2. Differentiated traffic in Geneva

From 15 January 2020, whenever an increase in air pollution is observed or forecast in the short term, the circulation of vehicles with the highest pollutant emission levels will be restricted in the central Geneva urban area through a range of temporary and progressive measures (with the most polluting vehicles being targeted first).

This measure is based on the identification of the environmental performance of vehicles via a Stick'AIR sticker available in 6 different categories (from 0 to 5).

The Stick'Air

This differentiated traffic scheme offers the advantage of limiting pollutant emissions through restrictions that target vehicles with the most adverse impacts. The pollution produced by a vehicle can in fact vary considerably depending on its performance. For example, a passenger car with a diesel engine that meets the requirements of the Stick'AIR class 2 sticker emits 28 times less fine combustion particles than a diesel car too old to be eligible for a Stick'AIR sticker.

In practice, during a smog episode, only vehicles displaying the Stick'AIR sticker corresponding to the categories authorized will be permitted to travel in the predefined zone between 06:00 and 22:00.

Apart from certain listed exceptions, all motor vehicles are concerned, regardless of their place of registration.

What should I do during a pollution peak if my vehicle does not have an authorized Stick'AIR sticker ?

You will not be permitted to drive your vehicle in the differentiated traffic zone (centre of the canton) between 06:00 and 22:00. To travel within this zone, you could instead opt for soft mobility, car sharing (in a vehicle with an authorized Stick'AIR sticker) or public transport.

If air pollutant concentrations reach or exceed the warning level and so trigger the reinforced or expanded levels of differentiated traffic, you can take advantage of free public transport across the entire cantonal network (zone 10).


If my vehicle is not permitted to travel within the differentiated traffic zone, can I leave it parked there in the public space ?

Yes, but parking regulations will still apply. It’s therefore preferable to anticipate any possible parking restrictions before the differentiated traffic measure is activated.
