“Biofuels have been put forward as a means of reducing the greenhouse gas emissions pumped out by fossil fuels but recent studies have questioned their impact when all factors, such as the use of fertilisers on the crops, are taken into account. Critics have been angered by the loss of tropical rainforests, which have been cleared to allow farmers to grow biofuel crops.

Deforestation has been calculated to account for about 18 per cent of world greenhouse gas emissions and Professor Beddington said that to destroy rainforests in order to grow biofuel crops was “insane”. He added: “Some of the biofuels are hopeless, in the sense that the idea that you cut down rainforest to actually grow biofuels seems profoundly stupid.” He said that human ingenuity was extraordinary and he was confident that food production could be boosted, including by growing genetically modified crops.”
