Le Havre's air quality faces significant challenges as France's largest container port, with shipping, petroleum refinery, and chemical industry emissions from the Grand Port Maritime de Normandie generating elevated SO₂, NOₓ, and industrial PM2.5 alongside heavy vehicle traffic on the A13 and surrounding road network. The English Channel generally provides strong maritime ventilation on westerly days, but Le Havre's industrial port intensity makes it one of northwestern France's more challenging urban industrial air quality environments throughout the year.
