Chart of the Day

Miller-McCune magazine points out today that we’ll soon have new CAFE fuel standards.  EPA and the Department of Transportation announced their proposed new rules on Tuesday, and in an effort to find something interesting to say about them I present you with this chart.

Normally, CAFE is a DOT program.  But the Supreme Court recently ruled that EPA was required to regulate greenhouse gases under the Clean Air Act, so now it’s a two-agency operation.  EPA’s part isn’t to directly regulate fuel economy, it’s to regulate CO2 — though this largely amounts to the same thing.  Basically, it works like this: you multiply a car’s track width by its wheelbase to come up with its “footprint” in square feet.  Then you go to this chart, which tells you how much CO2 it’s allowed to emit.  A subcompact, for example, will be allowed to emit no more than 204 grams of CO2 per mile in 2016.  (That’s what the technical appendix says, anyway.  The chart seems to be offset slightly high along its entire length.)

The Ninth Circuit Court has had problems with the whole “footprint” idea in the past, but EPA and DOT apparently hope that these new regs will pass judicial muster.  They also hope that car companies won’t just build bigger cars, thus doing an end run around the standards.  In fact, here’s what they hope the new rules will accomplish:

  • Increase fuel economy by approximately five percent every year
  • Reduce greenhouse gas emissions by nearly 950 million metric tons
  • Save the average car buyer more than $3000 in fuel costs
  • Conserve 1.8 billion barrels of oil

If the fooprint approach works the way it’s supposed to, we’ll reach a fleet average of 35 mpg by 2016 instead of 2020.  Time will tell.

THANK YOU.

We recently wrapped up the crowdfunding campaign for our ambitious Mother Jones Corruption Project, and it was a smashing success. About 10,364 readers pitched in with donations averaging $45, and together they contributed about $467,374 toward our $500,000 goal.

That's amazing. We still have donations from letters we sent in the mail coming back to us, so we're on pace to hit—if not exceed—that goal. Thank you so much. We'll keep you posted here as the project ramps up, and you can join the hundreds of readers who have alerted us to corruption to dig into.
