For Realization of a Nature Co-Existing Society

Policies and Basic Approach

The TAISEI Group has established the Group's long-term environmental target "TAISEI Green Target 2050" to "Realization of a Sustainable and Environmentally Friendly Society" as stated in the Environmental Policy, which defines our responsibilities, contributions through our business and initiatives toward the realization of a nature co-existing society. The "Fundamental Concept" is described in the Environmental Policy.

Responsibilities

As construction is the core business of the Taisei Group, the Group has a keen awareness of the effect of its business activities on the transition to a nature -co-existing society and the impact of the transition to a nature -co-existing society on business activities. We observe the Declaration of Biodiversity Preservation by Taisei Group and consider it to be our responsibility to minimize the negative impact of construction business on the natural environment and biodiversity.

Contribution Through Our Business Activities

The Taisei Group identifies the risks and opportunities in anticipation of the achievement of a nature co-existing society. We strive to develop and disseminate technologies and services relating to conserving and restoring natural environments and enhancing biodiversity, and to promote activities that, co-exist with nature and maximize the positive impact on the natural environment and biodiversity, in order to contribute to the realization of a nature co-existing society.

Risks and Opportunities

There are concerns that construction work will have a significant impact on the natural environment and biodiversity. For this reason, we provide customers with solutions that consider the natural environment and biodiversity and create a rich environment throughout the planning, design, construction and post-completion building operation stages. At the planning and design stages, we respond appropriately to environmental laws and regulations, create added value related to the conservation of the natural environment and biodiversity; at the construction stage, we work in consideration of the natural environment and biodiversity; and at the completion stage, we provide operational and management support to conserve the natural environment and biodiversity.
We will contribute to the realization of a nature co-existing society by properly evaluating the value of natural capital, minimizing the impact of construction work as much as possible, and providing technologies to preserve the natural environment and restore and create biodiversity.

Participation in Initiatives

The Tokyo Greenship Action project

Since FY 2003, the Tokyo Metropolitan Government Environment Bureau has conducted activities to preserve natural environments in cooperation with private companies, NPOs, governments and so on in several of the 50 regions of Tokyo Prefecture that have been designated as “conservation areas,” and uses these areas as venues for the Sustainability activities of private companies. Taisei is in agreement with this initiative, and for more than 10 years the company has participated in the Tokyo Greenship Action project to preserve greenery in Nanakuniyama.

The Japan Business Initiative for Biodiversity (JBIB)*

The JBIB is an organization of companies set up in 2008 to promote active efforts aimed at preserving biodiversity. As a member of the JBIB network, Taisei promotes activities to preserve biodiversity by sharing information regarding the Promotion Guidelines for ABINC registered company and the Association for Business Innovation in harmony with Nature and Community (ABINC) and communicating with member companies.

Eco-First Commitment
Participation in Eco-First Council

In May 2012, TAISEI Corporation submitted to the Minister of the Environment an Eco-First Commitment and was certified as an Eco-First Company, and the company is steadily executing its commitment. TAISEI serves as the coordinator of the Eco-First Promotion Council which is made up of the 54 (as of March 2023) companies that have been certified as Eco-First Companies. We are working to strengthen cooperation with the Ministry of the Environment and the other Eco-First Companies to resolve environmental issues such as achieving carbon neutrality, a circular economy and nature positivity.

Activities / Efforts

Natural environments consist of a variety of interconnected environment ranging from remote mountains and satoyama (undeveloped woodlands near populated areas) to cities and the sea. TAISEI Corporation is working to preserve and create diverse good natural environments and green infrastructure in order to achieve and deepen nature positivity.

Promotion of Green Infrastructure

Shinagawa Season Terrace

The Shinagawa Season Terrace is a building complex that effectively uses the land above the site of the Shibaura Water Reclamation Center. To ensure that contaminated rainwater does not flow directly into the ocean, a rainwater storage pond was constructed beneath the Water Reclamation Center to temporarily hold the water that falls initially during torrential downpours. In addition, the artificial ground that was built at ground level has been provided with a vast green area that cools the breezes blowing from Tokyo Bay before they reach the city center. This open space of water and greenery forms a green infrastructure that makes use of water, wind and greenery.

Taisei Group Guidelines for Conservation of Biodiversity

The Biodiversity Guidelines constitute guidelines for action in three major areas: company-wide activities, planning and design activities, and procurement and construction activities. By proposing and deploying water resource and biodiversity-related technologies, we are working to reducing the consumption of water resources and reducing the environmental impact of construction in accordance with the guidelines.
we also provide employees with regular environmental training and conduct environmental preservation activities in order to contribute to society.

Biodiversity-Conscious Research, Planning, Construction and Monitoring

Taisei Corporation has adopted a system for identifying risks relating to biodiversity at the construction planning stage and following up on them throughout the entire process from construction through completion. Taisei's ecological planning, one of the company's proprietary environmental planning technologies, has been formulated and executed in all projects in which consideration for ecosystems is judged to be needed.
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.
These tools make it possible to easily determine the environment at construction sites and share this information to appropriately preserve and create natural environments.

Natural Environment Conservation

Initiatives for Sustainable Virtuous Cycles in Local Communities Implemented by the Taisei Group

We jointly participated in the activities to build a forest circulation system for the H1 Building of the Oki Honjo Plant. For the facility, we actively used timber from the Arakawa River basin in Chichibu. We are also engaged in a tree planting initiative by bearing part of the cost to reforest the area where timber has been sourced. We are contributing to forest recycling by working with our customers and local communities to recover forests and recycle forest resources for the future.

Environmental DNA

With DNA analysis technology derived from organisms contained in water and soil, we conducted a continuous habitat survey of rare amphibians (salamanders, etc.) living in the conservation target areas around construction sites. This analysis technology enables continuous monitoring of the underwater inhabitation status after the spawning season, which was difficult with conventional visual surveys.

Creating forests from saplings designed to resemble a natural forest

In the development of Fujisan Nanjyo Industrial Park, trees suitable for the regional environment were used to conduct "10-year forest creation" designed to resemble a natural forest. Saplings were planted in a tree-planting ceremony, using "nature-conscious greening" techniques to nurture a forest with trees that compete with one another. It has been confirmed that, ten years after planting, a forest has been formed with richer biodiversity than the remaining forest that surrounds it.

Preserving and Creating Natural Environments to Achieve Nature Positive

Kure City General Waste Disposal Site

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.
To preserve living things that have been lost to development in the satoyama environment, a preservation plan was drafted based on surveys, and a compensatory biotope was created. A subsequent survey confirmed the presence of the living things that were the objects of conservation.

Sapporo Dome (Sapporo City, Hokkaido)
Ongoing monitoring survey

In the planning stages for the construction of Sapporo Dome in 1997, consideration for nature was one of the design conditions, as the site that was planned for construction was adjacent to a residential area and Hitsujigaoka, a place with a rich natural environment. Accordingly, with the aim of creating an environment that would be used by an even more diverse array of living things, ecological planning techniques were used to propose planning conditions and create a bio-friendly outdoor facility plan.

Long-term monitoring was initiated when the facility was put into operation in 2001 and has continued to this day. Monitoring has confirmed the presence of many varieties of birds that had been set as indicators. Moreover, the varieties of birds, butterflies and dragonflies have increased since the planning stages, and biodiversity is even greater than before construction began, confirming that the created environment is contributing to nature positivity.

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.

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.

Creating Nature in Urban Environments

Otemachi Tower and Otemachi Forest

A natural forest designed to match the character of the location was created in the center of Tokyo to restore both the city and nature. Otemachi Forest provides multifaceted functions as a part of the green infrastructure of the urban sphere. It offers a place of rest and relaxation to people coming and going in the business district, helps to ease the "heat island" phenomenon, and contributes to the ecosystem network.

The Okura Tokyo

The Japanese aesthetics that have been refined since ancient times were used as the concept for the design of the exterior space. These aesthetics will carve out a new history as regional scenery that creates new value for society.

Restoring Ocean and Water Environments

Eelgrass transplantation technique

This is a simple transplantation technique for eelgrass (Zostera marina) that requires no seeding or stock planting. A mat made of palm fibers is placed in a natural eelgrass bed, and eelgrass seedlings fall naturally onto the mat and sprout, anchoring themselves to the mat. The mat is then simply moved to the transplantation location. In ocean tests, this method has been confirmed to achieve propagation and growth that is equivalent to that of natural eelgrass.

Coral transplantation technology

Coral sea and coral growing on
an implantation device

This technology uses coral egg-laying to induce propagation. Incubated and hatched coral larvae are colonized to implantation devices to propagate. TAISEI has developed a concrete implantation device that is cheaper than conventional ceramic implantation devices. These devices can be used to preserve and create highly diverse coral reefs in the same manner as natural coral reefs are created.

Consideration of Biodiversity for Proposal (risk assessment)

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.

Mori Concierge^®:Our unique tool enabling the selection of plants that can adapt to the environment of a planned site.
Mizube Concierge^®:Our tool for developing a unique plan to conserve and compensate for waterside rare fauna and flora whose ecosystems may be affected by construction.

Dialogue and Cooperation with Stakeholder

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 3,358 dormouse nest boxes, thus far.
In addition, we participated in crowdfunding for an animation project to raise awareness about roadkill issues related to small arboreal animals and animal pathways. This anime, "Promise of the Forest: Yamane's Tale," which raises awareness about animal pathways, was released in August 2023.

TAISEI 1 Ton CLUB

In 2012 and 2015, we supported the Kamaishi Forest Owner's Association, which manages the mountain forests of Unosumai District. In May 2017, a large-scale wildfire occurred in the district due to a suspicious fire, resulting in the burning of 413 hectares as well as heavy damage. Therefore, since 2017, we have been conducting in-house fundraising to collect donations to purchase seedlings to revive forest in Kamaishi. For FY2023, we gathered 1,538,500 yen in voluntary donations from 1,115 employees.
