Life Cycle Assessment Components
A Life Cycle Assessment (LCA) is a methodology for assessing the environmental impacts associated with all the stages of a product's life, from raw material extraction through materials processing, manufacture, distribution, use, repair and maintenance, and disposal or recycling.
Core LCA Stages
- Life Cycle Inventory (LCI): Compiles data on all inputs and outputs (energy, materials, emissions) for a product system.
- Life Cycle Impact Analysis (LCIA): Evaluates the potential environmental impacts associated with the LCI results.
- Life Cycle Interpretation: Identifies significant issues and presents results, considering data, assumptions, and limitations.
Excluded Element
An Emergency Preparedness Plan is related to operational safety and risk management within a facility or organization. It is not a component or stage of the Life Cycle Assessment methodology itself, which focuses on evaluating environmental burdens across a product's entire life cycle.
While LCA results might inform process improvements or risk assessments, the plan itself is separate from the LCA framework.
