In life cycle thinking, cradle-to-grave describes what scope?

• A. Resource extraction to end-of-life disposal
• B. Only operation
• C. Only manufacturing
• D. Only recycling

Answer: (A)

Cradle-to-grave is about the full life-cycle boundary of a product. It means the analysis starts with resource extraction (the cradle) and follows the product all the way to its end-of-life disposal (the grave). This includes raw material processing, manufacturing, distribution, use and maintenance, and finally disposal or recycling. By looking at all stages, you capture the total environmental impact of the product, not just a single phase. That’s why the best choice is the option describing resource extraction through end-of-life disposal. The other options focus on one phase only (operation, manufacturing, or recycling) and don’t represent the entire life cycle.
