Rules to Limit Emissions in the Making of Ethanol

The Obama administration on Tuesday proposed rules to limit emissions of climate-changing gases from the manufacture of ethanol, a step that would probably curtail the expansion of corn ethanol production. But the Environmental Protection Agency also issued a draft rule Tuesday on a “renewable fuels standard,” including provisions on how much carbon dioxide can be released in the production of ethanol and other biofuels. The rule is intended to force the industry to help meet targets set by Congress in 2007 for reducing greenhouse-gas emissions from ethanol, even as legislators encourage its production as an alternative to gasoline. The proposed rules for calculating the emissions of biofuel producers do not apply to plants that were under construction by December 2007...NYTimes
