How to improve the air quality in Brussels?
Emergency measures are intended to deal with isolated events and are not designed to structurally improve air quality. The best way to combat smog is to modify our behaviour throughout the whole year.
A few recommendations
Choose an environmentally friendly method of transport: public transport, walk or cycle for short journeys, car-sharing (Cambio).
Save energy by insulating your home (energy saving grants are available) and by changing your habits: reduce the temperature by one or two degrees, wear a warm jumper, etc.
Change how you organise working schedules: travel planning and arrangements, tele-working, car-sharing, living near your place of work, and so on.
