Status of environmental management system

Haseko Corporation, HASEKO REFORM, and Fujikensetsu Co., Ltd. have obtained ISO 14001 environmental management system certification and they are continually managing and improving its environmental activities.

Background to obtaining ISO certification

The Company obtained ISO environmental management system certification in the Kansai and Tokyo regions in July 2001 and October 2001, respectively. In October 2013, we integrated the environmental management systems in Tokyo and Kansai regions and have since been operating the integrated system. As of April 2024, approximately 98% of Haseko Corporation’s offices have obtained the ISO14001 certification. Haseko Reform, Inc. obtained ISO14001 environmental management system certification in March 2014 (at Tokyo and Kansai branch offices). In April 2018, the system was updated to the 2015 version and integrated with the ISO9001 quality management system, and the integrated system has since been in operation. In addition, Fujikensetsu Co., Ltd. also obtained ISO14001 environmental management system certification in December 2020 for its Kansai Branch and February 2021 for its Tokyo Branch.
Going forward, we will continue to engage in environmental management activities.

Initiatives and ongoing improvement

Upon conducting environmental preservation activities, we formulate Environmental Policy, in response to which each division sets environmental goals and numerical targets and carries out the activities accordingly.

The environmental management system is checked by internal audit and external examination as to whether or not it complies with Haseko's determinations including specification requirements, and whether or not it is implemented and maintained properly. Based on the results, the environmental management system is reviewed and improved on an ongoing basis.

The days on which external examination was conducted and the number of matters pointed out in fiscal 2023 were as follows.
