Which of the following is NOT a typical part of a Life Cycle Assessment?

• A. Evaluation of inputs and outputs across life cycle stages.
• B. End-of-life disposal assumptions.
• C. Only analyzing the production stage.
• D. Considering upstream energy use.

Answer: (C)

The main idea being tested is that a Life Cycle Assessment evaluates environmental aspects across the entire life of a product, not just a single stage. In a proper LCA, you look at inputs and outputs throughout all life-cycle stages, from raw materials and manufacturing to use and end-of-life disposal. You also consider energy used in the supply chain (upstream energy) and make assumptions about how the product is disposed or recycled at the end of its life. The statement about analyzing only the production stage contradicts this broader, system-wide approach, which is why it is not a typical part of an LCA. By focusing only on production, you’d miss significant impacts from materials extraction, transport, use, and disposal, which the LCA framework is designed to capture.
