Question to the Department for Transport:

To ask the Secretary of State for Transport, what assessment has been made of whether Sustainable Aviation Fuel market prices are consistent with the price assumptions used in the Sustainable Aviation Fuel Mandate cost-benefit analysis.

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.
