Since January 1, 2025, the environmental vignette is mandatory in the Landel region. Without a sticker, motorists risk a fine. The vignette indicates how polluting a vehicle is and determines whether the certain zones can enter during periods of air pollution.
Those who travel to France can request the vignette via the official website certificat-air.gouv.fr. The application costs a few euros and must be done a few days in advance.
