The calculator contains flights operated by Air France, KLM, their regional partners (BritAir, Cityjet, Régional, Airlinair, CCM Airlines or KLM CityHopper) or Transavia.com France.
Calculation methodology for Air France and its regional partners flights :
CO2 emissions are directly proportional to the quantity of fuel consumed (3.15 tons of CO2 produced by the combustion of 1 Ton of kerosene).
The calculation is based on the actual operating data recorded on each flight of last calendar year:
-
the type(s) of aircraft operated on the route,
-
the actual fuel consumption on each route,
-
the number of passengers carried on each route,
-
the weight of baggage and goods carried on each route.
To affect to passenger and freight the exact CO2 emissions they are accountable for, two calculations are performed:
-
Most of our aircraft carry both passengers and freight. The quantity of fuel is divided between passengers and freight according to their respective weight (cabin equipment included)
-
Several aircraft can be used on the same O&D. The fuel consumption on an O&D os calculated by averaging all fuel consumption on the line during the year, all type of aircraft included.
For new destinations on which we have no real registered data, the amount of CO2 was calculated on the basis of the distance to destination, the average consumption of the aircraft type assigned to the flight and the average load factor on the network.

The current calculator will be updated in order to take into account :
-
remarks and suggestions that you are welcome to send to mail.developpementdurable@airfrance.fr,
-
changes to our operations. The databases (aircraft types, fuel consumptions, passengers transported, …) will be regularly updated with real operational data.
