Air quality

Air quality
According to every single indicator ambient air quality in Brussels has constantly improved over the past twenty years. There is still room for further gains, however. In the Plan Air Climat (FR/NL), the Brussels-Capital Region has undertaken to significantly reduce the emission of air pollutants.

Various surveys show that the inhabitants of Brussels are aware of what reducing air pollution entails in terms of mobility and consumption.

The concentration of pollutants in the ambient air in real time (FR/NL) can be checked on the Bruxelles Environnement Qualité de l'Air website. All data is provided by the Brussels-Capital Region’s telemetry network.

What to do during peak pollution

When the concentration of dangerous pollutants in the air reaches a certain value, emergency procedures must be launched by the Region’s authorities. The procedures during peak pollution (FR/NL) for private individuals, businesses, industry and transport companies are also published on the Qualité de l'Air website.

Carbon dioxide (CO2) is the main pollutant responsible for the greenhouse effect: over five million tonnes are emitted in Brussels every year. Its growing concentration in the ambient air is due to the steady rise in energy consumption related to heating, transport and industry.
