How this figure is calculated
Annual Net Emissions/Removals (Greenhouse gas, Total, Metric ton of CO₂) 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.
Annual Net Emissions/Removals (Greenhouse gas, Total, Metric ton of CO₂) ÷ Land area (sq. km)
Computed from
- Annual Net Emissions/Removals International Monetary Fund
- 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.
