CO2 Emissions per Capita: Japan

Analysis# Japan CO2 Emissions per Capita Japan's per capita CO2 emissions reached 7.842 metric tons in 2024, marking the lowest point in the 54-year data record. This represents a significant decline from the 2013 peak of 10.385 metric tons and reflects a broader downward trajectory since 1970, when emissions stood higher. Over the full period, per capita emissions have fallen 4.5%, demonstrating a sustained shift toward lower carbon intensity despite Japan's status as a developed industrial economy. The steepest emissions reductions occurred after 2013, with a consistent annual decline through 2024. Between 2015 and 2024 alone, per capita emissions dropped 19.1%—from 9.695 to 7.842 metric tons. This acceleration correlates with Japan's renewable energy expansion and energy efficiency improvements following the 2011 Fukushima nuclear disaster. The steady downward trend suggests Japan's decarbonization efforts continue gaining momentum.
