Aviation: Alternative Fuels
The question
To ask the Secretary of State for Transport, what steps her Department is taking to ensure the supply of sustainable aviation fuel increases to match demand.
Answered by Keir Mather
The Department for Transport is taking a comprehensive approach to ensure the supply of sustainable aviation fuel (SAF) increases to match demand. In January 2025, the Government introduced the SAF Mandate, obligating jet fuel suppliers to blend increasing volumes of SAF into the UK aviation fuel mix, with targets rising from 2% in 2025 to 10% in 2030 and 22% in 2040. These targets were set following detailed analysis and engagement with industry stakeholders. To ensure the SAF Mandate reflects the latest technological and commercial developments, regular review points are built into the legislation, allowing targets to be revisited if required. The first formal review will be carried out before 2030.
To support supply, £63 million in grant funding has been allocated through the Advanced Fuels Fund for the current year, with continued support for SAF production through to 2029/30. The UK SAF Clearing House provides advice and support to SAF producers navigating the fuel testing landscape, helping to remove barriers to new fuels coming to market.
In addition, the Government has introduced legislation for a Revenue Certainty Mechanism to increase investor confidence and unlock investment in UK SAF production.
