It is also Japan’s largest operator of coal-fired power plants. J-POWER is a joint venture partner in the Clermont, Narrabri and Maules Creek coal mines in Australia.

In 2022, ACCR and a US$3 trillion investor group, including Man Group, HSBC Asset Management and Amundi, began engaging with J-POWER on its decarbonisation commitments and strategy. In 2022 and 2024 ACCR co-filed resolutions calling for the company to take more ambitious climate action. In 2024, J-POWER announced it would close five coal power generation units by FY2030.
