Question to the Department for Transport:

To ask the Secretary of State for Transport, pursuant to the Answer of 19 October 2026 to Question 33822, whether her Department has (a) made and (b) holds updated assessments of the potential impact of SAF buyout payments on air fares since the publication of the 2024 SAF Mandate Cost Benefit Analysis.

The most recent assessment remains the SAF Mandate Cost Benefit Analysis published in 2024, which considered a range of scenarios, including those in which the buyout mechanism was used. The actual impact on air fares will depend on a range of factors, including future SAF prices and supply. Any revision to estimates will be undertaken as part of future policy development, taking account of emerging evidence and analysis.
