  France issued a decree to restrict and prohibit mainly outdoor lighting
effective from January 1st, 2019. Effectiveness of this legislation has been
evaluated in this study using GIS data which was first used in
\cite{2020MNRAS.493.1204A} (so called astroGIS database - \url{astrogis.org}).
A subset of Artificial Light layer of astroGIS database has been adapted for
years between January 2012 and December 2019. During 2019, radiance of $1.9
\times 10^{9}$ W cm$^{-2}$ sr$^{-1}$ has been released into space. Annual light
pollution in France decreased by 6\% after the enactment of artificial light
legislation. France continue to have potential Dark Sky Park locations for
example cities like Indre, Lot, Nievre and Creuse having the lowest light
pollution values. A strong correlation between population and light pollution
($R\simeq 0.83$) has been observed. A similar but a weak correlation can also
be observed for GDP ($R\simeq 0.28$). However, it is still too early to justify
whether the improvements observed in the dataset are due to the enactment of
the legislation or not.
