सारांश	Input-output life cycle assessment (IO-LCA) estimates the environmental burdens of a product or service over its life cycle by representing it as a unit of final demand within an environmentally extended input-output model. Rather than mapping individual processes, it leverages the Leontief inverse to capture the complete, economy-wide supply chain at once, eliminating the truncation that limits process-based LCA. Popularized by Hendrickson, Lave, and Matthews, IO-LCA and its hybrid extensions are distinct from process LCA in scope, data, and the way system boundaries are drawn.	Life Cycle Assessment is a systematic, ISO-standardized methodology for quantifying the environmental impacts of a product, process, or service across its entire life span — from raw material extraction through production, use, and end-of-life disposal. Codified in ISO 14040 and ISO 14044, and comprehensively reviewed by Finnveden et al. (2009), LCA enables decision-makers to compare alternatives, identify environmental hotspots, and support eco-design, with applications spanning products, buildings, energy systems, and public policy.
