The DLC compiled a list and interactive maps of locations with published outdoor lighting ordinances to mitigate light pollution. These maps show states, provinces, and cities/towns, throughout Canada and the U.S., with outdoor lighting ordinances. States and provinces shaded blue have a statewide/provincewide policy. The round markers indicate cities, towns, and counties with an ordinance. For further detail on individual policies, please inquire directly with the municipality.
