Driving Electric: Designing EV Carshare to Expand Access to Affordable, Reliable, Clean Transportation

This guide by RMI provides best practices for cities and local partners to design and implement electric vehicle (EV) carshare programs. It outlines various business models—cooperative, for-profit, and nonprofit—and discusses the strategic importance of site selection, partnership development, and policy support to balance financial sustainability with equitable mobility and environmental goals.

• EV carshare can significantly reduce the need for private vehicle ownership and the associated public space requirements. On average, one carshare vehicle can replace fifteen privately owned vehicles. In Austin, Texas, a policy allowing on-site carshare vehicles to reduce off-street parking requirements by up to 40% (20 spaces per shared vehicle) resulted in the elimination of 1,100 parking spaces and $38.5 million in housing development cost savings over three years.
• The guide identifies three primary business models for EV carshare, each with distinct trade-offs: cooperative models prioritize local control and community needs but struggle with capital and operational speed; for-profit models offer high operational efficiency and technology but may neglect disadvantaged areas to ensure profitability; and nonprofit models align closely with equity goals but often depend on external philanthropic or public funding for viability.
• Strategic program design, particularly regarding reservation systems and siting, impacts environmental outcomes. For example, the BlueLA EV carshare program in Los Angeles County reduced community vehicle miles traveled (VMT) by 34% and greenhouse gas emissions by 48%. To maximize utilization and connectivity, vehicles should be placed in visible, mixed-use locations such as transit hubs, employment centers, and grocery stores.
• Insurance represents a critical barrier to the establishment and scaling of EV carshare programs, particularly for smaller or nonprofit operators. RMI found that 75% of interviewed providers viewed insurance as a "make-or-break issue," noting that many insurers refuse to work with small fleets or nonprofits. One provider reported a 300% insurance price increase in 2025 for a fleet of 15 vehicles.
• The financial requirements for launching EV carshare include significant procurement and operating costs. Adding a used EV to a fleet costs at least $20,000, while a new EV costs at least $30,000. Monthly operating expenses, including maintenance, insurance, and staff oversight, typically range between $1,500 and $2,000 per vehicle.
• To ensure long-term viability, cities should implement supportive policies and diversified revenue streams. Recommended policies include providing dedicated curb space, waiving parking fees, and streamlining charger permitting. Revenue can be diversified by placing vehicles in high-density commercial areas to cross-subsidize less-used sites, selling advertising on vehicles, or integrating carshare into municipal staff operations.
