The procedure at a glance
Where it is required
Low-emission zones exist or are being introduced in several big cities (Paris, Lyon, Grenoble, Strasbourg, Montpellier, Toulouse, Marseille…). Each authority sets restricted classes, hours and exemptions, and rules change: check the city's website and ecologie.gouv.fr. Other towns may impose restrictions during pollution peaks.
Advice from the association
Don't leave this procedure to the last minute — come and see us.
How the class is set
By fuel type and Euro standard (field V.9) or first registration date (field B). The oldest vehicles are unclassified. A petrol car generally has a better class than a diesel of the same year. Very old unclassified vehicles face the strongest restrictions.
Common mistake
Ordering from an unofficial site.
Ordering and price
Order only on certificat-air.gouv.fr: a few euros including postage, while copycat sites charge far more. The order confirmation can be shown until the sticker arrives. Prepare registration number, first-registration date and make. The sticker is posted to France or abroad.
Common mistake
Assuming foreign cars are exempt.
Foreign vehicles
Foreign cars also need the sticker in low-emission zones, ordered on the same site (foreign vehicles section) with the registration document. After registering in France, order a new one.
Common mistake
Keeping the old sticker after new plates.
