Neuilly-sur-Seine's air quality reflects Greater Paris' most affluent inner western suburb adjacent to the Bois de Boulogne, with vehicle traffic on the A86 and Boulevard du Général de Gaulle generating sustained NO₂ alongside the dense residential and financial character of one of France's wealthiest communities. The Bois de Boulogne's substantial woodland to the east provides a meaningful local clean-air buffer, while prevailing westerlies carry Atlantic air through the Paris basin and the park proximity provides relatively better conditions than many inner Paris districts.
