Environmental Impact Calculator — सूत्र
## How to Calculate Environmental Impact Score
An environmental impact score combines multiple factors into a single metric.
### Formula
**Score = Carbon(40%) + Water(20%) + Waste(20%) + Land(20%)**
Each component is scored 0-100 based on comparison to benchmarks:
- Carbon: US average 16 tons/year
- Water: 100 gal/day average
- Waste: 30 lbs/week to landfill
- Land: normalized to 10,000 sq ft
Higher scores indicate lower environmental impact.

हल किया गया उदाहरण
A person with 12 tons CO2, 100 gal/day water, 25 lbs/week waste, 5,000 sq ft.
- Carbon: 100 - 12/16*50 = 62.5
- Water: 100 - 100/100*30 = 70
- Waste: 100 - 25/30*30 = 75
- Land: 100 - 5000/10000*20 = 90
- Overall: 62.5*0.4 + 70*0.2 + 75*0.2 + 90*0.2 = 72.0
