If you answer yes to that question, then you would be among a distinct minority, as Americans overwhelmingly oppose any sort of increased gas tax that would encourage them to drive more efficient vehicles.

The irony here is most people admit that we need to do something to reduce help reduce greenhouse-gas emissions, to reduce our dependence upon foreign oil, and to conserve fuel; yet aren't willing to put their money where their mouth is.

"With one-fifth of all U.S. CO2 emissions coming from light trucks and cars, any serious effort to significantly reduce U.S. emissions would have to encourage fuel conservation in personal automobiles," said David Ridenour, vice president of the National Center for Public Policy Research. "But almost half of all Americans oppose spending more for gasoline, despite polls indicating wide public concern over global warming. These results suggest Americans' concern may not be as deep as we've been led to believe."
