Not a novel concept. In DC you cannot sell or use gas powered leaf blowers because of the noise and air pollution. Electric are fine. There are also other counties in MD looking to impose similar regulations.

Imagine the government maintaining that you need mufflers or catalytic converters on your vehicle due to air and noise pollution...oh wait.

"A 2011 study showed that a leaf blower emits nearly 300 times the amount of air pollutants as a pickup truck. Similarly, a 2001 study showed that one hour using a gas-powered lawn mower is equivalent to driving a car 100 miles" https://sustainability.wustl.edu/rethinking-lawn-equipment-2/#:~:text=A%202011%20study%20showed%20that,driving%20a%20car%20100%20miles.
