Did you know . . . ?

Gas-powered yard equipment causes more than 10 percent of summertime smog.

Here's how you can help reduce this pollution:

Choose a non-polluting electric lawnmower.
When summer smog levels rise, wait to use gas-powered yard equipment until air quality improves -- or switch to electric equipment.
Cut down on the amount of lawn you have in your yard to reduce mowing and the air pollution it causes.
Plant trees and shrubs in areas where they can help improve energy efficiency by providing shade in summer and blocking wind in winter.
