How this figure is calculated
Nitrous oxide (N2O) emissions (total) excluding LULUCF (Mt CO2e) divided by Population, total, matched on country and year. Neither publisher issues this ratio as a series; it is computed here from both.
Nitrous oxide (N2O) emissions (total) excluding LULUCF (Mt CO2e) ÷ Population, total
Computed from
- Nitrous oxide (N2O) emissions (total) excluding LULUCF EDGAR (Emissions Database for Global Atmospheric Research) Community GHG Database, Joint Research Centre (JRC) - European Commission
- Population, total World Population Prospects, United Nations (UN)
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.
