How this figure is calculated

Total greenhouse gas emissions excluding LULUCF (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.

Total greenhouse gas emissions excluding LULUCF (Mt CO2e) ÷ Land area (sq. km)

Computed from

Total greenhouse gas emissions excluding LULUCF 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.
