What we provide on Access Regulations for cities
Access Regulations are an increasingly important urban tool, for congestion, air pollution, noise and life quality. They can also help towards the EU goal of no conventionally fuelled vehicles in cities by 2050 and no conventionally fuelled logistics in 2030; as well as the EU air quality Limit Values.

CLARS (Charging, Low Emission Zones, other Access Regulation Schemes) membership supports public authorities with Access Regulations.

We also provide a key resource for the public, providing a comprehensive, neutral, single information source of Urban Access Regulations on the web, with all the information vehicle drivers and operators need. For cities, the public website provides a key part of your information dissemination for your Freedom of Movement responsibilities.

We provide best practice and experience of other cities to make schemes more successful and easier to implement.

The FREE CLARS Public Authority Membership provides access to:
1) A wealth of relevant information, guidance, advice, links and more
2) Periodic emails with ARS-focused news, updates and issues you should be aware of.
4) Looking to have ARS in ITS (Satellite Navigation, Apps etc), to help both cities and drivers with compliance rates.

Since 1.1.18 we are operating without EU funding, so we need to cover our costs, so:

CLARS Plus Membership provides (1,500€ per year) additional:
5) Ask questions on of the secretariat and other members.
6) A forum to ask questions, discuss issues, post information
