"Cash For Clunkers" Does Little To Help The Environment

(CBS)
This was, after all, one of the primary justifications that the Obama administration offered for the program. "This gives consumers a break, reduces dangerous carbon pollution and our dependence on foreign oil, and strengthens the American auto industry," President Obama said last month.
Other Democrats have touted the idea as a way to reduce CO2 emissions. Rep. John Dingell of Michigan predicted in June that the legislation "will result in meaningful reductions in vehicle fleet carbon emissions and fuel consumption." And to Rep. John Olver from Massachusetts, cash-for-clunkers will "pave the way toward a lower-carbon future." Time magazine already is calling the program a "green success."
That argument has a visceral appeal: Let's take the cash for our old cars and trucks, get new ones with Bluetooth and iPod connections, and help out the environment in the process. But a closer look at the existing $1 billion cash-for-clunkers program shows that the rhetoric of Washington politicians doesn't match reality.
Some simple calculations suggest that the existing program will save only about 365,000 metric tons of CO2 a year. Compare that to 29,028,000,000 tons of CO2 emitted worldwide every year, according to U.S. government estimates.
