In order to make a significant contribution to the realization of a carbon-neutral society as the industry leader in low-carbon and decarbonization, the Kyuden Group
has clarified its goals for 2050, revised its management objectives (environmental objectives) for 2030 upward by backcasting, and formulated an Action Plan
containing specific strategies for achieving these targets.
○しろまる Reduction plan for emissions
・Amount of renewable energy developed: 5,000 MW (2030)
・Maximum use of nuclear power with safety as a top priority
・Lowering the carbon intensity of thermal power
・Conversion of all company cars to 100% EVs*1
(2030)
*1 Excl. special purpose vehicles
○しろまる Emissions reduction targets
2050 goals:
・We will reduce greenhouse gas (GHG) emissions across the entire supply chain to "virtually zero" during business activities.・We will contribute to the reduction of GHG emissions in society by promoting a shift to electricity-based energy consumption to the maximum extent possible,
providing a stable supply of environmentally-friendly energy, etc.
Through these efforts, the Kyuden Group will achieve "carbon negativity" as early as possible before 2050
2030 management (environmental) targets:
・We will reduce supply chain GHG emissions*2
by 60% (compared to FY2013 levels); and by 65% for our domestic business (compared to FY2013 levels)
*2 Total for Scopes 1, 2, and 3
・We will contribute to the electrification of Kyushu (Household: 70%; Commercial: 60%)
○しろまる Analysis of achievement level
Reduction of supply chain GHG emissions for FY2020 was 41.78 million tons, about a 32% reduction from FY2013 levels.
This result is due to our active development and introduction of renewable energy and stable nuclear power operations.

Discussion
and Analysis
̶ IF-EU-140a.3
The Kyuden Group manages the following risks regarding the use of water resources, which are essential for the power generation business.
In the hydroelectric power business, we use hydroelectric power station dams and diversion weirs, which discharge the water needed to maintain our rivers. We abide
by the set amounts of water that we have permission to take from rivers to produce electricity based on laws and regulations.
Where river levels are predicted to rise due to heavy rainfall, we implement water discharges or similar at our dams based on water governance agreements with the
national government or other authorities. In terms of preventing regional disasters, too, we do everything possible to cooperate to the best of our abilities.
Our thermal power generation business collects and reuses water for power generation to reduce the amount of water intake. Our thermal power generation business
and nuclear power generation business use seawater as indirect cooling water for power generation facilities. As such, we monitor the temperature difference
between water intake and discharge.
The results of verifying water stress in the current and future Kyuden Group facility locations using WRI Aqueduct 3.0 tools to identify water risks are as follows:
According to the Baseline Water Stress tool, maximum water stress is low-medium in the Kyushu region where the Kyuden Group has installed a power plant that uses
fresh water or seawater. Water-related risks such as droughts are assumed to occur less frequently there.

̶ IF-EU-240a.4
The Electricity Business Act in Japan stipulates that general transmission and distribution operators shall not refuse consignment supply in their supply areas without
justifiable grounds. When we accept an application to supply electricity in areas handled by Kyushu Transmission and Distribution, in principle, we supply to the
designated area. We believe that there is no difference in the opportunities for consumers to obtain low-cost energy. With that, we recognize that the factors affecting
electricity prices include the promotion of renewable energy generation based on the national system and fuel cost adjustments due to price fluctuations of thermal
fuel that affect electricity prices.

Kyushu Electric Power is working to maintain and improve the safety and reliability of nuclear power stations by accurately implementing safety activities based on
the quality management system for nuclear safety headed by the President and steadily making continuous improvements, including risk management to prevent
abnormalities.
In addition, we are continuously working to foster and maintain a corporate culture in which each employee can raise awareness of various risks of nuclear power, ask
what can be done to improve safety, and demonstrate leadership to improve performance.
We have also established the Nuclear Safety and Reliability Improvement Committee as a mechanism to receive opinions on the operation of nuclear power from a
third-party perspective as part of efforts to further improve the safety of nuclear power.
