Information Disclosure Based on TCFD Recommendations

The safety and security of our daily lives are being threatened by climate change and the resulting increase in the frequency and severity of natural disasters. These change brought produced a major movement toward decarbonization that began with the Kyoto Protocol and continued with the adoption of the U.N. Sustainable Development Goals (SDGs) and the Paris Agreement. This movement has had a major impact on policies in Japan and other countries around the world, and also increased expectations for the role that companies should play in this effort.

The Taisei Group regards the impact of climate change on its business as a crucial management issue. In July 2020, we endorsed the TCFD recommendations, and since May 2021 we have been disclosing information in accordance with the recommendations. In response to the partial revision of the Annex to the TCFD Recommendations in October 2021, we identified risks and opportunities under the 1.5°C scenario and conducted a study of the climate-related indicators related to the recommendations, and partially updated our disclosed information.

Environmental Policy

Taisei's Environmental Policy was revised in March 2023 to clearly state in "Fundamental Concept"
achievement of the Group's long-term environmental targets as its responsibility, and contribution to the realization of a decarbonized society, a recycling-oriented society, and a nature-co-existing society through its business activities.

Environmental Policy (excerpted)

Fundamental Concept
Based on the Taisei Group Philosophy “To create a vibrant environment for all members of society” and our Fundamental Policy on Sustainable Development, the Taisei Group strives to build good quality social capital through corporate activities centered on construction business in harmony with nature.
As the Group having construction as its core business, we aim for the “Realization of a Sustainable and Environmentally Friendly Society” by recognizing environmental issues as our significant sustainability tasks and fully understanding the impacts of our business activities on the environment, and environmental impacts on our business activities. It is our mission to achieve our Group’s long-term environmental targets in compliance with environment-related laws and regulations.
In addition, we will identify the “Environment-Related Risks and Opportunities” including climate change in particular, develop and promote environment-related technologies and services, and contribute to the realization of a decarbonized, recycling-oriented, and nature co-existing society through our business activities.
Group’s Long-Term Environmental Targets
The Taisei Group established a long-term environmental target (TAISEI Green Target 2050) to achieve the “Realization of a Sustainable and Environmentally Friendly Society” as outlined in the Fundamental Concept above. We will work with the whole supply chain, together with the stakeholders to achieve these environmental targets by defining our “Responsibilities”, “Contributions Through Our Business”, and “Achievements” to confront the three types of societies as “Decarbonized Society”, “Recycling-Oriented Society”, and “Nature Co-Existing Society”, and to address the two individual issues as “Forest Resources/Forest Environment” and “Water Resources/Water Environment”.
Continuous Implementation of Environmental Due Diligence
Toward the “Realization of a Sustainable and Environmentally Friendly Society” as outlined in the Fundamental Concept above, we will establish and continuously implement environmental due diligence system following the international standards such as the “OECD Due Diligence Guidance for Responsible Business Conduct”. Throughout its operation, the measures are reviewed and improved as appropriate.
We make efforts to conduct dialogues and consultations with our stakeholders as appropriate, by utilizing the expertise of external professional institutions regarding the impact of our business activities on environment.

Governance

Organization

A Sustainability Committee and an Sustainability Promotion Committee have been established as an organization to debate issues relating to climate change.

At the Sustainability Committee, which is a committee of the Board, important policies and measures relating to all aspects of environment, society and governance (ESG) are deliberated. At the Sustainability Promotion Committee, which is an advisory body to the Management Committee, basic policy and medium- to long-term targets relating to environmental management are deliberated.

To incorporate a variety of perspectives, the Sustainability Committee is consisted of six directors including the President (of which two are External Members of the Board) Matters are discussed within this committee, after which they are deliberated and resolved at the Board.

Matters deliberated and resolved at the Board of Directors meeting are notified to individual business divisions within Taisei Corporation as well as Group companies, and are reflected in their management plans and business operations. The resolution is also reflected in a specific implementation agenda at construction work offices, and the cooperation of subcontractors and suppliers is also requested.

Organizational Chart of Climate-Related Governance

Executive Officer for Climate-Related Issues

To clarify where the responsibility for promoting sustainability management including climate-related issues lies, a Chief Sustainability Officer (CSO) position, the highest executive officer in charge of sustainability issues, was created under the President, and the CSO was appointed the head of the Sustainability Division (Integrated). The CSO is responsible for promoting sustainability management in business execution, including activities on climate-related issues that have been decided by the Board. The CSO also serves as the Vice Chairperson of the Sustainability Promotion Committee.

Strategies

There are thought to be two types of risks and opportunities associated with climate change. One is the result of "transitions" that include market changes and the tightening of regulations to minimize temperature rise. The other is the result of "physical changes" such as acute abnormal weather occurring due to temperature rise.

To devise business strategies that can deal flexibly with climate change, multiple scenarios are used to identify risks and opportunities and evaluate the impact on business, and then business strategies are formulated and reflected in the Medium-Term Business Plan and the like.

Main Reference Scenarios

Transition Scenarios	International Energy Agency (IEA) World Energy Outlook sustainable development scenario (SDS)… 2°C scenario “Net Zero by 2050 (NZE)”… 1.5°C scenario
Physical Changes	Intergovernmental Panel on Climate Change (IPCC) “Representative Concentration Pathway scenario (RCP8.5)” ... 4°C scenario

Risks / Opportunities

Classification	Risk/Opportunity		Description	Impact level
Transit・on	Market shrinkage and increase in construction cost due to the introduction of carbon pricing and tightened CO₂ emission regulations	Risk	Decrease in private construction investment and equipment investment due to the introduction of carbon pricing and the reinforcement of CO₂ emission regulations Increase in construction costs due to a hike in the prices of building materials and electricity	Medium
		Risk	Increase in costs due to the application of carbon pricing to the CO₂ that is generated by our business activities	Low
	Increase in demand for renewal	Opportunity	Increase in demand for renewal to improve energy efficiency of existing facilities	Medium
	Increase in demand related to energy-saving and renewable energy	Opportunity	Increase in demand related to ZEB and smart cities Expansion of demand for renewable energy-related works such as offshore wind power	Medium
Physical	Increase in average temperature during summer	Risk	Decline in productivity due to an increase in damage to the health (heat stroke, etc.) of skilled construction workers and the avoidance of extremely hot hours Accelerated worker shortage due to the decline in the number of new workers in the construction industry because of the degraded working environment	Medium
	Rise in severity and frequency of natural disasters	Risk	Work suspension, process delay, and increase in labor and temporary work costs due to damage to construction worksites, etc.	Medium
	Increase in severity and frequency of natural disasters	Risk	Increase in procurement costs and process delays due to damage to suppliers	High
		Opportunity	Increase in demand to improve the resilience of equipment and infrastructure against intensified disasters	High
		Opportunity	Increase in new construction and relocation works due to growing demand for relocation from disaster hazard areas	High
	Sea level rise	Opportunity	Increase in the capital investment for improved resilience in areas with a flood risk and demand for relocation from areas with a flood risk	High

Note: Expected impacts on business were categorized into “High,” “Medium” or “Low.”

Climate Change Measures

Measures have been planned to reduce the risks and expand the opportunities accompanying climate change that have been identified through scenario analysis. These measures are reflected in the TAISEI VISION 2030 and the Medium-Term Business Plan (2021–2023).
A roadmap for achieving decarbonization and sustainable growth has also been formulated in order to realise the TAISEI Green Target 2050 which constitutes the Group's long-term environmental targets.

Measures to deal with climate change

Response to the market shrinkage and construction cost increase due to the introduction of carbon pricing and the tightening of laws and regulations		Possession of renewable energy power sources for the purpose of covering the Group’s electricity consumption Examination and introduction of fuel improvement measures (biodiesel fuel/fuel additives) at construction worksites Enhancement of green procurement such as development and utilization of carbon-recycle concrete
Response to the increase in demand related to renewal, energy-saving and renewable energy		Establishment of an organization dedicated to renewal, and expansion of the organization that handles work related to wind power generation Development and commercialization of next-generation high-performance ZEB and the development of energy support services Technological development that contributes to the industries that are expected to grow through a virtuous cycle of the economy and the environment
Response to the reduced productivity of construction worksites due to abnormal weather		Reduction of health damage through the nationwide promotion of wellness worksites and the improvement of working environment during extremely hot hours Consolidate some of the operations of worksites into specialized organizations such as digital product centers Reform the production process at worksites by developing and deploying unmanned construction technology, robot construction technology, etc.
Response to abnormal weather, increase in the severity and frequency of disasters and sea level rises		Advancement of infrastructure development technology for national resilience and the improvement of the proposing skills Development of real-time flood risk prediction/simulation for heavy rain, etc. Securing a business continuity system by building a BCP system with clients and suppliers and conducting regular training

Environment-Related Research and Development Investment

Demand for ZEB buildings is expected to increase in preparation for the achievement of the Japanese government's target of "ensuring energy performance that meets the ZEB standard for newly constructed buildings in 2030". Moreover, demand for environmentally friendly concrete, wooden architecture and other low-carbon and decarbonized construction materials is also expected to increase.

As the market is expected to increase, TAISEI will proactively invest in research and development to secure a market ahead of competing general construction contractors and construction material manufacturers in terms of tschnology development.

Financial Impact

As noted in the Medium-Term Business Plan (2021–2023), we plan to invest JPY 60 billion in environment-related efforts over a period of three years, of which JPY 42 billion is for technology development that contributes to industrial fields where growth is expected through a virtuous cycle between the economy and the environment, and with a competitive advantage. Approximately JPY 23 billion had been executed as of September 2022.

In addition, we raised funds through green bonds and sustainability-linked loans that comply with the green financing framework, and are allocated to investment capital.

Internal Carbon Pricing (ICP)

In 2021, TAISEI introduced the Internal Carbon Pricing system with the expectation of the following three effects. Based on the "Net Zero by 2050 (NZE)" of the International Energy Agency (IEA) etc. the ICP price is currently set at JPY 8,000, and is to gradually increase until 2050.

Expected Effects

Visualize the results and effects of investment and measures that contribute to decarbonization, by converting CO₂ emission reductions into monetary values through the introduction of ICP.
By using the ICP system as an incentive for action that contributes to decarbonization and as a guide for investment decisions, capital investment and technology development that contribute to decarbonization and activities that reduce environmental burden will be promoted, and thus activities toward the achievement of carbon neutrality will be accelerated.
Recognize the potential impact of carbon pricing and prepare for the introduction of a carbon tax, etc.

Risk Management

Based on our Risk Management Policy and the basic regulations for risk management, TAISEI established an overall systematized risk management system under the supervision of the Board. We set up an appropriate management system that also addresses major ESG-related risks such as quality, compliance, information, safety and the environment.

Group-Wide Risk Management

Promotion of Group-wide risk management

Taisei has established a risk management system with the President as chief executive and the general manager of the Business Administration Div. as Chief Risk Management Officer (CRO), and works to ensure ongoing operation of the risk management system to appropriately determine and manage risks relating to business operations. Every year, based on the risks that materialized in that fiscal year, the risk management content for the following fiscal year is reviewed, and the plan-do-check-act (PDCA) cycle is operated and the effectiveness of the risk management organization is verified.

Company-Wide Risk Management System

Business Risks

Risks that may have a significant impact on company operations are reported to the Management Committee and the Board, and the response policy with respect to those risks is studied and determined in a comprehensive manner and reported in "Business Risks" in the Annual Securities Report.

Risk Associated with Climate Change

One of the "Business Risks" is "Risks Associated with Climate Change." The Taisei Group identifies and assesses risk that corresponds to the TCFD Recommendations. A company-wide, cross-sectoral TCFD Working Group (TCFD WG) has been established to identify climate change risks pertaining to the operations of each division and analyze the degree of impact on operations, and to conduct a comparative assessment with risks other than climate change risks and confirm that the necessary countermeasures have been devised. Risks analyzed by the TCFD WG are discussed in the Sustainability Committee and reported to the Board.

These risks are consistent with the risks identified and assessed in the Environmental Management System (EMS) based on the ISO 14001 international standard.

CO₂ Emissions for Taisei Group in FY 2021

More than 90% of Taisei Group CO₂ emissions are Scope 3.
Within Scope 3, the majority of emissions are Category 1 and Category 11.

Category 1: CO₂ emitted during the manufacture of steel materials such as steel frames and steel reinforced bars, cement, and concrete
Category 11: Calculated by multiplying the annual estimated CO₂ emissions by the service life of the buildings delivered during that year.
As the service life varies between 30 and 60 years depending on building use, the result becomes an extremely large figure.
