Crit'Air and low-emission zones: which used car to buy for city driving?
By Rédaction Quelle Occasion · updated on 19 October 2026
To drive without restriction in every low-emission zone (zone à faibles émissions, ZFE) currently in force, aim for a Crit'Air 1 or green car: an electric car, a plug-in hybrid, an LPG car, or a petrol car (hybrid or not) first registered from 2011. A diesel from 2011 or later is Crit'Air 2: today it can drive in the strictest ZFEs, those of Paris and Lyon, which target Crit'Air 3 and above. The rules do, however, depend on each urban area, and the debate on the future of ZFEs is not over.
Do ZFEs still exist in 2026?
Yes. Parliament voted to abolish them in the law on simplifying economic life (loi de simplification de la vie économique), but the Constitutional Council struck down that article on 21 May 2026 (decision no. 2026-903 DC). The censure was procedural: the measure had been added without any link to the original bill. The Council did not rule on the substance, which leaves the door open to a new text.
To date, Service-Public.fr counts 25 ZFEs in mainland France and 38 areas required to set one up (Service-Public.fr). For a car you will keep for several years, reason with the current rules, but leave yourself a margin.
What do ZFEs ban for private cars?
It depends on the urban area (Service-Public.fr):
- Paris and Lyon, under the reinforced regime, restrict Crit'Air 3 cars and above: diesels (and diesel non-plug-in hybrids) registered before 1 January 2011, and petrol cars (and petrol non-plug-in hybrids) registered before 1 January 2006. These restrictions do not apply to vehicles with more than 50 km of all-electric range in town.
- In the Greater Paris Metropolis, unclassified cars and Crit'Air 3, 4 and 5 cars may not be driven Monday to Friday from 8 am to 8 pm, except public holidays (Service-Public.fr).
- Elsewhere, the law requires at least a restriction on unclassified vehicles, and each local authority sets its own hours and timetable.
The level of restriction city by city is summarised in our diesel or petrol article. Always check the rules for your city on the official portal Mieux respirer en ville before buying.
Driving in a ZFE without a sticker or with a vehicle that is not allowed is punishable by a fine of up to €450, generally a fixed fine of €68 (Service-Public.fr).
Which Crit'Air sticker for each type of car?
The classification depends on the energy source and the date of first registration (Service-Public.fr):
| Energy | Sticker |
|---|---|
| Electric or hydrogen | Green, whatever the date |
| Plug-in hybrid | Crit'Air 1, whatever the date |
| Gas (LPG, CNG) | Crit'Air 1, whatever the date |
| Petrol from 2011 | Crit'Air 1 |
| Petrol from 2006 to 2010 | Crit'Air 2 |
| Diesel from 2011 | Crit'Air 2 |
| Diesel from 2006 to 2010 | Crit'Air 3 |
| Petrol from 1997 to 2005 | Crit'Air 3 |
Non-plug-in hybrids (Toyota, Renault E-Tech) are classified according to their fuel, like a petrol car. The sticker costs €3.85 and can only be ordered on the official website certificat-air.gouv.fr. Service-Public.fr presents it as the only official issuing site: avoid intermediaries.
Which used cars to choose for driving in a ZFE?
Electric (green sticker). The most future-proof solution against restrictions, if you can charge. Our guides record the Renault Zoe at €9,300 to €16,500, the Dacia Spring at €8,900 to €12,000, the Fiat 500e at €12,000 to €17,500 and the Peugeot e-208 at €13,000 to €20,000. Before buying, read our article on the battery of a used electric car and the ranking of the best electric city cars.
Hybrid (Crit'Air 1). No charging to plan, and lower consumption in town. The Toyota Yaris IV (€15,000 to €23,000) gets the "buy" rating in our guide; for the Toyota Auris II (€8,500 to €15,500 across all versions), our guide recommends favouring the 1.8 hybrid; the Renault Clio V is available as an E-Tech. See also the best hybrids. A plug-in hybrid, such as the Renault Captur II E-Tech Plug-in 160, is Crit'Air 1 whatever its date.
LPG (Crit'Air 1). An economical, often overlooked option. Several models in our guides have a factory LPG version: Dacia Sandero III ECO-G 100, Opel Adam 1.4 LPG, Opel Karl 1.0 LPG or Fiat Panda III 1.2 LPG. Have the switch from petrol to LPG and the servicing of the gas system checked.
Conventional petrol (Crit'Air 1 from 2011). The simplest choice on a small budget: a Toyota Aygo II or a Hyundai i10 II are Crit'Air 1 in all their versions. See also the best city cars and our selection at €5,000.
Diesel (Crit'Air 2 from 2011). Allowed today in every ZFE for a Euro 5 or 6 diesel, but it is the most exposed sticker if an urban area tightens its rules. Keep it for high mileage, especially on open roads.
How do you check a car's sticker before buying it?
- Look at the date of first registration and the energy source on the registration certificate, and compare with the table above.
- Ask the seller whether the sticker is on the windscreen. Only one is issued per vehicle, and it does not need renewing as long as it remains legible (Service-Public.fr).
- For a plug-in hybrid, check the electric range if you are targeting Paris or Lyon (50 km threshold in town).
- Check the local rules of every city you drive in, not just your own.

In practice
- City with a strict ZFE and charging available: electric.
- No charging: hybrid, LPG or petrol from 2011 onwards.
- Diesel: only recent (2011 onwards) and for lots of open-road driving.
- Always: check the rules of your urban area before signing.

Before you buy: check and equip
Check the history
Before paying, check the administrative status (lien, objection, declared claims) and the mileage recorded at the roadworthiness test.
Read fault codes
An OBD scanner plugged in under the steering wheel shows stored fault codes, even with warning lights off: useful during the test drive.
Parts and maintenance
Compare prices of car parts (timing, brakes, filters) to estimate the repairs to plan for.
Insure the car
Insurance prices vary widely from one model to another: get a quote before signing.
