Life Cycle Assessment (LCA) is a systematic tool used to evaluate the environmental impacts associated with a product, process, or service throughout its entire life cycle — from raw material extraction, through production and use, to final disposal or recycling.
Also known as a “Cradle to Grave” approach, LCA is one of the most important scientific tools for assessing environmental sustainability.
- Why is LCA an Essential Sustainability Tool?
- Identifying Critical Impact Points
• LCA helps detect the most environmentally harmful stages in a product’s life cycle, enabling effective improvement decisions.
- Guiding Sustainable Design
• Provides scientific data to support the development of more efficient products with lower environmental impact.
- Supporting Green Marketing and Environmental Certifications
• Helps products obtain sustainability labels such as EPD and boosts consumer confidence.
- Ensuring Regulatory Compliance
• Assists companies in meeting local and international environmental regulations.
- Enabling Informed Decision-Making
• A powerful tool for manufacturers, governments, and consumers to make environmentally conscious decisions.
- Main Stages of a Product’s Life Cycle
- Raw Material Extraction (Cradle)
Involves activities used to obtain natural resources such as mining, logging, agriculture, and other raw material extraction processes.
- Manufacturing and Production
Covers the processing of raw materials, energy consumption, emissions, and waste generated during production.
- Transportation and Use
Involves the environmental impacts of packaging, distribution, and actual use of the product by the consumer.
- End-of-Life (Grave)
Addresses how the product is handled after use — whether through landfilling, incineration, or recycling — and calculates the environmental impact of each option.
- LCA Implementation Phases
- Goal and Scope Definition
• Purpose of the study.
• Analysis boundaries (Cradle-to-Gate or Cradle-to-Grave).
• Functional unit used for comparison.
- Life Cycle Inventory (LCI)
• Collect quantitative data on all inputs (e.g., materials and energy) and outputs (e.g., emissions and waste).
- Life Cycle Impact Assessment (LCIA)
• Climate change
• Resource depletion
• Water and air pollution
• Human and ecosystem toxicity
- Interpretation
• Analyze results to draw clear conclusions and provide recommendations for reducing environmental impact and improving sustainable performance.
