Calculate carbon emissions using the Kaya identity formula
How to calculate carbon emissions using the Kaya identity? The Kaya Identity Calculator does just that! Enter your data points into the calculator to find out your carbon emissions.
What is the Kaya Identity?
The Kaya Identity is a mathematical formula that breaks down the factors influencing carbon dioxide emissions. It looks at how many people there are, how busy things are, how much energy we use, and how dirty the energy is. The equation breaks down what makes carbon dioxide amounts go up or down.
How to Use the Calculator
Using the Kaya Identity Calculator is simple. Here’s how:
Input Fields
 Population (P): Enter the population size into the calculator to find its impact on emissions. For example,
7800000000
.  GDP per Capita (G/P): Enter the GDP per capita into the calculator to see how economic activity affects emissions. For example,
10000
.  Energy Intensity (E/G): Enter the energy intensity into the calculator to measure energy use per unit of GDP. For example,
0.5
.  Carbon Intensity (C/E): Enter the carbon intensity into the calculator to assess carbon emissions per unit of energy. For example,
0.3
.
Formula
The calculator uses the following formula to estimate carbon emissions:
Variables
Variable  Description 

Population (P)  Total number of people 
GDP per Capita (G/P)  Gross Domestic Product per person ($) 
Energy Intensity (E/G)  Energy use per unit of GDP (MJ/$) 
Carbon Intensity (C/E)  Carbon emissions per unit of energy (kg CO2/MJ) 
Calculation Examples
Example 1
 Population (P):
7800000000
 GDP per Capita (G/P):
10000
 Energy Intensity (E/G):
0.5
 Carbon Intensity (C/E):
0.3
Calculation Steps:
1. Population (P):

7800000000
2. GDP per Capita (G/P):

10000
3. Energy Intensity (E/G):

0.5
4. Carbon Intensity (C/E):

0.3
5. Calculate Carbon Emissions:
$$\text{CarbonEmissions}=7800000000\times 10000\times 0.5\times 0.3=11700000000000\text{kgCO2}$$
Example 2
 Population (P):
1000000000
 GDP per Capita (G/P):
15000
 Energy Intensity (E/G):
0.7
 Carbon Intensity (C/E):
0.25
Calculation Steps:
1. Population (P):

1000000000
2. GDP per Capita (G/P):

15000
3. Energy Intensity (E/G):

0.7
4. Carbon Intensity (C/E):

0.25
5. Calculate Carbon Emissions:
$$\text{CarbonEmissions}=1000000000\times 15000\times 0.7\times 0.25=2625000000000\text{kgCO2}$$
