Effluents and Waste (FY2018 Report)

Materiality Indicators

Management Approach

Reasons why materiality is important for our business

Over the entire business process, from drilling of natural gas to supply of city gas, the Daigas Group, as an energy business operator, sees it as important to promote more efficient use of natural resources based on the 3Rs (reduce, reuse and recycle) and to reduce the load on the environment in doing business.

Commitment

The Daigas Group is committed to promoting environmental activities on a group-wide basis by formulating “Daigas Group Environmental Activities Policy” and “Rules for Environment Management Systems” in line with related environmental laws.

(International and domestic standards)
  • ISO14001

Responsibilities

In the Osaka Gas, a unified environmental management system (EMS) based on ISO 14001 is deployed across the company under the supervision of the “CSR Executive” (Vice President), and all employees work to reduce the environmental impact of business activities and ensure that environment-related laws and regulations are complied with.

In addition, the Daigas Group's 56 domestic affiliates operate their own EMSs, such as ISO 14001, Eco Action 21, and the “Osaka Gas Environmental Management System (OGEMS).”

Environmental Management System (EMS)
EMS is a mechanism for achieving continual improvement by following the PDCA cycle of Plan, Do, Check, and Act.

Performance

Final disposal rate of industrial waste at overall Osaka Gas was 0.7% and it indicates that we are making steady progress toward achieving our target of 1.0% or less toward FY2021. From now on as well, we are strengthening 3R (Reduce, Reuse and Recycle) of waste materials.

Specific actions taken regarding materiality

Efforts at city gas manufacturing plants

Industrial waste is generated in the course of repairing/improving plants, while Osaka Gas endeavors to undertake eco-friendly construction work and to reduce industrial waste.

Efforts in gas fitting

For gas fitting, Osaka Gas seeks to curb the generation of roadway waste materials (excavated soil, asphalt waste materials, etc.) by such means as adopting shallow pipe installation method and the method of replacing pipes without excavation of construction.

Appropriate use and discharge of water resources

Water is not a primary material among the products the Daigas Group handles. We recognize that water does not pose a major business risk for our Group because we are operating in areas, both in Japan and abroad, where water risk is not high.

However, the Group controls water discharge after using drinking water, industrial-use water, ground water and seawater. At power plants, core facilities for its electricity business, the Group uses industrial water as a coolant in a steam turbine condenser, and vaporizes it inside the cooling tower. Drinking water, industrial-use water, ground water and seawater are also used at LNG terminals, power plants and offices, and discharged into the sea. Seawater, for example, is discharged into the sea after it is used mainly at LNG terminals for vaporization of LNG, not for consumption. At some power plants, seawater is also used as a coolant in a steam turbine condenser and discharged into the sea without being consumed. In discharging water after it is used for our industrial activities, we have controlled its quality, such as COD (chemical oxygen demand), pH, phosphorus and nitrogen, in line with relevant laws, ordinances and agreements with local municipalities. Thanks to such efforts, there were no violations regarding the quality of water being discharged. The Daigas Group sees water as a limited natural resource. We will continue to use water adequately, control its discharge strictly, and promote water saving.

As for the reduction of water intake (drinking water and industrial-use water), we are managing it in step with our efforts to reduce other activities that weigh on the environment, while using Environmental Management Indicators.
