Life-cycle analyses assess environmental impacts across which stages of a product’s life?

• A. Packaging, marketing, and disposal
• B. Procurement, manufacture, use, and disposal
• C. Distribution, retail, and customer use
• D. End-of-life recycling only

Answer: (B)

Life-cycle analyses examine environmental impacts across the entire life of a product—from the initial procurement of raw materials, through manufacturing, use, and finally disposal. This cradle-to-grave perspective captures how choices at one stage affect outcomes at others, such as energy and emissions during production versus resource use during use and waste at end of life. The stage set that includes procurement, manufacture, use, and disposal covers all of these phases, so it best reflects the full environmental profile of a product. Options that focus only on packaging and disposal, or only on distribution and consumer use, or only on recycling at end of life, miss substantial parts of the life cycle and don’t provide the complete picture.
