The new battery-electric bus fleet, manufactured by Proterra, will reduce Bay Area emissions and support SFO's goal of carbon neutrality by 2021 while cutting its bus operating costs.
As one of the fastest-growing major airports in the US, SFO has ambitious plans in place to reduce its carbon footprint.
Indeed, its Five-Year Strategic Plan sets goals of carbon neutrality across airport-controlled operations by 2021 and the reduction of greenhouse gas emissions by 50% from a 1990 baseline.
Part of that plan includes the creation of a Clean Vehicle Policy to promote the adoption and deployment of low emission vehicles by both airport departments and ground transportation providers.
The new battery-electric Proterra Catalyst buses will replace six diesel buses in its current operating fleet and will eliminate more than 23 million pounds of greenhouse gas tailpipe emissions over the 12-year life of the vehicles.
SFO expects to purchase additional battery-electric buses to replace its CNG vehicles, for a greener, more modern fleet.
"SFO is an airport industry leader in sustainability, and we have set big goals to achieve zero net energy use, zero waste, and carbon neutrality," says airport director Ivar Satero.
"By deploying San Francisco's first public battery-electric buses, we're on the path to zero emissions in our ground transportation services, leading the way in our quest to be the world's most sustainable airport."
The new electric buses will integrate batteries that are designed and manufactured down the street from the airport at Proterra's Silicon Valley headquarters in Burlingame, California.
With 44kw/h of battery capacity on board, the buses will be part of SFO's fleet that currently provides buses to shuttle passengers between the terminals, long-term parking garages and other airport locations along daily routes.
"San Francisco International Airport has long been a leader in sustainability and joins other forward-thinking airports around the country in transitioning ground fleets to 100% battery-electric buses," notes Proterra CEO, Ryan Popple.
"We are proud to help one of our local airports offer superior service and meet its sustainability goals while also providing reduced vehicle maintenance costs and lower total cost of ownership."
