Measures to reduce light pollution in the territory of national parks.

This law defines light pollution as visible radiation from artificial light sources, which can annoy people or animals and cause them harm or disrupt some of their activities. How light sources are located is crucial for the intensity of light pollution. The Act allows a municipality (Section 50 (3)(c)) to issue a generally binding decree adopting measures to reduce light pollution. These measures should be aimed at regulating the projection of neon signs and impacts on dark skies.
