Use of U.S. croplands for biofuels increases greenhouse gases through emissions from land-use change

  • 29/02/2008

Most prior studies have found that substituting biofuels for gasoline will reduce greenhouse gases because biofuels sequester carbon through the growth of the feedstock. These analyses have failed to count the carbon emissions that occur as farmers worldwide respond to higher prices and convert forest and grassland to new cropland to replace the grain diverted to biofuels.
