CO₂ Emissions

We have set "Conserving resources and energy, and promoting the introduction of renewable energy" as a key materiality action plan. The plan includes a KPI of reducing domestic CO₂ emissions by 50％ or more by fiscal 2030 compared to fiscal 2013, and we are proactively working toward achieving this target. Concrete measures undertaken by Maxell Group as part of plant electricity-saving measures include visualizing electricity consumption patterns to reduce wasteful electricity usage, improving operational efficiency through demand management at facilities, updating air conditioning systems, switching to LED lighting, and planting of green walls. In fiscal 2022, the Kobuchizawa Works, Kyoto Works, and Ono Works began solar power generation for in-house consumption. In fiscal 2024, the Kobuchizawa Works generated 164 MWh, the Kyoto Works generated 261 MWh, and the Ono Works generated 717 MWh. We also started purchasing non-fossil certificates in fiscal 2022. As a result of these initiatives, we achieved our KPI of "10％ domestic renewable energy ratio by FY2030" already in fiscal 2022, and we therefore have revised the KPI to a more ambitious target of 15％.

Our domestic CO₂ emissions in fiscal 2024 dropped by 2％ from the previous year, while overseas emissions dropped by 6％, leading to an overall drop of 3％ across the Group as a whole (down 43％ compared to fiscal 2013). In the future, we will continue to reduce electric power through energy-saving activities, introduce solar power generation for in-house consumption, and increase our percentage of non-fossil certificates. In addition to solar power generation for in-house consumption, the Ono Works is also selling electricity generated with its solar power facilities. In fiscal 2024, 1,344 MWh of electricity was generated for this purpose, contributing to the prevention of global warming.

Reduction of CO₂ Emissions Including Scope 3

Maxell Group calculates total CO₂ emissions across the entire supply chain, including Scope 3 emissions. Scope 3 emissions refer to indirect emissions other than Scope 1 and Scope 2 emissions. For emissions calculations, starting from fiscal 2018, we aggregate and disclose performance data in accordance with the "Basic Guidelines on Accounting for Greenhouse Gas Emissions Throughout the Supply Chain" issued by the Ministry of the Environment and the Ministry of Economy, Trade and Industry.

Energy Intensity per production

Transport-related Energy Intensity Per Production

Since Maxell Group offers a wide range of products, we monitor the transport-related energy intensity per production at each manufacturing base.
In fiscal 2025, the total figure for all manufacturing bases increased by 5％ compared to the previous fiscal year.

Waste Reduction and Recycling

With regard to conserving resources as part of our materiality action plan, our recent focus has been on measures for waste plastic as an environmental issue, and we are investigating chemical/materials recycling. Furthermore, at Maxell Group, we are working toward "Zero emissions"*1 by ensuring thorough waste separation, promoting the monetization of valuable waste through information sharing across business sites, and expanding and enhancing in-house intermediate processing.

For example, in the lithium-ion battery electrode manufacturing process, we separate paint residue and end cuts generated in each production step, and deliver these to appropriate companies to recycle copper, aluminum, and rare metals such as cobalt (102 tons in fiscal 2025).In the primary battery manufacturing process, in addition to the conventional recovery of silver oxide (2.3 tons in fiscal 2025), we have begun recovering zinc (0.5 tons in fiscal 2025) and copper (0.02 tons in fiscal 2025) since the previous fiscal year, thereby strengthening resource recycling. The amount of valuable waste generated domestically in fiscal 2025 increased by 35% compared to the previous fiscal year.As a result of our intensified recycling efforts, domestic manufacturing bases achieved zero emissions for the 25th consecutive year.

Water Consumption Reduction Initiatives

Maxell Group strives to reduce water consumption in manufacturing processes and conserve water resources through reutilization and other practices. For instance, at the Kyoto Works, a system to recover and reuse 100％ of drain water was introduced in response to increased steam usage due to the increased production of lithium-ion battery electrodes. This resulted in a saving of 40 thousand m³ of water annually.At domestic Group business sites, water usage decreased by 6% compared to the previous fiscal year, while at overseas Group business sites with high water risk*2, it decreased by 32%. Overall, water consumption in the Maxell Group decreased by 10% compared to the previous fiscal year, mainly due to the sale of a plant in China that produced Prismatic Lithium-ion Rechargeable Batteries.

Business Activities in Water-Stressed Areas
Maxell's overseas group factories are located in China (2 sites), Malaysia (1 site), and Indonesia (1 site). According to the Water Risk Atlas (Aqueduct), these four sites face higher water risks, including baseline water stress and flood risk, compared to domestic sites. Consequently, these overseas factories set annual targets for water consumption intensity and actively work on reducing it.

Chemical Substance Management During Production

The Maxell Group manages and strives to reduce the amount of chemical substances handled, emitted, and transferred during the manufacturing process.

Environmental Fines and Penalties in Fiscal Year

In 2017, our factory in China received administrative guidance and a fine for exceeding wastewater pollutant concentration standards. Since then, we have installed wastewater treatment facilities and have had no further issues. Learning from this experience, we have implemented sufficient measures to prevent legal violations, and no violations have occurred to date.
