Exclusion

Please explain

Our non-manufacturing facilities such as headquarters and sales offices as well as some of ourassembly/processing plants, which require a very small amount of water for production, are excluded.

These non-manufacturing facilities are excluded because their water withdrawals and wastewater
discharges are considerably small, and hence their water risks are negligible.

Important

The availability of sufficient amounts of good quality freshwater is vital for the Asahi Kasei Group, since many of our plants use a significant amount of good quality
freshwater for cooling, steam production, and washing. Good quality freshwater is essential for most of our raw materials suppliers as cooling water and boiler feed water,in particular. We believe the availability of sufficient amounts of good quality freshwater will continue to be vital for our direct operations in future, although ourdependency on freshwater might slightly diminish as we go through a structural change away from water-hungry petrochemical products production towards high valueadded chemical products production. The availability of good quality freshwater will continue to be important for our suppliers in future as well, since boiler feedwater has
to be good quality freshwater and certain cooling processes will continue to require freshwater.

Not very
importantNot very
important

Although we rely to some extent on recycled water, we do not use any brackish or produced water, since our plants are located where freshwater resources are abundant.
We understand that our raw materials suppliers rarely use recycled, brackish or produced water. The availability of sufficient amounts of recycled, brackish or produced
water is therefore not very important for the Asahi Kasei Group and our raw materials suppliers alike. We do not anticipate that we will use brackish water if we consider
where we operate, and the possibility of us using any produced water in the future is even much lower because we are not involved in the mining of gas, oil or metals.
However, there is a possibility that we and our suppliers will use more recycled water in the future especially in operations where freshwater resources are expected to be
more scarcer.

Two plants are in China, one is in South Korea, Thailand, and the U.S.A respectively.
The volume of water withdrawn at these plants represents only a tiny fraction of the
Asahi Kasei Group's total water withdrawals, but the plants have been striving to
reduce their water use. This has contributed to the year-on-year decrease in thevolume of water withdrawn at these plants.

Water from third party sources is relevant because we use it where drinkable quality water is required. The volume ofwater from third party sources, mainly municipal water, we withdrew in FY2022 decreased significantly from theprevious year.
We assume that the main reason for this substantial drop in the volumes of drinking water withdrawal was the rapid
rise in telecommuting due to the COVID-19 pandemic.

We understand that, the higher the share of our procurement spend, the higher the risk of our operations being affected by a water-related adverse event at a supplier, andthat it is very effective and efficient to work together with our supply chain members in order to solve global water issues. That is why we send out a CSR questionnaire to
our major suppliers from which we procure a significant amount of products. Specifically, in FY2022, we sent out a CSR questionnaire to those suppliers covering 71% interms of the number of suppliers and 82% in terms of procurement spend. Information obtained from suppliers is used not only to assess water risks in our supply chain, butalso to encourage suppliers to make improvements by providing them with feedback. We believe that this functions as an incentive for our suppliers to respond to aquestionnaire.

Rationale for your engagement
The Asahi Kasei Group has set “coexistence with the environment” as a group vision, and positions the challenge of global environmental measures as the most important
issue. In particular, the Asahi Kasei Group’s policy on global environmental measures stipulates “conservation of water resources” and pledges to contribute to theconservation of water resources worldwide through our business and products. In relation to the business of recycled cellulosic fiber (trade name “BEMBERG”), Asahi Kasei
Corporation has been implementing initiatives such as technical and educational support and community development (including purification projects for contaminatedrivers) for stakeholders involved in the final product from the procurement of raw materials (cotton linters) in India. This business model also includes improvement ofwastewater purification system for industrial use, which is indispensable for the sustainable development of textile industry considering the global environment. Specifically,
the company is implementing initiatives with dyeing manufacturers and other stakeholders aimed at achieving zero wastewater at dyeing plants using the hollow fiber
membrane “Microza” developed by the company for wastewater treatment generated during fabric dyeing.
Impact of the engagement and measures of success
Asahi Kasei Corp. has been exporting recycled cellulose (cupro textile, trade name BEMBERG), which is used as a raw material for sari, traditional female clothing in India,
since 1976.
As of 2021, Asahi Kasei had contracts with about 10 dyeing plants and about 60 garment factories, and the volume of cupro textile handled was about 6,000 tons. Asahi
Kasei Corp. started the challenge of the construction of the wastewater purification system for the industry considering the global environment, which is indispensable for thesustainable development of the textile industry, while aiming at the business expansion of BEMBERG and hollow fiber membrane Microza in India. Specifically, it aims toachieve zero wastewater in dyeing plants using Microza for wastewater treatment generated during dough dyeing. This will enable us to conserve valuable natural water
resources through environmental conservation and water reuse around our plants and to contribute to the expansion of our business. By 2023 cumulative amount of 40,000
m3/day textile dyeing effluent will be treated and recycled back to the respective textile dyeing process, which is equivalent to saving daily water access to natural water
resources for approx. 25,000 households.

Asahi Kasei Group classifies chemicals, based on the type and scope of hazards, according to international standards, such as REACH and GHS. Regarding hazardous substances <Not
in water systems, in Japan, 28 substances with high toxicity to living organisms and the environment are regulated as hazardous substances in accordance with the Water Pollution
ApplicaPrevention Act. We recognize that the substances regulated by the Water Pollution Prevention Act need to be managed and reduced as the top priority substances for water pollution ble>prevention worldwide. The Asahi Kasei Group takes great care in handling the chemical substances used in product manufacturing. In addition, since we have taken thoroughmeasures to completely prevent the outflow of chemical substances even in the event of an unexpected accident, no violations of laws and regulations have occurred for years.

W3.1a(W3.1a) Describe how your organization minimizes the adverse impacts of potential water pollutants on water ecosystems or human health associated with youractivities.
Water pollutant category
Other synthetic organic compounds
Description of water pollutant and potential impacts
Our plants release potentially hazardous chemicals into the public water bodies, some of which are suspected to be carcinogenic and/or teratogenic. For example, if theNobeoka plant accidentally released N,N-dimethylacetamide (DMAc)—suspected to be carcinogenic and teratogenic—into the sea, DMAc could cause cancer anddeformities when humans are directly exposed to the chemical, which we assume to be rare. Although there are no effluent quality standards for DMAc, we have been
trying to minimize the release of DMAc into the environment.
Value chain stage
Direct operations
Actions and procedures to minimize adverse impacts
Assessment of critical infrastructure and storage condition (leakages, spillages, pipe erosion etc.) and their resilience
Please explain
The Nobeoka plant collects the wastewater containing DMAc and separates DMAc from the water using three distillation towers; the water is then recovered and reused.
The recovery rate is nearly 100% but some of the reflux liquid in the distillation towers has to removed and released into the sea in order to prevent condensation. This is
how we are trying to minimize the amount of DMAc that is released into the sea, thereby reducing its potential impact on aquatic ecosystems. We measure and evaluate thesuccess of our efforts based on the amount of potentially hazardous chemicals released into the environment.
Water pollutant category
Microplastics and plastic particles
Description of water pollutant and potential impacts
There is a growing concern that microplastics in the ocean attract persistent organic pollutants (POPs) such as polychlorinated biphenyls (PCBs), are picked up byplankton, which are then eaten by fish, and finally end up in the human food chain and affect our health. It is feared that these POPs are carcinogenic and endocrinedisrupting, but the complexity of the behavior of microplastics in the environment and how POPs are accumulated in marine species makes it challenging to estimate thescale and magnitude of the impact. That said, if a lot of POP-contaminated microplastics end up in the human food chain, the impact on our health could be huge, given thehigh bio-accumulation potential of POPs. Microplastics could result from chemical plants and from inappropriate disposal of end-of-life plastic products. The Asahi Kasei
Group is trying to tackle this issue as a producer of plastic products.
Value chain stage
Direct operations
Actions and procedures to minimize adverse impacts
Procedure(s) under development/ R&D

The Asahi Kasei Group is trying to tackle this issue within our sphere of responsibility and influence. Specifically, we are trying to minimize our impact both as a producer ofplastic products and as a generator of plastic waste. We, for example, are actively working to reduce single-use plastics, promote the 3Rs (Reduce, Reuse, Recycle)
activities in all of our business areas, and are also trying to eliminate landfill of plastic waste. The success of our efforts will principally be evaluated based on the status ofdevelopment of such products and the amount of plastic waste landfilled.

W4. Risks and opportunities

W4.1(W4.1) Have you identified any inherent water-related risks with the potential to have a substantive financial or strategic impact on your business?
Yes, both in direct operations and the rest of our value chain

W4.1a(W4.1a) How does your organization define substantive financial or strategic impact on your business?
To us, “substantive financial or strategic impact on our business” means any significant impact on our plants’ operations, financial performance or the relationship between
us and our stakeholders. For example, if a severe drought or flood should hit an Asahi Kasei plant or any of our major suppliers, our operations could be disrupted, whichmight significantly affect our financial performance, and if any of our plants should release hazardous substances into rivers or the sea, affecting people’s health or the fishingindustry, it could significantly damage our relationship with stakeholders. Therefore, the definition not only applies to impact resulting from our own operations but also impact
resulting from suppliers’ operations. It is not always easy to estimate in advance the magnitude and probability of such adverse events, and it is almost impossible to quantify
the impact of a decline in stakeholder trust. But because an issue with a potential loss of billions of yen would be discussed by the Board of Directors, this could beconsidered as a threshold that indicates substantive change. At the Asahi Kasei Group, each of our plants has individually assessed water risks by monitoring trends in laws
and regulations applicable to water issues, and communicating with local stakeholders such as local communities, farmers, fishermen and local governments, for example.
Apart from this, we conduct a group-wide water risk assessment using WRI Aqueduct. Assessment results (risk levels) of Aqueduct are given in 5 levels: Low, Low to
medium, Medium to high, High, and Extremely high, but we do not use the assessment results of Aqueduct as they are. We make adjustments with information obtained fromindividual plants to arrive at the final assessment results. Basically, we use the adjusted risk levels (Low, Low to medium, Medium to high, High, and Extremely high) as anindicator, and we understand that there is a high possibility that substantive impact will likely occur when the adjusted risk level is High or Extremely high.

Company-specific description
Products produced at our two plants in Singapore are some of essential building blocks of the ‘Materials’ field in our Medium-term management initiative “Be a Trailblazer”
aiming to contribute to a sustainable society. Therefore, the operational stability of the two plants in Singapore is very important for the Asahi Kasei Group’s business plan.
Chemical plants require a lot of water especially for cooling, but Singapore chronically suffers from water shortages because of its small land area and lack of large rivers.
Good quality water is being supplied from neighboring Malaysia, but a change in political or other circumstances could lead to instability in water supply. Lobbying activities
might become more important and much more care will have to be taken when choosing locations for further expansion of plants.

We also used unit prices for all the products included in relevantbusinesses for confidential reasons. Our estimation of the impact is about 0.37% of the Asahi Kasei Group's sales.
Primary response to risk
Improve monitoring
Description of response
To collect information and intelligence is always the first step in running a good business, regardless of whether it is about water risks or not. We understand that Singapore
is a country where environmental regulations are likely to be strengthened quickly. The carbon tax introduced in Singapore in 2019 is just one such example. We recognizethat collecting and analyzing information and intelligence are the basic steps for detecting and minimizing water risks. Specifically, we offer Microza, a hollow fiber filtration
membrane for water treatment, to the Changgi New Water Plant, Singapore’s largest sewage recovery plant. Based on such achievements, there is a close connection to
the Singaporean Ministry of Sustainability and the Environment, and information on water administration in Singapore (such as water price trends, water self-sufficiency rate
improvement plans, and trends in Malaysia, which is a water import destination) can be obtained in a timely manner. Furthermore, information on the Ministry of
Sustainability and the Environment’s website and external information providers is monitored at all times. In addition, with regard to water-related regulations, lobbying
activities are carried out domestically and overseas through JCIA (Japan Chemical Industry Association).

Explanation of cost of response
No observable cost is incurred by information and intelligence collection because this is inseparable from what we do in the normal course of business. We believe that any

Company-specific description & strategy to realize opportunity
The global market for microfiltration (MF) and ultrafiltration (UF) systems is growing by about 10% annually, driven by serious environmental water quality issues and water
shortages, as well as increasingly stringent global wastewater regulations. Microza holds the leading share of the US market for membrane-process water clarification
systems, the world’s largest market for such systems. We consider this opportunity strategic because the adoption of Microza has been growing firmly in many countries
that face water shortages and have growing needs for improved water quality. In fact, we are trying to shift our focus away from the traditional Japanese and US markets
towards countries that face water shortages such as China, Korea, Singapore, Thailand, Indonesia, and Middle Eastern countries. For example, in 2017, Microza wasselected for a desalination plant in Kuwait, whose treatment capacity is scheduled to be 610,000 tons per day, representing the largest hollow-fiber filtration membraneorder received by Asahi Kasei. Asahi Kasei has contributed, and will continue to contribute, to solutions for a wide range of environmental problems related to water
resources by achieving further growth in orders for large-scale water-treatment facilities throughout the world, particularly in Asian countries where the number and scale ofsuch projects is forecasted to increase steadily.

Executive
Officer(CEO)

The ultimate responsibility for water-related issues in the Group lies with the CEO.
In our group, water-related business is one of the most important management issues in terms of risks and opportunities for our business. In terms of risk, many of our Group’s plants are located inareas with abundant water resources, but some factories have the risk of depleting water resources, which could have a major impact on factory operations when risks materialize. We recognize that
not only current factory responses, but also decisions on future locations are important management issues. In addition, the Board of Directors is also discussing analyses and responses based on the
TCFD framework, such as considering necessary responses, assuming the possibility of flooding and the leakage of hazardous materials as weather disasters become more severe due to climatechange. On the other hand, from an opportunity perspective, we are considering measures to contribute as a business in anticipation of a shortage of water resources and the increasing uneven
distribution of water resources worldwide. These are reflected in the content of the medium-term management plan and the annual management plan that the CEO takes the lead in formulating.
Decision-making example:
The budget allocation for upgrading and repairing wastewater and wastewater treatment facilities in Singapore, Kawasaki, Fuji, and other locations in 2022 was approximately 1.4 billion yen. The
decision-making process for this investment was comprehensively led by the CEO.

This is especially true in the field of sustainability, which was not been given sufficient importance in thepast. In addition, rewards can be set according to individual performance, which stimulates the
motivation to work within the company.
Performance-linked remuneration, which constitutes a part of remuneration for executive directors, shallbe calculated based on the degree of achievement of the Group's consolidated financial indicators, suchas net sales, operating income, and ROA, as well as a comprehensive judgment based on the degreeof achievement of individually established targets, including the promotion of sustainability (ex. waterrelated measures).

The Asahi Kasei Group’s Vision aimed for “the pursuit of healthy and comfortable lifestyles” and “coexistence with the environment.” “Be a Trailblazer”, a three-year medium-term
management plan launched in FY2022, expresses the Group’s stance of contributing to the sustainable development of people and the planet in the future as “Care for People,
Care for Earth (thinking about people and the planet).” This is an indication of the Asahi Kasei Group’s approach to sustainability.
Based on this belief, the Asahi Kasei Group has identified “Promotion of Environment-Contributing Businesses” and “Prevention of Water Pollution” as materiality and is
implementing various initiatives. For example, we aim to promote the recycling of sewerage and factory wastewater using hollow fiber membrane filters and the UVC (deep UVC)LEDs, which we have recently developed as an environmentally friendly device to replace Hg lamps, through our business in China and India, where industrialization isaccelerating, or in the Asian region, where the population is rapidly increasing. In this way, we believe that providing state-of-the-art technology and providing clean and safe
water to people living in areas where there are concerns about deteriorating water quality will lead to the realization of our Group Vision.

According to OECD Environmental OUTLOOK2050 Report, if countries around the world do not engage in more ambitious environmental measures, the number of people
suffering from severe water shortages will increase by 2.3 billion in 2050 (approximately 40% of the world’s population).
In addition, global water demand is reported to increase by 55% for industrial use. In addition, according to another report, the world membrane market is expected to grow by
CAGR9.0% through 2019 and 2024 in. By region, the Asia-Pacific region, which is experiencing rapid economic growth (particularly China, India, Indonesia, etc.), is a promisingmarket.
We have already formulated a business strategy based on the above trends, and believe that we can enjoy the long-term business benefits of being a hollow fiber filter top
company.

Financialplanning

According to the ASDReports report “UV Sterilization Market, Global Forecast to Year 2023”, the UV fungicide market will grow by an CAGR13 of 7% in 2017-2023 to reach $4.27
billion in 2023 due to rising demand for safe drinking water in developing countries and increased demand for environmentally friendly fungicidal systems.
Under such circumstances, we have newly developed a deep UV UVC-LED “Klaran” that can emit light at wavelengths around 265 nm with high power that can effectively performsterilization. Using this device, drinking-water can be disinfected more easily, saving people suffering from water-borne illness in developing countries and elsewhere.
In addition, since this device does not use any mercury, it can also respond to international mercury use regulations, and it is highly expected to be a light source instead of
mercury lamps.
Research, application development, and sales expansion costs for this business expansion have already been reflected in financial planning.
The Asahi Kasei Group as a whole has prepared a budget of 800 billion yen for investment including this device business expansion.

In the next fiscal years, the water purification business using UVC (deep UV)-LEDs is also expected to expand, and the amount of R&D investment is expected to increase.
OPEX:
Most of the operating expenses in 2022 were for water quality analysis of wastewater discharged directly into public waters, such as rivers and the sea, and the cost of its
neutralizing agents, many of which were used to comply with laws and regulations. As there were no major changes in the number of business establishments analyzed forwater quality, the change compared to the previous year was 5.79%.

We use currently the TCFD framework to determine the risks and opportunities of our company and how those could have substantive financial or strategic impact on us. We suppose two
scenarios for the climate change and relevant social change, meaning IPCC SSP3-7.0 (+4°C) scenario and IEA NZE 2050 (+1.5°C) scenario. In IPCC SSP3-7.0 scenario, the temperature will rise
sharply in accordance with the strengthening typhoons that have heavier rain and stronger wind. In IEA NZE 2050 scenario, the temperature will rise moderately with more strict regulations on CO2emission and policies that promote more climate-friendly options, such as electric vehicles. We have discussed the impact of both risks and opportunities with people from our three core businesssectors, and the corporate division. After this discussion, we had a more comprehensive discussion at the corporate strategy committee meeting and the board meeting to determine the risks andopportunities including water-related issues.

Participation in various workshops and seminars deepened the understanding of the costs of plumbing water. For example, we learned that much of the water we use at
our sites is costly to treat for chemical substances that contaminate it during overheating, cooling, and wastewater management, so the cost is up to 40 times higher per
