A U.K. think tank is calling on European governments to support research into commercially viable biofuels for aviation. Policy Exchange, in a report entitled "Green Skies Thinking," says: "Sustainable bio-jet fuels are one critical option that can be delivered over the medium term, in time to make a significant contribution to our 2050 emission reduction targets. For this to work, ambitious policies need to be put in place urgently and with the conviction needed to meet the global challenge we face." The report argues against prioritizing biofuels for autos, on the grounds that the acreage required to grow the fuel sources would reduce the world's food supply and drive up prices.
