A comprehensive life cycle assessment (LCA) evaluates the environmental impact of products and systems throughout their entire existence—from raw material extraction, through manufacturing, transport, use, and final disposal. By considering the full journey of every material and product, interior designers can make informed choices that favor low-impact options. This approach enables the selection of materials and furnishings that have undergone environmentally conscious manufacturing and transport. By making LCA an integral part of the design process, responsible designers proactively reduce embodied energy and emissions, ensuring meaningful, long-term environmental benefits for both current users and future generations.
