Gas Mileage: Why MPG Numbers Really Matter
(Page 4 of 5)
August/September 2007

Boosting CAFE standards has been a notoriously difficult sell in Washington. “It’s been a little bit like pushing a Chevy Suburban uphill with your nose,” says Dan Becker, director of the Sierra Club global warming program and an 18-year veteran of the CAFE struggle. That may be changing. Over the last few years, devastating hurricanes, Middle East instability and gasoline price spikes have brought oil back to the forefront of the national consciousness. At press time, there was new momentum in Congress for the notion of mandating better fuel economy, but the outcome was unclear at best. So the fight is far from over; voicing your opinion will help your representative understand the importance of this issue.

Ultimately, taking a personal interest in your fuel economy is one of the easiest and most important ways to make a difference. The more you pay attention, the more you’ll find yourself seeking ways to improve the results. Plus, it’s nice to reap the rewards of high mpg when gas prices are on the rise, as fuel-efficient vehicles offer “insurance” against volatility in the gasoline market. Yet regardless of whether gas prices level off or skyrocket to $5 a gallon, continued efforts to improve fuel economy will play an important role in mitigating global warming and our dependence on fossil fuels. So get that tuneup, check the tires, fill the tank, zero the trip meter and see how high you can push your mpg. It’s an open road, and you’re the driver.
