"State regulations limiting gas-powered lawn equipment for public properties went into effect this month. Users are warming up to the cleaner, quieter tools." 

"CENTENNIAL, Colorado — At a grassy city park this spring, professional landscapers sauntered between vendor booths, asking questions about the shiny new wares laid out before them: battery-powered push mowers, leaf blowers, string trimmers, chainsaws, and more. Some hopped on new standing and riding mowers to give them a spin.

Noticeably absent throughout it all was the scent and the roar of gas-guzzling equipment; the tools were all electric.

At the event hosted by the nonprofits Regional Air Quality Council and the Colorado Public Interest Research Group Foundation, landscapers were scoping out battery-powered tools to prepare for statewide regulations that kicked in this month. The first-of-their-kind rules, adopted in 2024, restrict the use of landscaping equipment with small gasoline-powered engines on public property during the summer — the state’s high-ozone season.

As you might guess from just a whiff of the noxious fumes, gas-fueled lawn and garden equipment are extremely polluting. Their combustion engines are a hazard not only to a stable climate, but also human health."
