Sustainable Aviation Fuel (SAF) Mandate
The SAF Mandate is the UK’s key policy to decarbonise aviation fuel by encouraging the supply of sustainable aviation fuels.
The Sustainable Aviation Fuel (SAF) Mandate secures demand for SAF by:
- obligating the supply of an increasing amount of SAF in the overall UK aviation fuel mix
- incentivising SAF supply through the award of tradeable certificates with a cash value
The SAF Mandate starts in 2025 at 2% of total UK jet fuel demand, increasing linearly to 10% in 2030 and then to 22% in 2040.
From 2040, the obligation will remain at 22% of total UK jet fuel demand until there is greater certainty regarding SAF supply.
The SAF Mandate could deliver up to 6.3 megatonnes of carbon savings per year by 2040.
The SAF Mandate and the Renewable Transport Fuel Obligation (RTFO) are part of the government’s low carbon fuel strategy.

Apply for a SAF Mandate account
You must register under the SAF Mandate if your company owns and supplies 15.9 terajoules or more of relevant aviation turbine fuel for use in the UK during an obligation year (1 January to 31 December).
SAF guidance
Voluntary schemes and recognised verifiers
Fuel suppliers applying for certificates under the SAF Mandate must have their claims independently verified. The department publishes a list of voluntary schemes which can be used to provide supporting evidence of compliance and a list of third party verifiers that have been recognised as providing evidence of ‘appropriate expertise’ with the SAF Mandate.
