Essential for emissions reporting is the separation of domestic and international air traffic. This happens using a so-called split factor representing the ratio of fuel consumption for national flights and the over-all consumption. | Essential for emissions reporting is the separation of domestic and international air traffic.

- | For determination of this ratio, results from TREMOD AV (TRansport Emissions MODel AViation) have been used, based on the great circle distances flown by the different types of aircraft (Knörr et al. (2020c) [(KNOERR2020c)] & Gores (2020) [(GORES2020)].
