Question to the Department for Transport:

To ask the Secretary of State for Transport, what steps her Department is taking to encourage the use of hydrotreated vegetable oil in the domestic production of sustainable aviation fuel.

Hydrotreated vegetable oil is a low carbon fuel made from oils and fats, which is used in rail or road transport.

Oils and fats are also used to make a type of sustainable aviation fuel (SAF) called HEFA or hydroprocessed esters and fatty acids. HEFA will play a vital role in our aviation decarbonisation journey. The UK is already producing and supplying this type of SAF, and we welcome the further development of this industry. The supply of HEFA SAF is incentivised by the UK’s SAF Mandate, which came into force this year. The SAF Mandate could deliver up to 6.3 megatonnes of carbon savings per year by 2040.
