Creating an environmentally friendly society

CO2 emissions (Scope 1, 2, 3)

We consider environmental impact monitoring to be essential for environmental conservation activities. Since fiscal 2017 we have been calculating CO2 emissions from electricity and gas use as well as CO2 emissions from driving gasoline vehicles. We also disclose CO2 emissions for Scope 3, given the importance of understanding the CO2 amounts emitted in upstream and downstream business activities in order to identify processes requiring environmental conservation efforts. With regard to the Company's business activities, CO2 emissions from electricity and gas use at rental housing are large, and therefore, providing energy-saving rental housing is an area in which the Company can make the most contribution to reducing our environmental impact. Monitoring has further revealed that the Company has also succeeded in lowering CO2 emissions in Scopes 1 and 2 (electricity and gas use and gasoline use) and Scope 3 in the fiscal 2018, continuing from the previous year.

Environmental Accounting

The Company makes active efforts to reduce its environmental impact through solar power generation. The right figures illustrate the results of applying our solar power generation to environmental accounting. CO2 emissions were reduced by 24,365t, equivalent to the amount of CO2 absorbed per year by about 2 million 40-year-old Japanese cedar trees based on the preliminary calculations of the Forestry Agency.

Contributing to a Low-Carbon Society by Building ZEH Housing

The Company's subsidiary Morizou Co., Ltd. offers "100-Year of Homes" made of kiso-hinoki, a premium precious wood. Morizou homes have industry-leading insulation and airtightness, and achieve high-energy efficiency by adopting designs that make the most use of the blessings of natural light and wind. Aiming to build a low-carbon recycling society to solve global warming issues, we will install energy creation facilities such as solar power systems with the goal of increasing the adoption of Zero Energy Home (ZEH*) to 50% by 2020. We will continue to develop eco-friendly homes to enable people to live economically and comfortably and to contribute to the creation of forests that protect the finite natural environment.

  • * Net zero energy house: House with zero net primary energy consumption per year

Participation in "Rokko Mountains Green Belt Development Project"

We have registered the Rokko Mountains Green Belt Development Project as a "Mori 'Forest' Guardian" and are engaged in activities twice a year. This project is handled by the Rokko Sediment Control Office of the Kinki District Development Bureau of the Ministry of Land, Infrastructure, Transport and Tourism. We are engaged in activities in line with the objectives of the maintenance business and one of our CSR-oriented activities, namely, the realization of an environmentally friendly society. We are working in cooperation with a number of departments to create a safe forest zone for Mt. Rokko and to realize SDGs15 code of "Life on land," meaning conserve and restore the use of terrestrial ecosystems.
