Life-Cycle Cost Analysis versus Life-Cycle Assessment: which is primarily an accounting tool for costs?

• A. Life-Cycle Cost Analysis (LCCA) evaluates total lifecycle costs, including installation, fuel, maintenance, salvage value, and inflation considerations.
• B. Life-Cycle Cost Analysis and Life-Cycle Assessment measure the same thing.
• C. Life-Cycle Cost Analysis focuses on environmental impacts across the lifecycle.
• D. Life-Cycle Cost Analysis is identical to a sustainability assessment.

Answer: (A)

The key idea is distinguishing a cost-focused financial evaluation from an environmental-impact assessment. Life-Cycle Cost Analysis is the tool that looks at all costs over the life of an asset or project as an accounting exercise. It adds up installation, fuel or energy costs, maintenance and repairs, replacements, operating expenses, salvage value, and inflation, often using discounting to compare present values over the chosen time horizon. This enables decision-makers to identify the option with the lowest overall economic burden or the best cost effectiveness across the entire lifecycle. Life-Cycle Assessment, by contrast, measures environmental impacts across the lifecycle, such as emissions, energy use, and resource depletion, rather than total monetary costs. Sustainability assessments broaden the scope further to include social and environmental dimensions in addition to economics. So the statement that best fits a primarily accounting tool for costs is Life-Cycle Cost Analysis, because it centers on quantifying and comparing all lifecycle costs rather than environmental impacts or broader sustainability dimensions.
