  • *1For district heating and cooling centers that sell power using combined heat and power (CHP) systems (gas engine-based CHP systems generate electricity and recover exhaust heat generated as a by-product), data for energy used for power generation is reflected in “Power plants and data for energy used to produce heat is reflected in “District heating and cooling centers”. Data for “Tokyo Gas business offices, etc.” does not include energy used for LNG terminals and district heating and cooling centers. “Other Group companies” refers to data on Group companies excluding district heating and cooling centers, and power plants.
  • *2Some variance in the data listed under different categories may exist since the data has been processed to properly assess the changes in energy usage intensity for each business activity (such as by reflecting the amounts commissioned by other companies at LNG terminals).
  • *3The values are calculated based on the adjusted emission factors since fiscal 2018.
  • *4CH4 (methane) emissions were converted to CO2 emissions by multiplying by the global warming potential of 25, as stipulated in the Act on Promotion of Global Warming Countermeasures.
  • *5For the crude oil equivalent of electricity usage under “District heating and cooling centers” and “Tokyo Gas business offices, etc.,” the amounts purchased from power utility companies were all calculated using daytime electricity factors.

Assessment of CO2 Emissions Reduction due to Reductions in Purchased Electricity

Amount of Thermal Power Generation Varies According to Electricity Usage
In Japan, the electricity supplied by electric utilities is generated primarily by thermal power, nuclear power and hydroelectric power plants. Nuclear power plants operate at full capacity except when undergoing a routine inspection, while the annual power output of hydroelectric power plants is determined by the amount of rainfall. The electricity supply is adjusted by operations at thermal power plants. Therefore, in terms of total annual output, it is most likely to be thermal power generation that is cut when electricity use is reduced through energy-saving measures.
 

Lower electricity usage results in lower thermal power output
