2025 Activities and
Environmental Data

Based on our environmental policy, the Kumon Group is promoting activities to identify and reduce the environmental impact of its business activities, as well as to promote forest conservation.

In FY2025, the Kumon Group as a whole continued to reduce electricity and paper consumption, and increase the amount of recycled paper as basic actions related to the environment. As a result, environmental data for the entire Kumon Group in FY2025 were 93.2% for electricity consumption, 91.9% for paper consumption, and 89.0% for paper recycling compared to FY2024.

In Japan, we are promoting “Work Style Creation" as an initiative to realize diverse work styles, value creation, and productivity improvement for all staff. As part of this initiative, we have digitized documents and streamlined operations, resulting in a significant reduction in paper usage. In addition, remote work has taken root, leading to reductions in electricity and paper consumption.

The reporting period is FY2025 (April 1, 2025, to March 31, 2026). However, some of the environmental data and activity information included in this report fall outside this period.

Kumon-operated Centers are not included.

Electricity Consumption

The Kumon Group is promoting the reduction of the usage of electricity to reduce the production of greenhouse gases in order to slow global warming.

We engaged in many daily activities such as adjusting air conditioning temperatures, turning off lights in areas that are not being used, and setting personal computers on energy-saving mode.

Compared to FY2024, electricity consumption decreased in FY2025. North America achieved a 15.4% reduction, Asia and Oceania achieved a 7.8% reduction, and Japan a 4.6% reduction. These reductions were due to the proactive efforts by each group company to switch to LED lighting and update air conditioning systems, as well as the implementation of remote work and office reorganization.

The Kumon Group as a whole reduced electricity consumption by 6.8%.

We will continue to promote energy-saving activities.

Year	2021	2022	2023	2024	2025
Electricity consumption (MWh)	9,349	8,632	8,299	7,974	7,431
Y/Y(%)	94.9	92.3	96.1	96.1	93.2

CO₂ Emissions

The majority of greenhouse gases emitted by the Kumon Group are generated by electricity usage. Therefore, we work on the reduction of our CO₂ emissions by promoting the reduction of our electricity usage.

Compared to FY2024, the Kumon Group reduced its total CO₂ emissions by 9.1% and its CO₂ emission intensity (CO₂ emissions per unit of net sales) by 11.6% in FY2025 .

* For CO₂ emission factors, within Japan, we use the emission factors for the most recent fiscal year from the “List of Emission Factors by Electric Utility Operators” published by the Ministry of the Environment and the Ministry of Economy, Trade and Industry. For overseas locations, taking into account data availability and the continuity of calculation methods, we have been using the five-year average of the emission factors for 2018–2022 from the “Emissions Factors” published by the IEA (International Energy Agency) since fiscal year 2025.

Year	2021	2022	2023	2024	2025
CO2 emissions (t-CO2)	4,237	3,819	3,685	3,491	3,174
Y/Y(%)	94.3	90.1	96.5	94.7	90.9

Paper Consumption

As the Kumon Group uses a large amount of paper for worksheets, etc., we promote the reduction of paper usage to preserve forest resources.

We have been promoting the digitization of documents, paperless meetings, printing on both sides of paper, and compact usage of paper, etc.

In addition, paperless operations have been advanced due to the increase in teleworking, digital reporting, and the digitization of FAXs etc.

Furthermore, the Kumon Group is expanding the use of environmentally friendly FSC-certified paper.

Compared to FY2024, paper consumption in FY2025 was reduced by 11.9% in North America, 13.9% in China, and 12.1% in Japan.

The Kumon Group reduced its paper consumption by 8.1% and its paper consumption intensity (paper consumption per unit of net sales) by 10.7% in FY2025.

• *Paper purchase volume calculated as paper usage volume

Year	2021	2022	2023	2024	2025
Paper consumption (millions of sheets)	13.8	11.8	10.0	9.8	9.0
Y/Y(%)	78.2	85.7	84.2	97.9	91.9

Paper Recycling volume

Each Kumon Group company promotes recycling by placing paper recycling boxes to collect used copy papers as much as possible.

In Japan, unwanted materials are regularly collected and recycled at the head office.

Compared to FY2024, the Kumon Group’s paper recycling volume decreased by 11.0% in FY2025.

Year	2021	2022	2023	2024	2025
Paper recycling volume (t)	789.5	900.0	816.6	755.8	672.5
