CO2 Emissions per Capita: Samoa

Analysis# Samoa CO2 Emissions per Capita Samoa's per capita CO2 emissions stood at 1.604 metric tons in 2024, reflecting a substantial increase from 0.462 metric tons in 1971—a 242% rise over five decades. The nation peaked at 1.78 metric tons in 2019 before declining slightly to current levels, remaining well above historical baselines despite recent moderation. The 2019 peak marked a turning point, followed by a sharp drop to 1.478 metric tons in 2020, likely reflecting pandemic-related economic contraction. Since then, emissions have stabilized in the 1.54–1.61 range through 2024, suggesting a plateau rather than sustained decline. Whether Samoa can reduce per capita emissions further depends on energy infrastructure investments and economic development patterns over the coming years.
