Note)

Scope 3-1: Calculated by multiplying the emission factor specified by the Ministry of the Environment by the services received during the target period. Scope 3-2: Calculated by multiplying the emission factor specified by the Ministry of the Environment by the increase in depreciation expenses. Scope 3-5: Calculated by multiplying the emission factor specified by the Ministry of the Environment (including the transportation stage) by the amount of waste generated (by type and treatment method). Types and treatment methods: Calculated using statistical data from the Ministry of the Environment or relevant industry associations. Scope 3-13: Emissions associated with tenant business activities. Scope 3-13 Data Coverage Rate: The ratio of tenant floor area disclosed to total leasable floor area. Scope 3 Impact Ratio: The proportion of Scope 3 emissions relative to total GHG emissions. Activity Unit Denominator: Total floor area (㎡) adjusted for operating months.

Note)

Estimated value: Estimated based on the Tokyo Metropolitan Government Bureau of Waterworks’ “Survey on Actual Conditions of Domestic Water Use,” using the average monthly water consumption per household by household size. Actual coverage rate (water withdrawal basis): Ratio of measured water withdrawal to total water withdrawal. Actual coverage rate (floor area basis): Ratio of floor area with measured data to the total floor area. Intensity denominator: Total floor area (㎡), adjusted for months of operation.

Green lease is an agreement specifying that property owners and tenants shall cooperate to reduce environmental burden.
Since 2021, Star Asia Investment Corporation (“SAR”) has promoted the incorporation of Green Lease provisions upon signing lease contracts with tenants.

Ratio of green lease (※) 54.3% (As of July 31, 2025)
※Ratio of area leased under green leases to total rentable area.

Efficient energy consumption and environmental preservation is being promoted mainly by the Sustainability Promotion Division, by examining the contents of construction works and specification of facilities, and renewing facilities etc. at appropriate timing and adequate specifications.
