Kaya Identity Calculator

Decompose carbon emissions with the Kaya identity.

Ecology calculator: Enter four consistently scaled factors. The component SVG shows how each factor contributes multiplicatively.

Kaya factors

Population

GDP per capita

Energy per GDP unit

CO₂ per energy unit

CO₂ = population \cdot \frac{GDP}{population} \cdot \frac{energy}{GDP} \cdot \frac{CO₂}{energy}

How to use this calculator

CO₂ = population \cdot \frac{GDP}{population} \cdot \frac{energy}{GDP} \cdot \frac{CO₂}{energy}

Decompose carbon emissions with the Kaya identity.

The placeholders provide a reproducible example. Enter them to verify the result before using your own data.

Values must be finite and use compatible units. Displayed decimals are rounded, while calculations retain full precision.

What does this calculator do?

Decompose carbon emissions with the Kaya identity.

Why do fields appear or disappear?

Dependent fields follow the selected method, shape, ingredient, or unit mode.

Are all visible formulas semantic?

Yes. Formulas and structured results use native MathML, with text retained only for labels and copying.
