The International Aviation Transport Authority says these fuels can be derived from biofuels or fuels from alternative sources. Feedstocks for SAF can range from cooking oil, plant oils, municipal waste to agricultural residues.
As the world pushes towards the Paris Climate Accord’s goal of “net zero emissions” by 2050, the aviation industry has also made strides to try to decarbonise the sector by introducing more efficient engines and lighter materials in planes (so less fuel will be burnt while flying), and more recently, using so-called sustainable aviation fuel (SAF).
One might wonder, what is SAF? Simply explained, it is a term used by the aviation industry to describe an aviation fuel that is not derived from fossil fuels.
