SASB INDEX
Relevant performance is organized in accordance with the Electric Utilities & Power Generators industry standards set by the US-based Sustainability Accounting Standards Board (SASB). SASB Standards were created primarily with companies and markets in North America in mind and incorporate some items that do not apply to our business. However, we have attempted to disclose as much information as possible.
Topic | Accounting Metric | Code | Result |
---|---|---|---|
Greenhouse Gas Emissions & Energy Resource Planning | (1)Gross global Scope 1 emissions |
IF-EU-110a.1 | 51,110,000t-CO2 |
(2)Percentage of Scope 1 emissions under emissions-limiting regulations | Not applicable | ||
(3)Percentage of Scope 1 under emissions-reporting regulations | 79% | ||
Greenhouse gas (GHG) emissions associated with power deliveries | IF-EU-110a.2 | 48,440,000t-CO2 | |
Discussion of long-term and short-term strategy or plan to manage Scope 1 emissions | IF-EU-110a.3 | Aim for net-zero emissions (carbon neutrality) by 2050. Concerning coal-fired power in Japan as we head toward 2030, we will phase out power plants that have become obsolete, starting with the oldest, and upcycle remaining power plants to highly efficient power systems that use hydrogen by adding gasification facilities, thereby reducing emissions. We will also introduce mixed combustion of biomass and ammonia, further reducing emissions. | |
Emissions reduction targets | 2050 Net-zero emissions 2030 Reduce CO2 emissions from the J-POWER Group’s domestic power generation business: 40%* (-1.9 million t)

Water Management | (1)Total water withdrawn | 59,268,000 thousand m3, 0% | |
(2) Total water consumed Percentage of each in regions with High or Extremely High Baseline Water Stress |
IF-EU-140a.1 | 6,800 thousand m3, 0%
|
|
Number of incidents of non-compliance associated with water water quantity and/or quality permits, standards, and regulations | IF-EU-140a.2 | 0 | |
Description of water management risks and discussion of strategies and practices to mitigate those risks | IF-EU-140a.3 | We manage the following risks involving the water resources that are indispensable for the power generation business.
In our hydroelectric power business, we comply with our legally permitted water withdrawal amounts. At hydroelectric power plants exceeding a certain scale,* we release water required to maintain river environments. We are working to reduce the amount of water we use in the thermal power business by capturing and reusing water. We also use seawater as indirect cooling water in power generation facilities, and monitor the temperature difference between withdrawal and discharge. Using WRI Aqueduct tools to analyze water stress in areas where our facilities are in Japan, we estimate the stress to be Medi- um-high at most, with low expected frequency of water-related risks such as drought.
