Gennevilliers' air quality reflects Greater Paris' most industrialised northern inner suburb on the Seine, with the A15 motorway and the Seine waterfront logistics and industrial complex — historically including major manufacturing and chemical operations — generating some of metropolitan Paris's highest sustained NOₓ and industrial PM2.5 readings. The Seine river provides limited ventilation, while the dense industrial port character keeps Gennevilliers consistently among the Île-de-France's most challenging urban industrial air quality environments throughout the year.
