City Carshare was founded as the first carsharing program in the San Francisco Bay area, and remains the only non-profit program in the metropolitan region. It provides its members with the use of fuel-efficient vehicles by the hour.

City CarShare was the only carsharing program in the San Francisco area from its founding in 2001 until 2005. The organization began with a fleet of 12 lime green Volkswagen Beetles and 850 members. The original pricing was a $300 deposit with a $10 monthly fee, in addition to fees of $2.50 per hour and 45 cents per mile driven. City CarShare expanded to include locations in Oakland, Berkeley, and Palo Alto in 2002. In 2004 City carshare began providing vehicles to the city of Berkeley, in order to help the city reduce emissions. The city sold off cars from its fleet in favor of using shared vehicles. By 2005 ABC 7 reported that the organization had saved more than one million gallons of gasoline since its founding, and the company saw a twenty percent rise in membership.[9] At this point, City CarShare was the largest non-profit car sharing program in the United States.

In 2006 University of California, Berkeley produced a study showing that City CarShare prevented nearly 25 million pounds of carbon emissions a year from entering the atmosphere. In 2011 City CarShare was one of eighteen organizations to form the North American CarSharing Association, the world's largest. City CarShare was one of the lead organizations in the new association, which had 100,000 members upon its launch. In 2011 City CarShare also partnered with the city of San Francisco to provide on-street parking exclusively for City CarShare vehicles.

The Clean Fleet Report has named City CarShare one of the ten best car-share programs in the United States, mentioning its focus on electric cars as one of the reasons behind this. The fleet was specifically implemented with Mitsubishi_i-MiEV electric vehicles. The use of electric vehicles in the fleet and around the city led the City of San Francisco to institute the installation of electric-vehicle charging stations in the downtown area. The company also runs the CommunityShare program for low income individuals and the AccessMobile program that provides wheelchair accessible vehicles.
