The CLARS Platform, an EU-funded scheme supporting public authorities to develop urban access regulation schemes, has a public website that provides information for vehicle operators on existing and confirmed Low Emission Zones (LEZs) and urban road-charging schemes in Europe, as well as most other access regulations. 

A map helps users search for individual European cities and see which LEZs, Urban Charging Schemes and Major Access Regulations are active in those cities. The website also includes explanations of different regulations and a guide to relevant EU policy.

To access the map, visit the Urban Access Regulations website.
