CO2 Emissions per Capita: American Samoa

Analysis# American Samoa CO2 Emissions per Capita American Samoa's CO2 emissions per capita stand at 0.002 metric tons in 2024, representing one of the world's lowest levels. The territory peaked at 0.003 metric tons in 1981 before declining significantly. Since 1970, when emissions were recorded at zero, American Samoa has remained in the negligible range—far below global and regional averages. The consistent 0.002 metric ton reading from 2015 through 2024 demonstrates a plateau in recent years. This stability reflects American Samoa's small population, limited industrial activity, and reliance on imported goods rather than domestic manufacturing. The territory's minimal carbon footprint positions it among the least-polluting jurisdictions globally, though the data suggests no further substantial reductions are anticipated in the near term.
