The Extrapolation Model
Global Temp = (User Tonnes / Global Average 4.8) × 1.5C
Understanding Your Results
| Metric | What It Means |
|---|---|
| Your Carbon Emissions | The estimated amount of CO2 (in tonnes) you emit per year based on diet, transport, and flights. |
| If Everyone Lived Like You | Global temperature rise projection using IPCC data assuming all 8 billion people copied your exact carbon lifestyle. A sobering way to view personal impact. |
