Since January 2018, the Brussels environmental zone has been in place, covering all 19 municipalities of the Brussels Region. On an area of 161 km2 , the driving bans are permanently monitored with so-called ANPR cameras 365 days a year. As in the other environmental zones in Belgium (Antwerp and Ghent), registration is required to avoid the penalties. There is no sticker and nothing has to be stuck on the windscreen. The environmental zone is bordered to the west and north by the E19 and to the east and south by the E40. Both roads are exempt, as are several Park&Ride car parks at the border.

Antwerp has had a Low Emission Zone (LEZ) since 01.02.2017. The boundaries are the city centre of Antwerp and part of the Linkeroever district (between the E17, the Park & Ride Linkeroever and the Sint-Annabos). The environmental zone covers 20km² and affects approximately 200,000 inhabitants. As in the other environmental zones in Belgium (Brussels and Ghent), registration is required to escape the penalties. Driving bans are permanently monitored with so-called ANPR cameras 365 days a year.

Ghent was the third city in Belgium to introduce a Low Emission Zone (LEZ) on 01.01.2020, at the same time a speed limit of 30 km/h was set for the entire city area. The boundaries of the environmental zone are defined by the R40 ring road surrounding the city centre, with the exception of the N430, the B401 and N422. To avoid a fine of €150 - €350, registration is required, as in the other environmental zones in Belgium (Brussels and Antwerp). However, the registration for Antwerp also counts for the city of Ghent, as it is valid for the whole of Flanders.
