Environmental Management

Continual Improvement of Environmental Management System

In order to promote environmental protection activities in line with our Management Philosophy, Corporate Action Philosophy, Our Code of Conduct, and Environmental Policies, Tokyo Gas has developed and is operating an environmental management system (EMS) that complies with the ISO 14001:2004 international standard. We ensure that resource and energy conservation and various other activities to protect the environment are practiced properly and systematically by applying solid PDCA principles. These initiatives offer the additional benefit of reducing costs. We have now commenced operation of an ISO 14001:2015-compliant EMS, and our transition is scheduled to be audited in September 2017. Operation of a new EMS that embraces both our core business and environmental activities will further raise employees’ environmental awareness and ensure legal compliance.

Efforts of the Group

Tokyo Gas Group has introduced EMS, including certification to ISO14001 and Eco-Action 21 standards, at consolidated subsidiaries and affiliates and other group companies that have a major impact on the environment in order to enhance environmental management throughout the Group. Today 95% of the Group (in terms of sales) practices environmental management in accordance with ISO 14001 standards. Looking ahead, we will explore new arrangements for implementing EMS that are suited to individual companies' scales and lines of business as we construct our new group formation, and the Group will work as one in pursuing steps to improve the environment.

Measures Taken against Environmental Risks

Measures Taken against Environmental Risks
Tokyo Gas believes that being actively involved in both regional and global environmental issues is an important aspect of our corporate management, and we conduct our business activities accordingly. We identify the latent environmental risks present in our business activities, and we practice proper management to mitigate them and prevent them from having a serious impact on the environment. We also voluntarily research and publish information on the environmental impacts and pollution caused by our operations in the past, and we believe that we must take swift action to address any concerns that arise in order to protect the environment. 
When serious environmental risks manifest themselves, we take swift emergency action and measures to prevent a recurrence according to their risk level in accordance with our Emergency Response Organization Regulations, and we also standardize management flows to ensure that secondary risks do not arise.


State of compliance with environmental regulations and fines
Tokyo Gas Group was not cited for any violations nor fines with respect to environmental laws and regulations in fiscal 2017.

Measures Taken for Soil Remediation

Since fiscal 1999, we have been conducting soil tests and groundwater surveys on all land currently or formerly owned by Tokyo Gas on which soil contamination may have occurred, such as the sites of old plants. When the presence of contaminants has been confirmed, we have proactively released the relevant information by a variety of methods, including by reporting the issue to the relevant authorities, explaining the situation to local residents, and issuing press releases, and taken appropriate action to deal with the contamination.
According to the circumstances, contamination is dealt with in practice by preventing the dispersal of contaminated soil by, for example, excavating and removing it or surfacing roads, and by preventing the dispersal of groundwater by, for example, pumping up groundwater and installing impermeable walls. Presently too when we carry out excavation work, we file notifications and conduct surveys as required by the Soil Contamination Countermeasures Act and associated ordinances, and we continue to practice environmental management by taking steps to prevent the dispersal of contaminated soil and disposing of excavated soil properly.
Prompted by the act’s revision in 2010, we now also treat naturally occurring contamination and contamination thought to have been caused by landfill activity the same as contamination caused by our activities, and deal with it appropriately in accordance with the law.

Management of Chemical Substances

Although only small quantities of hazardous chemicals are used in the process of producing and supplying gas, the Group will continue to manage chemical substances in accordance with applicable laws and regulations and take action to reduce emissions.
 

Response to the PRTR Act

In fiscal 2016, the Group handled or otherwise dealt with the following amounts of substances subject to reporting under the PRTR Act. In fiscal 2016, no subsidiaries were required to file reports under this act.


Tokyo Gas
(Unit: kg)
Substance Amount handled Release Transfer Remarks
Xylene 4,090 0.1 0.0 Refueling
1,2,4-Trimethylbenzene 2,015 0.0 0.0 Refueling
Toluene 8,800 0.9 0.0 Refueling
N-hexane 3,445 2.2 0.0 Refueling
 

Measures for fluorocarbons

Tokyo Gas identified and inspected specified products (commercial air conditioners, refrigerators, and freezers) for which it is responsible as manager under the Act on Rational Use and Proper Management of Fluorocarbons, which came into force in April 2015. In fiscal 2016, estimated leakages at Tokyo Gas and one subsidiary exceeded 1,000 t-CO2, and so a report was submitted to the minister with jurisdiction for the operations in question. As a registered fluorocarbons filling/recovery operator, Tokyo Gas also collected and appropriately disposed of fluorocarbons removed during inspections and maintenance of GHP products.
The electric chillers introduced in the past few years use low GWP (greenhouse warming potential) fluorocarbons. Low-GWP chillers will continue to be adopted.

VOC measures

Since 1991, Tokyo Gas has been working on reducing VOCs (volatile organic compounds) emission when painting items such as gas holders. Recent efforts include the transition to a painting method that uses weak solvent-based paints (low VOC paint method). We will continue to work on further VOCs emission reduction.

Hazardous waste management

Hazardous waste held by Tokyo Gas that contains PCBs is centrally stored at the Negishi LNG Terminal and other sites, and managed appropriately in accordance with the Act on Special Measures concerning Promotion of Proper Treatment of PCB Wastes. Items such as high-level PCB-contaminated high voltage transformers and capacitors and low-level PCB-contaminated waste are processed properly in line with administrative processing schedules and policies. The state of disposal in fiscal 2016 is as shown in the table below. High-level PCB-contaminated capacitors and stabilizers of less than 3 kg were pre-registered with JESCO in the second half of fiscal 2016 and are to be appropriately disposed of in fiscal 2018.
 

Disposal of PCB Waste in FY2016
Type of waste Disposal amount
Large low-level PCB-contaminated transformers 4 units
Transformers for DC withstand voltage testing 1 unit

Action on Climate Change

The Group recognizes concerns that climate change may affect our business activities as follows, and is taking appropriate action in response.



Global warming countermeasures (mitigation)

In order to reduce emissions of greenhouse gases, which are considered to be a cause of temperature rise, the Group has formulated Guidelines for Global Warming Countermeasures and will act to reduce emissions from our main sources of emissions, namely city gas production facilities, district heating and cooling centers, power plants, and offices, as well as work to reduce emissions at customers' sites.

Natural disaster countermeasures (adaptation)

Among the possible effects of climate change (heavy localized downpours, storm surges, etc.) are damage to city gas facilities and delays to or interruption of LNG supplies in transit. Tokyo Gas is therefore hardening its production and supply facilities against disasters, and is making active use of private-sector weather forecasts to help prepare for and prevent wind and flood damage. In addition, we believe that diversifying the sources of the LNG we use to make city gas will help limit disruption to supply chains in the event that a source is struck by a natural disaster.

 

Response to stricter legal regulation to combat climate change

Regulations in areas such as carbon emission trading and carbon taxes may impose constraints on the use of fossil fuels. However, by stepping up efforts to encourage fossil fuel users to switch from oil and coal to cleaner natural gas, promote wider adoption of highly energy efficient equipment and systems such as cogeneration systems, encourage renewable energy use, and develop smart energy networks, we are committed to contributing to the realization of a low carbon society.

Action to Address Water Risks

Third-party assured
The Group recognizes threats to water resources as a business risk and therefore manages the amount of tap water, industrial water, and seawater it uses in order to conserve freshwater and control wastewater emissions. In fiscal 2016, we used a total of 5,017 thousand m3 of freshwater at the LNG terminals where city gas is produced, district heating and cooling centers (DHCs), power plants using LNG, offices, and other facilities in Japan. We are working to reduce process water consumption at LNG terminals, DHCs, and power plants by optimizing boiler operation, reducing steam loss, replacing chillers with more efficient electric turbo types, and more. To reduce our use of tap water at offices and similar facilities, we are making greater use of wastewater, installing water-saving toilets, and encouraging employees to conserve water. Regarding wastewater, we measure emissions and manage indicators of water quality, including pH, COD*, and nitrogen and phosphorus concentrations, in accordance with local government ordinances, agreements, and other relevant standards. Seawater is used mainly at LNG terminals and power stations as a heat source, and is returned in its entirety to the sea. Looking overseas, although we are not presently doing business in any regions subject to high water risk, we will monitor the business risks associated with water use wherever we establish operations and respond appropriately as we accelerate our globalization in the years ahead.
In fiscal 2016, water risk assessments were conducted at two locations—a city gas production plant in Japan and a business unit in Thailand—and these found that risks in these regions are not especially high.
