U.S. Biofuels Policy Contributes to Global Warming

U.S. renewable fuel mandates are contributing to global warming, boosting carbon emissions as farmers turn carbon-rich areas like wetlands and forests into cropland to grow corn, soy and wheat for biofuels production, a study presented on Wednesday said.

Three scientists from the University of Wisconsin presented their findings in Fort Worth, Texas, at a conference hosted by the National Wildlife Federation, an environmental group that opposes U.S. biofuels mandates in their current form.

The scientists said it could take 50 years for biofuels to reduce carbon emissions as they were designed to do, since any reduction stemming from blending them into petroleum products is offset by more carbon emissions from clearing new farmland.

Lead author Seth Spawn said the study showed the mandate had “far-reaching impacts on the climate through its effects on the land and the carbon that is stores,” according to a National Wildlife Federation press release.
