Question to the Department for Transport:

To ask the Secretary of State for Transport, what estimate her Department has made of the amount of agricultural land required for bio-aviation fuels to meet (a) existing and (b) potential demand to allow for expansion of (i) Heathrow airport and (ii) other UK airports.

The Sustainable Aviation Fuel (SAF) mandate scheme is driving the uptake of lower carbon fuels used in aviation. The scheme does not support the supply of biofuels made from food, feed or energy crops. SAF must be 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, no estimate has been made of the amount of agricultural land required for bio-aviation fuels, under current or future demands.
