Impact of the LEZ

How will the LEZ influence air quality?

By introducing the LEZ in Brussels, emissions of the pollutants which are most harmful to health, namely nitrogen oxides, fine particles and especially black carbon (BC), can be reduced. 

Better air quality will be beneficial for all, and will especially help to improve the health of Brussels inhabitants.

Why are the restrictions for diesel vehicles more stringent than for petrol vehicles?

In terms of emissions of pollutants, specifically nitrogen oxides and fine particles, diesel vehicles have a greater impact on our air quality than petrol vehicles. Consequently, it was decided to establish stricter access criteria for diesel vehicles.

Which other measures does the Region take to improve the air quality?

The Brussels Government targets all activity sectors which emit pollutants into the atmosphere. That is why the Air, Climate and Energy Plan was approved on June 2nd 2016.

In addition to the LEZ, this plan anticipates measures with regard to the energy efficiency of buildings, better monitoring of air quality, energy production from renewable energy sources, and measures in the economic sectors, consumption patterns and product use. More info here.

An additional LEZ?

Will other cities in Belgium also introduce a LEZ?

Yes: there is a low emission zone in the city of Antwerp since 1/02/2017. Mechelen and Ghent will also introduce a LEZ from 2020.

Note: The access criteria of the LEZ in Flanders are not exactly  the same as the LEZ in Brussels. Relevant information about the LEZ in Flanders can be found here.

Are there LEZs in other countries?

Yes: many European countries have introduced a LEZ in their major cities. Most major German cities have one.  They also exist in the Netherlands and Italy. London has a LEZ and Paris has recently established a sticker system.

All information regarding LEZs in Europe can be found here.


In order to have access to the legal base of the implementation of the low emission zone in the Brussels-Capital Region, you will find below :

  • The ordinance dated December 7th, 2017 which modifies the ordinance dated May 2nd, 2013 on the Code bruxellois de l’Air, du Climat et le la Maîtrise de l’Energie (a.k.a « CoBRACE) enabling the effective implementation of one or several low emission zone on the Brussels Region territory (published in the Moniteur belge on December 14th, 2017)
  • The order dated januari 25, 2018, of the Government of the Brussels-Capital Region regarding the establishment of a low emission zone (published in the Moniteur belge on December Februari 2nd, 2018).

The introduction of the LEZ is a project which requires the cooperation of various government departments and actors, specifically: Brussels Environment, Brussels Mobility, Brussels Regional Informatics Centre (BRIC), Brussels Prevention and Security and Fiscality Brussels.
