How this figure is calculated
Cumulative CO₂ emissions by world region divided by Land area (sq. km), matched on country and year. Neither publisher issues this ratio as a series; it is computed here from both.
Cumulative CO₂ emissions by world region ÷ Land area (sq. km)
Computed from
- Cumulative CO₂ emissions by world region Global Carbon Budget (2025) – with major processing by Our World in Data
- Land area FAOSTAT, Food and Agriculture Organization of the United Nations (FAO)
Statizoid computes this series; the underlying measurements belong to the publishers named above. The arithmetic is applied to every country and year where both inputs report, and nothing is estimated unless the page says so.
