hich zones require a Crit'Air sticker?
The Crit'Air certificate is only compulsory in certain zones. In Paris, the sticker is compulsory within the perimeter of the A86 motorway from Monday to Friday, from 8am to 8pm, except on public holidays.

Several large cities have also set up low emission mobility zones. The agglomerations concerned are: Lyon, Aix-Marseille, Toulouse, Nice, Montpellier, Strasbourg, Grenoble, Rouen, Reims and Saint-Étienne. From 2025, all cities and agglomerations with more than 150,000 inhabitants will be required to introduce a Low Emission Mobility Zone. In these towns, ‘non-classified’ vehicles (registered before 1997) will no longer be allowed on the roads, except by special dispensation.
