EPA: ethanol crops displaces climate-friendly onesMay 5, 2009 By H. JOSEF HEBERT , Associated Press Writer in Earth / Environment
(AP) -- The Environmental Protection Agency says that corn ethanol - as made today - wouldn't meet a congressional requirement that ethanol produce 20 percent less greenhouse gas than gasoline. But the agency said it is still more climate friendly than gasoline.
The EPA in its analysis said that even if worldwide land-use changes are taken into account, ethanol would still produce 16 percent less greenhouse gases than the gasoline it is replacing.
EPA Administrator Lisa Jackson said Tuesday that future improvements in production technologies are expected to make ethanol and other biofuels more climate friendly so they can meet the legal requirement. The requirement for a 20 percent improvement in climate impact applies only to ethanol from future production plants and exempts fuel made at existing facilities.
