Types of environmental zones in France
France has a complex system of environmental zones which are linked to the Crit'Air stickers, which indicates the level of vehicle emissions.
Low Emission Zone (ZFE – Zone à Faibles Émissions)
This is the current standard type of environmental zone in large cities, always active, with clear signs and rules. It is the most common environmental zone in France. Only vehicles with a valid anti-pollution vehicle sticker (Crit'Air) are allowed to enter these zones, with the permitted categories depending on local regulations. Since 2025, ZFEs have been mandatory in all French cities with more than 150,000 inhabitants. The rules and exceptions may vary from city to city and are clearly indicated by road signs.
Permanent environmental zone (ZCR – Zone à Circulation Restreinte)
This was the original permanent environmental zone. It used to be widely used in Paris. Here, the Crit'Air vignette is always mandatory, usually all year round, but sometimes only at certain times (e.g. on weekdays from 8:00 a.m. to 8:00 p.m.). Many ZCRs have since been replaced by ZFEs, but the principle remains the same: permanent access requirements based on emission category.
Temporary environmental zone (ZPA – Zone de Protection de l'Air)
ZPA (and also ZCD) are temporary zones that only apply in the event of poor air quality. These zones are only activated in the event of severe or persistent air pollution. The size of the area is determined in advance, but the measures only apply during periods of poor air quality. Lane control lights and local websites indicate when a ZPA is active and which vehicles are not allowed to enter the zone.
Temporary Departmental Environmental Zone (ZPAD)
This is a variant of the ZPA, in which the size of the zone is not fixed, but depends on the current air quality in a department. Measures can be implemented immediately, such as setting an environmental zone or lowering the speed limit, depending on air pollution.
Zones de circulation différenciée (ZCD)
This type of zone is very similar to the ZPA, but is established by a city instead of a department. The rules are similar: temporary restrictions based on air pollution, where only vehicles with certain Crit'Air stickers are allowed to enter.
For all environmental zones, the local authority determines which vehicles are banned, based on the Crit'Air vignette. Always check the current situation and access rules in the French city or region you are travelling to before departing from your holiday home in France.
