An Assessment of Light Pollution Policy in Local Governments Across Australia: The Current Status and Implications

Light pollution entails unnecessary energy use, higher emissions and greater pressure on natural resources, as well as disrupting wildlife and human health. Specific policies and model ordinances are available for local governments to implement to address light pollution. This study analysed the light pollution policies of Australian local governments, in terms of specific details and whether the pattern of results reflects more of a polycentric or multi-level approach. Thirty local governments representing all of the urban areas in Australia with a population over 100,000 had their public lighting policy documents analysed. Very few local governments had taken steps toward addressing light pollution. The wide array of local governments did lead to some experimentation with light pollution policy, which provides test cases for others to consider. To obtain widespread coverage a multi-level approach may be needed, requiring higher levels of government to have light pollution policies in future. For now, very few local governments in Australia have any light pollution policies and of those, even fewer are comprehensive.
