CO₂ emissions per unit of GDP (production-based), 2022

This statistic measures how much carbon dioxide (CO₂) a country emits for each unit of economic output, using production-based emissions (emitted within the country’s territory) divided by GDP measured in purchasing power parity (PPP) international dollars. It’s a compact way to compare how carbon-intensive different economies are while partially accounting for differences in price levels and living costs.

Lower values generally indicate a less carbon-intensive economy—often due to cleaner electricity, more efficient industry, or a larger services sector—while higher values can reflect reliance on coal, energy-intensive heavy industry, flaring, or extraction-driven activity. Because it uses production-based emissions, it does not capture “imported” emissions embedded in traded goods, so consumption-based comparisons can differ for highly trade-exposed economies.
