This endpoint returns CO2e emissions (i.e CO2 equivalent emissions) for a direct flight between a source airport and a target airport.

You can either pass an aircraft IATA code to get the CO2 emissions of this specific aircraft or only the aircraft type. In case the IATA code is given, the emissions are calculated using EEA/EMEP methodology and EUROCONTROL data. They take into account take-off, landing, climbing, descent and cruising phases. In case the aircraft IATA is not given, we use the GLEC emission factors based on the length (short, medium, long haul) of the flight and the aircraft type (passenger, cargo or unknown).

The response contains total CO2e emissions and detailed emissions : CO2e WTT (well-to-tank) emissions and CO2e TTW (tank-to-wheels) in g for the amount of goods carried.

The weight of the transported goods can be given. If no weight is specified, the API returns the amount of CO2e for 1 metric ton of goods.

The response contains the parameters passed in the request and the used values of the parameters if they were not passed.

The properties field contains useful information about the data that was used for the calculation. For example the name, and model of the aircraft, the distance, etc. The property dataType precise if the data used to calculate the CO2 emissions is default data (representarive of average operating practices) or modeled data (taking into account vehicle information).

The method uses CO2e emission factors from fuel consumption and distance calculation in accordance with EN 16258.
