By referring to Aqueduct tools and databases developed by WRI (World Resources Institute), the Marubeni Group identifies regions of which water stress level is “high” or more (“relevant areas”), and through internal reviews such as Sustainability Survey, we survey the amount of water withdrawal from the relevant areas. Thirty-one operation sites that have been identified by the Sustainability Survey with aggregated data as of the end of March 2024, operate in the watershed areas of Gulf Coast, Mississippi-Missouri, Rio Grande-Bravo, Saskatchewan-Nelson, Kansas, California, Texas, Minnesota, North Carolina, North Dakota, lowa in North America, with relatively high water stress. There is a total water withdrawal of 113 thousand ㎥ in these regions, and we are aware that this is equivalent to less than 0.1% of 134,144 thousand ㎥, the amount of water withdrawal for the whole Marubeni Group excluding the portion used for hydroelectric power. (Furthermore, we have confirmed that no operation sites face comprehensively high water risk, such as the amount of physical water resources, pollution by wastewater, regulations, or assessment of nearby regions.)
In FYE 3/2025, there were no legal or regulatory violations related to water withdrawal and water discharge at the major operating companies of the Marubeni group. In addition, there was one case in FYE 3/2023, and two cases in FYE 3/2024, both of which have been corrected.
Iguacu Vietnam Company Limited is Marubeni’s consolidated subsidiary.
Costs for water management in FYE 3/2024 are as follows: ・Costs associated with water-related risks: 2,852.8 million yen. (These include maintenance and repair of water withdrawal and drainage systems and recycling treatment facilities, installation of water-saving equipment, purchase of water discharge treatment chemicals, emergency response training for scenarios assuming the outflow of hazardous substances, and implementation of cleanup activities in the areas surrounding water sources.) ・Investments in R&D to mitigate water-related risks: 19 million yen. (These are R&D expenses for water risk aversion to maintain water quality, to ensure water quantity and to investigate the surrounding environment.)
We have an established system to report/correct cases related to administrative guidance and non-compliance with laws/ordinances in the operation of the Environment Management System. The measures are taken to prevent recurrence.
