Question to the Department for Transport:

To ask the Secretary of State for Transport, what assessment she has made of progress in meeting sustainable aviation fuel targets.

The sustainable aviation fuel (SAF) Mandate – which came into effect at the start of this year - is the UK’s key policy to decarbonise jet fuel. It obligates the supply of an increasing amount of SAF in the overall UK aviation fuel mix; starting at 2% in 2025, reaching 10% in 2030 and 22% in 2040.

The Government has considered feedstock availability and SAF technology readiness in setting targets which are both ambitious and deliverable. To support delivery of the Mandate’s targets, we are taking actions to grow supply of SAF. We are providing £135m to support 13 UK SAF projects through the Advanced Fuels Fund and have allocated an additional £63m of funding to March 2026.

The Government has also committed to introduce an industry-funded revenue certainty mechanism.
