Question to the Department for Transport:

To ask Her Majesty's Government what estimate they have made of the availability of biodiesel made from used cooking oil for vehicles in England.

In 2019 54% of total renewable fuel supplied under the Renewable Transport Fuel Obligation (RTFO) was produced from used cooking oil (UCO), this comprised seventy nine per cent of biodiesel.

Estimates of future volumes of renewable fuel supply were included in “Cost Benefit Analysis: Amendments to the Renewable Transport Fuel Obligations Order” which accompanied the Renewable Transport Fuels and Greenhouse Gas Emissions Regulations 2018. Appendix 3 of the cost benefit analysis includes estimates of total waste based biodiesel supply.
