gallon of gas that is burned puts over 19 lbs of carbon dioxide out into
the air, experts say the number one way to reduce carbon emissions from
motor vehicles is to take steps to improve gas mileage. But there's a
Catch-22 for U.S. states that want to do something: Federal law basically
ties states' hands in tackling the problem by preventing states from directly
regulating gas mileage.
addition to preventing direct state regulation of gas mileage, federal
law also limits state regulation of the related issue of tailpipe emissions.
Under federal Clean Air law, states have only two auto emissions regulatory
options: They can adopt basic federal automobile tailpipe emissions standards;
can adopt the "clean car" program developed in California, which
is given special authority by federal law to set a higher emissions standard.
have more to gain financially from improved gas mileage under the California
Clean Car program than the states that have already adopted it. That's
because Southerners drive more than the national average, according to
U.S. Department of Transportation data. Because they drive more - and
spend more on gas - Southerners will save more money if their cars get
better gas mileage.

global warming, save money and reduce air toxics.

comes out of cars and trucks, it's common sense to try to cut some of

program allows states to set higher emissions standards, which cut down
on greenhouse gases. So far, 11 other states have adopted.

air emissions. Enough gasoline is saved in the first 11 states that

local governments can't directly impact emissions standards, they can
show leadership by buying hybrid and alternative fuel vehicles that
lower global warming emissions.
As this chart from Chapter
4 highlights, Southerners in every state but Louisiana drive more average
miles per capita than the U.S. average.
