CSR at the Tokyo Gas Group
The Tokyo Gas Group's LNG Value Chain and Its Impact on Society

In order to ensure the safe, uninterrupted supply of energy to our customers in and around Tokyo metropolitan area, the Tokyo Gas Group engages in a chain of business activities, extending all the way from natural gas procurement and transportation to the production and supply of city gas, power generation, and provision of energy solutions. We are committed to contributing to the sustainable development of society by enhancing the LNG value chain while continuing to develop technologies and leverage IT to meet future needs.

Main Activities and Main CSR Considerations

Procurement of Raw Materials
Darwin LNG Project
Darwin LNG Project
Long-term contracts entered
5 countries /12 projects
LNG procurement volume
13.875 million tons
Main Activities

In order to source natural gas flexibly and competitively to meet demand, we work with diverse players in Japan and abroad while diversifying our procurement sources, contract conditions, LNG networks, and other factors.

Main CSR Considerations
  • Raw materials procurement to ensure stable and affordable supply
  • GHG emissions from LNG suppliers’ gas fields and liquefaction facilities
  • Impact on biodiversity around LNG sources
Transportation of Raw Materials
Energy Horizon
Energy Horizon
LNG carriers owned and operated by Tokyo Gas
10 vessels
Main Activities

Tokyo Gas owns and operates its own fleet of LNG carriers, allowing raw materials to be shipped swiftly and flexibly. Four highly fuel-efficient, environmentally friendly carriers are now being built to further expand our fleet capacity in order to transport LNG sourced from the U.S. Cove Point Project, which comes on stream in 2017.

Main CSR Considerations
  • GHG emissions from transportation by LNG carriers
  • Impact on biodiversity of ballast water discharged from LNG carriers
Production of City Gas
LNG terminal storage capacity
384.5万kl
Sodegaura LNG Terminal

Hitachi LNG Terminal
Hitachi LNG Terminal
Main Activities

By receiving LNG and constantly producing city gas, the Group contributes to energy security in the Tokyo metropolitan area. Our 4 LNG terminals (Negishi, Sodegaura, Ohgishima, and Hitachi) function as mutual backups for one another, ensuring uninterrupted city gas supplies even in the event of a power failure or other incident.

Main CSR Considerations
  • Augmentation and development of LNG terminal storage capacity to ensure stable supply
  • Production problems due to natural disasters, etc.
  • GHG emissions from LNG terminals, resource saving and impact on biodiversity at LNG terminals
Power Generation
Power generation capacity (own stake)
Approx. 1,600MW
Main Activities

Using our LNG procurement capabilities and facilities such as our LNG terminals and pipelines, we operate high-efficiency combined cycle natural gas-fired power stations. We also generate electricity using wind power and other renewable energy resources.

Main Activities

The Group operates pipelines measuring a total of about 62,000 km in length. This network is being further developed to ensure the safe and stable supply of city gas. The Group is also involved in supplying gas over a wide area by supplying other gas utilities on a wholesale basis and transporting supplies by LNG tanker truck, ocean-going tanker, and coastal tanker.

Main CSR Considerations
  • Development of pipeline network and safety measures to ensure stable supply
  • Supply problems due to natural disasters, etc.
  • Soil excavated during gas pipeline construction and resource saving

Main Activities

The Group develops solutions combining multiple resources and technologies to reduce energy consumption and CO2 emissions and lower peak load. These include distributed energy systems (fuel cells and gas cogeneration systems), wider use of environmentally friendly gas appliances, and renewable energy sources. We are also providing energy systems that offer an optimal combination of gas, electricity, and added value.

Main CSR Considerations
  • Ensuring safety at customer sites
  • GHG emissions and resource saving at customer sites
  • Contributing to solving challenges in local communities
  • Protecting customers’ personal information
  • Ensuring quality and customer satisfaction

Overseas Upstream and Midstream/Downstream Operations
Main Activities

In addition to sourcing gas from existing large-scale LNG projects and acquiring participating interests, we are diversifying and expanding our sources and upstream projects overseas through involvement in unconventional gas (shale gas, etc.) and small-and medium-scale LNG projects. At the same time, we are leveraging the Group’s technologies and expertise in the total energy business to develop energy infrastructure and energy solutions for customers who are expanding overseas (especially in Southeast Asia and North America). By developing LNG value chains overseas as well as in Japan, we seek to contribute to both the flexible procurement of raw materials for Japan and the stable supplies of energy in the countries of these regions.

Main CSR Considerations
  • Raw materials procurement to ensure stable and affordable supply
  • GHG emissions from operations and impact on biodiversity
  • Contributing to solving challenges in local communities
