Japan has released its National GHG Emissions and Removals for 2024, announcing that the country’s GHG emissions reached 994 MtCO2 in 2024, representing a decrease of 1.9% (18.8 MtCO2) compared to 2023, and a 28.7% (399.5 MtCO2) decrease compared to 2013 (Japanese government press release, 14/04/2026).
According to the report, the recorded emissions have reached their lowest level since 2013, falling below the 1 Gt milestone for the first time. The main factors attributed for the decrease are determined as a reduction on energy consumption due to a lower production in the manufacturing industries and the increase of renewable and nuclear energy on the country’s power mix.
According to Enerdata’s Energy Report, Japan reached a 28.5% of renewables on its power mix in 2024. Including nuclear, carbon-free sources accounted for 36% on the same year.
