Prevention of light pollution

Decree published in the French “Journal Officiel” of 28 December 2018

The decree on the prevention, reduction and limitation of light pollution was published in the French “Journal Officiel” on 28 December 2018.

This French regulation is a result of the Grenelle 2 Act and defines the rules applicable to outdoor lighting installations. Its purpose is to prevent, limit and reduce light pollution causing excessive disturbance to people, fauna, flora or ecosystems, or preventing the observation of the night sky.

This decree, composed of eight articles, identifies several installation cases, then specifies the limits applicable to these different uses in each context.

Implementing legislation is being prepared to clarify certain provisions of this decree, but the general rules are not expected to change substantially.
