What is the primary purpose of a life cycle assessment (LCA)?

• A. Forecasts the financial profitability of a product.
• B. Evaluates environmental impacts across the product life cycle from cradle to grave.
• C. Measures only carbon emissions in manufacturing.
• D. Predicts consumer preferences for the product.

Answer: (B)

A life cycle assessment focuses on environmental impacts across the entire life of a product, from raw material extraction to disposal. This cradle-to-grave approach means every stage is considered—materials gathering, production, distribution, use, and end-of-life management like recycling or disposal—and across multiple impact areas such as greenhouse gas emissions, energy and water use, land use, and pollution. The aim is not to forecast profit, nor to measure only carbon emissions in one part of the process, nor to predict what consumers will prefer. Instead, LCA provides a holistic view that helps compare products and identify hotspots where redesign or changes can most effectively reduce overall environmental burden.
