Life Cycle Assessment
Life Cycle Assessment (LCA) is a systematic process used to evaluate the environmental impacts associated with all stages of a product’s life, from raw material extraction through production, use, and disposal. By analyzing energy consumption, emissions, and resource use, LCA helps identify opportunities to improve sustainability and reduce negative environmental effects. It is widely used in product design, policy-making, and environmental management to guide decisions towards more eco-friendly solutions.

💡 Key Takeaways
- Understand the main life cycle stages considered in LCA (from raw materials to disposal).
- Identify environmental indicators evaluated in LCA (energy use, emissions, water use, resource depletion).
- Learn how to set a functional unit and system boundaries to compare products fairly.
- Discover how LCA results can point to improvement opportunities across design, production, and end-of-life.
- Recognize data requirements and limitations of LCA for informed decision-making.
❓ Frequently Asked Questions
What is Life Cycle Assessment (LCA)?
A systematic method to evaluate the environmental impacts of a product or service across its entire life cycle—from raw material extraction to disposal—using data on energy use, emissions, and resource consumption.
What stages are analyzed in a typical LCA?
Stages include raw material extraction, manufacturing, distribution, use, and end-of-life (disposal or recycling); the study is framed by its goal and scope.
What types of data are used in LCA?
Data on energy use, material and water resources, emissions to air, water, and soil, and other environmental exchanges across life-cycle stages.
How can LCA help improve a product's environmental performance?
By identifying hotspots with the largest impacts, enabling targeted design changes, material substitutions, or end-of-life improvements.
What are common limitations or challenges of LCA?
Data gaps and uncertainty, choice of boundaries and allocation methods, and results that depend on assumptions; LCAs may not capture social or economic factors.
