International Dark-Sky Association (DarkSky)
DarkSky International restores the nighttime environment and protects communities from the harmful effects of light pollution through outreach, advocacy and conservation. Their International Dark Sky Places programme works with communities, parks, municipalities, and the public to certify and protect dark places for humans and wildlife alike. Their DarkSky Approved programme works with communities, manufacturers, retailers, designers, and others to evaluate and certify dark sky friendly outdoor lighting equipment, as well as dark sky friendly outdoor lighting projects. They raise awareness amongst the public about how excessive artificial light can harm humans, wildlife and our climate.
