The following table shows the amount of water consumed by our business sites in areas identified as having high or very high levels of water stress, using Aqueduct, a water risk map of the world developed by the World Resources Institute (WRI), an international environmental NGO.

*Countries included: Out of the 189 countries included in the ranking of countries with high risk in water-stressed regions, the following 18 countries have been identified as water stress areas related to our business: Qatar, Iran, Kuwait, Saudi Arabia, UAE (United Arab Emirates), India, Oman, Chile, Morocco, Belgium, Mexico, Spain, Algeria, Turkey, Nigeria, Portugal, Egypt and Italy. In some cases, data was obtained directly from the site of the business, while in other cases, data was obtained only from the location of the business's headquarters (parent company/SPC).

Mitsui is participating in the Ras Laffan C power and water desalination (IWPP) project in Ras Laffan Industrial City, located 80 km north of Qatar's capital of Doha. The project was initiated in response to an increase in demand for electric power and water as a result of Qatar's rapid economic growth. Qatar uses seawater desalination to produce 99.9% of its water supplies. In this project, energy efficiency will be optimized through the use of a power generation and desalination process designed to utilize waste heat from power generation. With a power generation capacity of 2,730 MW and desalination capacity of 290,000 tons per day, this project will operate seawater desalination facilities for a period of 25 years starting in 2011. It will supply water and electric power to the Qatar General Electricity and Water Corporation (Kahramaa), accounting for around 24% of Qatar's electricity supply and approximately 14% of its water supply.

Chile accounts for approximately 30% of the world's copper production and is a thriving copper mining region. The country's copper mining operations use large amounts of water, especially in the north of Chile where there is a high concentration of mines. Water stress is high in this region as a whole, with growing concerns about resource shortages. Mitsui has invested in a seawater desalination and pumping service operation for the Spence Mine, a 100% subsidiary of BHP, a major mineral resources company, through Caitan S.p.A., established as a 50-50 joint venture with Técnicas de Desalinazación de Aguas, S.A. (Tedagua) under the ACS Group of Spain. Caitan S.p.A. will construct, own and operate a water desalination plant and a 150 km water pumping facility in the province of Antofagasta in the north of Chile to supply fresh water to copper mine operator Spence over a 20-year period.
In the north of Chile, demand is expected to grow at an annual rate of around 14% as the region as a whole becomes increasingly concerned about water shortages. We will contribute to Chile's development by tapping into the country's rapidly growing demand for water infrastructure and further developing related infrastructure, while addressing the issue of water shortages through our business.

Efforts to Care for Water Resources During Shale Gas Extraction

Through its investee, Mitsui E&P USA LLC, Mitsui is engaged in the Marcellus shale gas development and production project and the Eagle Ford shale oil/gas development and production project. The oil and gas are extracted using hydraulic fracturing (fracking), and Mitsui E&P USA gives due care to water resources by ensuring that water for hydraulic fracturing (fracking water) is properly used (including the recycling of wastewater), managed, and discharged.

Efforts to Improve Water Usage Rates in the Copper Business

We are engaged in the copper mining business in Chile. Chile is a high-risk region in terms of water stress levels, but because the operations require a large amount of water, we are promoting the introduction of technologies to maximize the efficiency of water use in the operating processes of each mine and are working to reduce the amount of new water withdrawal. At the Los Bronces copper mine (located in the Capital Province of Chile), in which we are engaged together with Anglo American Plc, we reached a water reuse rate of 85% in 2020, mainly due to efforts to extract and reuse water from tailings. Also, at the Collahuasi copper mine (located in the Tarapaca province), the second largest copper mine in Chile by production volume, with Anglo American and Glencore as partners, the water reuse rate reached level of 76% in FY Mar/2020. In addition, we are planning to build a seawater desalination plant in the future. We will continue to contribute to the development of the country through our business while making efforts to conserve water resources.

Efforts to Reduce Water Use and Recycle Effluents - Improving Water Efficiency in Offices

At the Head Office, we use 100% recycled drainage water for toilet flushing in order to promote reduction in water consumption. In addition, we have set the goal of improving water use efficiency by reducing the amount of water used at the Head Office and at our own buildings (Osaka) to less than the amount used in the previous fiscal year.

*For FY Mar/2020 and FY Mar/2021, company-owned buildings include the Chubu Office (Nagoya); from FY Mar/2022, the Chubu Office building is excluded due to relocation to a leased building.
