Mission Statement

The Colorado chapter of the International Dark-sky Association (IDA) works to protect the night skies for present and future generations. Key activities of the IDA include education about light pollution, recommendations for outdoor lighting, the IDA Fixture Seal of Approval, and the Dark Sky Places program. The IDA teaches about light pollution in 51 countries on six continents. The IDA's recommended best practices for outdoor lighting have become a standard worldwide. The IDA Fixture Seal of Approval has been awarded to over 1000 lighting fixtures. The IDA has officially recognized 14 Dark Sky Places in Colorado, ensuring ongoing conservation efforts in these special places. The Colorado chapter focuses on local efforts, including the conservation work of Colorado Dark Sky Places and supporting lighting ordinances in local governments throughout the state.

Organization History

The International Dark-sky Association was founded in 1988 to advocate for limiting light pollution. The IDA teaches about light pollution in 51 countries on six continents. The IDA's Dark Sky Places program recognizes night-sky conservation efforts throughout the world.


"Dark skies in the Rocky Mountains are a Colorado treasure and a key attraction for our tourism industry. I'm grateful to the International Dark-sky Association Colorado chapter for prioritizing this natural resource and reminding all of us to reduce light pollution for the public's health and well-being, as well as for our state's wildlife and natural environment," said Julie McCluskie, Colorado State Representative for House District 61.
