Environmental Performance
By providing solutions that contribute to the global environment and a rich life and working to reduce environmental impacts and disclose timely information in fundamental business domains, Kaneka Group engages in various environmental initiatives.
Material Balance
Kaneka Group is working to reduce environmental impacts by aggregating the status of energy and resource inputs and material outputs through emissions and products to grasp production activity volume, targeting Kaneka and Group companies within Japan and overseas.
For data of indicators related to climate change and environment protection, we have received third-party assurance to ensure the reliability and transparency of Data Sheet 2024.
For indicator data, some calculation methods have been changed. For details, please refer to “Calculation Methods for Data of Indicators related to Environment”.

Environmental Accounting
We efficiently and effectively promote environmental conservation activities by quantitatively grasping the investment and expenditure costs related to environmental conservation and the quantitative and economic impacts of environmental measures. We calculate these costs and effects based on the 2005 edition of the Environmental Accounting Guidelines by Japan’s Ministry of the Environment with Kaneka’s own unique way of thinking, targeting all parent manufacturing sites and 30 Group companies in Japan (manufacturing companies).

Environmental Investments (Kaneka)
We continue to invest in environmental conservation.
Environmental investments in fiscal 2023 totaled 1,011 million yen.
Environmental investment over the past five years averages about 1,600 million yen, leading with water quality (54.3%), followed by air quality (30.5%) and the work environment (8.4%). We will continue to invest proactively to maintain and improve the environment.

Environment Efficiency (Kaneka)
Kaneka assesses the environmental impact of our production activities using Environmental Impact Points (EIPs), which are compiled using the JEPIX methodology, and we use these points to assess our environmental efficiency.
Our total environmental impact for fiscal 2023 amounted to 4.11 billion EIPs, a 0.3% increase from the previous year. This was primarily due to a rise in greenhouse gases and phosphorus, despite reductions in hazardous air pollutants, NOx, SPM10, and nitrogen. Environmental efficiency deteriorated by 0.9% compared to the previous year.

CHECK & ACT
Under environmentally friendly management, we continue working to reduce environmental risks by complying with environmental regulations and legislation and criteria in agreements with local governments and by checking compliance with them through various means, including ISO 14001 internal audits and ESG safety and quality inspections.
We will also continue working to further reduce environmental impact and improve environmental efficiency by visualizing greenhouse gas emissions and promoting energy conservation activities.
TOPICSGreen Bond (Environmental Bond) Issued
As its 7th unsecured straight bond, Kaneka issued a green bond (environmental bond) to procure funds for the manufacture and R&D of KANEKA Biodegradable Polymer Green Planet™ (“Green Planet™”) in September 2019. A green bond is an ESG bond, and fund usage is limited to projects that contribute to resolving environmental issues. It is the first such industrial bond issued by a Japanese chemical company.
Green Planet™ is a 100% plant-based material derived from microorganisms that consume plant oils and store them as polymers within their bodies. Biodegradable in seawater and soil, it is expected to help solve the global issue of marine pollution caused by microplastics.
For the issuance of the green bond, Kaneka has established the Green Bond Framework, which conforms to the Green Bond Principles 2018 of the International Capital Market Association (ICMA) and the Green Bond Guidelines 2017 Edition of Japan’s Ministry of the Environment. To obtain eligibility for and transparency of this green bond and raise its appeal for investors, as a third-party evaluation, Kaneka has obtained a second opinion from Rating and Investment Information, Inc. (R&I) of how this framework conforms to the Green Bond Principles 2018 and the Green Bond Guidelines 2017 Edition. Kaneka has also obtained top-level evaluation in the green bond assessment by R&I, the GA1 preliminary evaluation.
The relevant business segments of the green bond principles and the relevant development objectives of the SDGs are shown in the table below.
