The CLARS public website is the only single source of information on all urban access regulations in Europe. We give full, complete and reliable information on all low emission zones, urban road chargings and many other access regulation schemes. We provide you with the facts, without fuss and without trying to scare you about what is happening.

Do you want to have an overview of vehicular access regulations in Europe? The layout of our public website is aimed at vehicle operators looking at each city they wish to go to (see our How to use this site page). However, we have overview information on schemes, to help you get a Europe-wide picture. We have information on the increasing numbers of Zero Emission Zones, Low Emission Zones, traffic limited zones and many more. Ask us for more details.C

We are funded through Additional Services, Licence Fees and Sponsorship. We have a broad range of funders, and a key requirement is that no funders have influence on the content or editorial on the website. This remains neutral and factual, so that it can serve all users best.
