Net CO2 emissions from residue removal are not adequately characterized in biofuel life cycle assessment”. A $500,000 study – paid for by the U.S. federal government and released last Sunday in the peer-reviewed journal Nature Climate Change – concludes that biofuels made with corn residue release 7% more greenhouse gases in the early years compared with conventional gasoline.
