Namur's air quality reflects the Meuse-Sambre confluence in the Walloon industrial valley, with vehicle traffic on the E411 and E42 motorways and surrounding chemical and manufacturing industry contributing elevated NOₓ. The Ardennes plateau to the south provides cleaner air on southerly wind days, while cross-border industrial pollution from the Charleroi corridor elevates the regional background throughout the year.
