The article by Stuart Silverstein and Anne Boiko-Weyrauch discusses the pollution and health risks from gas-powered leaf blowers, highlighting emissions of toxic substances like benzene and ultrafine particles that pose serious health risks, particularly to landscaping workers. Jamie Banks, founder of Quiet Communities, is mentioned for advocating against noise and emissions from such equipment. Efforts to switch to electric equipment are growing, supported by incentives in some regions to promote cleaner alternatives.

Small off-road engines (SORE), used primarily for lawn, garden, and other equipment, have a population in California comparable to that of passenger cars. Despite making up only 8% of SORE, commercial lawn equipment accounts for 20% of smog emissions during summer. Running a commercial mower for an hour emits pollution equal to driving a new car 300 miles, while a leaf blower equates to 1,100 miles. The California Air Resources Board (CARB) has significantly reduced SORE emissions since 1990 but projects that by 2031, SORE emissions will double those of passenger cars. To address this, CARB aims for zero emissions from off-road equipment by 2035, with new standards and incentives in development.
