Topic Summary: Life Cycle Assessment
Key Terms
- LCA: Systematic evaluation of total environmental impact across all stages of a product's life
- Cradle to grave: From raw material extraction (birth) to final disposal (end of life)
- Cradle to cradle: Circular version — end of life becomes raw material for a new product
- Carbon footprint: Total greenhouse gas emissions across the entire lifecycle
Must-Know Facts
- 4 stages: Raw materials → Manufacturing → Use → End of life
- Smartphone: 85% of environmental impact is in raw material extraction
- LCA limitations: data quality, commercial bias, subjective comparisons, boundary problems
- LCA considers: energy, carbon footprint, water use, toxicity, land use, waste
- Companies may manipulate LCA results — this is called greenwashing
- Used for product comparison, sustainable design, and policy development
