Air quality
Air pollution peaks have an impact on health and environment. To avoid this impact, the Region has established different intervention levels of pollutants. Beyond a level, information is provided to the public. In some cases, measures are taken.
There are two types of air pollution:
- External site pollution peaks due to the concentration of fine particulate matter (PM10/PM2.5) and nitrogen dioxide (NO2) in the air (smog), also known as winter peaks
- External site ozone peaks, which mainly occur in summer
There are different levels of alert. The pollution peak (smog alert) is announced via:
- the electronic notice boards situated in and around the Brussels Region
- the website External site Qualité de l'air and its application Brussels Air
To minimize the fatal impact of a pollution peak on the environment and our health, it is advisable to take specific measures. These measures aim at decreasing the concentration of pollutants in the air and at reducing the scale of the peak. There are 4 levels according to the duration and the intensity of the winter pollution peak:
- External site Winter measures (smog) (in French)
Dispensations are no longer required. In case of a driving ban (level 2), the driver must provide proof to the police that he/she complies with the profile stated on the list of persons/vehicles that are still allowed to drive. More info:
