The charts below detail the resource consumption and environmental load of the fiscal 2020 J-POWER Group operations within Japan.

The * marks denote data that are the subject of third-party assurance.(Please refer to section 9-2「Third-Party Assurance Regarding Environment-Related Information」)

  1. Note:The scope of applicability includes J-POWER and its 26 consolidated domestic subsidiaries, which are engaged in the electric power business, electric power related business, andother business.The amounts attributed to consolidated subsidiaries are based on percentages corresponding to J-POWER’s equity share. Note that equity method affiliate s (one company in Japan) are included in the calculation of CO2 emissions from thermal power stations.

Notes:

  1. 1.Other than that discharged as wastewater, almost all industrial-use water used in thermal power stations is released into the atmosphere as steam.
  2. 2.River water used in hydroelectric power stations is not included in the input figures, as all such water is returned to the river after power generation.
