Reims (Grand Est):
The Low Emission Zone (ZFEm) in the Greater Reims area, in operation from 1 January 2022, aims to promote clean mobility. This measure will gradually restrict access to the centre of Reims and the Taittinger Lane (A344) for the most polluting vehicles. Currently, vehicles in the Crit'Air 5 and 4 categories are banned from January 2023. Air quality in Reims has fallen well below the legal limits. As a result, a 5-year moratorium has been introduced for CRIT'AIR 3 vehicles. This means that there will be no restrictions on CRIT'AIR 3 vehicles until January 2029.
