In an effort to improve air quality and mitigate climate change impact, Boulder County Public Health and the Regional Air Quality Council are inviting the public to swap gas-powered lawn mowers for electric lawn mowers.

On June 3 at the Mow Down Pollution event, people can exchange gas-powered lawn mowers and receive a discount of up to $200 on new electric models, or purchase an electric lawn mower from 8 a.m. to 2 p.m. at Eco-Cycle, 6400 Arapahoe Ave. in Boulder.

According to a Boulder County Public Health news release, gas-powered lawn mowers and gardening equipment contribute to about 10 percent of emissions creating poor air quality in the Denver metro region.

The emissions created by chemical reactions — triggered by mowing lawns, driving, painting, fueling vehicles and using solvents — in the presence of sunlight form ground-level ozone.

For every electric lawn mower used in place of a gas-powered one, according to the Regional Air Quality Council, approximately 49 pounds of ozone-generating emissions and 101 pounds of carbon monoxide are kept out of the air.
