Flight API

Calculate the carbon emission of a single flight or multiple flights at once. Specify the origin airport, the destination and the seat class. We support more advanced parameters, such as stopover, number of passengers and one-way/roundtrips.

The formula to calculate carbon emissions of flights is developed and updated by myclimate. It is renowned and well documented.

All changes made for version 1.0.1, including updates to the calculation formula, can be reviewed in our changelog, ensuring you stay informed about the latest modifications and improvements to our flight carbon emission calculations.

Car API

Using our car API it is possible to calculate the carbon emission of one or multiple private car trips. We support a wide variety of fuels, such as petrol, diesel, biogas, and electric. If you are unsure how much fuel your car consumes, we provide average values depending on the type of car.

Cruise Ship API

Calculate the carbon emissions of a trip on a cruise ship. Specify the type of the ship and which kind of cabin you booked.

Contact us if you are interested in a more detailed calculation of your company's carbon emissions or if your company has additional sources of carbon emissions not covered here.

Footprint API
