Contribute to the Realization of a Decarbonized Society
We contribute to the realization of a decarbonized society in the overall supply chain by developing and providing solutions that help reduce GHG emissions in industries and society and by implementing low-carbon business activities.
The Kurita Group Approach & Contributions Through Our Businesses
The Kurita Group views climate change issues, including extreme weather events and natural disasters caused by global warming, as a major global social challenge, and will contribute to the realization of a decarbonized society throughout the entire supply chain by developing and providing solutions that contribute to the reduction of GHG emissions in the industry and society, and by implementing low-carbon business activities.
Regarding our efforts to address climate change issues, we disclose information on our response to climate change based on the recommendations of the Task Force on Climate-related Financial Disclosures (TCFD)*.
- Task force on climate-related financial disclosures established to examine how climate-related information should be disclosed, and how financial institutions should respond. The task force recommends companies disclose items related to climate change-related risks and opportunities. The task force dissolved in October 2023, and its supervisory function for the corporate climate change-related disclosure was taken over by the International Sustainability Standards Board (ISSB).
Contribution to Achieving the SDGs
Promotion and Governance System
The Kurita Group has identified contributing to the realization of a decarbonized society as one materiality issue. We strive toward the metrics and targets set by the department in charge, while the Sustainability Committee, chaired by the Corporate Officer and the Executive General Manager of the Sustainability Corporate Strategy Division, oversees and promotes Group initiatives. We have also established subcommittees dedicated to each shared value theme under the Sustainability Committee. One such subcommittee strives to strengthen initiatives aimed at achieving the metrics and targets, including exploring business opportunities that contribute to reducing Scope 3 and GHG emissions. The Executive Committee generally receives reports from the Sustainability Committee twice a year on the progress of these initiatives to discuss and approve any necessary measures. The Board of Directors then receives reports on this progress from the Executive Committee to fulfill its duty in overseeing all materiality initiatives. As an advisory body to the Board of Directors, the Sustainability Advisory Council deliberates on ideal medium to long-term sustainability management for the Kurita Group. These discussions consider the perspective of each stakeholder based on sustainability efforts ongoing worldwide. The Sustainability Advisory Council presents its findings and advises the Board of Directors about materiality initiatives.
(As of April 1, 2025)
To address environmental issues that we share with society, the Company also put in place the Kurita Group Environmental Policy. We launched an environmental management system that operates according to this policy and drafted manuals to promote environmental action. The Kurita Group constantly encourages these initiatives as environmental improvement activities*.
- The Kurita Group defines its environmental improvement activities as follows:
1. activities to comply with the environment-related laws and regulations of each country and region that are applicable in conducting business activities;
2. initiatives to solve international issues related to the sustainability of water and the environment through business activities; and
3. disclosure of information related to 1 and 2, and engagement with customers, business partners,
employees, shareholders and investors, and local communities related to such activities.

Evaluation of Results and Outline of Activities
The Kurita Group strives to reduce its Scope 1, 2, and 3 greenhouse gas emissions in line with the Paris Agreement, based on our long-term goal of achieving “net-zero” greenhouse gas emissions. This target was set according to the methodology of the SBTi* and certified by the SBTi in April 2025 as a science-based target.
In the baseline fiscal year ended March 31, 2020, Scope 1 + 2 emissions accounted for approximately 1.4% of Kurita Group greenhouse gas emissions, while Scope 3 emissions accounted for approximately 98.6%. This means that reducing our Scope 3 emissions is key to tackling climate change for the Kurita Group.
- An initiative that encourages companies to set greenhouse gas emission reduction targets in line with scientific knowledge, with the goal of limiting global average temperature rises due to climate change to 1.5℃ compared to pre-industrial levels.

Rate of Reduction in Scope 1+2 Emissions
The Kurita Group actively promotes the adoption of renewable energy in order to reduce Scope 2 emissions (those caused by power generation), which account for the majority of our Scope 1 + 2 greenhouse gas emissions. Our primary effort for reducing Scope 1 emissions is switching our company cars from gasoline-powered vehicles to hybrid and electric vehicles.
In the fiscal year ended March 31, 2025, we successfully reduced our Scope 1 + 2 emissions to 50.2% of the baseline fiscal year ended March 31, 2020. This was achieved with the renewable energy we adopted during the previous fiscal year and renewable energy certificates.
Going forward, we will adopt more renewable energy and continue to promote the decarbonization of our company cars so that we can further reduce our greenhouse gas emissions.
Please see the ESG Data section for data on renewable energy installations and energy consumption.
Rate of Reduction in Scope 3 Emissions
62.6% of our Scope 3 emissions are Category 11 greenhouse gas emissions caused by the use of products that we sell (mostly rotary machinery such as pumps used for transporting water). In the fiscal year ended March 31, 2025, we worked to reduce our Category 11 and 13 greenhouse gas emissions. We did so by improving the design efficiency of water treatment facilities and the development and adoption of low-carbon technology for water treatment membranes, which account for about 60% of our power consumption. These efforts were promoted in conjunction with stakeholders in Japan and overseas, and have led to technical innovations for promoting low-carbon products.
We also reviewed the actual operation data of water treatment facilities and the adoption of renewable energy by our customers. This enabled us to reflect actual power consumption and greenhouse gas emissions in our performance data.
On the other hand, our Category 11 greenhouse gas emissions caused by the use of products that we sell increased. This was due to the extra procurement of pumps in order to deliver more water treatment facilities. Therefore, our Scope 3 rate of reduction stagnated at 5.3% compared to the fiscal year ended March 31, 2020. Moving ahead, we will continue to promote the adoption of low-carbon technologies in order to reduce Scope 3 emissions. We will also strive to improve our emission calculation methods by utilizing actual operation data and information on the renewable energy adopted by our customers.
Changes in Scope 1 + 2 and Sc ope 3 GHG emissions*

Example Initiatives
Carbon Footprint (CFP)* Calculation
The Kurita Group works to calculate CFP in order to help reduce greenhouse gas emissions at customer sites and throughout our entire supply chain. We do this by providing solutions that help reduce greenhouse gas emissions and visualizing the greenhouse gas emissions caused by the products in our supply chain.
In the fiscal year ended March 31, 2025, our chemicals became the first water treatment products in Japan to be certified by the SuMPO/Internal-PCR Approval System. The Japan Sustainable Management Promotion Organization (SuMPO) provides the SuMPO/Internal-PCR Approval System for the review and approval of internal CFP calculation rules. Going forward, we plan to utilize CFP calculations to help improve the competitive advantage of Kurita Group businesses.
- A carbon footprint is an indicator that shows the greenhouse gas emissions of products and services across their entire life cycle (procurement of raw materials, to manufacturing, transport, use, and disposal), converted to an equivalent CO2 value.
Please see the section below for more information about our approval from the SuMPO/Internal-PCR Approval System.
AI-based Optimization of Water Treatment Facilities
The Kurita Group uses artificial intelligence (AI) to optimize the operation of RO membrane facilities that incur particularly high-power consumption and running costs in water treatment based on past data. We promote it as part of the Meta-Aqua Project, which aims to simultaneously reduce these running costs and greenhouse gas emission, especially those caused by power generation. This initiative is currently implemented in regions such as Japan, China, and Singapore. We have confirmed that AI- optimized operation can reduce power consumption by about 10%.
