The Department for Transport (DfT) has launched a consultation on whether and how it should introduce E10 fuel – which contains more bioethanol than traditional petrol – to the UK market.

The changes to the Renewable Transport Fuels Obligation (RTFO) announced earlier this year require transport fuel suppliers to increase the amount of renewable fuel supplied across the UK up to 2032.

To meet these new targets, fuel suppliers could choose to increase the percentage of bioethanol in petrol beyond the current 5% (E5) up to a limit of 10% (E10).

Filling up with E10 fuel reduces the greenhouse gas emissions of a petrol vehicle by around 2%. However, according to industry figures, there could be around one million cars within the UK that are unsuitable for use with E10.

Transport minister Jesse Norman said: “This government is ambitiously seeking to reduce the UK’s reliance on imported fossil fuels and cut carbon emissions from transport. But drivers of older vehicles should not be hit hard in the pocket as a result.

“We have launched this consultation in order to understand the impact of E10 on the UK market better, and to ensure that drivers are protected if any changes come into effect.”

The consultation also includes proposals on introducing new fuel labels at filling stations and on new vehicles to help motorists select the right the fuel.

The Government consultation will seek views on:

• Whether and how to introduce E10 petrol in the UK
• The reintroduction of an E5 protection grade to ensure standard petrol remains available at an affordable price
• The introduction of new fuel labelling at petrol pumps and on new cars

The eight-week consultation closes on September 16, 2018.
