CO2 Emissions per Capita: Papua New Guinea

Analysis# Papua New Guinea CO2 Emissions per Capita Papua New Guinea's per capita CO2 emissions reached 0.517 metric tons in 2024, representing a significant decline from its peak of 0.8 metric tons in 2005. Since 1970, the country has increased overall emissions by 14.9%, though current levels remain well below the historical high. The nation's per capita footprint ranks among the lowest globally, reflecting its limited industrial development and smaller energy infrastructure compared to developed economies. A dramatic reversal occurred after 2016, when emissions peaked at 0.739 metric tons before declining sharply through 2018. Since that turning point, Papua New Guinea has maintained relatively stable emissions between 0.517 and 0.558 metric tons annually. The downward trajectory from 2018 onward suggests a sustained reduction in per capita carbon output, positioning the country favorably for continued low-emissions development as it expands its economy.
