SF Muni Leads North America in Green Fleet
SFMTA highlights Muni's 100% renewable hydropower fleet and battery-electric bus pilot program
SFMTA Marks Earth Day With Green Transit Push
San Francisco's Muni operates the greenest fleet of any major North American transit agency, officials said Tuesday as the system marks Earth Day on April 22. The San Francisco Municipal Transportation Agency is highlighting its trolley buses, Metro trains, cable cars, and streetcars that run on 100% renewable hydropower from the Hetch Hetchy Power System. The agency's working to phase out all remaining diesel and gas-powered vehicles through a battery-electric bus pilot program.
Context
The transit initiatives support San Francisco's goal to achieve net-zero carbon emissions by 2040, according to the agency. SFMTA's environmental efforts extend beyond vehicle electrification to include street safety improvements that encourage residents to choose walking, rolling, or public transit instead of driving. The agency said its multi-pronged approach addresses both climate goals and urban livability. Transit officials said the renewable hydropower system gives San Francisco a significant advantage in reducing transportation emissions compared to other major cities.
Safety Improvements
In the final quarter of 2025, SFMTA installed 88 new speed humps, 33 high-visibility crosswalks, and 11 pedestrian safety zones to improve street safety for pedestrians and cyclists. The Muni Forward initiative has resulted in more than 48 miles of safety improvements, with injury collisions falling by 50% or more on multiple corridors and travel times up to 35% faster. The agency has achieved record-high rider satisfaction ratings due to these improvements. Speed Safety Camera networks are being used to encourage drivers to slow down, with violation revenues dedicated to further street safety improvements.
Charging Network Expansion
SFMTA is expanding San Francisco's curbside electric charging network in partnership with City Hall and the private sector to make electric vehicle ownership easier, officials said. The expansion aims to support the city's broader transition away from fossil fuel-powered transportation. Officials didn't provide specific numbers for how many charging stations will be added or a timeline for the network expansion. The agency said the charging infrastructure complements its public transit investments by supporting residents who need personal vehicles.
Rider Impact
Transit riders can expect continued service on the fully electrified trolley bus, Metro, cable car, and streetcar lines that already run on renewable power. The agency encourages residents to choose public transit, walking, or rolling instead of driving to help meet environmental goals. Officials said the combination of green fleet operations, improved safety infrastructure, and faster travel times makes Muni an increasingly attractive option for San Francisco commuters. Moovit provides real-time updates and trip planning for all SFMTA routes throughout the Bay Area.
