The Commonwealth of Independent States (CIS) had the highest carbon dioxide intensity worldwide in 2023, at 0.46 kilograms of CO₂ per U.S. dollar (kCO₂/$15p). The Middle East followed, with an emission intensity of 0.46 kCO₂/$15p. In 2023, the Middle East and Africa were the only regions to have a higher carbon intensity when compared to 2000 levels.

Carbon dioxide emission intensity worldwide in 2000 and 2023, by region
(in kilograms per U.S. dollar)
*CO₂ intensity is the ratio of CO₂ emissions from fuel combustion over Gross Domestic Product (GDP), and measures the CO₂ emitted to generate one unit of GDP. GDP is expressed at constant exchange rate (2015 U.S. dollar, using purchasing power parities). This removes the impact of inflation. CO₂ emissions cover only the emissions for fossil fuels combustion.
