Question to the Department for Transport:

To ask the Secretary of State for Transport, what assessment he has made of the potential merits of classifying biodiesel that is 100 per cent derived from waste biomass separately from biodiesel made from non-waste biomass.

The Department recognises the benefits that fuels produced from waste can have in reducing carbon emissions. It is anticipated the merits of any new classification for biodiesel proposed would relate to better informing the public or incentivising the uptake of waste derived biodiesel.

The industry standard for diesel and UK regulations make no requirement in respect of the labelling by feedstock type of biodiesel blended into diesel and placed on sale in UK forecourts. There is little merit in introducing such a requirement and given the complexity of fuel supply chains it is likely this information will not always be known at the point of sale.

The Renewable Transport Fuel Obligation (RTFO) was changed in 2011 so that waste derived biodiesel is eligible for twice the number of tradeable certificates than would be rewarded for biodiesel produced from non-wastes. One benefit of the change in approach is that the RTFO scheme also sets mandatory sustainability criteria which must be met in order for renewable fuels to benefit from any support. Thereby ensuing we reward fuels that deliver reductions in greenhouse gas emissions.

The RTFO has been highly successful in supporting a market for waste derived biofuels. In 2019 over two-thirds (69%) of renewable fuels reported under the RTFO were made from wastes and around four fifths (79%) of biodiesel reported was made from used cooking oil, a waste.
