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.
