History

International Dark-Sky Association (IDA) is a 501(c)(3) (tax ID #: 74-2493011) founded in 1988, and is dedicated to protecting the night skies for present and future generations.

Light pollution – the inappropriate use of artificial light at night – is an environmental pollutant that harms our planet and robs us of the opportunity to experience the wonder of a natural night sky.

Today, IDA is the recognized authority for night sky protection and has taken the lead in identifying and publicizing the negative impacts of artificial light at night on human health, wildlife and climate change.

We work with the public, city planners, legislators, lighting manufacturers, parks, and protected areas to provide and implement smart lighting choices.

Our public outreach efforts provide solutions, quality education, and programs that inform audiences across the United States and throughout the world. At the local level, our mission is furthered through the work of our U.S. and international chapters representing five continents.
