 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.
