Maybe they're not the answer, or at least not the only answer. Deciding between fuel or food is ridiculous.
Supporters argue that biofuels can reduce greenhouse gas emissions, because the plants they are made from absorb carbon dioxide from the air. But a number of studies have raised doubts about the green credentials of many of the leading candidates, such as palm oil and ethanol made from corn. Critics say biofuels compete for land with staple food crops, and vast areas of rainforest are cleared to grow them.
Dimas told the BBC: "We have seen that the environmental problems caused by biofuels and also the social problems are bigger than we thought they were." He said the EU would "move carefully" on the issue. "We have to have criteria for sustainability, including social and environmental issues, because there are some benefits from biofuels."
