Spectators at
February’s Daytona 500 in Florida were handed green flags to wave in
celebration of the news that the race’s stock cars now use gasoline with 15%
corn-based ethanol. It was the start of a season-long television marketing
campaign to sell the merits of biofuel to Americans.
On the surface, the self-proclaimed
“greening of NASCAR” (National Association for Stock Car Auto Racing) is merely
a transparent (and, one suspects, ill-fated) exercise in an environmental form
of whitewashing for the sport – call it “greenwashing.” But the partnership
between a beloved American pastime and the biofuel lobby also marks the latest
attempt to sway public opinion in favor of a truly irresponsible policy.
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 US and Europe, including aggressive production
targets, biofuel consumed more than 6.5% of global grain output and 8% of the
world’s vegetable oil in 2010, up from 2% 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%.
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. Even former US Vice President and
Nobel laureate Al Gore – who once boasted of casting the deciding vote for
ethanol support – calls the policy “a mistake.” He now admits that he supported
it because he “had a certain fondness for the [corn] farmers in the state of
Iowa” – who, not coincidentally, were crucial to his 2000 presidential bid.
It is refreshing that Gore has now changed
his view in line with the evidence. But there is a wider lesson. A chorus of
voices from the left and right argue against continued government support for
biofuel. The problem, as Gore has put it, is that “it’s hard once such a
program is put in place to deal with the lobbies that keep it going.”
Politicians can’t stop such rent-seeking
behavior. What they can do is craft well-considered policies that maximize
social welfare. Unfortunately, when it comes to policies marketed as reining in
global warming, protecting the environment, or creating “green jobs,” we have a
tendency to make hasty decisions that don’t pass the test.
Government support for biofuel is only one
example of a knee-jerk “green” policy that creates lucrative opportunities for
a self-interested group of businesses but does very little to help the planet.
Consider the financial support afforded early-generation renewable-energy
companies. Germany led the world in putting up solar panels, funded by $75
billion in subsidies. The result? Inefficient, uncompetitive solar technology
sitting on rooftops in a fairly cloudy country, delivering a trivial 0.1% of
Germany’s total energy supply, and postponing the effects of global warming by
seven hours in 2100.
Given the financial stakes, it is little
wonder that alternative-energy companies, “green” investment firms, and biofuel
producers are lobbying hard for more government largesse, and marketing their
cause directly to the public by highlighting its supposed benefits for the
environment, energy security, and even employment – none of which withstand
scrutiny. “The NASCAR deal will push American ethanol into the stratosphere,”
declared Tom Buis, CEO of the ethanol trade association Growth Energy.
At least one group is already sold:
presidential contenders. In Iowa last month, possible Republican candidate Newt
Gingrich derided “big-city attacks” on ethanol subsidies. And, in what must be
music to the industry’s ears, an Obama administration official declared that
even amidst the highest food prices the world has seen, there is “no reason to
take the foot off the gas” on biofuel.
In fact, there are millions of reasons –
all of them suffering needlessly – to apply the brakes.
