Life-cycle analysis serves primarily to evaluate:

• A. The environmental impacts of a product across its life cycle
• B. The financial profitability of a product
• C. The marketing strategy for a product
• D. The energy efficiency of a factory

Answer: (A)

Life-cycle analysis looks at every stage of a product’s existence to understand its environmental burden. It tracks inputs and outputs from raw material extraction through manufacturing, transportation, use, and end-of-life disposal or recycling, and it assesses impacts like greenhouse gas emissions, energy use, water use, waste, and ecosystem effects. The goal is to see where the most significant environmental impacts arise and to compare options to reduce the overall footprint. This is why it’s about the environmental performance of a product across its life cycle, not about profitability, marketing, or the energy efficiency of a single factory. For example, a packaging choice might look worse in terms of waste at the end of life even if manufacturing uses less energy, and LCA helps reveal that trade-off to guide better decisions.
