2026.10.07
TOKYO, Japan — Kumagai Gumi Co., Ltd. (Head Office: Shinjuku-ku, Tokyo; President: Shin Ueda) submitted an application to revise its greenhouse gas (GHG) emissions reduction targets to the Science Based Targets initiative (SBTi)※1, an international environmental initiative, and has now received re-validation under the "1.5℃ target" and "Net-Zero Standard."
In its business strategy and ESG Initiatives, the Group positions addressing environmental issues, including climate change, as a critical management task. Since receiving SBTi validation at the "Well-below 2℃" level in 2021, the Group has worked to reduce greenhouse gas emissions at construction sites and across the entire value chain. Furthermore, ahead of the five-year re-validation application required by the SBTi, the Group raised its reduction target to the "1.5℃ target" in 2024 and promoted reduction activities.
This SBTi re-validation is approved as targets grounded in science in accordance with the SBTi's latest standards. The Group as a whole will continue to accelerate initiatives toward the "1.5℃ target" and "Net-Zero Standard", aiming to achieve a sustainable society and improve long-term corporate value through technological innovation and partnerships with partner companies.
