Increasing production of biofuels to combat climate change will release between two and nine times more carbon gases over the next 30 years than fossil fuels, according to the first comprehensive analysis of emissions from biofuels.
Biofuels - petrol and diesel extracted from plants - are presented as an environmentally friendly alternative to fossil fuels because the crops absorb carbon dioxide from the atmosphere as they grow.
The study warns that forests must not be cleared to make way for biofuel crops. Clearing forests produces an immediate release of carbon gases into the atmosphere, accompanied by a loss of habitats, wildlife and livelihoods, the researchers said.
