Aviation: Alternative Fuels
The question
To ask the Secretary of State for Transport, pursuant to the Answer of 20 October 2025 to Question 78707, whether her Department has made a recent updated estimate of the additional cost per passenger per flight arising from the requirement for airlines to use 10% sustainable aviation fuel by 2030.
Answered by Keir Mather
I refer the Right Honourable Member to the answers I gave on 20 October, 23 October and 5 November 2025 to PQs UIN78707, UIN83374 and UIN85910.
The estimated costs of the requirement were assessed and published prior to the introduction of the SAF mandate in January last year. We will monitor the market to update our assumptions where necessary and to inform formal reviews.
