ICAO Carbon Emissions Calculator (ICEC)

ICAO has developed a methodology to calculate the carbon dioxide emissions from air travel for use in offset programmes. The methodology applies the best publicly available industry data to account for various factors such as aircraft types, route-specific data, passenger load factors and cargo carried.

The ICAO Carbon Emissions Calculator allows passengers to estimate the emissions attributed to their air travel. It is simple to use and requires minimal user information. ICEC is the only internationally approved tool to estimate carbon emissions from air travel. Click on the image below to access the ICEC web.

 

Please officeenv [at] icao.int (contact us) or refer FAQ or see the accompanying methodology to the ICAO Carbon Emissions Calculator for additional information.
