Life-cycle assessment looks at the environmental footprint of a product or process across its entire life, from raw material extraction to disposal or recycling. It collects data on inputs and outputs at each stage and translates them into impact categories like greenhouse gas emissions, energy use, and water depletion. The goal is to identify where the biggest environmental burdens occur, compare different options, and guide design and policy to reduce overall impacts. It’s not about health risks for workers, market analysis of product longevity, or auditing a company’s finances.
