Calculations by The Associated Press, using Department of Transportation figures, show that replacing those fuel hogs will reduce carbon dioxide emissions by just under 700,000 tons a year. While that may sound impressive, it's nothing compared to what the U.S. spewed last year: nearly 6.4 billion tons (and that was down from previous years).
That means on average, every hour, America emits 728,000 tons of carbon dioxide. The total savings per year from cash for clunkers translates to about 57 minutes of America's output of the chief greenhouse gas.
Likewise, America will be using nearly 72 million fewer gallons of gasoline a year because of the program, based on the first quarter-million vehicles replaced. U.S. drivers go through that amount of gas every 4 1/2 hours, according to the Department of Energy.
For individuals, the program scores big. Vehicle owners who trade in an older, gas-guzzling truck or car for a newer fuel-efficient vehicle can get $3,500 to $4,500 in rebates. On average each year, they will save 287 gallons of gas, more than $700 in fuel costs and close to 3 tons in carbon dioxide pollution.
The problem is, there aren't enough of these individuals to dent the national or global energy and environmental problems.

So we know that the Cash 4 Clunkers program has been a nightmare for dealers and a tool used to destroy what would otherwise be good, reliable used cars for the lower and middle classes. Now, as was obvious to some, the AP is reporting that climatologists see the program having what amounts to no effect at all on emissions:
