CO2 Emissions per Capita: Guam

Analysis# Guam CO2 Emissions per Capita Guam's per capita CO2 emissions stood at 0.002 metric tons in 2024, matching the all-time peak recorded in 1971. Since 1970, when emissions bottomed at 0.001 metric tons, the territory has experienced a 100% increase. This doubling reflects Guam's growing economy and energy consumption over five decades, despite the territory's small population and geographic isolation. From 2015 onward, Guam's emissions have stabilized at 0.002 metric tons annually, suggesting a plateau rather than continued growth. This plateau period spanning nearly a decade indicates that energy use and carbon output have reached an equilibrium relative to economic activity. Without significant policy shifts toward renewable energy or efficiency improvements, emissions appear positioned to remain at current levels in the near term.
