About the International Dark-sky Association, Colorado

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 more than a dozen 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.
