Bjørn Lomborg:
The United States spends about $6 billion a year on federal support for ethanol production through tax credits, tariffs, and other programs. Thanks to this financial assistance, one-sixth of the world's corn supply is burned in American cars. That is enough corn to feed 350 million people for an entire year.
Government support of rapid growth in biofuel production has contributed to disarray in food production. Indeed, as a result of official policy in the United States and Europe, including aggressive production targets, biofuel consumed more than 6.5 percent of global grain output and 8 percent of the world's vegetable oil in 2010, up from 2 percent of grain supplies and virtually no vegetable oil in 2004.
This year, after a particularly bad growing season, we see the results. Global food prices are the highest they have been since the United Nations started tracking them in 1990, pushed up largely by increases in the cost of corn. Despite the strides made recently against malnutrition, millions more people will be undernourished than would have been the case in the absence of official support for biofuels.
We have been here before. In 2007 and 2008, the swift increase in biofuel production caused a food crisis that incited political instability and fueled malnutrition. Developed countries did not learn. Since 2008, ethanol production has increased by 33 percent.
Biofuels were initially championed by environmental campaigners as a silver bullet against global warming. They started to change their minds as a stream of research showed that biofuels from most food crops did not significantly reduce greenhouse gas emissions – and in many cases, caused forests to be destroyed to grow more food, creating more net carbon-dioxide emissions than fossil fuels.
Some green activists supported mandates for biofuel, hoping they would pave the way for next-generation ethanol, which would use non-food plants. That has not happened.
Today, it is difficult to find a single environmentalist who still backs the policy. ...
