Environmental Protection Guidelines (FY2015 Numerical Targets and Results)

Tokyo Gas Group has established and is working to achieve guideline targets in six fields in order to contribute to the realization of a low carbon society, the creation of a resource-saving society, and the development of a society that coexists with nature in line with its Environmental Policies. In fiscal 2015, we reported on our targets and performance in accordance with the Environmental Protection Guidelines (2014-2020) revised in fiscal 2014 (fiscal 2012 in the case of the Guidelines for Global Warming Countermeasures). In fiscal 2016, the guidelines were partially revised, with, for example, the Guidelines for Global Warming Countermeasures which cover our electric power business being revised to take into account our entry into the electricity retail market. Regarding the revised Environmental Protection Guidelines (2016-2020), please see the pdf file below.

Promotion of biodiversity conservation Our Group companies are aware of the importance of the benefits born from biodiversity (ecosystem service). As such, we work to understand and analyze the impacts our business activities have on biodiversity, and work to improve our business operations, promoting activities for biodiversity conservation. Moreover, as part of our social programs, we are also involved in issues concerning biodiversity, even in areas that are not related to our own business activities. - - -

Notes:

  • ✽1Reduction of CO2 emissions through "Global warming countermeasures at customers' sites" has been calculated in the categories of cogeneration (including ENE-FARM) installation, enhanced efficiency of gas equipment, fuel switching, and diffusion of power generation from natural gas power plants. Reduction effects of cogeneration and the increase of power generation from natural gas power plants were calculated with a marginal emission factor (0.69kg-CO2/kWh, 0.65kg-CO2/kWh).
  • ✽2The average CO2 emissions factor for transmitted power of all wholesale electricity, including not only business-use power purchased from power plants of our Group, but also that of other companies and markets.
  • ✽3"Production plants" refer to sites that produce city gas and other products, district heating and cooling centers, and power plants.
  • ✽4"Zero emission" is defined as a "final disposal rate of less than 0.1%," where the final disposal rate is obtained by dividing the amount of waste disposed of by landfill per year by the total emissions of industrial waste by production plants per year. However, asbestos and other non-recyclable industrial waste are excluded from the figure for total emissions of industrial waste by production plants.
  • ✽5Sites refer to our business locations except for production plants and construction work sites. Construction work on main and branch supply pipelines, for which orders are placed by Tokyo Gas and received by its subsidiaries and affiliates, produces a large amount of industrial waste, most of which is recycled. This has therefore been excluded from this category.
  • ✽6Amount of copy paper sheets is calculated based on A4-sized paper.
  • ✽7Ratio of actual surplus soil disposed of against baseline when compared to that from conventional construction methods.
  • ✽8Subject items consist of all items purchased through electronic catalogs, including office supplies, office furniture, office fixtures, business cards, envelopes, and printed materials (but excluding tools, safety items, laboratory instruments, etc.). Calculation was made based on the purchase amount.

Framework for Establishing the Guidelines Index

The framework for establishing quantitative indices for the Environmental Protection Guidelines is explained in the following section.

Guidelines for Global Warming Countermeasures
  • In our city gas business, the amount of CO2 emissions at customers' sites far exceeds that from our business operations. Thus, reducing the amount of CO2 emissions at customers' sites is the utmost importance, and our targets have been established accordingly.
  • Regarding the CO2 emissions from our own business operation, our primary goal is to reduce the energy usage intensity of city gas production at our LNG terminals, which have the highest energy usage. We also reduce absolute emissions from energy usage at our offices, etc. Targets have also been set for reducing CO2 emission factors and the heat sales intensity of power generation and heating and cooling business.
Guidelines for Promotion of Resource Saving
  • The gas industry is involved in three waste management fields: industrial waste, general waste, and excavated soil.
  • In particular, industrial waste is managed by: efforts to achieve zero emissions targets at production plants of Tokyo Gas Group, and by promoting the 3Rs (Reduce, Reuse, Recycle); and efforts to enhance recycling rate of industrial waste generated from locations other than those production plants.
  • Under the Guidelines revised in fiscal 2014, we are stepping up such efforts by further dividing industrial waste from locations other than production plants into that from construction sites and that from offices and other locations.
  • When conducting construction work of gas pipeline, roads and other surfaces must be drilled, which results in the generation of excavated soil (soil, asphalt concrete, etc.). Thus, we are involved in efforts to reduce, reuse, and recycle in order to reduce the amount of excavated soil generated.
Guidelines for Promoting Green Purchasing
  • We strive to reduce our overall environmental burden not only by working to improve our own operations to use less energy and produce less waste, but also by helping to reduce the environmental burden in upstream activities through the promotion of green purchasing. Among our efforts, we are indexing and controlling the green purchasing rate targeting overall purchases from electronic catalogs (however, this excludes difficult to acquire eco-friendly items such as tools, safety items, and physics and chemistry equipment).
