How this figure is calculated
Nitrous oxide (N2O) emissions (total) excluding LULUCF (Mt CO2e) divided by GDP (current US$), matched on country and year. Neither publisher issues this ratio as a series; it is computed here from both.
Nitrous oxide (N2O) emissions (total) excluding LULUCF (Mt CO2e) ÷ GDP (current US$)
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
- GDP Country official statistics, National Statistical Organizations and/or Central Banks
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.
