*The annual funding gap for the development of net-zero technology and the production of Sustainable Aviation Fuel (SAF) is estimated to be 55 billion euros. When we divide this funding gap by the emissions from aviation, which amount to approximately 1 billion tonnes of CO2, we derive a responsibility metric: 5.50€ for every 100kg of CO2 emissions. So, even though the emissions have already occurred, contributing this amount helps decrease future dependency on conventional aviation and mitigates the climate impact of one's flight.
