A global overview of zero-emission zones in cities and their development progress
A zero-emission zone (ZEZ) is an area where only zero-emission vehicles (ZEVs), pedestrians, and cyclists are granted unrestricted access. Other vehicles are either prohibited from entering or permitted to enter upon payment of a fee. The growth of ZEZs could provide important support for the shift away from internal combustion engine vehicles, and this briefing provides a detailed overview of the cities that have implemented or have plans to implement ZEZs and variants. It also includes the progress each has made.
