A vote could come today on a bill designed to offer credits of up to $4,500 for consumers to trade-in gas-guzzling older vehicles. The so-called "cash for clunkers" legislation is designed to stimulate auto sales, but it also stands to effectively remove gross polluters from the roads and put drivers in safer and more fuel efficient vehicles.

As you would expect, the legislation is supported by automakers and dealers – both consider the program crucial to helping them weather the current sales environment. President Barack Obama has urged Congress to pass such a bill, and the Alliance of Automobile Manufacturers has also petitioned in its favor. Similar "cash for clunkers" programs have already proven effective in many other countries. About the only thing standing in the way of this bill appears to be a competing measure, proposed by Sen. Dianne Feinstein (D-Calif.), that appears to prioritize environmental goals over automotive sales.
