TC-SC-110a.2

Kioxia Metric/Qualitative Disclosure

In April 2023, Kioxia Group announced that by FY2050, the Group aims to achieve net-zero Scope1 greenhouse gas emissions (direct emissions from our business sites) and Scope2 emissions (indirect emissions from our use of purchased energy) across our global operations.

Regarding direct emissions from our manufacturing sites, since 2011 we have installed abatement equipment in 100% of our targeted facilities, aiming to eliminate during our manufacturing processes the emission of PFCs with high global warming potential. In addition, we are working with suppliers of abatement equipment to improve the performance of abatement equipment. The number of detoxification equipment installed from 2020 to 2023 will exceed 145 units per year on average, and the cumulative effect of detoxification since FY2017 will be 4.57 million t-CO2. Furthermore, we have improved the efficiency of operations through the introduction of online monitoring via the Internet of Things (IoT) and have started using carbon-neutral city gas.

We have additionally set a target of procuring 100% of our energy from renewable sources by FY2040. Since January 2023, we have installed three solar power generation systems at our Kitakami and Yokkaichi plants, the largest of their kind at any semiconductor plant in Japan (based on our own research, as of November 2023), and the third generation system commenced its operation in July 2024. While we continue to expand the use of these systems, we are also moving forward with the procurement of non-fossil certificates to boost our use of renewable energy.

Water Management

Accounting Metric

(1) Total water withdrawn, (2) total water consumed, percentage of each in regions with High or Extremely High Baseline Water Stress

Code

TC-SC-140a.1

Kioxia Metric/Qualitative Disclosure

(1) Total water withdrawn: 24,737 thousand ㎥
     (city water: 64 thousand ㎥ and industrial water: 24,673 thousand ㎥)
(2) Total water consumed: 6,356 thousand ㎥
      Percentage of each in regions with High or Extremely High Baseline Water Stress: 0%

Kioxia Group has commissioned external experts to evaluate water-related risks from the perspective of current and future water supply and demand risks; these are assessed using tools such as the World Resources Institute's WRI Aqueduct and the Water Risk Filter. We use these assessments to analyze risks such as water stress levels and seasonal variations in water supplies through the year 2040 in order to understand the potential impact on our business activities.

The outcome of the assessment of our Group’s manufacturing plants was confirmation that they are not exposed to any water risk likely to have practical financial or strategic impact prior to the year 2040. This assessment was based on investigations into such areas as water supply and demand risks (driven by seasonal changes, the frequency of droughts, water storage capacity and water source protection levels), the risk of water-related disasters such as flooding or landslides, and regional vulnerability to water pollution that might endanger public health or ecosystems.
