1. Installation of the Sus-Katsu Program app will automatically visualize CO2 reductions in the home

Of the Mitsui Fudosan Group’s greenhouse gas emissions, 88% are emissions outside the organization (Scope 3). A high percentage of those external emissions are CO2 emissions generated when people move into properties and so forth, and measures to help reduce CO2 emissions after moving in are also important. On the other hand, not knowing exactly what to do to help and a lack of motivation to participate in decarbonization activities are issues from the consumer’s point of view.

Using the app developed by Familynet Japan automatically visualizes the amount of CO2 used and reduced by linking such data as the amount of electricity and gas provided to each household by Familynet and Tokyo Gas, respectively.

2. Points are automatically awarded in the app depending on CO2 reductions, and these can be exchanged for various types of rewards

Using the app automatically awards points based on the amount of CO2 reduced, and accumulated points can be exchanged for various rewards, or the opportunity to receive them.

Every household resident can use the app, providing opportunities to accumulate points through participating in related events in addition to day-to-day CO2 reductions. Using this app will provide various types of support to sustainably and effectively reduce CO2. App screenshot

  • 1　Based on Mitsui Fudosan Residential’s research.
  • 2　The Sustainable Living Program (“Sus-Katsu Program”) serves as an initiative for bolstering CO2 reduction efforts as part of people’s daily lives by urging people to take part in such efforts and making appealing rewards and other such incentives available to program participants. According to Japan’s Ministry of the Environment, the residential sector accounted for approximately 15% of the nation’s CO2 emissions during fiscal 2021, which highlights the importance of reducing CO2 emissions from households when it comes to achieving a low-carbon society. Meanwhile, from the perspective of residents, there are challenges such as not knowing specifically what they should do. With this situation in mind, Mitsui Fudosan Residential is engaging in the Sus-Katsu Program in hopes of helping to reduce CO2 emissions in the residential sector by establishing a framework for bolstering CO2 reduction initiatives enlisting efforts of Sus-Katsu Program partners, and by underpinning carbon neutrality initiatives that are personalized as well as enjoyable and capable of being sustained on an ongoing basis by offering participants special experiences and products through affiliated partners who have endorsed the program.

■Sustainability in the Mitsui Fudosan Group

Based on the meaning of its “& mark,” “to generate new value with society through cooperation, coexistence and co-creation, we forge ahead, innovating,” the Mitsui Fudosan Group views the “creation of social value” and the “creation of economic value” as two wheels of a cart. Accordingly, we believe that the creation of social value leads to the creation of economic value, and that this economic value then creates even greater social value.
Moreover, we identified six Group Materiality priority issues when formulating our new management philosophy in April 2024. These Group Materiality priority issues are (1) Contribute to industrial competitiveness, (2) Coexist with the environment, (3) Health and Vitality, (4) Safety and security, (5) Diversity and inclusion, and (6) Compliance and governance. The Mitsui Fudosan Group will work to address each of the materialities through its core business activities and contribute to the promotion of sustainability.
