LCA (Life Cycle Assessment) is a method used to evaluate the environmental impact of products or services throughout their entire life - from raw material extraction to disposal. Think of it as tracking a product's environmental "footprint" from cradle to grave. Companies use LCA to make their products more environmentally friendly, meet regulations, and show their commitment to sustainability. Similar terms you might see are "Life Cycle Analysis" or "Cradle-to-Grave Assessment." This is a key tool that helps businesses understand and improve their environmental performance.
