This case study focuses on the City of Cincinnati, Ohio’s purchase of three all-electric fleet vehicles, a first for the municipality, and their plans to purchase 20 total in 2020. In the study, we look at the groundwork and factors that eventually led to the City completing its first procurement of EVs through the Climate Mayors Electric Vehicle Purchasing Collaborative. The Collaborative is a joint effort by Climate Mayors, the Electrification Coalition, and Sourcewell to accelerate city fleets’ transition to electric vehicles (EVs). By creating a new and innovative cooperative purchasing mechanism, the Collaborative is reducing major barriers to fleet electrification for cities and other public agencies.
