Environmental Data IndicatorUnitCalculation Method 
Energy Energy consumption  Thousand kl of crude oil 

{(Amount of electricity purchased × Per-unit heating value + Amount of heat purchased × Per-unit heating value) + Σ (Amount of each fuel used × Per-unit heating value for each fuel)} × 0.0258 The per-unit heating value of electricity, per-unit heating value for each fuel, and the types of fuel included in the scope of calculation are based on the values and calculation methods outlined in the Act on the Rational Use of Energy.

Because we calculated GHG emissions in accordance with the GHG Protocol from fiscal 2017, the energy usage amount includes the energy used to produce electricity and steam sold to external parties by the Group. The heating value used overseas is based on standard heating values used in the formulation of Japanese laws.

Atmospheric Emissions  Greenhouse gas emissions  Thousand tons of CO2

CO2 emissions from energy use:
Amount of electricity purchased × CO2 emission factors for electricity + Amount of steam purchased × CO2 emission factors for steam + Σ(Amount of each fuel used × Per-unit heating value for each fuel × CO2 emission coefficient for each fuel)

The CO2 emission factors for steam, per-unit heating value for each fuel, and CO2 emission factors for each fuel are based on the values outlined in the Greenhouse Gas Emissions Accounting, Reporting, and Disclosure System of the Act on Promotion of Global Warming Countermeasures. The CO2 emission factors for electricity in Japan uses the values for each fiscal year by electric power company and that for overseas uses the values by electric power company along with the IEA’s fiscal 2016 efficiency indicators for each country. From fiscal 2017, results include the energy used to produce the power and steam sold to external parties in accordance with the GHG Protocol.

CO2 emissions from other than energy use and non-CO2 GHG emissions:
In Japan, results are based on the calculation method outlined in the Greenhouse Gas Emissions Accounting, Reporting, and Disclosure System of the Act on Promotion of Global Warming Countermeasures. From
fiscal 2017, results include CO2 emissions generated by processes not subject to reporting under the Act on Promotion of Global Warming Countermeasures but that emit 3,000 or more tons of CO2 per year. Overseas, figures are calculated in accordance with the laws and regulations of their respective countries.
