Question to the Department for Transport:

To ask the Secretary of State for Transport, what discussions he has had with Cabinet colleagues on proposed changes to the hydroprocessed esters and fatty acids (HEFA) cap.

There are no proposals to change the HEFA cap which forms part of the SAF mandate scheme introduced on January 1 this year. It is recognised that HEFA will play an important role in the global SAF sector, particularly in the early years of the scheme. To this end there is no cap on HEFA supplied under the SAF mandate this year or next, and thereafter the cap is applied gradually decreasing the contribution of HEFA to 71% in 2030. The SAF mandate does not cap the production of SAF in the UK. It enables more advanced sustainable aviation fuels to be developed whilst supporting a UK market for HEFA in a way which recognises sustainable feedstocks used to produce HEFA are finite.

Any proposals to amend or remove the cap would require legislation. They would be subject to public consultation and cabinet committee clearances.
