Aviation: Alternative Fuels
The question
To ask the Secretary of State for Transport, pursuant to the answer of 15 June 2026 to Question 7033, what assumption on the proportion of Sustainable Aviation Fuel Mandate compliance costs being passed through to passengers was used in the Department's cost-benefit analysis.
Answered by Keir Mather
We recognise the need to protect consumers and factored this into the design of the Sustainable Aviation Fuel Mandate through the inclusion of a buyout option for obligated suppliers, which protects end users (passengers) from excessive costs.
The Sustainable Aviation Fuel Cost Benefit Analysis publication provides an assessment of the ticket price impacts of the SAF Mandate, including a detailed description of the pass-through assumption (Section 3; Annex 7.4).
