Which statement best describes the purpose of a Life Cycle Assessment?

• A. To calculate the financial profitability of a product.
• B. To compare manufacturing costs for different materials.
• C. To evaluate environmental impacts across a product's life cycle, including goal and scope, inventory, impact assessment, and interpretation.
• D. To forecast future demand for a product.

Answer: (C)

A Life Cycle Assessment is a structured method to evaluate environmental impacts across a product's life cycle, from raw materials through production, use, and end-of-life. It follows four steps: defining the goal and scope (what will be studied, system boundaries, and the functional unit), compiling the life cycle inventory (all energy and material inputs and outputs), conducting the life cycle impact assessment (linking those flows to environmental impacts like greenhouse gases, resource use, and toxicity), and interpreting the results to draw conclusions and identify improvements. This holistic, process-oriented approach distinguishes LCA from analyses focused only on cost, profitability, or demand forecasting. Therefore, it best describes the purpose of a Life Cycle Assessment.
