Apr 20, 2009· Corn Ethanol Will Not Cut Greenhouse Gas Emissions. California regulators may rule that the biofuel is no better--and might be worse--than petroleum for solving climate change

Is Corn Ethanol a Low-Carbon Fuel?

Thus, we conclude that corn-based ethanol reduces greenhouse gas emissions. However, this conclusion may not hold if we extend our accounting boundary to include land use changes in other countries. As explained earlier, expansion of U.S. corn production for ethanol will reduce U.S. soybean production. But world soybean demand will be unaffected.
