Colorado Considers Ban on Gas-Powered Lawn Equipment Sales.

The Regional Air Quality Council in Colorado is considering a ban on the sale of gas-powered home lawn mowers, trimmers, and leaf blowers in metro Denver beginning in 2025 to combat severe ozone pollution. The most likely proposals would also ban summer use of existing gas-powered lawn equipment by big institutional users such as schools or parks and maintenance crews beginning in 2025, and by commercial users a year after that. Emissions from gas-powered lawn equipment make up a surprisingly high portion of chemicals that bake into summer ozone under Colorado’s hot sun.
