The following is a full list of nations or territories ranked by their fossil CO2 emissions per square mile in 2017 (in tonnes of CO2). For each nation, the estimates of fossil CO2 emissions per square kilometer (in tonnes of CO2), fossil CO2 emissions per capital (in tonnes of CO2), and total fossil CO2 emissions (in million tonnes of CO2) in 2017 are also presented. All figures were calculated using a public database released by Global Carbon Budget 2018.
