How this figure is calculated

Methane (CH4) emissions from Transport (Energy) (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.

Methane (CH4) emissions from Transport (Energy) (Mt CO2e) ÷ Land area (sq. km)

Computed from

Methane (CH4) emissions from Transport (Energy) 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.
