Clearly, light pollution affects everyone. The twelve recommendations in the report are intended to reduce light pollution and its adverse effects. These recommendations will result in improved lighting conditions for safety and for reduced energy consumption, and will also serve as a means to help preserve the environment. Glare affects the ability of drivers to perceive objects or obstructions clearly. Particularly sensitive to this problem are elderly drivers.
Energy is wasted when excessive levels of illumination are used.
Inefficient luminaires can spill unwanted light well outside of the intended target area. Light trespass may be viewed as an invasion of privacy. Most obtrusive lighting conditions can be avoided. Inappropriate use of outdoor lighting can deteriorate the natural nighttime environment, particularly in areas preserved for wildlife. In addition, sky glow reduces the ability to observe the starry night sky.
