How to Calculate an Eco Label Score

An eco label score helps consumers compare the environmental friendliness of products.

Formula

Score = Materials(25%) + Energy(25%) + Packaging(15%) + Durability(20%) + Recyclability(15%)

Scoring Criteria

  • Materials: Recycled content, sustainably sourced, non-toxic
  • Energy: Manufacturing energy, use-phase energy
  • Packaging: Minimal, recyclable, no single-use plastic
  • Durability: Long lifespan, repairable, warranty
  • Recyclability: End-of-life recycling potential

    • Exemple Résolu

    Score a product: Materials 60, Energy 70, Packaging 50, Durability 75, Recyclability 65.

    1. Materials: 60 * 0.25 = 15.0
    2. Energy: 70 * 0.25 = 17.5
    3. Packaging: 50 * 0.15 = 7.5
    4. Durability: 75 * 0.20 = 15.0
    5. Recyclability: 65 * 0.15 = 9.75
    6. Total: 15.0 + 17.5 + 7.5 + 15.0 + 9.75 = 64.8
