|a 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 (or cropland) diverted to biofuels. Using a worldwide agricultural model to estimate
emissions from land use change, we found that corn-based ethanol, instead of producing a
20% savings, nearly doubles greenhouse emissions over 30 years and increases
greenhouse gases for 167 years. Biofuels from switchgrass, if grown on U.S. corn lands,
increase emissions by 50%. This result raises concerns about large biofuelmandates and
highlights the value of using waste products. |
