In what may be this week's worst amendment to the Waxman-Markey climate bill, a midwestern Congressman has introduced a provision that would ban the EPA from accounting for the full carbon footprint of biofuels.
Collin Peterson (D-Minn.), the powerful chair of the House Committee on Agriculture, is expected to attach the amendment before releasing the bill to the House floor, where a vote is expected as early as tomorrow. The change would prevent the EPA from accounting for the way that growing biofuel crops in the U.S. drives food production abroad, causing deforestation that contributes to climate change. Ignoring this "indirect land-use change"--the technical term for a phenemon that can account for up to 40 percent of corn-based ethanol's carbon emissions--would allow the fuel to qualify under the 2007 Renewable Fuel Standard, making it eligible for government subsidies.
In effect, the ethanol industry is hiding behind the difficulty of calculating its own environmental footprint. Though the EPA has already devised a method to account for the land-use impacts of biofuels, the amendment prohibits the agency from implementing it for six years, at which point the National Academy of Sciences will have completed a study that is supposed to resolve lingering uncertanties with the method.
