Life Cycle Assessment (LCA) is a systematic methodology used in product design to evaluate the environmental impacts of a product throughout its entire life cycle. It is also known as a “cradle to grave” approach because it studies impacts from raw material extraction, manufacturing, transportation, use, and final disposal or recycling. In Community Sciences and Community Development, LCA is important because it helps designers, industries, and communities create sustainable products that reduce pollution, conserve resources, and improve quality of life. The main purpose of LCA in product design is to identify environmental burdens at each stage of the product’s life and suggest better alternatives. It supports eco-friendly decision making, responsible consumption, and sustainable development. For example, while designing household products, clothing, packaging materials, furniture, or appliances, LCA can reveal which material or process causes greater harm to the environment.
