ICAO has developed a new Application Programming Interface (API) for the ICAO Carbon Emissions Calculator that allows its automatic integration with software, webpages, or mobile applications released by third party organizations.
For more information on the ICEC API, please contact
The pricing grid for the use of the ICEC API is available

Terms and Conditions.
Try the ICEC API Demo (100 calls) per the following steps:
Step 1: Estimation of the aircraft fuel burn
Step 2: Calculation of the passengers' fuel burn based on a passenger/freight factor which is derived from RTK data
Step 3: Calculation of seats occupied (assumption: all aircraft are entirely configured with economic seats). Seat occupied = Total seats * Load Factor
Step 4: CO2 emissions per passenger = (Passengers' fuel burn * 3.16) / Seat occupied
Note: for flights above 3000 km, CO2 emissions per passenger in premium cabin = 2 x CO2 emissions per passenger in economy
