Can light pollution be subject to statutory enforcement?
28. We conclude that the problem of light pollution can be alleviated without the need for scientific measurement of sky glow. Sky glow is just one of three types of light pollution, the cause of which is well known, and is clearly visible – particles in the air and light shining above the horizontal. Light shining above the horizontal should be tackled directly by controls on the direction, position and type and duration of lighting, guidance on which should be included in the PPG on light pollution we have recommended. (Paragraph 145) 29. Light trespass and glare affects astronomers, but it can also affect us all. We are persuaded by the evidence that light trespass is measurable and controllable. We recommend that obtrusive light should be made a statutory nuisance.
