IDA and IES Collaborate to Advance Quality Lighting to Reduce Light Pollution

LDS 13 CS IES Fundamentals 400

April 17, 2020

The International Dark-Sky Association (IDA) and the Illuminating Engineering Society (IES) announce a strategic collaboration to address the global issue of light pollution that negatively affects our environment and the human condition.

The Boards of Directors of IDA and IES have unanimously adopted Five Principles for Responsible Outdoor Lighting. By joining forces, IDA and IES seek to guide the outdoor lighting industry in the U.S. and beyond to be more socially and environmentally responsible.

“The Five Principles for Responsible Outdoor Lighting that unite our organizations are based on simple ideas; limit light at night to where and when it is needed, don’t overlight, and be sensitive to environmental concerns,” said Brian Liebel, Director of Standards and Research for the IES. “Following these Principles is not difficult and results in more effective and comfortable lighting installations.”

In recent years, light pollution has increased globally by two percent per year. The indiscriminate use of electric lighting at night leads to at least $3BN in wasted energy in the U.S. alone. This wasted light can harm wildlife, imperil important astronomical research, and can obscure our view of the star-filled sky.

“By following these simple principles, electric lighting at night can be beautiful, healthy, and functional. These principles work together to reduce light pollution, save energy and money, and minimize wildlife disruption,” said Ruskin Hartley, Executive Director of IDA.
