Studies Say Clearing Land for Biofuels Will Aid Warming

From The Washington Post:

Clearing land to produce biofuels such as ethanol will do more to exacerbate global warming than using gasoline or other fossil fuels, two scientific studies show.

The independent analyses, which will be published today in the journal Science, could force policymakers in the United States and Europe to reevaluate incentives they have adopted to spur production of ethanol-based fuels. President Bush and many members of Congress have touted expanding biofuel use as an integral element of the nation's battle against climate change, but these studies suggest that this strategy will damage the planet rather than help protect it.

One study -- written by a group of researchers from Princeton University, Woods Hole Research Center and Iowa State University along with an agriculture consultant -- concluded that over 30 years, use of traditional corn-based ethanol would produce twice as much greenhouse gas emissions as regular gasoline. Another analysis, written by a Nature Conservancy scientist along with University of Minnesota researchers, found that converting rainforests, peatlands, savannas or grasslands in Southeast Asia and Latin America to produce biofuels will increase global warming pollution for decades, if not centuries.
