How this figure is calculated

The year-on-year percentage change in Nitrous oxide (N2O) emissions from Industrial Combustion (Energy) (Mt CO2e). Computed from consecutive annual observations; years either side of a gap are skipped rather than bridged.

Computed from

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.
