What does LEZ mean?

LEZ stands for "Low Emission Zone". The term is used to designate where polluting vehicles are not allowed to drive in a given city, or areas of that city. It is one of the measures taken in numerous European cities to improve air quality and consequently public health.

Several studies by the World Health Organisation, as well as various actions of the European Commission, have highlighted the poor air quality in Brussels and its subsequent impact on public health. Moreover, air pollution increases the risk of strokes, heart disease, lung cancer and acute respiratory disorders, in particular asthma. In Belgium, 12,000 premature deaths have already been attributed to poor air quality. By prohibiting the most polluting vehicles from the Brussels Capital Region, the quality of the air can be improved for everyone. For Brussels inhabitants, visitors and commuters.
