Japan’s net greenhouse gas emissions fell by 1.9% in the fiscal year ending March 2025, dropping to a record low of 994 million tonnes, according to government data.
This marks the first time emissions have fallen below one billion tonnes since 2013, reflecting a steady long-term decline supported by greater use of renewable and nuclear energy and reduced industrial energy consumption.
In contrast, China—the world’s largest emitter—continues to see overall emissions growth, driven by coal-dependent industrial expansion, despite rapid renewable energy deployment.
Similarly, India’s emissions are rising steadily as energy demand grows to support economic development, with coal still dominating its power mix.
In Japan, fossil fuels still accounted for 67.5% of electricity generation, though this share has slightly declined. The country aims to reduce this to 30–40% over the next 15 years.
