Question to the Department for Transport:

To ask the Secretary of State for Transport, what assessment he has made of the capacity of the UK to produce (a) sustainable and (b) synthetic fuel to power RAF flights.

Sustainable aviation fuel (SAF) is a key technology to achieve Jet Zero, being supported by three key policy pillars: the SAF mandate; the capital grant programmes; and considerations on support for longer-term commercialisation. The MoD is proactively engaged in the Jet Zero Strategy and the proposed UK SAF Mandate strategy.

The MoD will use increasingly greater aviation fuel SAF blends (which are currently limited to 50% blends) as they become more commercially available and cost effective, are supplied in the aviation fuel supply chain via SAF mandates, equal or enhance operational output and tasks, and support wider government requirements. DfT, MoD and UK civil aviation stakeholders are developing options to increase UK SAF production capacity.
