On the road
Pump up tires
"If you'd properly inflate your tires, you could reduce global warming and have cleaner air to breath," says Savannah Waters, who founded Pump 'Em Up at age 9. She makes a good point. If all American drivers kept their tires at the recommended pressure, we'd save about 4 million gallons of gas a day (and our tires would last longer, too).
Drive smart
When waiting to pick up kids after school or soccer practice, you'll spare the air — and the lungs of the children waiting for their rides — if you don't let your car idle. The Environmental Protection Agency recommends turning off your engine if you're going to be in one place for more than 30 seconds.
Also, be a steady driver. By avoiding sudden braking and acceleration, you'll increase fuel efficiency by as much as 40 percent. And if you set your highway cruising speed to 55 to 60 miles per hour, you'll save even more gas.
"Driving the speed limit and at a steady speed, without sudden stops and starts, is safer for you and your children anyway," Jennifer Hattam points out.
Plan your trip (or just walk)
Given that roughly a quarter of daily car trips are one mile or less, there's a health-friendly alternative way to get to the local market or park. "Get out of your car," says Rachelle Carson-Begley. "Walk a little and get your exercise." And when you do climb into your car, plan your trip so you hit all your stops along the most efficient route — you'll save time, money, and gas.
