Kaya Identity Calculator

A mathematical identity used to estimate total CO2 emissions from human activity.

Live Calculation

Total Global CO2

24.00

Gt CO2

Live Step-by-Step Calculation

# Given Values:
Population: 8
GDP per Capita: 12000
Energy Intensity: 5
Carbon Intensity: 50
# Formula:
Total Global CO2 = (p * gdp * ei * ci) / 1e6
# Substitution:
Total Global CO2 = (8 * 12000 * 5 * 50) / 1e6
Final Answer: 24 Gt CO2

How it works

CO2=P×GP×EG×CECO_2 = P \times \frac{G}{P} \times \frac{E}{G} \times \frac{C}{E}

Biological Formula Standard

Developed by Yoichi Kaya, this identity decomposes emissions into population, wealth, energy efficiency, and fuel mix. It is used by the IPCC to create future climate scenarios.
