Light-Pollution Abatement

You can contact the LPA Committee Chair using our webform.


The goal of the RASC Light-Pollution Abatement (LPA) Program is to reduce the levels of light pollution in urban and rural areas by advising Federal, Provincial and Municipal governments and departments along with business and concerned citizens to take action to reduce unnecessary glare, uplight and light trespass.

White areas, are very heavily light polluted. Black = "dark sky" and White = "light polluted".

It is a constructive and advisory program that encourages meetings at the local level between concerned citizens and governments, business and the media to inform and advise these groups on the problems created by light pollution. We provide practical recommendations to reduce obtrusive lighting. The program is managed by the RASC LPA Committee consisting of volunteers from across Canada.

The RASC National LPA Committee supports local initiatives with the distribution of information and presentation materials. These are in the form of printed booklets, information sheets, and a slide set to complement a formal presentation on light-pollution abatement.

On the strategic national and regional level, the Committee recommends to Federal and Provincial governments the use of non-polluting exterior lighting designs and luminaires in projects under their jurisdiction. Further, the Committee advises governments as part of their infrastructure maintenance and renewal to replace older luminaires that produce glare and light trespass with luminaires with the full cut-off optics.

Mission Statement

In 1991, the Royal Astronomical Society of Canada established its Light-Pollution Abatement Committee to support measures to reduce Light Pollution.

Our mission is to work for social and legislative changes which will result in better, more responsible lighting practices in Canada, and the preservation of the nighttime environment for all to enjoy. This is accomplished by:

  • raising public and government awareness of the problem of light pollution,
  • forming or joining alliances with like-minded groups and organizations, and
  • making representations to governmental bodies.
