As other industries in Construction & Design lead the charge in developing sustainable materials and processes, the light¬ing industry still has work to do. At 25-80% more energy efficient than traditional lighting sources, LED lighting created a seismic shift in sustainable design. However, data on embodied energy, carbon impact, and waste stream is extremely limited. Life cycle data is not required to meet sustainability standards, code or policy. The embodied emissions of LED light fixtures can have a significant impact on the overall carbon emissions of a building. Many standard elements, from LED chips to typi¬cal heatsinks, are comprised of finite resources. Material extraction is extremely energy intensive and is damaging to local communities and ecosystems. Due to the unique nature of the materials, it can be challenging to recycle or re-use components, resulting in significant landfill waste.
