Clichy's air quality reflects Greater Paris' northwestern inner suburb adjacent to the Levallois-Perret corporate corridor, with vehicle traffic on the A86 motorway and the Seine river industrial corridor generating elevated NOₓ alongside the dense urban residential and pharmaceutical manufacturing character. The Seine provides limited ventilation, while prevailing westerlies carry Atlantic air through the Paris basin and the industrial and corporate character maintains elevated readings throughout the year.
