How this figure is calculated
Nitrous oxide (N2O) emissions from Industrial Processes (Mt CO2e) 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.
Nitrous oxide (N2O) emissions from Industrial Processes (Mt CO2e) ÷ Land area (sq. km)
Computed from
- Nitrous oxide (N2O) emissions from Industrial Processes EDGAR (Emissions Database for Global Atmospheric Research) Community GHG Database, Joint Research Centre (JRC) - European Commission
- 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.
