Driving in Geneva

Switzerland: 1 scheme to know about before you drive in.

The short answer for Geneva

Geneva has one driving restriction on our books: the Circulation différenciée (low emission zone). What is a low emission zone?

What it means for your car

Petrol or LPG. At the strictest alert level a petrol car must be Euro 4 or newer; at the mildest it must be Euro 2 or newer. The chain from the vehicle to that answer runs through the macaron, because the regulation never names a Euro standard in its articles — it names a sticker number, and the annexe turns the sticker number into a Euro standard. For a passenger car running on petrol the annexe reads: Euro 5 and 6 are macaron 1, Euro 4 is macaron 2, Euro 2 and 3 are macaron 3, and Euro 1 and anything older is hors catégorie, entitled to no macaron at all. Light commercial vehicles are classed on the same petrol scale; heavy goods vehicles, buses and coaches use the heavy standards, with Euro VI at macaron 1, Euro V at 2, Euro III and IV at 3 and Euro II and older hors catégorie; two-, three- and four-wheelers are classed Euro 4 at macaron 1, Euro 3 at 2, Euro 2 at 3, first registered between 1 June 2000 and 30 June 2004 at macaron 4, and before 31 May 2000 hors catégorie. The bans then arrive one class at a time. Article 8 makes alert level 1 bar macaron 5 and every vehicle with no macaron; article 9 adds macaron 4 at level 2; article 10 adds macaron 3 at level 3. So a petrol car is only ever caught by the last of those, because no petrol car is classed 4 or 5: Euro 2 and 3 petrol cars are macaron 3 and are stopped at level 3 alone, and a petrol car older than Euro 2 has no macaron and is stopped from level 1. Euro 4 petrol and newer is never restricted at any level. Gas and plug-in hybrid vehicles take macaron 1 whatever their Euro class, electric and hydrogen vehicles take macaron 0, and both are therefore clear at every level. The French Crit'Air sticker is recognised here under article 5(7) and the canton states the two systems use identical performance requirements and identical numbering, so a Crit'Air 2 petrol car may be read straight across.
Diesel. At the strictest alert level a diesel car must be Euro 5 or newer; at the mildest it must be Euro 3 or newer. Diesel is classed one macaron worse than petrol at every rung of the annexe, which is why a diesel driver meets this scheme far sooner than a petrol one. For a passenger car running on diesel the annexe reads: Euro 5 and 6 are macaron 2, Euro 4 is macaron 3, Euro 3 is macaron 4, Euro 2 is macaron 5, and Euro 1 and older is hors catégorie. Light commercial vehicles use the same diesel scale; heavy goods vehicles, buses and coaches run Euro VI at macaron 2, Euro V at 3, Euro IV at 4, Euro III at 5 and Euro II and older hors catégorie. Reading that against the three levels: a Euro 2 diesel car is macaron 5 and is stopped as soon as the scheme is switched on at all, together with everything older that carries no macaron; a Euro 3 diesel is macaron 4 and is stopped from level 2; a Euro 4 diesel is macaron 3 and is stopped at level 3; a Euro 5 or Euro 6 diesel is macaron 2 and is never restricted. So the answer to 'may I drive in' depends on which level is running, and the honest general rule for a diesel car is that Euro 5 is the standard that is safe at every level. The canton's illustration of why the scale is drawn this way is its own: it states that a diesel passenger car meeting the macaron 2 requirements emits 28 times less combustion particulate matter than a diesel too old to qualify for any macaron at all. Determining the class is the holder's own responsibility, from the vehicle's fuel and its 'Code émissions' in box 72 of the Swiss registration document, or for an EU vehicle from the vehicle type, the fuel type and the Euro standard on the registration certificate; the canton publishes the conversion table for each case and will correct a misclassified import through the office cantonal des véhicules.

The schemes, one by one

• Circulation différenciée Low emission zone

  Geneva's low emission zone is the only one in the corpus that is switched on rather than left on.

  Most days of the year there is no restriction at all inside the perimeter; when the canton measures or forecasts a pollution peak, the department responsible for transport orders the circulation différenciée by immediately enforceable departmental decree, and from that moment the dirtiest vehicles may not drive in the centre of the canton between 06:00 and 22:00.

  The instrument is the Règlement régissant le dispositif d'urgence en cas de pics de pollution atmosphérique, rsGE K 1 70.09, made by the Conseil d'État on 6 November 2019 and in force since 15 January 2020, under articles 13A(4) and 15D to 15J of the cantonal act applying the federal environment law. What decides a driver's case is a sticker.

  Every motor vehicle is classed 0 to 5 by fuel and Euro standard on the regulation's own annexe, and the class is shown by a Stick'AIR macaron glued inside the windscreen; a vehicle too old for any class is hors catégorie and carries none. The restriction then arrives in three steps, and each step bans one more class. Alert level 1 bars macaron 5 and every vehicle without a macaron.

  Level 2 adds macaron 4 and makes all Unireso public transport free from the following day. Level 3 adds macaron 3 and bans open fires. For an ordinary car that resolves to two numbers: at the worst level a petrol car needs to be Euro 4 or newer and a diesel Euro 5 or newer, and at the mildest level a petrol car needs Euro 2 and a diesel Euro 3.

  Where you are registered makes no difference — article 15E(3) says so expressly, and it catches foreign plates as squarely as Genevan ones — and the French Crit'Air sticker is accepted in place of the Swiss one, with identical numbering. Two things make this scheme easy to misread.

  It is not a charge: the macaron costs 5 francs once, which the regulation states is its production and distribution cost, and it lasts the life of the vehicle. And it is not permanent: the same perimeter carries no restriction at all in the absence of smog, so a record that simply said 'Geneva has a low emission zone' would warn a driver every day of the year about a rule that ran twice between 2020 and August 2025.

  The canton announces an activation the day before by e-mail alert, by app and on variable signs at the edge of the perimeter, and the scheme has been through the courts: the Chambre constitutionnelle of the Cour de justice upheld the canton's power to create environmental zones on 27 August 2020 while quashing three provisions, and the Conseil d'État re-enacted the two threshold articles on 11 November 2020.
