Abstract:

This briefing reviews the latest literature on the benefits of and opportunities for faster zero-emission vehicle (ZEV) transitions within fleets, and highlights the role of governments in supporting these transitions. The authors define fleets broadly to include a variety of vehicles used for commercial and public purposes—company cars, taxis, vans, delivery and ride-hailing vehicles, two- and three-wheelers, trucks, and buses—that are owned or operated by either governments, businesses, or individuals. Under this definition, vehicle fleets currently make up a quarter of vehicles on the road and almost two-thirds of greenhouse gas emissions from road transport globally.
