What’s the Most Polluting Car?


suv.jpgForbes.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.

DOES IT FEEL LIKE POLITICS IS AT A BREAKING POINT?

Headshot of Editor in Chief of Mother Jones, Clara Jeffery

It sure feels that way to me, and here at Mother Jones, we’ve been thinking a lot about what journalism needs to do differently, and how we can have the biggest impact.

We kept coming back to one word: corruption. Democracy and the rule of law being undermined by those with wealth and power for their own gain. So we're launching an ambitious Mother Jones Corruption Project to do deep, time-intensive reporting on systemic corruption, and asking the MoJo community to help crowdfund it.

We aim to hire, build a team, and give them the time and space needed to understand how we got here and how we might get out. We want to dig into the forces and decisions that have allowed massive conflicts of interest, influence peddling, and win-at-all-costs politics to flourish.

It's unlike anything we've done, and we have seed funding to get started, but we're looking to raise $500,000 from readers by July when we'll be making key budgeting decisions—and the more resources we have by then, the deeper we can dig. If our plan sounds good to you, please help kickstart it with a tax-deductible donation today.

Thanks for reading—whether or not you can pitch in today, or ever, I'm glad you're with us.
