They probably weren't too concerned with the emissions from the leaf blowers themselves, but the dust and whatnot they whip up into the air.

Most gas-powered leaf blowers use two-cycle engines, which produce hundreds of times more hazardous pollutants and fine particulates than cars. Leaf blowers overtook automobiles as the number one source of air pollution in California during 2020.

I did want to kneecap the idiot that decided to use a leaf blower to blow the sand off the parking lot of the apartment I used to rent in. Was kind of tempted to send the manager a bill for a new clear coat on my car.
