The Environmental Protection Agency (EPA) calculates that a single gas lawn mower emits the same amount of volatile organic compounds in an hour as a car driven 350 miles. Multiply that times 54 million—the estimated number of Americans who mow their lawns every weekend—and it’s a staggering amount of toxic particles entering the atmosphere—some five percent of the nation’s total air pollutants. And because lawn mowers are used predominantly in hot months when ground-level ozone is the highest, they bring added misery to asthma sufferers.

 The EPA says that homeowners spill 17 million gallons of gasoline when refilling their lawn products, six million more gallons than the Exxon Valdez spilled into Prince William Sound in 1989.
