Forbes.com has published a list of the ten dirtiest cars. Or more accurately—vehicles, since all but a few are SUVs and trucks. (And surprise! The Hummer isn't number one).
The list order is mostly based on the EPA's air pollution rankings, but to break ties, Forbes.com also took into account vehicles' carbon footprints. The nadir of the coverage is in their "Tips for Polluting Less":
Experts say that realizing even minor improvements in fuel economy among the worst polluters on the road is the most efficient way to reduce greenhouse gas emissions overall. For example, choosing a base GMC Yukon with a 5.3-liter V8, which gets 16 mpg overall, instead of the high-end Denali version and its 14-mpg 6.2-liter V8 would save more than 130 gallons of gasoline per year for the typical driver, and eliminate 1.7 tons of carbon dioxide emissions, says Therese Langer, transportation program director for the American Council for an Energy-Efficient Economy.
Langer then goes on to say that "achieving the same savings through improvements to a 42-mpg Honda Civic Hybrid would require a 25-mpg boost, to 67 mpg."
So let's get this straight: Consumers should feel good about choosing a Yukon SUV over a hybrid, since the Yukon is way more efficient than the Denali? That's kind of like trying to lose weight by eating a ho-ho instead of a ding-dong.
Full top ten list after the jump.
