Paris is constantly entering into its emergency measures as the city struggles with exceptionally high air pollution levels. Controls on vehicles, free public transport and advice to limit intense sports and avoid large traffic sites at time of high circulation are just some of the measures being taken by the French government to protect residents from the effect of the most prolonged air pollution in the last ten years.
Paris is not the only one; Athens, Madrid and Ljubljana are just some of the Europeans cities currently taking urgent steps to control growing air pollution; a problem which according to the Organisation for Economic Cooperation and Development (OECD) is set to cause as many as nine million premature deaths a year around the world in the next four decades. And the World Health Organisation (WHO) has described this problem as the “world’s largest single environmental health risk”.
Unfortunately, reducing the emission of new air pollutants does not remove those that are already in the air.
