Low Emission Zones

Low emission zones are zones where the most polluting vehicles are forbidden from driving. Zones are intended to improve air quality and so public health.

Criteria to enter in a zone are different according to the countries:

  • Some countries use an emission sticker. Only vehicles with an authorized emission sticker can enter the area.
  • Some countries use the emission standard. In this case, no emission sticker is required for the vehicle. The access criteria for driving in low emission zones depend on the category, fuel and euro norm of the vehicle.
  • Some countries combine the two different systems. In this case, some zones of the country use emission stickers while others are based on the emission standard criteria.
