Komatsu Ltd. (hereafter “Komatsu”) (President and CEO: Takuya Imayoshi) has decided to issue a green bond (unsecured straight bond) through a public offering in the Japanese market. The proceeds raised through this issuance are planned to be used for expenditures related to the construction of Komatsu’s new headquarters building (*1), which is currently under construction. The building is designed with consideration for reducing CO2 emissions and received ZEB Ready (*2) certification in April 2026.
This issuance marks Komatsu’s third ESG bond, following the green bond issued in 2020 and the sustainability-linked bond issued in 2022. It forms part of its initiatives to address environmental issues through financing activities. In connection with this issuance, Komatsu updated its “Komatsu Green Finance Framework” (*3). Under the previous framework, eligible projects covered initiatives contributing to the company’s management goals, including CO2 emissions reduction in production, CO2 emissions reduction in products, and the use of renewable energy. With this update, Komatsu has newly added properties with green building certifications, including ZEB Ready certification, to the list of eligible projects.
Through this bond issuance and future ongoing green finance initiatives, Komatsu will allocate the funds raised to efforts that contribute to resolving issues with significant impacts on its business activities as well as the environment and society, thereby further accelerating its initiatives toward the realization of a decarbonized society.
