Does your work involve improving the environment or traffic in your city or ministry?
Are you operating, planning, considering, investigating a Low Emission Zone, Congestion Charging, urban road user charging, access regulation, vehicle access restriction, lorry ban etc?
Then the CLARS Platform is for you.

If you want to tell us about a scheme in your city, please see the bottom of this page.

The EU Commission has provided FREE membership for the CLARS Platform (Charging, Low Emission Zones, other Access Regulation Schemes) to help support public authorities with these schemes, as well as provide a public website to provide vehicle drivers and operators with information on the schemes.
This Platform allows best practice to be shared, to make schemes more successful and easier to implement. If you are planning a scheme, you do not need to re-invent the wheel.

The FREE Membership provides access to:

3) A forum to ask questions, discuss issues, post information
4) Period emails with news, updates and issues
5) The EU is considering producing guidance for LEZs and urban road charging. If so, CLARS would be used for the informal consultation before introducing it.
