To ask the Secretary of State for Transport, what steps his Department is taking to support the transition to sustainable aviation fuels.

We are supporting the transition to sustainable aviation fuels by taking action to build supply of sustainable aviation fuel (SAF) and secure demand.

The SAF Mandate will secure demand for SAF, by obligating the supply of SAF in the overall UK aviation fuel mix. The Mandate will require 2% of UK jet fuel to be made from sustainable sources in 2025, 10% in 2030 and 22% in 2040. It will incentivise SAF supply through the award of tradeable certificates with a cash value.

We are kickstarting a UK SAF industry by allocation £135m through our Advanced Fuels Fund, which is funding thirteen projects to reach completion and supporting our ambition to see five plants under construction in the UK by 2025. We are currently consulting on the introduction of a revenue certainty mechanism, which will help de-risk SAF projects in the UK by addressing barriers to investment in a nascent market.
