Question to the Department for Transport:

To ask the Secretary of State for Transport, if she will make an estimate of the proportion of farmland that will be used to produce alternative aviation fuels in (a) 2030, (b) 2040 and (c) 2050.

The Sustainable Aviation Fuel (SAF) mandate introduced in January 2025 sets targets for the future supply of low carbon alternatives to fossil fuels used in aviation. The scheme only supports SAF made from sustainable wastes or residues (such as used cooking oil or forestry residues), recycled carbon fuels (e.g. unrecyclable plastics), or be power to liquid fuels made using low carbon (renewable or nuclear) electricity. Given these feedstocks do not require land there is no impact on farmland.
