A minimum rate of "green" fuels will be imposed on aircraft departing from the continent. This law should reduce CO2 emissions from air transport by around two-thirds by 2050.

Aviation accounts for around 4% of European greenhouse gas emissions. The 2050 target falls short of what MEPs demanded (85%), but exceeds the European Commission's initial proposal (63%) taken up by member states. The agreement provides for a minimum share of 1.2% of synthetic fuels in the kerosene supplied by European airports.
