The head of the UN Environment Programme has warned that the biofuel market could crash if suitable environmental standards aren't established. According to the BBC, "Achim Steiner... said there was an urgent need for standards to make sure rainforests weren't being destroyed." The story also picked out Indonesia's tropical peatlands for special mention of what it terms "biofuel folly". (Nice phrase, I'll have to remember that one!)
Mind you, Steiner was making those comments in response to an independent group of scientists who criticsied the stance taken by the Intergovernmental Panel on Climate Change (IPCC) on biofuels, which was described as "naive".
"One of the scientists, Tad Patzek from University of California Berkeley, US, said: "In the long-run, the planet cannot afford to produce biofuels because we're going to run out of the land and water and environmental resources. In addition, because of the land use changes, drying up peat-swamps, burning tropical forest, these biofuels involve up-front enormous emissions of greenhouse gases that will never be recouped by their later use," he told BBC News."
There's also a link to a neat primer on the history and nature of biofuels which I haven't come across before, giving some context to the environmental debate. As anyone who saw QI the other week will know, Rudolph Diesel (inventor of the engine, not the jeans) designed vehicles to run on biofuels, not petrochemical ones - a good one to remember for pub quizzes.
