STROUD-BASED Euro candidate Molly Scott-Cato has re-ignited the debate on bio-fuels by calling for an end to a controversial subsidy scheme.
Subsidies are currently offered to crop growers who produce harvests that can be burned in power stations to create electricity.
But campaigners argue many biofuels produce more CO2 than they save.
Representing the Green Party, Molly said: "Land grabbing to cultivate biofuel crops is also proving damaging to natural habitats for many endangered species.
"All biofuels and sources of biomass are accepted as falling within the definition of 'renewable', even though in some cases they are found to be significant net carbon emitters.
"So they help the Government get towards its 20 per cent target, even though they do nothing to help us reduce our carbon emissions."
