Question to the Department for Transport:

To ask the Secretary of State for Transport, what assessment his Department has made of the effect of the introduction of E10 on UK (a) carbon emissions and (b) air pollution.

The document “Introducing E10 Petrol: consultation”, published by the Department in March 2020, notes that a switch to E10 could cut overall transport CO2 emissions by 750,000 tonnes per year, if it is combined with an increase to Renewable Transport Fuel Obligation (RTFO) targets. It also noted that we do not expect moving to E10 to deliver significant air quality benefits.
