Sustainability Score Calculator — Formula
## How to Calculate Your Sustainability Score
A sustainability score rates your lifestyle across five key impact areas.
### Formula
**Score = Energy(25%) + Transport(25%) + Food(20%) + Waste(15%) + Consumption(15%)**
### Rating Each Area (0-100)
- **Energy**: Renewable energy use, efficiency upgrades, smart thermostats
- **Transport**: EV/hybrid, public transit, biking, less flying
- **Food**: Plant-based, local, minimal waste
- **Waste**: Recycling, composting, zero-waste practices
- **Consumption**: Buy less, buy used, repair, quality over quantity

Rate yourself: Energy 50, Transport 40, Food 55, Waste 60, Consumption 45.
- Energy: 50 * 0.25 = 12.5
- Transport: 40 * 0.25 = 10.0
- Food: 55 * 0.20 = 11.0
- Waste: 60 * 0.15 = 9.0
- Consumption: 45 * 0.15 = 6.75
- Total: 12.5 + 10.0 + 11.0 + 9.0 + 6.75 = 49.3
