Basic Approach to Considering the Environment
The company declared in its “Environmental Charter” enacted in 1997 that it would make every effort to protect the global environment.
Further, with interest in the SDGs adopted in 2015 and in corporate ESG increasing, we revised our existing “Environmental Policy” in 2019 to “promoting environment-friendly management in order to realize a sustainable society that achieves a harmonious balance between the environment and the economy.”
And, in March 2021, with our newly enacted “VISION2030,” we raise the “environment” at the core of our corporate vision and will further strengthen efforts including reviewing our management system and enhancing information disclosure.
We introduced the environmental management system (ISO 14001) in 1999, and expanded it to a company-wide integrated management system in 2014.
We will work to prevent contamination as well as protect the environment and promote environment-friendly management in order to realize a "sustainable society" that achieves a harmonious balance between the environment and the economy.
1.Clarifying laws and regulations to be complied with as well as and promise to stakeholders
We clarify laws and regulations and promises to stakeholders that we should follow and comply therewith.
2.Identifying risks and opportunities
We identify risks and opportunities related to the situation surrounding the Company, the relationship between our business operations and the environment and laws and regulations and promises to stakeholders, and make efforts for reducing the risks while enhancing the opportunities.
3.Efforts as an environment-friendly company
- Promoting initiatives for saving the environment and reducing activities that impact the environment
- Preventing contamination of air, soil and water
- Restricting noise, vibration and dust generated
- Implementing biodiversity conservation
- Restricting greenhouse effect gases and construction by-products released
- Effectively utilizing resources and energy
- Developing, sophisticating and utilizing environmental technology
- Promoting designs that take global and local environments into consideration
- Contributing to local communities through the overall business operations
4.Enhancing the promotion structure for considering the environment
In order to meet increasingly sophisticated environmental needs in society, we enhance the promotion structure for considering the environment.
5.System operation and improvement
We establish, operate and continuously improve the environmental management system.
Considering the environment during the design phase is an important process in reducing the environmental impact in the building management phase.
We endeavor to incorporate environment-friendly design in all of our design projects, by promoting design that takes the global and local environment into consideration, as a priority initiative in our environmental policies.
With the aim of reducing CO2 emissions during building use, which account for 86.9% of CO2 emissions in the supply chain, we carried out ZEB* renovations on our Institute of Technology, which has stood for 25 years since its completion. As a result, we have currently achieved a 76% energy reduction, which is the highest level in Japan. We will continue to push forward with further improvements, aimed at a 100% energy reduction (Net Zero), in order to respond to a growing demand for renovation of existing buildings.
ZEB (Zero Energy Building: A building that reduces energy consumption to nearly zero)
- Energy-saving: External heat load reduction (double-skin curtain wall, exterior thermal insulation of exterior wall, multi-layered glass)
- Energy creation: Best mix of CO2-free energy sources (solar power, geothermal heat and hydrogen*）
Installed the first Hydrogen production, storage and power generation system for a private business in Japan
Green Infrastructure Demonstration Facility
In March 2018, we established a green infrastructure* demonstration facility within our Institute of Technology, to promote sustainable community development, including disaster prevention/mitigation and biodiversity conservation through utilizing the functions of the natural environment, and are verifying the effectiveness of the facility.
We will proceed with the advancement and improvement of technologies related to green infrastructure factors based on the collected experimental data, and plan to push forward with proposals for the installation of green infrastructure facilities, which are expected to see further utilization in urban areas in the future.
Green Infrastructure: A concept and methodology that proactively incorporates the functions and mechanisms of nature that are useful for humans and environmental conservation in infrastructure (social capital) development and land use.
Initiatives for Biodiversity
We added “Biodiversity Conservation” to our environmental policies in July 2010, and implement a variety of initiatives based on these policies. Regarding biodiversity, we will continue pursuing initiatives such as biodiversity conservation activities, cooperation with relevant local communities and the development of environment-friendly technologies.
Ecological Corridor Simple Evaluation Tool (CSET)
We developed the Ecological Corridor* Simple Evaluation Tool (CSET) under the guidance of Professor Akira Tanaka of the Landscape Ecosystems Lab, in the Department of Restoration Ecology and Built Environment, Faculty of Environmental Studies at Tokyo City University, with the aim of developing an ecosystem network evaluation system that is useful in biodiversity-conscious urban planning. CSET is a tool for the simple assessment of biodiversity potential in urban areas.
We utilize the results of analysis by CSET, mainly in bidding proposals.
Ecological Corridor: A corridor-like habitat that continuously connects important bases where migratory wildlife can travel.
