We take the total number of hours we have been flying during the last year from the flight log of the aircraft. From the total hours, we make a rough estimate of the total fuel burned based on the average fuel burn per hour/aircraft type and then compensate our CO2 emission through the Dutch organisation Trees for all. Trees are planed in Bolivia compensating our CO2 emission.

Each litre of AVGAS fuel is responsible for 2.2 kg of CO2 emissions.
