Stick'AIR and the differentiated traffic scheme

2. Differentiated traffic in Geneva

From 15 January 2020*, the differentiated traffic measure can be triggered for this zone when an increase in air pollution (ozone, fine particles or nitrogen dioxide) is observed or forecast in the short term. In such an event, temporary traffic restrictions will be activated and only motorized vehicles displaying the Stick'AIR sticker corresponding to the authorized categories – in conformity with predefined thresholds and following a progressive approach – will be permitted to travel in this zone between 06:00 and 22:00.

In the absence of smog, no restrictions linked to the Stick'AIR sticker shall apply to this zone.

* A transitional period of two years has been accorded for goods transport vehicles.

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.
