How this figure is calculated
The year-on-year percentage change in Sulphur dioxide and coal. Computed from consecutive annual observations; years either side of a gap are skipped rather than bridged.
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
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.
