Mission To preserve and protect the nighttime environment and our heritage of dark skies through environmentally responsible outdoor lighting.

Protecting the night sky from light pollution is a critical mission that supports quality of life, preserves wildlife habitat, and protects our access to the stars. The beauty of a starry sky has been central to inspiring human creativity, religion, philosophy, culture, and science through the ages. The International Dark-Sky Association leads the way globally in this mission to protect our natural nighttime environment.
