Calculation Scope ORIX Group Companies in Japan and overseas (including affiliated companies)
Basic Concept
  • Calculations are performed by multiplying the reduced amount of activity among customers or society as a whole due to ORIX Group’s renewable energy business activities by CO2 emissions factors.
  • Operating Margin Grid Emission Factors by country and region from “The IFI Dataset of Default Grid Factors v3.2” are used for emissions factors.
  • We calculated CO2 avoided emissions based on our ownership ratio.
Other For biomass power generation data in the United States, the biogas capacity (unit: BTU) was converted to kWh.

Scope and concept of calculation for past years
Calculation Period From April 1 to March 31 each fiscal year
Calculation Scope ORIX Group Companies in Japan and overseas (including affiliated companies)
Basic Concept
  • Calculations are performed by multiplying the reduced amount of activity among customers or society as a whole due to ORIX Group’s business activities by CO2 emissions factors.
  • For calculation of business activities in Japan, in principle the emissions factors we use are “alternate values” under the Greenhouse Gas Emissions Accounting, Reporting, and Disclosure System (Act on Promotion of Global Warming Countermeasures).

    Emissions Factors
    FY2018.3  0.000512 t-CO2/kWh
    FY2019.3  0.000500 t-CO2/kWh
    FY2020.3  0.000488 t-CO2/kWh
    FY2021.3  0.000470 t-CO2/kWh

  • For calculation of overseas business activities, in principle, we use emissions factors from each country.
  • Calculations also include CO2 reduction credits redeemed during the calculation period after being acquired by ORIX Group.
  • We calculated CO2 avoided emissions based on our ownership ratio.

Calculation Boundary and Method
Calculation Period From April 1 to March 31 each fiscal year
Calculation Boundary FY ended March 2020: Consolidated ORIX Group companies in Japan (excluding investees in our PE Investment business)
FY ended March 2021 and FY ended March 2022: Consolidated ORIX Group companies (Japan and overseas, excluding a limited number of overseas offices)
FY ended March 2023: Consolidated ORIX Group companies (Japan and overseas, excluding a limited number of overseas offices as well as entities which were consolidated in the last quarter of the fiscal year)
FY ended March 2024: Consolidated ORIX Group companies (Japan and overseas, excluding entities which were consolidated in the last quarter of the fiscal year)
Target Activities GHG Protocol direct emissions (Scope 1) and indirect emissions (Scope 2)
Calculation Method
  • GHG emissions (converted to CO2) are calculated based on the GHG Protocol and Japan’s “Ministerial Ordinance Concerning Calculation of Greenhouse Gas Emissions Associated with Business Activities of Specified Emitters” (calculated based on ORIX Group’s GHG calculation guidelines).
  • GHG emissions, including CO2 from non-energy sources, methane (CH4), and dinitrogen monoxide (N2O), are calculated based on ORIX Group rules concerning the management of environmental information.
  • Includes emissions from some domestic rental assets over which we have energy management authority under Japan's Act on Rationalizing Energy Use and Shift to Non-fossil Energy.
  • In principle, we use the emissions factors under Japan's Mandatory Greenhouse Gas Accounting and Reporting System before the 2024 amendment.
  • Scope 2 emissions are market-based emissions, and post-adjustment emissions factors are used as emissions factors related to electricity consumption at offices in Japan. For the fiscal year ended March 2024, the adjusted emission factors published by the Ministry of the Environment in December 2023 for each electricity provider are used. For emissions factors related to electricity consumption at overseas offices, electricity provider-specific emission factors are used when available, and otherwise the International Energy Agency’s CO2 emissions factors from electricity generation by country are used.
  • Scope 2 emissions include emissions related to power purchases from ORIX Group power generation companies (intra-Group transactions). Emissions related to power purchases (intra-Group transactions) for the fiscal year ended March 2024 were 6 thousand t-CO2e.
  • Some calculations use estimated values.

[Notes]

・ Change in emissions factors: Beginning from the data for the fiscal year ended March 2022, we have changed the calculation for emissions related to electricity consumption to the market-based method.
・ Emissions from coal-biomass co-fired power plants: ORIX operates two coal-biomass co-fired power plants in Japan. One is Soma Coal and Biomass Power Plant in Soma City, Fukushima Prefecture, which started operations in March 2018. The other is Hibikinada Coal and Biomass Power Plant in Kitakyushu City, Fukuoka Prefecture, which started operations in December 2018. Each of these power plants has a total generating capacity of 112MW. Emissions from these two plants for the fiscal year ended March 2024 were 796 thousand t-CO2e.

ORIX Corporation Water Usage and Waste Disposal Volume

Water Usage
  FY ended March 31, 2022 FY ended March 31, 2023 FY ended March 31, 2024
Water withdrawal Approx. 249,000m3 Approx. 273,000m3 Approx. 282,000m3
Rainwater Approx. 2,000m3 Approx. 2,000m3 Approx. 2,000m3
Water discharge Approx. 248,000m3 Approx. 272,000m3 Approx. 280,000m3
Scope and Method
Calculation Period From April 1 to March 31 each fiscal year
Calculation Scope ORIX Corporation
Calculation Method
  • Most of the water withdrawal is purchased from utilities. However, rainwater use is reflected in the water withdrawal figure because some buildings where ORIX Corporation is a tenant collect and use rainwater. No other sources such as surface water or groundwater are used for water withdrawal.
  • Wastewater is discharged into the sewage system at all locations, and the amount is essentially the same as the amount of water withdrawal.
  • For locations where actual water usage could not be ascertained, it was estimated using a basic unit average calculated by a green building industry association based on water usage and floor space of locations. In this calculation, the water intake and wastewater amounts are assumed to be the same.

[Notes]

・ The scope of data calculation for water usage encompasses, in principle, locations for which disclosure is required under the Act on the Rational Use of Energy. All locations owned and managed by ORIX Corporation are covered. 100 locations used water in the fiscal year ended March 2024.

Waste Disposal Volume
  FY ended March 31, 2022 FY ended March 31, 2023 FY ended March 31, 2024
Disposal volume 661 tons 302 tons 353 tons
Scope and Method
Calculation Period From April 1 to March 31 each fiscal year
Calculation Scope ORIX Corporation's industrial waste*1

*1 The waste subject to calculation is the industrial waste generated from business activities as defined in the Japanese law “The Waste Management and Public Cleaning Act”, such as cinder, sludge, waste oil, waste acid, waste alkali, waste plastics and other specified waste.
Calculation Method
  • Emissions are calculated using the industrial waste manifests*2 issued by ORIX Corporation.

*2 A document describing the type and quantity of industrial waste that, under the Waste Management and Public Cleaning Act, must be issued by a business that generates industrial waste and entrusts the disposal of such waste to another company.

[Notes]

・ ORIX Corporation moved its headquarters in May 2021. Therefore, the amount of waste temporarily increased for the fiscal year ended March 31, 2022.
