The supply of renewable fuel (commonly referred to as biofuel) is measured annually as required under the Renewable Transport Fuel Obligation (RTFO). Figures for each reporting year are updated and published quarterly, and revised several times until final. There will be up to 6 quarterly reports for each year, except for 2018 which is a short year, running from April to December 2018, and will have 5 reports.
These reports contain final statistics on volumes of fuel supplied, Renewable Transport Fuel Certificates issued, the carbon and sustainability performance of individual suppliers and a comparison to previous periods.
Past provisional reports were published to provide an indication of renewable fuel supply in their respective reporting year before complete data was available. Only the final report for each reporting year has final figures for the obligation period. For more information, see the About renewable fuel data and reports section below. All reports, provisional and final, for each reporting year are available.
All the statistics published in this series are Official Statistics. The department’s view is that all statistics which are not designated as National Statistics are robust and have been produced to a suitable standard.
The RTFO is one of the government’s main policies for reducing greenhouse gas emissions from fuel supplied for use in transport. Under the RTFO, all road transport fossil fuel suppliers are required to provide a volume of sustainable renewable fuel as a percentage of the total road and non-road mobile machinery fuels they supply. By 2020, 9.75% of all fuel supplied by fossil fuel companies is required to be renewable. Similarly, under the RTFO, suppliers are also required to submit reports on the carbon and sustainability standards of the renewable fuels.
All quarterly reports 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 figures published prior to the final report for each period are provisional.
The final figures for each obligation period are usually in report 6. 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 reports themselves.
