Environmental Measures


In accordance with Sustainability Policy, MIRAI has set the following sustainability targets in order to appropriately identify and manage the environmental impact of real estate management and to conduct management that contributes to environmental conservation.

Main Targets
■Reduce GHG emission intensity of our portfolio by 5% over the next 5 years
■Reduce energy consumption intensity of our portfolio by 5% over the next 5 years

  • The target period is from April 2021 to March 2022 as the first year, and from April 2025 to March 2026 as the year to achieve the target.
    In addition, from April 2018 to March 2019 is the base year.

  • Actual figures are rounded down to the first decimal place, and percentages are rounded to the first decimal place.
  • The performance data covers properties held as of the end of March each year. Properties that were sold or acquired during the period and for which data is difficult to obtain are excluded from the calculations.
  • The emission factors used in the calculations are based on the "List of Calculation Methods and Emission Factors under the Calculation, Reporting and Publication System" (https://ghg-santeikohyo.env.go.jp/calc) published by the Ministry of the Environment.
  • Intensity=Total consumption / (gross floor * Occupancy rate(annual average))
  • “Energy” excludes consumption of renewable energy.
  • Some data for the period ending March 31, 2022 have received a limited assurance by a third-party organization.
  • As a result of a close examination in conjunction with the granting of third-party assurance to environmental data, some of the previously published data has been revised.

Environmental survey at the time of property acquisition

Environmental surveys are conducted as a due diligence item at the time of property acquisition, confirming the presence or absence of hazardous substances such as asbestos and PCB, and soil contamination based on expert reports.

Green lease contract

MIRAI has entered into green lease contracts with some of its tenants that provide for environmental considerations.

Acquisition of environmental certification

MIRAI promotes the acquisition of environmental certification for its properties. Please refer to here to see the status of certifications for each property.
