What description best matches cradle-to-grave in life cycle thinking?

• A. From emission to end-of-life.
• B. Waste generation is the main focus.
• C. Tracks resources from extraction to disposal.
• D. Emphasizes endless reuse cycles.

Answer: (C)

Cradle-to-grave describes tracking resources from extraction to disposal. It uses lifecycle thinking to evaluate environmental impacts across the full range of a product’s existence—from where materials come from, through manufacturing and use, to the end-of-life stage and final disposal or recovery. This boundary captures the complete material flow, not just waste generation or emissions. By contrast, cradle-to-cradle emphasizes endless reuse cycles, and cradle-to-gate only covers up to the factory gate. So the best description is tracking resources from extraction to disposal.
