The calculation was made on the basis of the European Environment Agency. Plane emission factor is estimated to be 285g CO2/per km .
The European Environment Agency provides sound, independent information on the environment for those involved in developing, adopting, implementing and evaluating environmental policy, and also the general public.
If you know the quantity of CO2 in tonnes that you want to compensate, to know the amount of compensation, you need to multiply your quantity in tonnes by 22.
For 5 tonnes, the amount of compensation will be 5 × 22 = 110 euros

Acting for the climate means first identifying and then reducing the greenhouse gases that we emit on a daily basis and on which we can act at the source.
