2021 Activities and
Environmental Data

At the Kumon Group, we promote the assessment and reduction of the environmental burden resulting from our business activities, and promote forest preservation in accordance with our Environmental Policy.

As basic environmental actions continuing on from FY2020 the Kumon Group made efforts to reduce its usage of electricity and paper and to increase the amount of paper put out for recycling.

In Japan, we are promoting workstyle creation as an initiative to realize diverse ways of working, value creation, and productivity improvement for all staff. As part of this initiative, we have been digitizing documents and improving work efficiency. This has led to a significant reduction in the amount of paper used. In addition, the increase in telework due to the spread of COVID-19 has also led to a reduction in electricity and paper consumption.

As a countermeasure against COVID-19, we introduced online study and sent masks and disinfectant to Instructors and Centers in Japan and overseas in an effort to control the spread of infection.

The reporting period is the FY2021 (April 1, 2021 – March 31, 2022), but the environmental data and activities also include data from outside this period.
