Calculate Carbon Emission of Flights

Calculate GHG emissions from air travel and cargo for short- and long-haul flights. Automate emission measurements for passenger flights and air freight inside your software

How it works

Use IATA airport codes for origin and destination for single flights or multiple flight legs to automatically determine flight distance and burned fuel. The API will automatically add the correct distance uplift and select the right emission factor to calculate the emissions caused by this shipment or journey.

Specify passenger load factor, flight class, aircraft type (coming soon), or cargo weight for air freight to obtain accurate CO2e estimates for the travelled route.

Compliant, unbiased, and transparent carbon insights

Access reliable estimates underpinned by the latest scientific methodology, free from conflict of interest from the sale of carbon offsets.


Accredited data and methodology, fully aligned with GHG Protocol and SBTi requirements


Regularly updated data and methodologies, vetted by our in-house climate scientists and overseen by our Scientific Advisory Board


Audit-ready calculation trail including applied emission factor, data source, year valid, and more
