Pittsburgh has a dark-sky ordinance since Sept 2021

September 2021, (our) beloved Pittsburgh became the first major city (in the US) to rethink how urban lighting will be conducted, passing a dark-sky ordinance not only for visibility of the night sky but also to use less energy, to help plants and animals by maintaining a crisper day-night cycle, to reduce glare for better night vision, and to benefit those in poorer neighborhoods who are disproportionately negatively affected by wasteful overlighting.
