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

The document outlines the role of EV carshare in addressing urban mobility, affordability, and air quality. It compares three primary business models—cooperative, for-profit, and nonprofit—and details operational considerations such as site selection, reservation structures, and the critical challenge of insurance. It highlights the potential for EV carshare to reduce private vehicle ownership and development costs, citing a specific example from Austin, Texas, where parking requirement reductions saved $38.5 million in housing costs. The guide emphasizes the need for strategic partnerships, diversified revenue streams, and iterative program design to ensure long-term financial viability and equitable access.

• EV carshare can significantly reduce the need for private parking and lower housing development costs. 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) eliminated 1,100 parking spaces and saved $38.5 million in development costs over three years.
• Different business models offer varying trade-offs between community goals and financial stability: cooperative models prioritize local control and resident needs but struggle with capital and maintenance; for-profit models offer operational efficiency and technology but may neglect disadvantaged communities; and nonprofit models align closely with equity goals but often depend on external funding.
• The choice of service model affects the program's impact on private car ownership. Round-trip station-based models, which require users to return vehicles to the original site, are more effective at reducing private auto ownership than free-floating models because they encourage planned use over spontaneous trips.
• Strategic program design, including the use of shared EVs to replace gas-powered vehicle miles, can lead to substantial environmental gains. For example, the BlueLA program in Los Angeles County reduced community vehicle miles traveled (VMT) by 34% and greenhouse gas emissions by 48%.
• Insurance represents a critical barrier to entry for EV carshare providers, particularly for small or nonprofit operators. 75% of providers interviewed by RMI identified insurance as a "make-or-break issue," with some experiencing a 300% price increase in 2025 for a fleet of 15 vehicles.
• The financial requirements for launching and maintaining EV carshare are significant. Adding a used EV costs at least $20,000, while a new EV costs at least $30,000. Monthly operating costs, including insurance, maintenance, and staff, typically range from $1,500 to $2,000 per vehicle.
