French environmental zones
In France you have a low emission zone (ZFE), permanent environmental zones (ZCR) and temporary environmental zones (ZPA). The latter are air pollution protection zones where access rules are temporarily imposed when there is a pollution peak. These zones can be active for a few days and are then only accessible with a valid environmental sticker, the 'Crit'Air'. For permanent zones, the access rules always apply.
Advice: purchase an environmental badge when travelling to France (more information under the heading: French environmental badges). Admission to an environmental zone depends on the colour and number of the environmental badge.

French environmental stickers
In France there are six different environmental stickers (called 'Crit'Air' there). Motorhomes built after 1997 qualify for a sticker. And your vehicle's emissions determine which sticker you get.
On this website you will find a simulator which shows you which Crit'Air Vignette you need to buy for your motorhome. You can order your French environment sticker here. Stick it on the bottom right (as seen from the inside) on the inside of the windscreen.
