Appropriate Utilization of Resources and Pollution Control

Approach and Policies

Group Policy (Environment)

Under the values set forth in the Group Policy, the Group regards the depletion of natural resources and the pollution caused by waste in urban development business activities as urgent social issues and is working in cooperation with relevant stakeholders to reduce its impact on the environment and improve the resource use efficiency through waste reduction, appropriate management of chemical substances, and sustainable resource use.

The Group has set the following two targets to promote appropriate utilization of resources and pollution control.

Target 1. Reduce Waste Discharge
Target 2. Promote the Use of Domestic/Certified Lumber

Result 2. Promote the Use of Domestic/Certified Lumber

To reduce the risk of disrupting the ecological balance and impact on local communities due to illegal logging, the Group established the Nomura Real Estate Group CSR Procurement Guidelines, which stipulate the sustainable use of resources and methods of use of wood materials.


Responses Regarding Substances of Environmental Concern

The Group takes appropriate action to prevent environmental impact and detrimental health effects caused by soil contamination and chemical substances.

Response to Soil Contamination/Water Pollution

When acquiring land, the Group investigates the history of land use of the site and, if soil contamination is suspected, hires specialists to conduct soil surveys. If soil contamination is detected, we take appropriate measures including removal and containment of the contaminated soil in accordance with the Soil Contamination Countermeasures Act and other relevant laws and regulations. Similarly, we take appropriate measures if a problem with water pollution is detected.

Proper Management and Reduced Usage of Chemicals

When developing residences, office buildings, commercial facilities, and so on, the Group uses construction materials with four-star ratings (highest rating) for formaldehyde emissions in accordance with its Design and Construction Standards and Quality Manuals. In addition, we require that construction companies submit quality control check sheets and measure the five substances designated as specified measurement substances under the Housing Quality Assurance Promotion Act (formaldehyde, toluene, xylene, ethylbenzene, and styrene) when construction is completed.

Appropriate Asbestos Measures and Ongoing Monitoring

The Group handles asbestos found during demolition work with the utmost caution and care by cordoning of affected areas and ensuring regular third-party testing of concentration and emissions. We also conduct continuous monitoring to ensure that no problems exist.

Reduction and Appropriate Management of Waste Discharge

The Group uses highly durable materials with long lifespans and implements appropriate management and repair plans to increase the lifespans of buildings. In addition, we aim to reduce waste discharge and increase the recycling rate throughout the life cycles of products and services.

Restoring Condominiums

The Group is working to restore old condominiums into homes with new value. We expanded PROUD Uehara Forest, which was established more than 30 years ago, by utilizing its excess floor space with the latest technologies while improving its livability. As a result, it was certified as excellent long-term housing for the first time as an old condominium built by a private developer. It was also certified as having a service life of 65 years by a third-party evaluation agency.

The NOHGA Hotel, operated by the Group, is working to reduce and reuse waste through such efforts as reducing the use of plastics by eliminating single-use toiletries and using biodegradable bamboo straws derived from plant fibers. It is also using name plates and handkerchiefs made from reused scraps of leather and Japanese clothing.

Use of Domestic Lumber

Nomura Real Estate Development is proactively deploying domestic/certified lumber as part of its efforts to conserve biodiversity and achieve sustainable use of resources. In our future construction projects, we plan to apply domestic lumber for the interiors of common areas in PROUD condominiums and introduce a wooden hybrid structure in our office building brand H¹O.
Domestic lumber not only allows us to provide a more comfortable living environment for our customers but also leads to the reduction of CO₂ emissions and prevention of natural disasters by preserving the recycling of forest resources.
