Annual carbon dioxide emissions in tonnes per person, from Our World in Data using the latest available country values in TerraBrawl.
Why This Ranking Matters
Examining CO2 Emissions per Person across all countries reveals patterns that might not be obvious at the national level. Regional clusters, outlier nations, and historical trajectories all become clearer when the full global picture is assembled in a single ranking.
Global Range
Values range from 0.05 t/person/yr (Congo, Democratic Republic) to 41.27 t/person/yr (Qatar) — a 764-fold difference across 213 countries.
Regional Patterns
Asian countries dominate this ranking, holding 10 of the top 20 positions. This strong regional concentration suggests shared economic, geographic, or policy factors that drive higher values across the continent.
Values are tightly clustered around the median of 3.20 t/person/yr, with most countries falling within a narrow range. A few outliers at the extremes account for most of the overall spread.
Notable Outliers
Qatar stands far above the rest, with a value 57% higher than second-place Kuwait. This extraordinary lead suggests unique national circumstances — geographic scale, resource endowment, or policy choices — that set it apart from even its closest competitors. The bottom five countries are all from Africa, pointing to regional challenges that affect co2 emissions per person across the continent.
