About this data

The data is supplied by the EUROCONTROL Aviation Sustainability Unit .

The CO 2 emissions were calculated with the EUROCONTROL Small Emitters Tool (SET) , which enables to estimate the fuel burn and associated CO 2 emissions for an entire flight. Hence, the results reflect total CO 2 emissions from controlled flights rather than ANSP/ATM performance.

The total CO 2 emissions for each State were calculated based on departing IFR flights billed by the EUROCONTROL Route Charges Office , aircraft type and actual flown distance (full trajectory from origin to destination).

For instance, the total CO 2 emissions for the full trajectory of a flight from Brussels to New York would be included in the results for Belgium. A flight from New York to Brussels would however NOT be included in the results for Belgium.
