The Welsh Government has unveiled new guidance aimed at reducing nighttime lighting across the country, building on Wales’ existing reputation for dark sky areas like Eryri, which boost tourism. This initiative seeks to enhance life for both wildlife and residents while also cutting costs and carbon emissions, without compromising public safety. The guidance outlines principles for responsible lighting practices, emphasizing that illumination should only be used when necessary and at appropriate levels. It highlights the detrimental effects of light pollution on ecosystems and human health, advocating for energy-efficient lighting solutions that preserve the natural night sky. The aim is to balance the practical need for lighting with the preservation of dark skies, providing a framework for local planning and development efforts towards this goal.
