"MPs have urged for the introduction of controversial E10 fuel by 2020 at the latest, believing that adding more ethanol to the petrol sold in the UK would cut carbon by the equivalent of taking 700,000 cars off the road and help the struggling British biofuel industry. That’s despite E10 being potentially harmful to older vehicles and leaving owners out of pocket as they must fork out for costlier alternatives.
E10 is a biofuel made up of 90 per cent regular unleaded and 10 per cent ethanol – hence its name. Unlike regular unleaded petrol, ethanol absorbs carbon dioxide, partially offsetting greenhouse gas emissions. However, while E10 has become widely available in several other counties and now accounts for 47 per cent of the petrol market in France, it’s yet to be made available in the UK despite the debate over its sale rumbling on for several years."
