Biofuel-based sustainable aviation fuel (SAF), made from materials like used cooking oil or wood chips, could reduce aviation emissions by up to 80%, according to government and industry officials, and is seen as the key green solution for the sector.
But there is a shortage of feedstocks to produce enough of the fuel from organic materials. Investment into pricier synthetic fuels made out of hydrogen or carbon capture, known as e-SAFs, is needed to ensure Europe can meet its green goals.
Only a handful of refineries produce e-SAF, which is considered to be even cleaner than biofuel-based SAF, and very few airlines have committed to purchasing it.
