How this figure is calculated
emissions of air pollutants 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.
emissions of air pollutants ÷ Land area (sq. km)
Computed from
- emissions of air pollutants Hoesly et al. (2024) – Community Emissions Data System (CEDS) – 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.
