Sustainable Aviation Fuels (SAF)
SAF is a liquid fuel currently used in commercial aviation which reduces CO2 emissions by up to 80%. It can be produced from a number of sources (feedstock) including waste oil and fats, green and municipal waste and non-food crops. It can also be produced synthetically via a process that captures carbon directly from the air. It is ‘sustainable’ because the raw feedstock does not compete with food crops or water supplies, or is responsible for forest degradation. Whereas fossil fuels add to the overall level of CO2 by emitting carbon that had been previously locked away, SAF recycles the CO2 which has been absorbed by the biomass used in the feedstock during the course of its life.
