A further warning that biofuels are not the answer. This time with a bit more research to boot. "Dr Righelato's study, with Dominick Spracklen from the University of Leeds, is the first to calculate the impact of biofuel carbon emissions across the whole cycle of planting, extraction and conversion into fuel. They report in the journal Science that between two and nine times more carbon emissions are avoided by trapping carbon in trees and forest soil than by replacing fossil fuels with biofuels. Around 40% of Europe's agricultural land would be needed to grow biofuel crops to meet the 10% fossil fuel substitution target. That demand on arable land cannot be met in the EU or the US, say the scientists, so is likely to shift the burden on land in developing countries. The National Farmers Union said 20% of Britain's agricultural land could be used to grow biofuels by 2010. However, the researchers say reforesting the land would be a better way to reduce emissions."
It should be said, also, that in the UK, more trees in the right places might well help with rainwater run-off ...!
