Supported by grants from U.S. Department of Energy and the California Energy Commission and with charging equipment donated to the city by Google, ownership, maintenance and operation will be handled by San Francisco Recreation and Park for the first 12 months of operation. It brings the department's network to 29 charging points.

City CarShare’s fleet, of which over half is made up of hybrid, plug-in hybrid and electric vehicles, includes the Ford C-Max Energi and Toyota Prius Plug-in Hybrids available in San Francisco.

Kezar Stadium has been home to five of the company’s vehicles since 2002, and now offers eight parking spaces for members. The fleet is claimed to be on track to reduce CO2 in the Bay Area by 2014, as part of ongoing plans to cut city-wide CO2 emissions by 40% by 2025.

This goal also includes supporting 50% of all trips being made by sustainable modes of transport – including walking or cycling.

Melanie Nutter, director of project partner the San Francisco Department of the Environment, said: ‘The newly installed chargers at Kezar Stadium are making electric vehicles available to a wider audience through City CarShare. The continued adoption of electric vehicle infrastructure is key to helping meet our City’s greenhouse gas reduction goals.’
