A gasoline-powered leaf blower emits as much pollution hourly as a car driven 100 miles. On Spare The Air days, try biking, walking, telecommuting, taking public transit or carpooling with a fried. Motor vehicles emit more than 50 percent of the ozone-forming compounds and over 70 percent of the carbon monoxide in the Bay Area. Automobiles are now the single largest sources of air pollution.

Most of these products, such as hair sprays, deodorants, and pesticides, are also manufactured in pump, solid or roll-on forms. Choose these non-aerosol forms instead. Aerosol spray products send more than 27 tons of pollution into the air we breathe every day. Close to one half of that comes from hair spray alone.
