CO2 Emissions per Capita: Macao

Analysis# Macao CO2 Emissions per Capita Macao's per capita CO2 emissions stood at 2.525 metric tons in 2024, representing a significant decline from its peak of 4.475 metric tons in 2004. Since 1970, when emissions were just 1.179 metric tons, the region has experienced a 114.2% increase overall. Despite this long-term growth, the most recent decade reveals a dramatic reversal in trajectory, with emissions falling by nearly 45% from their 2004 high. The sharp decline accelerated from 2021 onward, dropping from 3 metric tons to 2.525 metric tons by 2024. This sustained downward trend suggests structural economic shifts, possibly reflecting Macao's transition away from heavy industry and toward service-based sectors. Current emission levels now approach the low end of the historical range, indicating that recent policy and economic changes have effectively reversed decades of rising per capita emissions.
