Chiyoda Corporation became Japan's first engineering and construction company to acquire ISO14001 certification for environmental management in March 2001, and strives to upgrade the Corporate SQE Policy and management system it has instituted while conducting systematic environmental education and awareness activities.

Environmental Management System (EMS)

At Chiyoda Corporation, the SQEI Management Committee, which is part of the Management Committee, is responsible for decisions on environmental activities. This committee establishes Corporate SQE Policy and periodically reviews the Company's activities. In addition, the Company has established committees under the direct control of top management to promote occupational safety, health and environmental (HSE) activities. Lower-level committees at each operating base promote independent initiatives in the categories of office activities, R&D activities and EPC* activities.
Moreover, to counter global warming, the Company has established the Global Warming Countermeasures Working Group, which is under the Management Committee and comprises the general managers or the section managers of the related Units commencing with the Corporate Services Unit. The working group’s initiatives to reduce office greenhouse gas emissions include formulating countermeasure plans and auditing the status of plan implementation.

All departments and locations undergo the audits in writing every year and are audited by interview every three years.
The audits also include the response taken to the issues raised by a third-party inspection organization.

Environmental Activity Categories

Chiyoda Corporation’s main operations are in the engineering, procurement and construction (EPC) of plants/facilities, project management with the related support services and research and development. We categorize these operations into EPC, Office and R&D activities, as shown in the figure below, which also correspond to our environmental activity categories.

Chiyoda Corporation have set environmental or HSE objectives for the three areas of EPC, office and R&D. In addition, in Japan and overseas we contribute to the environment through our core business and monitor environmental impact at construction sites and offices while energetically undertaking environmental activities such as promoting recycling and green procurement.

Environmental Activities

EPC Activities

Chiyoda Corporation establishes annual environmental objectives(HSE objectives) for each of its specialized engineering and procurement departments based on the environmental objectives shown below. Self-evaluations of performance at the end of the first half and the full fiscal year are applied to the following fiscal year's activities.

<EPC Activities toward Environmental Objectives(HSE Objectives) in the Fiscal Year Ended March 2017>

Objective 1 -- Acquire Customer Satisfaction with Environmental Proposals
Made an average of 1.7environmental proposals per project in Japan and overseas.

Objective 2 -- Improve project efficiency by reducing industrial waste
The ratio of final landfill quantity to initial disposal quantity for construction sites in Japan during the fiscal year ended March 2017 was 9.3 percent. This is well explained with reasons that a high volume of insulation waste, debris and other hard-to-recycle waste such as glass and ceramics was emitted due to demolition of existing plant facilities in addition to the incineration or landfill disposal of a large quantity of plastic waste in outlying regions.

  • Note: Starting from the fiscal year ended March 2011, residue after incineration is estimated at 7 percent of pre-incinerated waste volume and added to final landfill quantity.

Material Flow

Material flow in business activities for the fiscal year ended March 2017 is shown below.
