How this figure is calculated
Carbon dioxide emissions by income level 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.
Carbon dioxide emissions by income level ÷ Land area (sq. km)
Computed from
- Carbon dioxide emissions by income level 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.
