Founded in 1988, the International Dark-Sky Association (IDA) is dedicated to protecting the nighttime environment and our heritage of dark skies through quality outdoor lighting. Light pollution is an environmental threat that harms our planet and robs us of the opportunity to experience the wonder of a natural night sky. Since its founding, IDA has taken the lead in identifying and publicizing the adverse impacts of artificial lighting on wildlife, the climate and health.

Outdoor lighting in the U.S. alone uses some 120 terawatt hours of energy per year. IDA estimates that at least 30 percent of light generated is wasted due to poor design, releasing 21 million tons of CO2 into the air every year.
IDA advances light pollution abatement by working with manufacturers, planners, legislators and citizens to provide and implement lighting that is energy efficient, cost effective and dark-sky friendly.

IDA’s conservation program, International Dark Sky Places, was created in 2001 to recognize excellent stewardship of the night sky. Designations are based on implementation of stringent lighting management plans, outreach programs to educate the public about night sky protection, and provide access to the night environment provided through stargazing parties and events. Since 2001, IDA has certified more than 70 such places in 15 countries across six continents.

The good news is that light pollution, unlike many other forms of pollution, is reversible and each one of us can make a significant difference! However, being aware that light pollution is a problem is not enough; spe-cific actions can be taken to limit incorrect, excessive, or unnecessary use of light. You can start by minimiz-ing the light emitted into the night sky from your own home and community by following a few simple steps: 

  • Use fully shielded, dark-sky-friendly fixtures. That means lights that shine down, not up into the sky.

  • Install timers, motion sensors and dimmer switch-es, and turn off lights when not in use.

  • Use long-wavelength lights with a red or yellow tint to minimize negative health effects and reduce impact on the night sky.

  • Keep your blinds closed.

  • Use right amount of light

Educate your family and friends on matters related to light pollution. Many people are unaware about the negative impacts of artificial light at night to human health, wildlife and the environment. By being an ambassador and explaining the issues to others you will help bring awareness to this growing problem and inspire more people to take the necessary steps to protect our natural night sky.  For more information, please visit: www.darksky.org
