Leaf blowers are being banned primarily because of noise and air pollution — gas-powered models produce emissions exceeding those of passenger cars at highway speed, and sound levels that routinely hit 85–95 dB at the operator's ear.
Most bans target gas-powered leaf blowers specifically, not cordless or electric alternatives. California led the wave with a 2024 ban on the sale of new small off-road gas engines, including leaf blowers, citing smog-forming hydrocarbon emissions. Cities like Washington D.C. and dozens of municipalities have added local restrictions focused on noise, typically setting limits during early morning or evening hours or prohibiting gas blowers outright in residential zones. The policy pressure is accelerating as cordless tools become more capable.
- Gas leaf blowers can emit more smog-forming pollution per hour than a 2017 Toyota Camry driven 1,100 miles.
- California banned sales of new gas-powered leaf blowers statewide, effective January 1, 2024.
- Typical gas leaf blower noise: 85–95 dB at operator distance, above OSHA's 85 dB action threshold.
- Over 100 U.S. cities have passed some form of gas or noise-based leaf blower restriction as of 2024.
- Most local bans exempt battery-powered and corded electric leaf blowers from restrictions.
