SAF — Sustainable Aviation Fuel — is the next generation of cleaner aviation fuels. Made from a wide variety of feedstocks including agricultural and household waste, purpose-grown crops, and captured carbon, rather than fossil fuels.

Crucially, SAF is chemically almost identical to conventional jet fuel. It can be blended straight into aircraft engines already in use today. No new planes. No new infrastructure required. It is cleaner to produce and cleaner to burn, producing fewer pollutants and improving local air quality at and around airports.

Britain will need SAF from a range of sources — international and domestic — to meet demand at an affordable price. That diversity of supply is itself a strength. And producing a meaningful share here in the UK adds a critical layer of energy security for the long term.
