular difficulties Size of dataset Separation between passengers and freight Overseas territories Allocation Pre-1996 data Military and VFR flights
