Industry in 2m tonne biofuel pact

European airlines, biofuel producers and the EC signed up yesterday to produce 2m tonnes of biofuel for aviation by 2020 even as debate rages over how green such fuels are. Airlines are keen to use biofuels as a way of cutting down on pollution from jet fuel but the use of food crops in their production has come under fire for taking land that could be used to grow food.
