Starlight Tourist Destinations

Starlight Destinations are visitable places characterised by excellent quality for the contemplation of starry skies and the practice of tourist activities based on this resource. The Starlight Tourism Certification System was created with the aim of encouraging, at world-wide level, the improvement of the quality of tourist experiences and the protection of the night skies in Starlight Destinations.The Starlight Certification seeks to guarantee the capacity to enjoy the view of the stars and...

Windows to the Universe

The scientific dimension of a starry night is an essential part of the legacy of the sky. The ability of the planet’s astronomical sites and observatories to detect and interpret data from outside the world we live in should be considered as a resource of extraordinary value for the progress of knowledge, as it has been throughout history. Dark skies are still the windows to our knowledge of the greater Universe. Unfortunately current areas devoted to astronomical observation do not enjoy ap...

Starlight Reserves

A Starlight Reserve is a site where a commitment to defend the night sky quality and the access to starlight has been established. Its main function will be to preserve the quality of the night sky and its associate values, whether they are cultural, scientific, astronomical, natural, or landscape-related. A Starlight Reserve will have a core or dark zone. This is an unpolluted area where natural night sky light conditions are kept intact. This core zone will be protected by a buffer or prote...

Star Parks - One Star at a Time Programme

A StarPark is a window to the firmament that each community voluntarily designates to enjoy the starry night sky. Its function is to claim and secure the right to starlight, especially for future generations.
Just as communities designate areas for recreation, sport, the enjoyment of nature or silence, these same sites and others can be places where the starry sky is enjoyed. A StarPark is an oasis that each community designates for stargazing/observing, a site where to learn under the st...

Summary of the suggestions to the Green Paper

  1. Consider that the first step toward efficiency is to limit the unnecessary light.
  2. Push for the adoption of standard rules that allow a substantial reduction of the levels currently used in outdoor lighting, guiding the market of SSL technologies.
  3. Carry out research work to see if and how light lowers crime and/or traffic accidents.
  4. Weight the benefits (eventually found in point c) against the benefits of different actions having the same cost (e.g.: more control by police).
  5. Consider the health problems of using light at night, especially with blue content and so limit the blue content of light used at night indoor and outdoor.
  6. Properly define the concept of eco-friendly technologies, which besides energy efficiency should take into account the control of light pollution by giving the following minimum prescriptions
  • do not allow luminaires to send any light directly at and above the horizontal;
  • do not waste downward light flux outside the area to be lit;
  • avoid over lighting;- shut off lights when the area is not in use;- aim for zero growth of the total installed flux, then a decrease (like it is happening to all other pollutants);
  • strongly limit the short wavelength ‘blue’ light.

7. Warn that specific light frequencies with a high blue component affect many wildlife species and alter ecosystem function in urban environments and beyond them.
