Continual Improvement to the Environmental Management System

Tokyo Gas has practiced effective and efficient environmental management under the leadership of top management since establishing its Group-wide environmental management system (EMS) in 2005 to comply with the ISO 14001. In fiscal 2017, we started operating an EMS that meets the revised ISO 14001:2015. By implementing PDCA cycles under the EMS we can ensure legal compliance and reduce environmental impact, preserve biodiversity and strengthen environmental partnerships, making our environmental protection activities both systematic and substantive.
To strengthen the Tokyo Gas Group’s environmental governance, we constructed the environmental management system, described below, and support the operation of environmental management systems at each Group company.

Environmental Risk Management

Mitigating Environmental Risks

All business offices of the Tokyo Gas Group operate environmental management systems under which they annually assess the environmental risks of all operations. We endeavor to improve high-risk operations by setting concrete targets and also conduct employee training, including study groups on relevant laws and regulations, to mitigate risks by raising environmental awareness. In the event that any violations of environmental laws occur, we seek to prevent any recurrence by sharing information and applying the learnings to similar operations across the Group.
For the crisis management system, we formulated the Emergency Response Regulations, with which the Emergency Response Organization will respond accordingly and immediately in the event of a crisis. In addition, we are strengthening the system by conducting periodic training and formulating a business continuity plan (BCP) to address major risks.

Climate Change Mitigation and Adaptation

The Group recognizes concerns that climate change may affect our business activities in the following ways and is responding appropriately.

Climate Change Countermeasures (Climate Change Mitigation)

To reduce greenhouse gas emissions, which are associated with rising global temperatures, the Group has drawn up the Guidelines for Global Warming Countermeasures. Also, it is working to reduce emissions from city gas production facilities, power plants, district heating and cooling centers and offices as well as from customer sites, which account for the largest share of CO2 emissions in the LNG value chain. Our efforts to combat climate change also include the development and dissemination of low-carbon systems.

 

 

Natural Disaster Response (Adaptation)

Climate change-induced disasters, such as localized torrential downpours and storm surges, may damage city gas production facilities and delay or halt LNG transport. We have formulated disaster preparedness plans at production, supply and other facilities as well as business continuity plans (BCPs) to prepare for a major accident, large-scale power outage or outbreak of disease caused by a major typhoon. In addition, we believe that diversifying the suppliers of LNG, which is used to produce city gas, will help minimize the risk of supply chain disruption when any single source is affected by a natural disaster.

Responding to Stricter Regulations to Fight Climate Change

The introduction of emissions trading systems and carbon taxes could lead to restrictions on the use of fossil fuels. We are committed to creating a low-carbon society by bolstering our efforts to encourage a fuel conversion from oil and coal to natural gas, the cleanest fossil fuel, expanding the use of highly energy-efficient appliances and systems such as combined heat and power (CHP) systems*1, promoting renewable energy use, and building smart energy networks.
  • *1Gas engine-based CHP systems generate electricity and recover exhaust heat generated as a by-product.

Managing Water Risk

Recognizing water risk as a key management concern, Tokyo Gas seeks to manage the risks by addressing issues such as water demand and supply, flooding, and public health.

Response to Water Risk

Water Demand
For the three years from fiscal 2016 through fiscal 2018, we combined the use of such international indicators as the WRI Aqueduct, WWF-DEG Water Risk Filter, and WWF-DEG Water Risk Filter (Map) to conduct comprehensive assessments and analyses on current risks, such as water demand, flooding, public health, and biodiversity as well as future risks, including the impact of climate change and securing water resources. The results showed that there currently are no major risks at any of the Group’s operational bases in Japan and abroad.
We also sought to confirm the presence of risks at our suppliers by conducting a questionnaire that includes efforts made by suppliers to reduce water use.
 
Flooding
To ensure stable energy supply, we have taken steps to protect LNG terminals and gas pipeline-related and other vital facilities from flooding associated with climate change, such as localized torrential downpours and storm surges, as part of our overall actions against natural disasters.
 
Public Health and Other Issues
We are striving to use water resources sustainably by monitoring the volume of water use and conservation as well as appropriately managing wastewater.
Status of Water Resource UseThird-party Assured
In fiscal 2018, we used a total of 4,952 thousand m3 of freshwater at LNG terminals where city gas is produced, district heating and cooling centers, power plants using LNG, offices and other facilities in Japan. We are working to reduce process water consumption at LNG terminals, district heating and cooling centers and power plants through such means as optimizing boiler operation, reducing steam loss and replacing chillers with more efficient electric turbo types. To reduce our use of tap water at offices and similar facilities, we are increasing our use of recycled water, installing water-saving toilets and encouraging employees to conserve water. Regarding waste water, we measure discharges and manage water quality through the use of indicators, such as pH, COD*1, and nitrogen and phosphorus concentrations, in accordance with national laws and regulations, local government ordinances, agreements and other rules. We use seawater mainly at LNG terminals and power stations as a heat source and then return the entire amount to the sea.

Combating Soil Pollution

Since fiscal 1999, we have been conducting soil tests and groundwater surveys on land currently or previously owned by Tokyo Gas, such as former plant sites, with potential soil pollution and taking the necessary measures when pollution has been confirmed. We proactively disclosed information through reports to relevant authorities, explanations to nearby residents and press releases.
Depending on specific circumstances, we have paved over or excavated and removed contaminated soil to prevent its dispersal. Also, we have installed impermeable walls or pumped out contaminated underground water to refrain it from spreading.
We continue to control soil pollution, reporting excavation work to authorities and conducting surveys in accordance with the Soil Contamination Countermeasures Act and relevant ordinances. Furthermore, we ensure that contaminated dirt is not dispersed and that excavated soil is handled properly.
With the revision of the act in April 2010, we have taken action to address soil pollution caused by natural factors or landfill with the same commitment as legally mandated interventions for pollution associated with our business operations.
