Key CSR Activities and Material Aspects: Targets and Performance - Contribution to the Environment
Global Warming Countermeasures

<Reasons for identification of material aspects>

To fulfill our duty as an energy company to minimize the impact on global warming.

Performance in FY2015: Overview and Assessment

Criteria for evaluating indicators Target achieved (100% or above)
Target not achieved but improved from previous fiscal year (not 100% achieved but improved from previous fiscal year)
× Target not achieved
Qualitative indicators with no evaluation axis are evaluated on the basis of whether or not progress has been made since the previous fiscal year.

FY2015 results Evaluation
<Customers' sites>
Reduction of CO2 emissions at customers' sites: 3.4 million tons

We aim to reduce CO2 emissions at customers' sites by 8 million tons by FY2020. This will be achieved through efforts implemented by the Group since FY2011 to promote the use of natural gas and to develop and disseminate gas appliances and systems that have higher efficiency and lower environmental load.

CO2 emissions reduced to 3.43 million tons at customers' sitesThird-party assured

CO2 emissions resulting from customers' use of gas were held to 3.43 million tons thanks to the promotion of natural gas use and the development and dissemination of gas appliances and systems that have higher efficiency and lower environmental load, including Eco-JOES and CGS. Increased use of gas to generate electricity due to the spread of natural gas power generation made an especially significant contribution to reduced CO2 emissions, allowing us to achieve our target.

<Electric power business>
CO2 emission factor in the electric power business: 0.36 kg-CO2/kWh

We aim to source more electricity from high-efficiency thermal and renewable energy power plants, and work to reduce the emission factor at the retail stage (revised FY2016).

CO2 emission factor in the electric
power business:
0.357 kg-CO2/kWhThird-party assured

Reduced the emission factor and attained our target by generating more electricity at high-efficiency power plants than last fiscal year.

<Business activities 1>
Energy usage intensity at LNG terminals: 220 GJ/million m3

We aim to achieve an energy usage intensity (consumption of primary energy per gas production unit) of 250 GJ/million m3 at our LNG terminals by FY2020.

Energy usage intensity at LNG terminals:
201 GJ/million m3Third-party assured

More energy-efficient operation of facilities and other strategies allowed us to meet our target despite an increase in energy usage intensity due to the raising of send-out pressure in response to growth in gas demand.

<Business activities 2>
Heat sales intensity at district heating and cooling centers: 1.33 GJ/GJ

We aim to achieve a heat sales intensity (consumption of primary energy per heat sales unit) of 1.19 GJ/GJ at district heating and cooling centers by FY2020.

Heat sales intensity at district heating and cooling centers:
1.34 GJ/GJThird-party assured

Despite plant efficiency improvements, failed to attain our target due to the approximately six-month shutdown of large-scale district heating and cooling centers for improvement work.

<Business activities 3>
Energy usage at Tokyo Gas offices, etc.: 915TJ

We aim to hold down energy usage (primary energy usage) at our offices, etc. to 910TJ in FY2020.

Energy usage at Tokyo Gas offices,
etc.: 887TJThird-party assured

Installed energy-efficient equipment and implemented energy conservation measures. We achieved our target, aided by the unusually cool summer and mild winter.

<Promotion of wider use of renewable energy>

We aim to contribute to the realization of a low carbon society through efforts to maximize the implementation of renewable energy. Such efforts include providing products and services that utilize renewable energy, supplying renewable energy (including power generation businesses), and promoting both networked use of energy and energy usage in certain aspects.

Active adoption of renewable energy

  • Continued to make maximum use of renewable and unused energy sources in various smart energy network projects.
  • 675,000 m3 of biogas derived from food waste was fed to city gas distribution pipes.
  • Examined the feasibility of the provisionally named Fukushima Coastal Wind Power Generation Initiative and submitted an environmental impact statement at the planning stage jointly with Fukushima Prefecture.
  • Numerical target for FY2015.

(CSR indicator)
Key initiatives
<Customers' sites>
We aim to reduce CO2 emissions at customers' sites by 8 million tons by FY2020. This will be achieved through efforts implemented by the Group since FY2011 to promote the use of natural gas and to develop and disseminate gas appliances and systems that have higher efficiency and lower environmental load.

Promotion of wider and more advanced use of natural gas

  • Expanding the use of distributed energy systems, including high-efficiency CGS and ENE-FARM, that contribute to lower peak load, save energy, and reduce CO2 emissions.
  • Fuel switching using advanced natural gas utilization technologies.
  • Promotion of high-efficiency natural gas-fired power generation.
  • Wide-area development of the natural gas infrastructure to provide a platform for the above measures.
  • Promotion of smart energy networks and support services for energy conservation, etc.
<Electric power business>
We aim to source more electricity from high-efficiency thermal and renewable energy power plants, and work to reduce the emission factor at the retail stage (revised FY2016).

Promotion of high-efficiency LNG thermal power

  • Commencement of operation of high-efficiency LNG power plants (capacity expanded by Kawasaki Natural Gas Power Station) and electricity purchases (Shinko Moka Power Station).
  • Steps to increase energy conservation during power generation and routine inspections.
<Business activities 1>
We aim to achieve an energy usage intensity (consumption of primary energy per gas production unit) of 250 GJ/million m3 at our LNG terminals by FY2020.

Promotion of more energy-efficient facilities and operation

  • Active promotion of more energy-efficient operation and equipment management to limit growth in energy usage intensity associated with the rise in send-out pressure to meet growing gas demand, enhancement of our facilities, and other factors.
  • More specifically, promote optimal operation according to the availability factor and forms of operation of production plants, appropriate equipment maintenance and systematic renewal of equipment to improve efficiency.
