Air: a vital element A man breath more than 15 000 air litres a day! air quality protection becomes an environmental, economic and health challenge Diapositive n 3

The French law : LAURE December 30 th, 1996 «implementing everybody s right to breath air that is not harmful to their health» Forecasting, monitoring, reducing and suppressing pollutions Protecting air quality Energy savings Substances released into the atmosphere are called pollution when : They can affect the health of plants, animals and people They can contribute to global warming They can affect monuments They produce odours Diapositive n 4

The French law : LAURE A large air quality monitoring network The definition of quality objectives, limit values, information and alert thresholds A better public information Transport and spatial planning Air pollution and energy are taken into account in urbanism and building policy Financial policy Diapositive n 5

Air monitoring in France There are 37 not-for-profit associations for air quality in France Diapositive n 6

What is COPARLY? r Who? An independent association What? To monitor air quality and to inform the population Where? In Lyon area when? Every hour, every day how? With measurements and modelling why? to study, to inform, to alert... And to improve air quality Diapositive n 7
