2022 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 FY2022, 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 FY2022 were 92.3% for electricity consumption, 85.7% for paper consumption, and 114.0% for recycled paper compared to FY2021.

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.

In addition, a large amount of old worksheets are generated when teaching materials are revised, and in FY2022 efforts were made to reuse old teaching materials. In the same fiscal year, we were able to collect old Japanese language teaching materials that had been revised and refashion them into welcome set bags that contain pamphlets and other materials given to prospective students. We will continue our efforts to recycle teaching materials.

Electricity consumption in FY2022 was reduced by 26.8% in Kumon Europe and Africa and 14.8% in Kumon Japan compared to FY2021 as a result of each group company's active efforts to switch to LED lighting and upgrade air conditioning systems, as well as remote work and office reorganization.

The Kumon Group as a whole reduced electricity usage by 7.7%. We will continue to implement energy saving activities.

We will continue to promote energy saving activities.

Paper Usage

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 FY2021, paper consumption in FY2022 was reduced by 21.0% in China and 20.4% in Japan.

The Kumon Group as a whole was able to reduce paper consumption by 14.3% and the basic unit (paper consumption/sales) by 20.3%.
