The EMEP/EEA air pollutant emission inventory guidebook (formerly referred to as the EMEP CORINAIR emission inventory guidebook) provides guidance on estimating emissions from both anthropogenic and natural emission sources. It is designed to facilitate reporting of emission inventories by countries to the UNECE Convention on Long-range Transboundary Air Pollution and the EU National Emission Ceilings Directive. The EEA publishes the Guidebook, with the UNECE’s Task Force on Emission Inventories and Projections having responsibility for the technical content of the chapters.
The EMEP/EEA aviation methodology
The guidebook provides detailed fuel consumption data for over 140 specific jet, turboprop and military aircraft types, and represents the foremost methodology for calculation aviation-associated greenhouse gas emissions.
Aircraft fuel consumption dynamics are differentiated by into associated with landing and take off (LTO) phases (taxiing, take off, climb out, landing) and cruising at altitude. This fuel consumption is converted into CO2 emissions by using a CO2 emissions factor of 3.15 (kg CO2 per kg fuel). This value corresponds to the CO2 emissions factor for 'jet fuel' specified by the IPCC (1999).
