Aviation: Alternative Fuels

Question

To ask the Secretary of State for Transport, pursuant to the answer of 15 June 2026 to Question 7033, what estimate was made in the Sustainable Aviation Fuel Mandate cost-benefit analysis of the increase in average airfare per passenger in each year from 2025 to 2040 arising from compliance with the mandate.

Answer

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 (Section 4) and a thorough validation of the price assumptions against literature and market data (Section 3) The full cost benefit analysis is available at: https://assets.publishing.service.gov.uk/media/66601969dc15efdddf1a872d/uk-saf-mandate-final-stage-cost-benefit-analysis.pdf.
