Transportation Program

Over two-thirds of California's air pollution comes from mobile sources such as cars, trucks, buses, planes and marine vessels. For this reason the Coalition for Clean Air spends much of its time advocating for more stringent controls on vehicle emissions and the development and implementation of cleaner transportation using electric, hybrid, and hydrogen technology.

CCA is one of the leading environmental groups in California advocating for a transition away from petroleum-based fuels to cleaner alternatives. Our efforts include education on the health hazards associated with diesel exhaust, advocacy for regulatory reform by local, state and federal agencies, and promotion of incentives for the development and purchase of cleaner technologies.

We sponsored landmark global warming legislation in 2002 that will allow California to be the first state to directly regulate vehicle emissions that contribute to climate change. AB 1493, carried by Assembly Member Fran Pavley, (D-Agoura Hills), directs California's Air Resources Board to develop regulations that would achieve the maximum feasible reductions of greenhouse gas emissions from vehicles sold beginning in 2009. We continue to work hard to ensure successful implementation of the law.

One of our current campaigns is focused on the enormous amounts of pollution created at marine ports. The ports of Los Angeles and Long Beach are the largest fixed source of air pollution in the South Coast Air Basin, with especially high levels of air toxics derived from diesel sources.

A container ship that idles at dock emits roughly the amount of diesel pollution as a diesel truck would traveling 70,000 miles - the approximate distance of three trips around our planet. For every 24 hour period a ship sits idle at our docks unloading cargo, its engines can release more than one ton of smog-forming compounds into our region's air.

We also focus on other major sources of diesel, such as distribution centers, airports and rail yard facilities. For more details on the impact diesel has on our air quality, download one of our reports.
