CO₂ emissions per capita by country
Compare territorial fossil and industrial CO₂ emissions per person across countries.
Compare co₂ emissions per capita across countries on an interactive world map. Open any country for the latest value, the comparable-sample rank, the source, and the method.
What this measures
Higher territorial CO₂ emissions per person; lower territorial co₂ emissions per person.
Unit: tonnes per person. CO₂ emissions per person.
Methodology
Values are Our World in Data territorial CO₂ emissions per capita from the Global Carbon Budget 2025: fossil-fuel and industrial/cement CO₂ divided by OWID population. GCP country totals are national energy and cement statistics times emission factors, not satellite measurements; they are treated as observed, the same class as Ember generation terawatt-hours. Land-use change (LULUCF) and international aviation and shipping bunkers are excluded; bunkers appear only in the global total. Country rows are joined by ISO 3166-1 alpha-3; OWID aggregates and territories outside UN-193 are excluded. Map ranks are comparable-sample competition ranks among currently loaded countries (rank 1 is the highest emissions per person). Missing countries remain without a value.

Highest and lowest values
These lists use the same comparable-sample ranking as the map for 2024. They include only countries with a finite value among 191 available observations. Missing countries are unranked. This is not a complete world ranking.

How to read this layer
- Highest and lowest figures on this page are comparable-sample observations, not a complete world ranking. What does a rank mean?
- Grey countries on this layer are missing comparable values, not zeros. Why do some countries appear grey on the map?
Rankings, where shown, describe only countries with comparable values in the selected period.
