For Realization of a Nature Co-Existing Society

Policy and Management

The Taisei Group has set forth “Promoting environmental conservation and creation” in the Action Guidelines for Taisei Personnel and the Taisei Group as a Whole, and clearly stated that it recognizes the importance of environmental issues and actively works to promote environmental conservation and creation with a view to realizing a harmonious coexistence between nature and human beings.
As one of the 2050 Targets, Taisei Corporation has committed to “Minimizing impact on natural capital” in its 2050 Environmental Targets “TAISEI Green Target 2050.” To achieve this target, we set the goal of implementing 35 or more proposals that take biodiversity into consideration, using such means as our unique biodiversity evaluation tools, the Concierge Series. We identify risks at the construction planning stage and, through the cooperation of related internal departments including the design division, building construction/civil engineering work division and the Taisei Advanced Center of Technology, use the various technologies owned by the Taisei Group to minimize the adverse impacts on biodiversity of the local area. In order to clarify its corporate stance on the conservation and creation of biodiversity, Taisei Corporation has agreed to the Declaration of Biodiversity by Keidanren (Japan Business Federation), and formulated the Declaration of Taisei Corporation on Biodiversity Preservation in 2010. Since 2020, we have been supporting Declaration of Biodiversity by Keidanren and Action Policy (revised edition).

Risks and Opportunities

There is concern that construction work will always have a significant impact on the surrounding environment, including nature. At the planning stage, we identify risks, including violations of environmental laws and regulations, and opportunities to create added value. From the design and construction stage to the operation and management support after completion, we provide our customers with solutions that help create a rich environment while giving consideration to biodiversity.
We will contribute to the realization of a society in harmony with nature by appropriately evaluating the value of natural capital, utilizing it for infrastructure development and building planning, and minimizing the impact of construction work.

Promotion Framework

EMS's Organizational(EMS)

Taisei Corporation operates an Environmental Management System (EMS) based on ISO14001 on a company-wide basis. We have established an Environmental Committee, chaired by the President, which deliberates and decides on environmental policy and environmental targets that are important for environmental management, in addition to medium- and long-term targets and environment-related initiatives that lead to external evaluations.

Biodiversity-Conscious Research, Planning, Construction and Monitoring

Taisei Corporation has adopted mechanisms for identifying risks relating to biodiversity at the construction planning stage and following up on them throughout the entire process from construction through completion. For projects in which consideration for ecosystems needs to be emphasized, Ecological Planning — Taisei's proprietary environmental planning technique — is employed to propose appropriate conservation measures to the client based on research and analysis, such as plans that contribute to coexistence with nature, in order to achieve preservation and restoration of suitable natural environments.
Ecological Planning is the equivalent of the Biodiversity Action Plan (BAP) in the Convention on Biological Diversity. Taisei uses its various technologies to study and analyze the environment at the construction site and the surrounding area, and then drafts and executes a plan based on regional characteristics in an effort to construct good quality social capital. Monitoring is conducted following completion and the results are used as feedback for technological improvement.
Taisei has also developed the Concierge series of proprietary biodiversity assessment and planning tools. These tools allow anyone to easily determine the environment at construction sites and share this information to appropriately preserve and create natural environments. We also conduct monitoring and predictive assessments. In 2020, Taisei developed Mizube (waterfront) Concierge, the third in its Concierge series of tools following Ikimono (living creatures) Concierge and Mori (forest) Concierge. Deploying these tools for projects in which endangered species need to be protected will help to achieve a society that is in harmony with nature.

[ Award ] Initiatives for Nature in Fujisan Nanryo Industrial Park Received the Environmental Award of the Japan Society of Civil Engineers and ENAA’s Engineering Commendation Award

Fujisan Nanryo Industrial Park
Development Project

Under the theme of “a manufacturing base where greenery, people and production come together,” Taisei Corporation is carrying out the Fujisan Nanryo Industrial Park (Eco-Factory Mt. Fuji) development project in Fujinomiya City located at the south foot of Mt. Fuji.
Developing the Fujisan Nanryo no Mori FSPJ scheme, a sustainable action to nurture forests in collaboration of industry, government, academia, and local people, we have supported nurturing forests for more than ten years from completion of construction. This is a pioneering initiative to balance economic activity and harmonious coexistence with nature in that it adopts forest nurturing methodology from a medium- to long-term perspective and business model with forest as its theme. We intend to utilize and deploy this as a tool to realize a nature co-existing society. This initiative was praised externally, and received the 2020 Environmental Award of the Japan Society of Civil Engineers (Group-2) and the 2020 Engineering Commendation Award of ENAA (Environmental Contribution).

Biodiversity Conservation and Creation cases

Long-term monitoring surveys
The Sapporo Dome

In the construction of the Sapporo Dome, which was completed in 2001, right from the planning stage, we used our environmental planning technology to plan an external structure that emphasized the conservation of biodiversity. The technology employed in this project was Ecological Planning, Taisei Corporation's proprietary environmental planning tactics, which facilitates the design of spaces that preserve the region's inherent ecosystems from the planning stage.
In order to verify that the environment is actually inhabited by various types of living creatures, we have conducted long-term monitoring surveys based on the number of species of birds, butterflies, dragonflies, and other creatures, from the planning stage in 1997 to the completion of construction in 2001, at both 3 years and 10 years after construction, and also in the present day.
Knowledge and concrete results accumulated during this process have been used for the development of the biodiversity communication tools, the “Ikimono (living creatures) Concierge,” and have contributed to the conservation and sustainable use of natural resources through various environmental awareness activities conducted by Sapporo Dome Co., Ltd.
These initiatives were recognized as “Sapporo Dome ECOMOTION and Taisei Ecological Planning” as an affiliated project of the “Japan Committee on UNDB” Japan Committee on UNDB(United Nations Decade on Biodiversity).

Improvement of Facility Value through Biodiversity Conservation and Creation
The ESR Amagasaki Distribution Center

An environmental certification that proves natural environmental consciousness of a facility increases the value of the facility and appeals to customers as proof of an environmentally conscious company.
Leveraging its strength as a general construction firm capable of executing projects from start to finish, from the planning and design of facilities to their construction, Taisei Corporation conducts environmental assessments of projects, including the impact on biodiversity, from the early stages of development planning, and incorporates consideration for the environment into project plans. In so doing, we strive to minimize environmental impacts and support our clients' environmental activities, such as the conservation and creation of biodiversity as well as the acquisition of environmental certifications.
At the stage of planning and design of the ESR Amagasaki Distribution Center (ordered by ESR), a logistic facility located at the Osaka bay-side area, for example, an outer green area was planned, designed, and constructed by Taisei Corporation to help improve the biodiversity without affecting capabilities as a logistics facility.
The facility earned the “Business Innovation in Harmony with Nature and Community” certification from the Association for Business Innovation in Harmony with Nature and Community (ABINC) as a logistics facility that respects biodiversity.

ESR Amagasaki Distribution Center (ordered by ESR)
Eco Globe Kure Biotope (Kure City, Hiroshima)

The general waste final treatment plant, Eco Globe Kure, was completed and began operations in 2015 as a place to express and communicate nature restoration technologies. We recreated the waterside environment that was going to be lost with the construction of the treatment plant and created a biotope inhabited by diverse flora and fauna, including rare species.

Consideration of Biodiversity for Proposal (risk assessment)

Mizube Concierge

During civil engineering construction, there are many chances to face the natural environment. Therefore, we propose measures to protect endangered animals and plants and avoid having an influence on them considering biodiversity. As for construction, our biodiversity evaluation tools such as “IKIMONO-Concierge®” “MORI-Concierge®” and “Mizube-Concierge®” are effectively used for greening plans at construction sites or for redevelopment projects.

  • *Ikimono Concierge:Our unique tool for predicting and identifying animals that can be attracted by a planning site
  • -Mori Concierge: Our unique tool enabling the selection of plants that can adapt to the environment of a planning site
  • -Mizube Concierge: Our tool for developing a unique plan to conserve and compensate waterside rare flora and fauna whose ecosystems may be affected by construction

Implementation of Activities to Contribute to Environment and Society in Cooperation with Various Stakeholders

Our approach to enhancing biodiversity is guided by Environmental Policy and Declaration of Taisei Corporation Biodiversity Preservation, and demonstrated as a company-wide activity to reduce environmental impact under our unique biodiversity conservation guidelines, etc. Not limited to biodiversity consideration in the business, our efforts include offering volunteer opportunities for the Group employees and their families to make nest boxes for dormice as part of natural environmental education through forest conservation activity, and to participate in Tokyo Greenship Action for more than ten years.

*1Tokyo Greenship Action Participated in the “Tokyo Greenship Action,” a nature conservation program hosted by Tokyo Metropolitan Government.

The Taisei Group Environmental Volunteers

1) Making dormouse nest boxes

Since 2004, Taisei Corporation has participated in the Animal Pathway (bridges for tree-dwelling rodents) Research Society, and has supported ecosystem conservation activities for tree-dwelling rodents, such as the dormouse, through development and facilities for animal pathways and monitoring. As part of these activities, our group employees and their families participate every year in volunteer activities to construct dormouse nest boxes. In our activities held, we donated these boxes to the Dormouse Museum of KEEP, Inc.
We have conducted this environmental volunteering activity every year, with participants working to build a total of 2,945 dormouse nest boxes, thus far.


Since 2010, we have conducted this environmental contribution activity a total of 9 times, under the theme of “simultaneously achieving carbon offsets at the Company and in the homes of employees.”
In 2012 and 2015, we supported the Kamaishi Forest Owner's Association, which manages the mountain forests of Unosumai District. On May 9, 2017, a large-scale wild fire occurred in the District due to a suspicious fire, resulting in the burning of 413 hectares as well as heavy damage. Accordingly, we continued our support through fundraising to donate the cost of planting saplings for the reforestation of Kamaishi Forest. We were also involved in the construction of Kamaishi Unosumai Memorial Stadium, where trees that had been felled by the fire in Unosumai District were used to make wooden seats, public toilets, benches and louvers sunshades.
