There are many organisations with initiatives related to dark skies:
The International Dark-Sky Association (IDA) is the world authority on light pollution and is the leading organization combating light pollution to protect the night skies for present and future generations.
The International Dark Sky Places (IDSP) Program was founded in 2001 to encourage communities, parks and protected areas around the world to preserve and protect dark sites through responsible lighting polices and public education. A number of UK National Parks have been awarded International Dark Sky Park and Reserve Status, areas designated by the IDA for the quality of their night skies.
Dark Sky Discovery Sites is a nationwide network of places that provide great views of the night sky and which are accessible to everyone. In order to qualify for Dark Sky Discovery Site status, the locations need to meet a number of criteria that make them safe and accessible as well as having suitably dark skies.
