Thursday, 12.07.2017, the French Conseil d’Etat promised developing measures fighting air pollution within the following nine months. Until now many European norms have not been fulfilled. This caused a lot of pressure from politic circles, civil society and organisations. As air pollution has measurable effects on the human body and health, it is a subject of interest touching most French. For this reason, a relatively short period of nine months has been given to the politicians who must act and present concrete actions.
