Eco Label Calculator — 公式
## 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

计算示例
Score a product: Materials 60, Energy 70, Packaging 50, Durability 75, Recyclability 65.
- Materials: 60 * 0.25 = 15.0
- Energy: 70 * 0.25 = 17.5
- Packaging: 50 * 0.15 = 7.5
- Durability: 75 * 0.20 = 15.0
- Recyclability: 65 * 0.15 = 9.75
- Total: 15.0 + 17.5 + 7.5 + 15.0 + 9.75 = 64.8
