Aviation: Alternative Fuels

Asked by Mr Richard HoldenConservativeDepartment for TransportTabled Answered 29 June 2026UIN 11458

The question

To ask the Secretary of State for Transport, what assessment her Department has made of the potential impact of Sustainable Aviation Fuel Mandate compliance costs on the commercial viability of domestic air routes.

Answered by Keir Mather

The SAF Mandate is designed to protect against excessive costs being passed on to passengers with a buyout option for obligated suppliers. How airlines choose to balance costs between domestic and international routes will be a commercial decision for each airline. As such, it is not possible to predict how individual airlines will choose to do this or the impacts this will have on domestic routes.
