Question to the Department for Transport:

To ask the Secretary of State for Transport, what estimate his Department has made of the potential impact on the reduction to CO2 emissions of the UK aviation sector switching to sustainable aviation fuels; and if he will make a statement.

Sustainable aviation fuels (SAF) can achieve lifecycle emissions savings of over 70% compared with conventional jet fuel, when fully replacing fossil kerosene.

The Jet Zero Strategy, published in July 2022, estimates that if SAF accounts for 10% of UK jet fuel supply, it could deliver a reduction of 2.41 Mt CO2 per year.

On 22 December the Department announced the five projects which will receive a share of the £165m Advanced Fuels Fund. The funding is available across three financial years, ending in 2024/2025.
