💡 Exam Tips for Life Cycle Assessment
🎯 Common Question Types:
- Define life cycle assessment (2 marks)
- Name/explain the four stages (4 marks)
- Evaluate the usefulness of an LCA (4-6 marks)
- Interpret an LCA data table and compare two products (3-4 marks)
📝 Key Command Words:
- Define: State what LCA means — cover all stages and mention environmental impact
- Explain: Describe what happens AND why it matters environmentally
- Evaluate: Give benefits AND limitations of LCA, then reach a balanced conclusion
- Compare: Use data from tables to make direct comparisons — always give specific numbers
⚠️ Common Mistakes to Avoid:
- Only mentioning manufacturing — LCA covers ALL four stages
- Assuming LCA results are always objective — they can be biased by commercial interests
- Confusing carbon footprint with full LCA — CO₂ is just one factor among many
- Forgetting to mention limitations in evaluate questions — examiners expect a balanced answer
