Colorado Regulators Float Metro Denver Sales and Use Ban on Gas Lawn Equipment Beginning 2025
Draft policies circulating at Colorado's Regional Air Quality Council would ban sales of gas-powered lawn mowers, trimmers, and leaf blowers in metro Denver starting in 2025, with summer-use bans for institutional and commercial users to follow. The proposals target ozone pollution on the northern Front Range and are expected to reach a formal vote before the Air Quality Control Commission later in 2023. Environmental groups like CoPIRG are supportive; a state legislative bill for a 30% rebate on electric lawn equipment is also in progress.
