San Francisco's Spare the Air campaign encourages commuters to carpool, use public transit or ride bikes to work. The idea is to get people to reduce the amount of time they spend driving to work alone, thereby taking more vehicles off the roadways and reducing air pollution.
The San Francisco Bay Area has a number of public transportation options, including bus, ferry and train service. A link to 511 Trip Planner allows people to find the best transit options for their destinations, locates ride share lots, provides traffic information and advises on bike routes.
Clicking on the Bicycling tab opens a link to Bay Area Bike Share, a service that rents bikes 24/7 at designated locations. As of 2015, the fast-growing service provides rentals in San Francisco, Redwood City, Mountain View, Palo Alto and San Jose.
The Spare the Air website, SpareTheAir.org, provides an air quality forecast for different parts of the Bay Area and posts Spare the Air alerts. Residents can sign up to receive alerts by email and/or on their mobile devices. Downloadable apps are available. On alert days, residents are asked to make a special effort to get out of their cars and to avoid burning material of any kind.
Companies in the area that have at least 50 employers are required to register with the Bay Area Commuter Benefits Program, another part of the Spare the Air campaign that offers incentives to employees that participate in alternative transportation options.
