Environmental Impact Score vs Annual CO2 Emissions
公式
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:
Higher scores indicate lower environmental impact.
计算示例
A person with 12 tons CO2, 100 gal/day water, 25 lbs/week waste, 5,000 sq ft.
- 01Carbon: 100 - 12/16*50 = 62.5
- 02Water: 100 - 100/100*30 = 70
- 03Waste: 100 - 25/30*30 = 75
- 04Land: 100 - 5000/10000*20 = 90
- 05Overall: 62.5*0.4 + 70*0.2 + 75*0.2 + 90*0.2 = 72.0
常见问题
What does the environmental impact score mean?
The score rates your environmental impact on a 0-100 scale where higher is better. 80+ is excellent, 60-80 is good, 40-60 is average, and below 40 needs significant improvement.
Why is carbon weighted more heavily?
Climate change is the most urgent environmental challenge. Carbon emissions from energy and transport have the largest single impact on global environmental health.
How can I improve my score?
Focus on the lowest-scoring category first. Reducing carbon (renewable energy, less driving) typically has the biggest impact. Then address water conservation and waste reduction.
