The government has launched a consultation on plans to make fuel include five per cent bio fuel.
From April 2008 fuel suppliers would have to ensure that a certain percentage of their sales are made up of bio fuels. And by 2010, the government wants five per cent of all the fuel sold to come from a renewable source.
It reckons this will save a million tonnes of carbon a year.
Transport minister Stephen Ladyman said the plan would play a key role in making road transport fuels greener.
“In carbon terms, it’s expected to be the equivalent of taking a million cars off the road by 2010.”
The consultation will finish on 17 May.
