Disclosure of Climate Change-Related Information
(Disclosure in line with the TCFD Recommendations)
Kajima recognizes that addressing environmental issues including climate change is a key management issue and includes “providing technologies and services for disaster preparedness that support safety and security” and “contributing to society’s transition to a carbon-free footprint” among its material issues. In December 2019, Kajima expressed its support for the recommendations of the Task Force on Climate-related Financial Disclosures (TCFD).
While society and markets are increasingly committed to decarbonization, the world is already experiencing extreme weather events and floods that are becoming more severe. We will continue to contribute to the resolution of social issues related to climate change through our businesses. This includes contributing to the social mission of the construction industry in terms of disaster prevention and mitigation, BCP and disaster recovery.
Kajima has established the Environment Committee as an organ to deliberate and decide on environmental issues. The committee is chaired by the President and comprises members from the management team and executives from domestic and overseas subsidiaries and affiliates. It deliberates and decides on important environmental policies and measures, including measures to address climate change. Important policies are then deliberated and decided on by the Board of Directors and the Management Committee. The policies and measures decided on are incorporated into each division’s business plan and implemented. The next year, the Environment Committee follows up on progress and results, thereby leading to further improvements and new initiatives. The carbon neutral policies discussed by the committee have been integrated as priority initiatives in Medium-Term Business Plan (FY2021–2023). The Board of Directors regularly follows up on the implementation of initiatives.
The construction industry uses materials that conventionally emit a large amount of greenhouse gases during manufacture, such as cement and steel, and the long operating life of buildings and structures has a significant impact on the greenhouse gas emissions of customers. Accordingly, public policies related to carbon pricing and carbon emissions, zero energy buildings (ZEB) and renewable energy-related construction markets, and low-carbon construction technologies are identified as highly relevant transition risks and opportunities. Due to the social mission of the construction industry, which includes contributing to disaster prevention and mitigation, as well as the frequent outdoor work characteristic of the industry, the impact of changing weather patterns, the intensification of extreme weather events, the effect of rising temperatures on labor productivity, and corresponding labor legislation are identified as physical risks and opportunities.
In March 2021, Kajima revised the setting of the 2°C scenario to a 1.5°C scenario and estimated the impact on domestic construction projects in fiscal 2030.
- 1.5°C scenario※1
Scenario in which strict measures are taken against climate change, and the temperature increase in 2100 is limited to about 1.5°C above pre-industrial levels.
※1 Parameters used to calculate impact are based on the Sustainable Development Scenario in the World Energy Outlook 2018, International Energy Agency (IEA),Japan’s Long-term Strategy under the Paris Agreement, Japan’s Ministry of the Environment, and other references.
- 4°C scenario※2
Scenario in which strict measures are not taken against climate change, and the temperature increase in 2100 reaches about 4°C above pre-industrial levels.
※2 Parameters used to calculate impact are based on The Aqueduct Global Flood Analyzer, World Resources Institute (WRI), Working on a warmer planet, International Labour Organization (ILO), and other references.

To address climate change-related risks, the Global Environment Office of the Environmental Engineering Division, which serves as the secretariat for the Environment Committee, leads cross-organizational assessments of the environmental impact of climate change-related risks by the Environmental Management Subcommittee and other relevant internal departments. Finally, the Environment Committee deliberates and decides on risks and opportunities each year.
All operational risks, including climate change-related risks, are assessed by the Compliance and Risk Management Committee, which is chaired by the President, and reported to the Board of Directors twice a year. In addition, Kajima is working to further improve its disaster preparedness and business continuity capabilities through means such as practical BCP drills for torrential rain and other scenarios.
Indicators and Targets
In 2013, Kajima formulated and announced the Kajima Environmental Vision: Triple Zero 2050 as the basis for environmental initiatives. At the same time, Kajima is implementing activities under Target 2030, which sets specific quantitative milestones for fiscal 2030.
In 2021, Kajima revised its CO2 reduction targets and aims to reduce the amount of CO2 emitted during construction (Scope 1 and 2) by 50% compared to fiscal 2013 by fiscal 2030, and to reduce CO2 emitted during construction (Scope 1 and 2) to virtually zero and achieve carbon neutrality by fiscal 2050.
Kajima manages its environmental activities by assessing climate change-related risks and opportunities and reviewing indicators and targets every three years based on this environmental vision. The period for environmental targets is synchronized with the medium-term business plan. Kajima thus aims to increase corporate value and solve environmental issues in an integrated manner.
