Natural Capital and Biodiversity

The ID&E Group has been engaged in global water resource development since its foundation, and water resource conservation and efficient utilisation is a high-priority sustainability challenge. We have established Action Guidelines for the Conservation of Water Resources within our Sustainability Management Framework. Based on these Action Guidelines, we earnestly pursue water resource conservation, contributing to our Group's material topic of Cultivating a Beautiful and Habitable Planet.

Nippon Koei, in collaboration with the University of Tokyo Graduate School of Engineering and Suntory Holdings, has developed an online platform, “Water Security Compass,” which enables the multifaceted visualisation of water scarcity risks. By taking into account water supply–demand balance and regional characteristics, the platform allows users to identify future water resource risks. Currently, a Global version (beta) and a Japan version (alpha)—which analyses water resources across Japan at high spatial resolution—have been released. Through the proprietary indicator SS‑DTA, the platform contributes to water resource conservation, including responses aligned with the TNFD framework.

NK LAC participated in the Panama Bay Sanitation Project, contributing to the design of wastewater treatment plants and capacity expansion. Through advanced biological treatment processes and biogas power generation, the project has achieved improvements in water quality and reductions in CO₂ emissions, thereby contributing to the conservation of coastal ecosystems. In addition, the project promotes awareness of water resource management through an environmental education facility, supporting initiatives to build a sustainable future.
