More than a dozen mayors from across California sent a letter to the California Air Resources Board (CARB) expressing their support for zero-emission transit buses and strong state action to accelerate deployment in their communities.
Representatives from the Union of Concerned Scientists (UCS) and the Advanced Clean Transit Coalition — a coalition of environmental, public health, science, labor and vehicle technology groups — presented the letter to CARB officials on Jan. 30, 2017. CARB is considering a new state regulation called the Innovative Clean Transit rule that would require zero-emission vehicles to make up at least 25% of transit agency bus purchases by 2020, and 100% of all new purchases by 2029.
“Not only can electric buses help California rise to meet our state’s public health challenges, but a swift transition to zero-emission buses will also help meet California’s goal of reducing greenhouse gas emissions to 40 percent below 1990 levels by 2030,” the mayors wrote. “A strong regulatory signal from CARB would spur increased production and competition, and continue to lower the purchase price of zero-emission buses.”

The heavy-duty transportation sector, which includes transit buses, freight trucks and delivery trucks, contributes a third of California’s smog-forming nitrogen oxides, the largest single source of this type of air pollution, and represents seven percent of California’s global warming emissions.
Compared to diesel and natural gas buses, battery powered electric buses on today’s grid in California emit 70% less global warming emissions, and hydrogen fuel cell electric buses emit 50% less emissions, according to UCS. Both battery powered electric and hydrogen fuel cell buses have no tailpipe pollution.
“Transportation electrification is among the best tools we have to fight climate change, and converting buses is the tip of the spear,” said Jimmy O’Dea, senior vehicles analyst at UCS. “Because they have similar components, if buses can electrify so can heavy-duty trucks.”

“The technology exists today to convert our bus fleets from fossil fuels to zero-emission technologies,” said O’Dea. “Last year’s decision by LA Metro, the second-largest bus fleet in the country, to electrify by 2030 added momentum to this statewide effort to reduce air pollution and defend against the worst impacts from climate change.”
The following California mayors, representing nearly eight million people, have signed the letter:
Mayor Jesse Arreguín, Berkeley Mayor Michael Brownrigg, Burlingame Mayor Mary Salas, Chula Vista Mayor Catherine Blakespear, Encinitas Mayor Rey León, Huron Mayor Serge Dedina, Imperial Beach Mayor R. Rex Parris, Lancaster Mayor Racquel Vasquez, Lemon Grove Mayor Robert García, Long Beach Mayor Eric Garcetti, Los Angeles Mayor Libby Schaaf, Oakland Mayor Darrell Steinberg, Sacramento Mayor Sam Liccardo, San José Mayor Helene Schneider, Santa Barbara Mayor Michael Tubbs, Stockton Mayor Erik Nasarenko, Ventura
Both Oakland Mayor Schaaf of Oakland and Imperial Beach Mayor Dedina represent cities that also filed lawsuits in state court last year against petroleum companies for climate change damages.
The beginning of the final BRT segment advances construction across all five segments, reflecting steady progress toward shorter travel times, improved accessibility, and a more dependable connection to jobs, businesses, and community destinations.
The visit is part of the SF Fed's ongoing engagement with major employers and industries across Southern California and, more broadly, the western U.S. to better understand regional economic conditions and business outlooks.
Advances in data and analytics are giving transit agencies new opportunities to refine maintenance practices, improve efficiency and make more informed decisions about asset performance.
Today’s riders—and the communities you serve—expect more from public transit. While ADA compliance is required, leading transit agencies know that true accessibility also means delivering dignity, efficiency, and a better rider experience. This whitepaper reveals why forward thinking agencies nationwide choose the Low Floor Frontrunner as their first choice for ADA compliant vehicles—setting a new standard with passenger first design, faster boarding, improved safety, and unmatched operational performance.
In Part 2 of a two-part conversation, AC Transit’s director of maintenance joins co-hosts Alex Roman and Mark Hollenbeck to discuss his maintenance team’s work with various types of vehicle, training, augmented reality, and more.
Under this extension, Keolis will continue to manage and operate fixed-route bus service across the East Valley, serving communities including Tempe, Mesa, Chandler, Scottsdale, the town of Gilbert, parts of Phoenix, and the Gila River Indian Community.
The new network reflects extensive input from riders and the community through Reimagine DART on what matters most in public transit — and those priorities are reflected in the changes ahead.
