Study Claims Biofuels' Emissions Worse That Gasoline

Princeton economist Tim Searchinger has become a major critic of biofuels. He argues that there is no gain in carbon emissions because the land was lying fallow and pulling carbon into long-term storage.  Thus, the argument that biofuels are “carbon neutral” because they pull the same amount of carbon out of the air as they put back is a form of double counting. It doesn’t consider what the land was being used for before it was put into raising biofuels. If land already under cultivation is used, then that land will have to be replaced by other land somewhere else, which robs the new land of its storage value. Much forest land is being cut down to grow biofuels, for instance, which obviously reduces its ability to store carbon. The graph shows the difference. If biofuels are considered on a purely theoretical basis, they produce an emissions reduction. But once we consider the amount of new lands that must be put into cultivation, the emissions count is much higher than gasoline.
