List of countries by carbon intensity of GDP

Carbon intensity or emission intensity of GDP is a measure that evaluates the amount of carbon dioxide (CO2) emissions produced per unit of GDP.

It provides an indication of how efficiently an economy uses carbon-based resources to generate economic output.

A lower carbon intensity indicates that less CO2 is emitted to produce a given level of economic output, indicating a more carbon-efficient economy.

Carbon intensity is measured by CO2 emissions in kilograms per International dollar (US dollar adjusted for purchasing power parity) of economic output.

Development of CO2 emissions in kilograms per international dollar of economic output in major countries over time.
