For important matters related to climate change, the ESG Promotion Committee, chaired by the President, discusses the issues and then submits reports to the Management Council and the Board of Directors.
Initiatives to address climate change-related risks and opportunities are evaluated annually through the operation of ISO 14001 (Environmental Management Systems) from the perspective of factors that affect the environment, laws and regulations to be complied with, issues in the external and internal environment, and the demands and expectations of stakeholders.
Currently, we are focusing on ISO 14001 initiatives, but we will continue to gather and analyze information related to each of the TCFD’s* recommended disclosure items, as well as gradually enhance the quality and quantity of our disclosures.
* TCFD refers to the Task Force on Climate-related Financial Disclosures. It was established by the Financial Stability Board (FSB) at the request of the G20 and chaired by Michael Bloomberg to review climaterelated disclosures and to make recommendations on how financial institutions should respond.

Scope 1 (Direct emissions of greenhouse gases by the business itself)
-
Scope 2 (Indirect emissions from the use of electricity, heat, and steam supplied by other companies)
In June 2022, we disclosed emissions measured at Company facilities and Company-owned vehicles, and other related areas measured under ISO14001. Starting in June 2023, we have been gradually expanding the scope of emission calculations on-site, including estimates. -
Scope 3 (Emissions of other companies related to the activities of the business)
Disclosures began in June 2023.

As part of our efforts to reduce greenhouse gas emissions, we are working on “ZEB renovation” proposals, design, and construction, as well as verifying cooling technologies for data centers.
Since the acquisition of Company-wide integrated certification in September 2009, we have continued to promote environmental activities centered on ISO 14001. Also, based on our environmental policy of “contributing to the achievement of a low-carbon society by providing optimal solutions to our customers’ demands for energy conservation and CO2 reduction, and through research and development of environmental technologies,” we are actively developing proposal activities to help our customers save energy and reduce CO2 emissions, and aiming to solve environmental issues through our core business.
