Question to the Ministry of Defence:

To ask the Secretary of State for Defence, whether his Department collates information on (a) which flights use sustainable aviation fuel and (b) the proportion of sustainable aviation fuel used for flights (i) from a military airfield and (b) by a military vehicle.

Due to the increasingly routine use of blended sustainable aviation fuel (SAF), the Department does not collate detailed information on which flights use blended SAF, nor the proportion of SAF used against individual flights. For example, alongside conventional fuel RAF Lossiemouth took delivery of over nine million litres of blended SAF in 2024 for routine use in refuelling all aircraft at the Station.

As part of the UK SAF mandate and the Government pathway to net-zero aviation, from 1 January 2025 all aviation fuel procured will include SAF.
