Question to the Department for Transport:

To ask the Secretary of State for Transport, what assessment he has made of the potential merits of increasing the amount of ethanol in petrol sold to reduce carbon emissions.

In 2018 the Department published a call for evidence on “E10 petrol, consumer protection and fuel pump labelling”. This document noted that using E10 (petrol containing up to 10% bioethanol) in place of E5 could reduce the net greenhouse gas emissions of a petrol vehicle by around two per cent.
