"Production data published by the Department for Transport (DfT) covering most of 2025 shows that sustainable fuels (SAF) only accounted for 1.6% of fuel supplied for UK flights 20% less fuel in volume than the 2% needed to fulfil the requirement. The government introduced the mandate in January, which requires suppliers to hit targets for SAF which the industry has argued is important for cutting its carbon emissions within the overall UK aviation fuel mix."
"So far, the supply of SAF has been exclusively produced from recycled cooking oil from Asia, predominantly China, the DfT figures showed. The data shows that a little more than 160m litres (35m gallons) of SAF was used, out of 10bn litres of jet fuel burned in UK flying until early October. The DfT said the time needed for verification meant that the figures were provisional, and final figures for the year were not expected to be published until November 2026."
Department for Transport data for most of 2025 shows sustainable aviation fuel accounted for 1.6% of fuel supplied for UK flights, around 20% below the 2% mandate. The mandate began in January and increases to 10% by 2030 and 22% by 2040, including second‑generation fuels. SAF supply to date has come exclusively from recycled cooking oil sourced from Asia, mainly China. Roughly 160 million litres of SAF were used out of about 10 billion litres of jet fuel burned to early October. Figures are provisional pending verification and incomplete supplier reporting. Planes emit similar CO2 in flight, but SAF lowers net carbon footprint through its production pathways. SAF production and uptake are regarded as essential for cutting commercial, especially long‑haul, aviation emissions despite scientific and environmental scepticism.
