Environmental Management

Environment Management System (EMS)

We have developed and are operating a company-wide environmental management system (EMS). By 1999, we had obtained ISO 14001 certification for our EMS at all sites.

See the website of the Japan Accreditation Board (JAB) for the status of ISO 14001 certification.

Environmental Management Promotion Framework

Under the Business Plan Committee mandated by the President, we have established the Environmental Management Expert Committee chaired by the executive officer responsible for the environment. It develops strategies and policies on Obayashi's environmental management and strives for continual self-improvement by reviewing targets and initiatives based on the evaluation results of its environmental management system (EMS). The environmental departments in the Head Office, main offices, branches, and Group companies drive Obayashi's environmental efforts and take concrete actions based on the plans and targets set by the Environmental Management Expert Committee.

Compliance with Environmental Laws and Regulations

A construction business must comply with numerous environmental laws and regulations. At Obayashi, environmental compliance is more than just following environmental laws and regulations. We set higher standards for ourselves and respond appropriately based on these. Environmental law and regulation supervisors are appointed at branches throughout Japan to respond to inquiries from construction works offices and the like. We also give online courses and group trainings to raise knowledge and awareness of environmental laws and regulations.


Environmental Education and Awards

We designate June 1 to June 7 every year as Environment Week. The purpose of this is to raise awareness of the environment among all officers and employees across our group and to further promote environmental conservation activities. We undertake various initiatives during this week. These include providing e-learning courses, holding seminars with industrial waste intermediate treatment companies and running environmental patrols.

Supply Chain Initiatives

It is essential to grasp and assess risks for environmental issues and to then undertake initiatives in our supply chain to promote environmentally-friendly business activities. In March 2020, we revised the CSR Procurement Guidelines we enacted in June 2011 as the Obayashi Group CSR Procurement Policy. Under this policy, we are steadily promoting initiatives in our supply chain. In particular, we monitor construction sites for items with a large impact on our environmental burden (e.g., CO2 emissions, water usage and resource recycling). We are striving to reduce that impact together with our supply chain.

Global Warming Report

It is an obligation in Tokyo to submit a report including status of energy saving initiatives of each office, when energy emission, such as electricity, gas, fuel, of total offices in Tokyo exceeds 3,000kl per year converted to crude oil. We submit our report to the Tokyo Metropolitan Government Bureau of Environment due to this system, and it can be found on their website.
