Eurocontrol said 39 of 1657 EUairports accounted for 80% of conventional fuel usage by departing aircraft in 2019.
The industry group said in a statement that it projects that providing a 12.5% sustainable aviation fuel (SAF) blend to these airports would result in an 8% reduction in CO2 emissions by 2030, a more efficient measure than evenly distributing SAF across all 1657 airports.
It said seven of these airports (Frankfurt, Paris Charles de Gaulle, Amsterdam Schiphol, Helsinki, Stockholm Arlanda, Hamburg, and Munich) currently supply SAF.
Eurocontrol added that at current prices, the use of 12.5% SAF would lead to a 12.5% increase in fuel costs for airlines. SAF currently represents 0.05% of total jet fuel consumption in Europe.
