UK Renewable Transport Fuel Supply Data Released for 2025

The Department for Transport has released its fifth provisional set of statistics covering the supply of renewable transport fuels in the United Kingdom for January to December 2025, giving the clearest picture yet of how the country's fuel mix is shifting under the Renewable Transport Fuel Obligation.

The Renewable Transport Fuel Obligation requires fuel suppliers to blend a rising proportion of renewable fuel into the transport fuel they sell each year. This framework is one of the main tools the UK government uses to cut carbon emissions from road vehicles, and the figures released by the Department for Transport track how much renewable fuel is actually entering the supply chain against those legal requirements.

For ordinary drivers, the practical effect of the RTFO is already visible at the pump. Most petrol sold in the UK now contains up to 10 per cent ethanol, and diesel contains a proportion of biodiesel, both of which count towards the renewable fuel totals recorded in these statistics. Whether you drive a petrol, diesel or flex-fuel vehicle, the fuel you buy today is already a blend, and that blend is set to become progressively greener as annual targets rise.

The data tables published alongside the provisional release allow anyone to examine the breakdown of renewable fuel types, volumes supplied and the certificates issued to fuel producers who meet their obligations. Drivers thinking about how these changes affect running costs or the long-term case for switching to an alternatively fuelled vehicle can find independent guidance and vehicle comparisons at Car.co.uk, which covers the full range of fuel types available to UK buyers.

Further revisions to the 2025 figures are expected as the Department for Transport processes additional returns from fuel suppliers, so the numbers may be updated before a final release is published.
