Frequently asked questions 

Read the most common question and answers regarding compensating your carbon footprint and offsetting your flight.

A carbon footprint is the greenhouse gas (GHG) emissions arising from a specific activity, such as your flight. The CO2 emissions of a flight depend on the aircraft used, the distance flown and the amount of passengers and cargo the aircraft carries.

You can choose how much of your contribution goes to Sustainable Aviation Fuel (SAF) and how much to support climate projects that reduce, capture or avoid greenhouse gas (GHG) emissions. The climate projects our service supports are certified by various credible and internationally recognized carbon certification standards such as the VCS, the Gold Standard, American Carbon Registry and Climate Action Reserve. 

Your compensation is not connected to your flight reservation, but you can claim for a refund through CHOOOSE by emailing The refund is not processed automatically if you cancel your flight.

Yes, as the compensation is not connected to your flight reservation, you can also compensate after you have flown.

The global availability of sustainable aviation fuel is limited, and it is three to five times more expensive than regular jet fuel. Price and availability will develop only through more extensive use, and that is why we want to invest in sustainable fuels.

CHOOOSE, who is Finnair's partner in providing this service, takes €0.35 per passenger per leg for administrative costs. 

The climate-tech company CHOOOSE™ is providing Finnair's SAF and carbon offset service and is guaranteeing that your contribution has a climate-positive impact. CHOOOSE delivers a platform that enables both individuals and organisations to easily connect with trusted climate solutions around the world. CHOOOSE carbon calculator calculates your carbon footprint and provides you with the option to seamlessly address your flight emissions through the combination of sustainable aviation fuel and verified climate projects.

Calculations are based on actual fuel consumption on Finnair's scheduled flights. Fuel consumption is a 12-month average and is allocated between passengers and belly cargo in accordance with ICAO allocation methods. Calculation results in CO2 emissions, where no other than direct emissions are accounted.

Our offset calculator results show only CO2 emissions, and only direct emissions are accounted for.  

In aviation, the method of calculating carbon dioxide emissions is jointly agreed, and it is used by e.g. airlines trade association IATA and it is also the starting point in the internationally recognized Science Based Targets initiative (SBTi). When the common calculation method is changed in such a way that other than direct carbon dioxide emissions are taken into account, we will of course use it as well. 

Currently, the proposed general factors do not take into account airline-specific indirect emissions or different types of flights, i.e. flight altitude and the time the aircraft fly in the upper atmosphere.
