A Spare the Air Alert is in effect, Friday, September 13, for the San Francisco Bay Area.
Concentrations of ground-level ozone pollution are forecast to be unhealthy. High levels of ozone pollution are harmful to breathe, especially for young children, seniors and those with respiratory and heart conditions.
Exhaust from vehicles on Bay Area roads accounts for more than half of the air pollution in the region. Bay Area residents are asked to drive less to reduce smog and improve air quality in the region. Residents are also encouraged to consider an all-electric vehicle as their next vehicle purchase to help reduce the amount of gas powered vehicles that contribute to unhealthy smog.
Change your daily commute by carpooling, vanpooling, taking transit, biking or walking instead of driving alone. Doing this will help reduce pollution levels and health concerns when temperatures are high. To learn how to change your commute online, visit 511.org.
