CO2 Emissions per Capita: Hong Kong

Analysis# Hong Kong CO2 Emissions per Capita Hong Kong's per capita CO2 emissions reached 4.601 metric tons in 2024, representing a significant decline from its 1993 peak of 7.535 metric tons. Since 1970, the territory has reduced emissions by 91.2%, despite nearly doubling its population. Current levels remain nearly twice the 1973 low of 2.343 metric tons, reflecting Hong Kong's development as a global financial hub. A marked turning point emerged in 2020, when emissions dropped to 4.553 metric tons—the lowest level in decades. This decline coincided with pandemic-related economic disruptions and accelerated renewable energy adoption. Despite a modest rebound in 2021–2022, Hong Kong has stabilized emissions around 4.6 metric tons annually, suggesting a sustained shift toward cleaner energy infrastructure rather than temporary shock-driven reduction.
