At a time of soaring food prices and concern over carbon emissions, George Bush needs to rethink his biofuel policy.
Just in time for today’s Earth Day festivities, President Bush has announced a new initiative to combat global warming. He set a goal of stopping the growth in greenhouse gas (GHG) emissions by 2025 and reducing emissions thereafter. But rather than plan for 2025—which is another two or three presidencies away—Bush should immediately fix his ethanol policy, which is increasing GHG emissions and raising food prices not only in the United States but all over the world.
American companies are still trying to digest the ethanol mandates passed by Congress last December. Congress mandated the production of 9 billion gallons of ethanol or other renewable fuels this year; that number will gradually increase until it reaches 36 billion gallons in 2022. In addition, ethanol producers receive a tax break of 51 cents a gallon, and corn growers receive huge subsidies that may increase in the next farm bill.
Using ethanol for energy was supposed to be a win-win situation: the United States has so much corn, we were told, that it could use some to make gasoline, thereby reducing its GHG emissions and also reducing its dependence on foreign oil. But in the real world, unintended consequences are all too frequent.
Take the linkage between ethanol and GHG emissions. Scientists now believe that the production of ethanol actually creates more harmful emissions than it prevents. Indeed, Princeton University professor Timothy Searchinger and other researchers have concluded that “corn-based ethanol, instead of producing a 20 percent savings, nearly doubles greenhouse emissions over 30 years and increases greenhouse gases for 167 years.†(Their findings were published earlier this year in Science magazine.) The reason is that converting undeveloped land to cropland—in order to grow more corn and facilitate biofuel production—releases a massive amount of carbon dioxide. Only if biofuels are made from waste products or grown on abandoned agricultural lands does the production process actually reduce GHG emissions.
