Developed by international experts under ICAO’s Committee on Aviation Environmental Protection, the ICAO Carbon Emissions Calculator API applies a globally harmonized methodology to calculate CO2 emissions from air travel. It provides CO2 emissions estimates for both passenger and freighter operations, supporting users in assessing and reporting their environmental impact.
The methodology applies the best available industry data to account for various factors such as aircraft types, route-specific data, passenger load factors and cargo carried.
