EUROCONTROL has developed an aviation fuel use and emission inventory system (FEIS) that covers all 44 member countries of the European Civil Aviation Conference (ECAC) from the year 2005. We update FEIS every year.
The FEIS uses EUROCONTROL's Advanced Emission Model (AEM) to process 4D flight trajectory data, flight segment by flight segment, and estimates the fuel consumption and the masses of a long list of emissions produced in each segment. These are then aggregated to give the fuel burn and emissions per flight. This is carried out for all flight data collected by EUROCONTROL.
