Question to the Department for Transport:

To ask the Secretary of State for Transport, what has been the change in the volume of sustainable aviation fuel production in the UK between 2019 and 2024.

We do not hold statistics on volumes of SAF produced in the UK. SAF volumes are reported to the Department by fuel suppliers to discharge their obligations under the SAF mandate, and between 2019 and 2024, under the Renewable Transport Fuel Obligation (RTFO). SAF is not yet produced globally at a large scale. In the UK the only commercial scale SAF producer is at Phillips 66’s Humberside refinery.

Looking forward, the Government is taking decisive action to scale up UK SAF production. From 1 January 2025, the SAF mandate came into effect, setting a clear trajectory for growth – 10% of UK aviation fuel is required to be SAF by 2030 and 22% by 2040. To help deliver this, £63 million in grant funding has been allocated through the Advanced Fuels Fund for the current year to support UK SAF plants, with continued support for SAF production through to 2029/30. We have also introduced a SAF Bill that will establish a Revenue Certainty Mechanism, giving investors confidence to build and operate SAF facilities in the UK.
