Sustainable Aviation Fuel (SAF) Mandate statistics
Supply of sustainable aviation fuels under the SAF Mandate in the UK.
The SAF Mandate statistics are a new set of statistics with the first publication coming out in August 2025. This aligns with the publication cycle of the Renewable Transport Fuel Obligation (RTFO) statistics.
The data tables report on aviation fuel supplied to the UK under the SAF Mandate, which came into effect as of January 1, 2025.

Latest SAF Mandate statistics
The supply of SAF is measured annually as required under the SAF Mandate.
Figures for each reporting year are updated, revised and published quarterly until final. The final report, with a complete dataset for the year, will typically be published in the subsequent winter of the reporting year.

About SAF Mandate data and reports
All the statistics published in this series are official statistics. The department’s view is that all statistics which are not designated as accredited official statistics are robust and have been produced to a suitable standard.
The SAF Mandate is the UK’s key policy to decarbonise jet fuel and is the UK’s key policy mechanism to secure demand for SAF. It delivers greenhouse gas (GHG) emission savings by encouraging the supply of SAF within the aviation industry. It does this by setting a legal obligation on fossil jet fuel suppliers in the UK to supply an increasing proportion of SAF over time. Suppliers will receive certificates for the SAF they supply. The number of certificates they receive will be issued in proportion to the level of GHG emission reductions that fuel delivered.
The SAF Mandate obligation starts at 2% of total UK jet fuel demand in 2025, increasing linearly to 10% in 2030 and then to 22% in 2040. Suppliers are required to submit reports on the carbon and sustainability standards of the low carbon fuels.
All provisional tables contain fuel volumes which are cross-verified with HMRC data. However, as suppliers can provide their data up to 7 months after the obligation period ends, all data published prior to the final report for each obligation period subject to change.
The final figures for each obligation period are usually published in the subsequent winter of the reporting year. There can be some discrepancy between the provisional and final figures so provisional reports should be viewed as indicative rather than definitive. Further information on provisional data is contained within the data tables themselves.
