Two Department of Energy Department researchers have responded to a study which claims that biofuels *could* increase greenhouse gas emissions.The study, released last week in Science, claimed that production of corn ethanol and biodiesel could lead to forests and grasslands being converted to cropland in other parts of the world.
The two researchers, Michael Wang of the Argonne National Laboratory and Zia Haq of the Energy Department's biomass program, faulted the study for a number of reasons including current land use assumptions and failure to consider future crop yield increases.
