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.
Created in Lombardy in 1997 around a mailing-list of people interested in the topic of light pollution, CieloBuio now brings together professional and amateur astronomers, environmentalists, lighting engineers, and simply interested people throughout Italy. The current president is Dr. Fabio Falchi.
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.
CieloBuio in recent years has played a crucial role in the approval of other regional laws inspired by the Lombard model, among which we mention those in force in the regions of Emilia-Romagna (LR 19/03), Marche (LR 10/02), Abruzzo ( LR 12/05), Apulia (LR 15/05), Umbria (LR 20/05), Friuli-Venezia Giulia (LR 15/07) and Veneto (LR 17/09). In addition, the law passed in Lombardy has also inspired the drafting of laws in the Czech Republic (the first country in the world to enact legislation against light pollution, which applies throughout the country) and in Slovenia.
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.
