Action required on light pollution

2010’s Grenelle II law set out measures against light pollution, but orders specifying their implementation have never been made public, which prompted environmental associations to refer the matter to the Conseil d’Etat.

“It is now urgent to move from intention to action so that these objectives are finally met,” said a spokesman.

Night light pollution, or photopollution, disrupts the biological clock, increasing the risk of cancer, diabetes and depression as well as disrupting ecosystems.
