Walnut Creek has banned gas-powered leaf blowers.

Noise is the obvious pollutant that many focus on, but emissions from 2-stroke engines are startlingly toxic, including a mix of:

- Carcinogens (benzene, PAHs)
- Lung irritants (PM2.5, NOx)
- Toxic gases (CO)
- Smog-forming chemicals (VOCs, hydrocarbons)

Best is not to use leaf blowers at all (they lift topsoil into the air), but battery is orders of magnitude less harmful.

Ban on gas-powered leaf blowers takes effect in Walnut Creek

As of April 1, people found using gas powered leaf blowers could be fined $100 for their first infraction, $200 for the second and $500 for each following infraction.

@mmalc Los Altos has banned them as well. So I've seen 2-person teams walking around. One operating an electric leaf blower, and a second person trailing them with a gas-powered generator that the leaf blower is plugged in to.

Of course, that largely defeats the point, but from the perspective of pollutants it's actually a significant improvement — emissions from a mostly steady-state 4-stroke engine (generator) are generally (much) lower than the 2-stroke engine.

This is especially true for hydrocarbons where the 2-stroke basically jets out about a third of its fuel unburned. The generator probably emits more NOx.
