Question to the Ministry of Defence:

To ask the Secretary of State for Defence, how much the RAF has spent on Sustainable Aviation Fuel in each of the last 5 years a) in total each year and b) in average price per litre each year.

The Ministry of Defence cannot accurately determine RAF expenditure on Sustainable Aviation Fuel (SAF) or an average SAF price per litre because aviation fuel is purchased as a mandate-compliant product rather than as separately identifiable SAF and conventional fuel. Any figures provided would therefore be estimates derived from fuel consumption data and publicly available market pricing information.
