温室ガス排出、最少に　２３年度、再エネ拡大で―環境省

　環境省は２５日、国内の２０２３年度の温室効果ガスの排出量は二酸化炭素（ＣＯ２）換算で前年度比４．０％減の１０億７１００万トンとなったと発表した。１３年度比では２３．３％の減少。電源構成に占める再生可能エネルギーと原子力を合わせた割合が３割を超えたことや、製造業の国内生産活動の減少により、過去最少を更新した。
　ＣＯ２排出量を部門別に見ると、全ての部門で減少。産業部門が前年度比４．０％減、家庭部門が６．８％減だった。運輸部門はバスやタクシーの利用が減り、０．７％減となった。（2025/04/25-08:40）

Japan's greenhouse gas emissions in fiscal 2023, which ended in March last year, declined 4.0 pct from the previous year to a record low of 1,071 million tons in carbon dioxide equivalent, the Environment Ministry said Friday.
   The figure was down 23.3 pct from fiscal 2013.
   The decrease came as the proportion of renewable and nuclear energy exceeded 30 pct of overall power sources and manufacturing activities slowed.
   Emissions from industry declined 4.0 pct from fiscal 2022 and those from households fell 6.8 pct. The transport sector posted a 0.7 pct drop as people used buses and taxis less frequently.
   The Japanese government has a goal of reducing emissions by 60 pct in fiscal 2035 from fiscal 2013 and by 73 pct in fiscal 2040 to achieve carbon neutrality by calendar 2050.
