Electrifying carshare and ride-hail services is a promising way to reduce greenhouse gas emissions from the transportation sector and help government achieve their climate change goals, according to recent literature. In addition, research shows better economics for ride-hail drivers could exist when the cost of charging is less than gasoline, and when charging is available and fast enough to not cut into their driving time. However, there remains an open question of if and how much carsharing and ride-hailing services can reduce travel overall, and therefore, greenhouse gas emissions. The barriers and solutions to deploying electric vehicles in shared mobility services is largely similar to those faced in the personal vehicle market. This state of play of shared mobility in the United States and literature review is a part of Making the Business Case for Smart, Shared, and Sustainable Mobility, a project which aims to accelerate the adoption of electric vehicles in shared mobility services and to establish best practices that can be used by others around the United States.
