The Illuminating Engineering Society (IES) and the International Dark-Sky Association (IDA) announced a strategic collaboration to address the global issue of light pollution that negatively affects our environment and the human condition.
The two parties adopted Five Principles for Responsible Outdoor Lighting and seek to guide the outdoor lighting industry in the U.S. and beyond to be more socially and environmentally responsible. The five principles addressed that light at night should be with clear purpose and used in necessary areas in low level and warmer color while under control.

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 US$3 billion 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.
Future avenues for engagement between the two organizations include convening experts to advance a new metric to characterize the color quality of outdoor electrical lighting, assessing and updating the Model Lighting Ordinance adopted by IDA and IES in 2011, and working to educate and inform municipalities and individuals about how these principles can be applied to save money and advance quality lighting that protects the night.
