Diesel Bus Phase-Out

On March 2, 2004 two-thirds of San Francisco voters approved Proposition I to take strong steps toward cleaning up the city’s air. MUNI is now phasing out its 100 most polluting diesel buses.

Prop I set a clear timetable for retiring the old diesels and requires MUNI to replace them with new buses that meet the same modern pollution standards as other city vehicles.

Now the city is gaining a cleaner, quieter and more reliable public transportation system. And the resulting reduction in diesel emissions will reduce public health expenses and other costs of air pollution.

Our City played a key role in spreading the word about Prop I. Our field team passed out voter information to households throughout the city, and Our City volunteers took time out of their busy schedules in the weeks before the election, to make sure as many voters as possible knew about Prop I.

Thanks to all who played such an important role in passing this measure to clean up our air!
