The Environment

Realization of a Sustainable and Environmentally Friendly Society

Environmental Policy and Environmental Targets

Based on the Group Philosophy “To Create a Vibrant Environment for All Members of Society,” the Taisei Group has set forth in its Environmental Policy and Environmental Targets, the formation of high-quality social capital through corporate activities centered on the construction business in harmony with nature.
The construction industry, which is involved in the formation of social capital, is built on the burden on the environment. On the other hand, environmental problems are becoming more and more serious on a global scale, and long-term countermeasures are required. In response to these circumstances, in 2018 we revised our medium and long-term goals, the 2050 Environmental Targets (TAISEI Green Target 2050), based on environmental issues such as climate change, recycling of resources, co-existing with nature, and environmental pollution risk.
We recognize the “Realization of a Sustainable and Environmentally Friendly Society” as one of our important ESG challenges.
recognizing that the risks and opportunities associated with climate change will have a significant impact on its business strategy, the Taisei Corporation works on scenario analysis, understanding the risks and opportunities that climate change poses to its business, and countermeasure implementation.
In addition, In response to the government's declaration of carbon neutrality in October 2020, we have revised our long-term environmental target, which is a part of the TAISEI Green Target 2050 (see Figure 1 below), as we aim to help achieve a Decarbonized Society with net zero CO2 emissions in the our business operations by 2050.

EMS’s Organizational (EMS)

Taisei Corporation operates an environmental management system based on ISO14001 (hereinafter “EMS”) on a company-wide basis. We have established the Environmental Committee chaired by the President, which deliberates and decides on environmental policy and targets that are important for environmental management, medium- and long-term targets, and environment-related initiatives that lead to external evaluations. Every division and branch has an EMS office that operates under the Environmental Committee, and the environmental staff of each department facilitates and monitors environmental activities, and reflects the results in annual environmental targets. In addition, risks and opportunities concerning the environment are identified in the EMS, with reference to the recommendations of TCFD, in consideration of compliance with related laws and regulations, as well as various internal and external environmental issues including climate change and social demands. As for cross-divisional environmental issues, the CSR Committee(twice a year), Central Safety Committee(five a year), and the like, have been established to discuss initiatives to address them.
In addition, the Taisei Group Environment Promotion Council has been established for domestic Group companies to promote group-wide initiatives.

TAISEI Sustainable Action (TSA)

An Initiative to Reduce Environmental Impact

To achieve its Environmental Policy and Environmental Targets, Taisei Corporation is implementing TAISEI Sustainable Action (TSA), an environmental impact reduction initiative in which all employees participate. In proceeding with this initiative, it is particularly important for many parties involved in construction, which has high CO2 emissions, to be aware of the importance of reducing environmental impact. Therefore, in addition to the “CO2 Zero Action,” which is our basic initiative that has been conducted at all worksites so far, effective specific technologies and activities are summarized in the “Action List,” and the materials, products and technologies used are explained in an easy-to-understand manner with photographs. In addition, the Company has established an award system for activities aimed at achieving the Environmental Targets.
Through this system we evaluate activities to reduce environmental impact, which serves as a model for other divisions, and we work to raise employees’ environmental awareness.

* TAISEI Sustainable Action (TSA)

Company-wide activities to reduce environmental impact including fuel-efficient driving of heavy machinery and vehicles, use of hybrid heavy machinery and renewable energy, development of a wellness conscious greening environment, paperless meetings, and use of LEDs for temporary lighting.

* CO2 Zero Action

An initiative to reduce environmental impact undertaken by all worksites. There are seven actions, including eco-driving of heavy machinery and vehicles, inspection and maintenance, and controlling the temperature setting of air conditioners.

Compliance with Declarations to Society and International Codes of Conduct, etc.


Taisei Corporation strives to improve its environmental performance by steadily carrying out activities based on its Environmental Policy, and by actively disclosing information through the Company's website, the integrated report, and other means. We strive to increase the trust of our stakeholders, and deliver value to them and create sustainable business opportunities. In July 2020, the Company agreed with TCFD(Task Force on Climate-Related Financial Disclosures) and decided to actively disclose information on the impact of climate change on its business activities.
We also participate in environment-related initiatives such as the Science Based Target(SBT) and the Carbon Disclosure Project(CDP).
In addition, we are selected as an "A List" company and "Supplier Engagement Leader" by CDP on FY2020.

United Nations Global Compact (GC), SDGs

The Taisei Group participated in the GC in April 2018 and committed to disseminating and implementing the Ten Principles in the four areas of human rights, labor, the environment, and anti-corruption. At the same time, it is actively participating in various subcommittees sponsored by the Global Compact Network Japan (GCNJ), such as the Subcommittee on SDGs and the Subcommittee on Human Rights Due Diligence (HRDD). In addition, in order to promote business as a member of the construction industry while always being aware of contributions to SDGs, we are working to ensure that SDGs are widely disseminated within the Group and discussing how to reflect them in our business strategies, and the like.

Keidanren (Japan Business Federation)

The Taisei Group participated in the GC in April 2018 and committed to diss
As a member of Keidanren, we respect the content of its Charter of Corporate Behavior and carry out activities toward the “realization of a sustainable society,” which Keidanren aims to achieve. We also participate in the Committee on Environment and Safety, Keidanren Biodiversity Declaration Initiative, the “Challenge Zero” initiative, Global Warming Countermeasure Subcommittee, and Environment Management Subcommittee, which are tackling global warming countermeasures and the formation of a recycling-based society.
We are also on the Nikkenren's taskforce for Voluntary Action Plan on the Environment in Construction Industry, and on its Construction Byproduct Taskforce and Civil Engineering Byproduct Taskforce which contribute to the effective use of resources. In this way, we share information and engage in collaborative initiatives with other companies, thereby contributing to the environmental activities of the construction industry as a whole. In 2014, Nikkenren set construction industry CO2 reduction targets for 2030 and joined Keidanren's Phase II of the Commitment to a Low Carbon Society.
As a member company, Taisei Corporation is making every effort to achieve the target established by Nikkenren of reducing emissions by 25% compared to FY1990 in intensity per value of construction work completed. Specifically, having positioned this as an external requirement of environmental management, we align decisions made in trade associations with our climate change strategy, and after coordinating with each department in charge of environmental issues, the Environmental Committee aligns them with the corporate management strategy.
