Formulation of Environmental Policy
To strengthen its environmental initiatives, Kumagai Gumi revised its former “Safety, Health, Quality, and Environment Policy” into a dedicated “Environmental Policy” in 2025, establishing a set of guiding principles for action. Beyond strict compliance with environmental laws and related regulations, the company is committed to addressing global-scale environmental challenges by reducing environmental impact and creating a better environment through its business activities.
Governance
Kumagai Gumi deliberates on key management issues, including issues related to the climate, at its “Management committee” (Chairperson: President). The “Sustainability Promotion Committee” (Committee Chair: General Manager of the Management Strategy Division) has also been established as a supporting body of the Management committee.
The “Sustainability Promotion Committee” comprises members such as General Managers of Business Divisions, and is an organization that examines overall measures contributing to long-term growth of the company and development of a sustainable society from the perspective of ESG and SDGs. It coordinates with the Management committee and other committees in order to tackle environmental challenges, including issues related to the climate, and to examine measures aimed at achieving environmental targets.
The Board of Directors (Chairperson: President) receives reports on climate change related matters obtained with the above process, and oversees the state of initiatives.
Risk Management
Kumagai Gumi is working toward identifying and reducing risks that affect business activities as well as maximizing opportunities, by isolating and assessing the risks and opportunities of important issues on an individual basis, and making decisions at the Management committee and Board of Directors. Each business unit extracts and evaluates risks and opportunities included in its work processes to examine required measures, and apply them to the annual plan. The state of these initiatives is monitored every quarter, with the results reported to the Management committee. Reports and discussions on environmental risks and opportunities, including those related to climate change, are made by the “Sustainability Promotion Committee,” which are in turn reported to and deliberated by the Management committee and Board of Directors.
Overview of Environmental Initiatives
In February 2021, the Kumagai Gumi Group joined the RE100 initiative, working to shift 100% of the electricity used in our business activities to renewable energy. We have obtained SBT certification as we work to achieve the targets for our medium- to long-term greenhouse gas emissions goals.
- CO2 emissions
Scope 1: Direct emissions from combustion of fuel (use of heavy machinery, vehicles, etc.)
Scope 2: Indirect emissions from the use of electricity, etc. supplied by other companies
Scope 3: Indirect emissions from upstream/downstream areas of business activities other than Scope 1 and 2 (materials procurement, operation of buildings, disposal, etc.) - Construction mixed waste discharge rate (%) = amount of mixed waste generated (t) (including the amount from demolition works, materials buried underground, and construction sludge) / total construction waste generated (t) (including the amount from demolition work, materials buried underground, and construction sludge)
- Electronic manifest use rate (%) = number of electronic manifests / (number of electronic manifests + number of paper manifests)
