The zone à faibles émissions mobilité of the Métropole du Grand Paris was not created in 2025. It has applied since July 2019, with a first stage covering unclassified and Crit'Air 5 vehicles inside the perimeter of the A86 motorway, then a second stage on 1 June 2021 which extended the restriction to Crit'Air 4 vehicles. What has applied since 1 January 2025 is the following stage, the one covering vehicles classified Crit'Air 3.
The text governing this zone is arrêté n° AP/2024/415 of 20 December 2024 of the President of the Métropole (an arrêté is a French administrative order). Its article 1 creates the zone for a period of five years from the entry into force of the arrêté, and its article 13 fixes that entry into force on 1 January 2025: the term of this text is therefore 31 December 2029, and renewal is not a given. The perimeter covers the roads open to public traffic situated inside the zone delimited in the annexe. Excluded from the restrictions are, in particular, the A86 motorway, its slip roads, interchanges and direct connecting routes, the alternative routes in the event of closure of the A86, the routes of the Plan Neige et Verglas en Île-de-France and the roads listed in annexe 3 to the arrêté. The Métropole reports 77 communes concerned, including Paris.
Article 3 of the arrêté exhaustively lists the vehicles concerned, and cars, that is to say category M1 vehicles within the meaning of article R. 311-1 of the code de la route, are expressly among them. Article 5, I bans cars classified Crit'Air 3, 4, 5 and unclassified from driving Monday to Friday, from 8am to 8pm, public holidays excepted: a company car driven before 8am or after 8pm, at the weekend or on a public holiday is not covered. According to the Métropole and the Ville de Paris, the Crit'Air 3 stage thus covers diesel cars registered before 2011 and petrol cars registered before 2006. Save for an exception arising from its Euro standard, a diesel car registered since 2011, or a petrol car since 2006, is therefore not covered by the ban in force, and the arrêté contains no later stage covering the Crit'Air 2 class. The Métropole's 2026 leaflet displays a target of 100 per cent clean vehicles in 2030, which no restriction stage reflects to date.
Article 4 requires the Crit'Air certificate (the sticker) to be displayed on the vehicles covered by article 3, even where an exemption or a derogation applies, and the classification is that of the ministerial arrêté of 21 June 2016: it is that text, and not the metropolitan arrêté, which determines the class of a given car, according to its Euro standard where known and, failing that, its date of first registration. The legal basis is set out in VI, 3° of article L. 2213-4-1 of the code général des collectivités territoriales, which covers diesel and equivalent vehicles first registered before 31 December 2010 and petrol and equivalent vehicles before 31 December 2005; the correspondence between those dates and the Crit'Air 3 class is the Métropole's own reading, it is not a term of the statute. The Métropole states that the sticker is compulsory for driving, and even for parking during the restriction periods, and that its absence is liable to a penalty even during the educational period. We have found no public data on whether a missing sticker is actually being fined.
Penalties for the ban, for their part, have already been postponed by a year. The arrêté of 20 December 2024 provided, in its article 14, that the authorities responsible for enforcing it would organise penalties from 1 January 2026. By arrêté n° AP/2025/501 of 16 December 2025, published on the Métropole's website, its President replaced that date with 1 January 2027, without amending the other provisions. The recitals of that arrêté rely in particular on two grounds: the public procurement contract run by the State for the provision of automated enforcement equipment did not allow effective deployment in 2026, and the parliamentary procedure on the simplification law was then under way. The Métropole's press release of 22 December 2025 announces an educational period from 1 January to 31 December 2026 during which no penalty is applied, and the metropolitan page states that checks are occasional and for information purposes only.
A Crit'Air 3 car driving in the zone today during the restriction periods is therefore committing an offence without being fined. Under article 10 of the arrêté and article R. 411-19-1 of the code de la route, breach of these restrictions by a car is a third-class offence (contravention de troisième classe), for which the fixed fine is 68 euros under article R. 49 of the code de procédure pénale, the French code of criminal procedure, and the offence may lead to immobilisation of the vehicle. The arrêté of 16 December 2025 instructs the authorities to organise those penalties from 1 January 2027; it does not guarantee that they will be effective on that day, and the postponement that has already taken place shows that such a deadline can be moved by a mere arrêté.
Two forms of flexibility exist, and their practical reach needs to be measured before being turned into a travel plan. The Pass ZFE 24H opens a maximum of 24 full days per calendar year, but article 8 of the arrêté, whose article 9 sets out the procedure, requires the vehicle to be registered on the Métropole's platform at least 15 days before first use, then each date to be declared at least 24 hours before the period applied for. The Pass is requested only for days subject to restriction: for a car, Saturdays, Sundays and public holidays use up no days. Local derogations are also granted for a period not exceeding three years, renewable, on grounds and against supporting documents exhaustively specified in annexe 1 to the arrêté. Among the derogations open to businesses, two may concern an ordinary company car, with no specialised use and no special circumstances on the company's side: the one for auto-entrepreneurs (self-employed people under the French micro-enterprise scheme) and for companies with no more than 10 employees whose annual turnover is below 2 million euros and which undertake to renew or progressively upgrade their vehicles, granted for three years, or for one year renewable once for Crit'Air 5 and unclassified vehicles; and the one for business vehicles whose replacement by an authorised vehicle has been ordered, granted for one year renewable once.
