How this figure is calculated
Sulphur dioxide and coal 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.
Sulphur dioxide and coal ÷ Land area (sq. km)
Computed from
- Coal consumption and sulphur dioxide emissions 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.
