The 4 stages of LCA — RMUE:
"RMUE through the lifecycle"
- Raw material extraction — mining, drilling, harvesting
- Manufacturing — converting raw materials into the product
- Use phase — energy consumed during the product's life
- End of life — disposal, recycling, or incineration
Cradle to Grave visual memory: Picture a baby's cradle (birth = raw materials from the earth) and a gravestone (death = disposal back to the earth). Everything that happens in between is the LCA.
LCA limitations — DISC:
- Data quality issues — incomplete supply chain data
- Impact comparison difficulty — how to compare CO₂ vs habitat loss?
- Subjective boundaries — what counts as "inside" the assessment?
- Commercial bias — companies may cherry-pick favourable data
