To ask the Secretary of State for Transport, what steps his Department are taking to help ensure that 10% sustainable aviation fuels are blended in the UK jet fuel mix by 2030.

Following a public consultation, in July 2022, Government confirmed that a sustainable aviation fuels (SAF) mandate would be introduced in 2025, requiring at least 10% (around 1.5 billion litres) of jet fuel to be made from sustainable feedstocks by 2030.

As part of our second consultation published in March 2023, we proposed a range of trajectories for the mandate from 2025 to 2040, all of which would deliver 10% SAF by 2030. We will confirm the trajectories in the forthcoming government response.

We are also taking steps to develop a UK SAF industry and have a commitment to see at least five plants under construction by 2025. We have already funded 5 projects through the Advanced Fuels Fund (AFF), each receiving a share of £82.5m, with an announcement on the second-round winners expected in November 2023.

The Government recognises that uncertainty over future revenues remains a key barrier to investment in SAF production in the UK. In September, the Government committed to introduce a revenue certainty mechanism to support Sustainable Aviation Fuel (SAF) production in the UK. Alongside this announcement, the government published a delivery plan outlining the timeline for how such a mechanism could be delivered by 2026.
