Since 2017, Paris has been classified as a metropolitan Low Emission Zone (LEZ / ZFE-m). The Crit'Air sticker is mandatory for any vehicle driving in central Paris and the 76 Greater Paris Metropolis member towns. In 2026, constraints tighten: Crit'Air 4 and 5 fully banned, LAPI cameras deployed, fines up to €135. This guide recaps everything.
What is the Crit'Air sticker?
Created by the 21 June 2016 decree, the Crit'Air sticker classifies vehicles in 6 categories by pollution emissions: E (electric, 100% clean), 1, 2, 3, 4, 5 (cleanest to dirtiest). Class depends on engine type (petrol / diesel / hybrid) and first registration date. Sticker mandatory for any vehicle in a French LEZ.
Finding your Crit'Air class
Three methods. 1) Check your registration (carte grise), boxes P.3 and B. 2) Use the official simulator at certificat-air.gouv.fr. 3) Ask the garage at a technical inspection. For recent vehicles (post-2020), class 1 or 2 is standard. For used vehicles, class can be 3 to 5 - verify before buying if you live in a LEZ.
Where and how to order your sticker
Only one official channel: certificat-air.gouv.fr. Site run by the Ministry of Ecological Transition. 2026 rate: €3.77 (postage included). Delivery: 10-15 days. NEVER order on another site: scams charge up to €30 for the same sticker (a merchant was fined €5,000 in 2024 for misleading commercial practice).
Documents needed to order
Three items. 1) Vehicle registration (carte grise) - plate number and first-registration date. 2) Valid postal address for delivery. 3) Payment (bank card only). The ordered sticker is nominative and plate-linked - non-transferable between vehicles, non-resellable.
Current 2026 Paris restrictions
Since 1 January 2025, Greater Paris LEZ imposes: Crit'Air 5, 4 and unclassified banned 24/7 in central Paris and the 76 member towns. Crit'Air 3 banned weekdays only (8 am-8 pm). Crit'Air 1, 2 and E allowed. For 2028, proposed ban of Crit'Air 3 also 24/7 and Crit'Air 2 weekdays - pending political confirmation.
Professional exemptions
Several cases benefit from exemptions: emergency response, military or diplomatic vehicles, disabled-adapted vehicles, collector vehicles (30+ years with « collection » mention). For craftsmen and SMEs, a 24 annual-trip exemption on Crit'Air 3, 4 or 5 is available on application (Paris City Hall site, 5-day lead time).
2026 LAPI camera enforcement
Since July 2024, Paris has a network of 250 LAPI (Automatic Plate Reading) cameras on main axes. These cameras identify non-compliant vehicles in real time. Automatic fining is in pilot since June 2025: drivers receive an educational ticket (no fine) until June 2026. After that, effective fines of €68 (class 3) to €135 (class 4 or 5).
Physical checks
Alongside cameras, the National Police conducts physical checks on main axes (Haussmann, Voltaire, Sébastopol boulevards). These verify presence AND compliance of the sticker - a missing sticker is a €68 fine (Highway Code R411-19-1). A fake sticker: €135 and licence-suspension risk.
Buying second-hand: check the class
Before any second-hand purchase in Paris, check the Crit'Air class at certificat-air.gouv.fr with the plate. Crit'Air 3 limits you to evenings and weekends - awkward for daily use. Crit'Air 1 or 2 is ideal. Petrol cars pre-2006 or diesel pre-2011 are systematically Crit'Air 4 or 5: avoid for Paris.
Impact on vehicle value
Since LEZ introduction, Crit'Air 4 and 5 cars have lost 20-35% of value on the Paris market. Industry professionals advise Parisians in 2026 to favour used hybrids or electrics, which hold their value better and circulate without constraint.
Future Paris drivers: the right 2026 choice
If you are preparing your licence and planning a first Paris car, four reasonable options. 1) Used electric city car (Renault Zoé 2020+, Peugeot e-208: €10-14,000). 2) Plug-in hybrid city car (Toyota Yaris HSD, Honda Jazz Hybrid: €12-16,000). 3) Recent petrol Crit'Air 1 city car (< 5 years: €8-12,000). 4) Car-sharing (Getaround, Renault Mobilize): €5-8/h.
