Environmental Management System

Our environmental management system conforms to ISO 14001 standards. The environmental management system is controlled by the Quality and Environmental Management Committee, established under the CSR Committee chaired by the President and Representative Director, and applies to all of POC’s business activities (construction activities and business activities in our offices).
We formulated the "Integrated Manual" that outlines the rules and procedures for corporate management in conformity with the certified environmental management system and quality management system, and implement it across the organization. In addition, we continuously provide training sessions to employees, including management system training for young employees, to inform and educate our employees.

Operation of Environmental Management System

Certified as a company-wide system in November 2002
We will continue to utilize our management system in order to promote continuous system improvement and efficient and effective operations.

Environmental Patrols

We conduct environmental patrols at construction sites in each branch office to minimize environmental incidents such as air pollution, water pollution, soil contamination, noise, vibration, ground subsidence, and foul odors, and to ensure zero violations of environmental laws and regulations.

Compliance with Environmental Laws and Regulations

Companies today are required to manage their business activities in an environmentally conscious manner in all aspects, including initiatives to fight global warming and waste management, and must ensure continuous compliance with environment-related laws and regulations. We strive to prevent violations of environmental laws and regulations by promptly undertaking recent revisions of all laws and regulations, such as the Air Pollution Control Act, the Law Concerning the Discharge and Control of Fluorocarbons, and the Soil Contamination Countermeasures Act.

Environmental Education

Specialized environmental training

We provide specialized environmental training to keep all employees apprised of the necessary knowledge of overall environmental management at construction sites and the key points of legal revisions. The specialized environmental training is provided every year at the headquarters office and branch offices, and we ensure employees’ participation on a regular basis (once every three years). In FY3/23, 619 people took the specialized environmental training. In FY3/23, we conducted environmental training targeted for the employees in sales & marketing and design engineering divisions at the headquarters to enhance their knowledge level of compliance to environmental laws and regulations when dealing with clients, and 233 employees attended the training.

Technical environmental training

We conducted specialized environmental expert training for employees of the Environment, Health, Safety and Quality Divisions Group at branch offices to provide them with more far-reaching knowledge. Through this training, we aim to strengthen their perspective during the branch patrols and further enhance the training of construction staff.

Indicators and Targets

Environmental Targets

Based on our "Environmental Policy," we set annual "company-wide environmental targets" based on past activity results and annual business plans, and develop environmental activities to achieve these targets.

Environmental Preservation Costs

Since FY2000, we have been disclosing our environmental preservation costs as an effective means of disclosing accurate information on the status of our environmental preservation initiatives, in order to ensure the efficient implementation of environmental preservation activities and to make the most of our environmental management.

Basic items and calculation method

The environmental conservation costs are calculated according to our calculation standards based on the "Environmental Accounting Guidelines for the Construction Industry 2002" (published by the three associations: Japan Federation of Construction Contractors, Japan Road Contractors Association and Japan Dredging and Reclamation Engineering Association) and the "Environmental Accounting Guidelines 2005" (published by Ministry of the Environment).

  • Business area costs are calculated based on costs incurred at work sites only.
  • Upstream/Downstream costs, R&D costs, and social activity costs are calculated only for costs incurred in indirect divisions groups, such as headquarters and branch offices.
  • Management activity costs and environmental damage costs are calculated as the sum of costs incurred at work sites and indirect divisions groups.
  • Costs for work sites are estimated based on the figures from the sample sites excluding overseas projects and the amount of work completed during the period.
  • Indirect costs were calculated for all headquarter offices and branch offices (including sales offices), excluding those incurred in overseas offices.
  • The number of work sites sampled was 33 for civil engineering projects and 14 for building construction projects, for a total of 47.
