CieloBuio-coordinamento per la protezione del cielo notturno (Coordination for the protection of the night sky) is a non-profit organization that operates in Italy for the protection of the night sky by promoting a culture of eco-friendly lighting and raising public awareness about the phenomenon of light pollution.
In its fight against light pollution, CieloBuio has as a reference model to support and promote the law of the Lombardy region n. 17/2000, in all its forms and extensions.
This law is based on the criterion of zero pollution, according to which, with very few exceptions, no streetlamp can send light above the horizontal plane.
[2] CieloBuio works in collaboration with the Italian section of the International Dark-Sky Association and various scientific organizations to promote a national law protecting the night environment in the whole of Italy.
In 2004, CieloBuio was among the winners of the Innovazione Amica dell'Ambiente (Environmentally Friendly Innovation) Award, delivered by the Italian environmentalist organization Legambiente in recognition of the results obtained in terms of quality of light, energy saving and environmental protection through the application of the regional law n. 17/00 of Lombardy.
