(1) Gross global Scope1 emissions and (2) amount of total emissions from perfluorinated compounds

TC-SC-110a.1

(1) Scope 1 (Direct emissions): 410,400t-CO₂
(2) 320,600t-CO₂

Discussion of long-term and short-term strategy or plan to manage Scope1 emissions, emissions reduction targets, and an analysis of performance against those targets

TC-SC-110a.2

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.

(1) Total energy consumed, (2) percentage grid electricity, (3) percentage renewable

TC-SC-130a.1

(1) 4,676,500МWh (2) 96.5% (3) 0.3%

(1) Total water withdrawn, (2) total water consumed, percentage of each in regions with High or Extremely High Baseline Water Stress

TC-SC-140a.1

(1) Total water withdrawn: 24,737 thousand ㎥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.

Amount of hazardous waste from manufacturing, percentage recycled

TC-SC-150a.1

(1) Wastes generated amount: 9,849t
(2) Recycled rate: 89%

The above hazardous wastes are aggregated as “specially-controlled industrial wastes” under the Waste Management and Public Cleansing Act in Japan.

Description of efforts to assess, monitor, and reduce exposure of employees to human health hazards

TC-SC-320a.1

Since January 2021, Kioxia Group has been pursuing the acquisition of occupational health and safety management systems certification (ISO 45001:2018) for its manufacturing and R&D sites. As it moves to comply with the requirements for this certification, Kioxia Group is making efforts to continuously reduce health and safety risks through risk assessment and compliance with relevant laws and regulations, and is making its health and safety management measures more visible.

TC-SC-330a.1

The Kioxia Group operates globally and employs people of many different nationalities.

With offices in 10 countries and regions, the Kioxia Group has 1,776 employees working at our overseas locations (excluding those temporarily dispatched from Kioxia Group in Japan). Kioxia Group in Japan employs 155 non-Japanese people from 15 countries and regions (As of March 31, 2024).

Percentage of employee engagement

TC-SI-330a.2

Kioxia Group regularly conducts employee engagement surveys as a starting point from which to enhance employee engagement and revitalize the organization. The survey results are used in conjunction with opinions voiced separately by employees to identify any problem areas, and formulate and implement measures to resolve these. In FY2022, we conducted an anonymous worldwide survey targeting about 14,000 employees and received responses from 89% of them.

The results of these surveys are shared with the President & CEO, Executive Officers and department heads and are utilized to help improve employee engagement. In FY2023, we provided feedback to employees on the results of the previous survey and implemented measures to address issues identified in the survey.

Description of the management of risks associated with the use of critical materials

TC-SC-440a.1

Kioxia Group has been promoting the responsible minerals sourcing based on the Kioxia Group Responsible Minerals Procurement Policy.

Our policy stipulates that Kioxia Group will prohibit use as raw materials of tin, tantalum, tungsten, gold and cobalt obtained from the Democratic Republic of the Congo or neighboring countries and other conflict-afflicted and high-risk areas (commonly known as CAHRAs) where inhumane acts such as human trafficking, slavery, forced labor, child labor, abuse, or war crimes are suspected.
