Our mission
DarkSky International restores the nighttime environment and protects communities from the harmful effects of light pollution through outreach, advocacy, and education.
From bold conservation initiatives to responsible outdoor lighting programs, DarkSky supports a growing global community enacting meaningful change worldwide.
Restoring balance
Light pollution affects more than our view of the stars, it disrupts wildlife, harms human well-being, wastes money and energy, and contributes to climate change.
Through quality lighting choices guided by the Five Principles for Responsible Outdoor Lighting, we can reduce light pollution and protect the night.
