San Francisco International Airport (SFO) has purchased six Proterra Catalyst E2 e-buses and three 60 kW Proterra plug-in chargers. SFO says the e-bus fleet will help it reduce operating costs, and supports the airport’s goal of carbon neutrality by 2021.

The e-buses will replace six diesel buses in SFO’s current fleet. The buses, each of which includes 440 kWh of battery capacity, will be part of SFO’s fleet that shuttles passengers between terminals, long-term parking garages and other airport locations.

SFO says the e-buses will eliminate more than 23 million pounds of greenhouse gas tailpipe emissions over the 12-year life of the vehicles. In the future, the airport plans to add additional e-buses to replace its existing CNG vehicles.

With the purchase, SFO joins other California airports that are electrifying their transportation fleets, including Sacramento International Airport and nearby San José International Airport.

SFO Director Ivar C. Satero said, “We have set big goals to achieve zero net energy use, zero waste, and carbon neutrality. By deploying San Francisco’s first public battery-electric buses, we’re on the path to zero emissions in our ground transportation services.”
