To convert these estimates to units of carbon dioxide (CO2), simply multiply these estimates by 3.667. Per capita emission estimates are expressed in metric tons of carbon. Population estimates were not available to permit calculations of national per capita estimates before 1950. Bunkers refers to fuels used for international trade and are not included in national totals.
