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.

    Ejemplo Resuelto

    A person with 12 tons CO2, 100 gal/day water, 25 lbs/week waste, 5,000 sq ft.

    1. Carbon: 100 - 12/16*50 = 62.5
    2. Water: 100 - 100/100*30 = 70
    3. Waste: 100 - 25/30*30 = 75
    4. Land: 100 - 5000/10000*20 = 90
    5. Overall: 62.5*0.4 + 70*0.2 + 75*0.2 + 90*0.2 = 72.0
