Acquiring land, building plants and recruiting people to work there. Procuring raw materials and utilizing technologies to create products with added value products which are delivered to customers in the electronics or automotive industries or manufacturers of different materials, who add new value, all of this then culminating in the delivery of final products to the market. This has long been the business flow of Mitsui Kinzoku Group. It is the business of manufacturing. Our work processes involve many environmental risks. We are constantly striving to monitor each of these risks and to minimize their impact as much as possible. It is in this Environment domain more than in any other that we are required to work on through both of our business and CSR activities. MITSUI KINZOKU 62 CSR REPORT 2017 Flitting Fireflies in Kanagawa, Japan. June 2017 MITSUI KINZOKU 63 CSR REPORT 2017 Environmental Management Reduce environmental footprint We are striving to conserve the global environment while producing useful materials that will contribute to sustainable development in society. Continuing to achieve such a balance is one of the important management issues of Mitsui Kinzoku Group. Conserve the environment and continue our business Smelting non ferrous metals from mineral ore and supplying useful materials for various industries and society. This is the origin of our business. However, developing mines and mining have an impact on the environment. Even in the process of refining and processing ore, we consume energy and water. We also inevitably create by products, CO2 and waste. In 2001, we established the Basic Policy on Environmental Conservation and formulated the Environmental Action Plan aiming to improve our environmental management system and minimize the environmental impact. President Chief Environmental and Safety Officer Supreme Safety and Environmental Meeting Environmental and Safety Supervisory Manager (General Manager of the Environmental and Safety Dept.) Environmental management Chief Environmental and Safety Administrator (Senior Executive Officer of the sector) (Business Sectors) Mitsui Kinzoku Group has established the Supreme Safety & Environmental Meeting as a place to deliberate and determine the most important matters related to safety and the environment. Guidelines and action plans determined at the Meeting are spread to the business locations of the Group by the Environmental and Safety Supervisory Manager(General manager of the Environmental and Safety Dept.) under the direction of the Chief Environmental and Safety Officer. At each business location, the Head will execute the action plans as the Chief Environmental and Safety Administrator. Chief Environmental and Safety Administrator (Head of site) Chief Environmental and Safety Administrator (Head of site) Environmental Management System Chief Environmental and Safety Administrator (Head of site) (Production bases and Group Companies) Basic Policy on Environmental Conservation Principle Positioning the conservation of the global environment as one of the most important management issues, we will act with consideration for environmental conservation in all aspects of our business activities. Policies 1. We will make efforts to prevent environmental contamination and reduce environmental burden by complying with environment-related laws and regulations and setting necessary self-standards. 2. We will improve the organization and system to promote the environmental preservation activities at each location and company of the Mitsui Kinzoku Group. 3. We will strive to prevent global warming and reduce wastes and the emission of environmental pollutants by setting targets. 4. We will actively promote the development of environmentally-friendly technologies, materials, and products. 5. We will continuously improve the environmental management system by regularly implementing an audit. 6. We will increase the awareness of environmental preservation by reminding all people working for the Mitsui Kinzoku Group of its importance through education and information, etc. about the environment. These policies apply to all the directors, officers and employees of Mitsui Kinzoku and its Group companies. MITSUI KINZOKU 64 CSR REPORT 2017 Environmental audits We conduct an environmental audit at all 45 business locations in Japan. We conduct it annually at mines and business locations with a high environmental risk that engage in smelting, once every two years at business locations with a moderate environmental risk among those that engage in the processing of parts, and once every three years at business locations with a low environmental risk. In 2016, we carried out an audit at a total of 23 business locations. In an environmental audit, usually two or more auditors spend half a day to two days at one business location and conduct the audit according to ISO The auditors collect performance data such as measured values of waste water and waste gases, etc., checking on site risks, and also check responses to matters pointed out in the previous audit. The business locations complete the remedial measures for the matters pointed out in the audit within the relevant fiscal year. In June 2015, we added the audit of statutory applications and notifications. We check whether applications required by laws and regulations are appropriately made. Environmental training Mitsui Kinzoku Group believes that increasing the environmental awareness of individual employees will help encourage environmental activities. We, therefore, provide lectures to encourage compliance with environmental laws and regulations. We implement workshops about environment relatedlawsandregulationsasgrouptraining for employees of all group companies, gathering at our headquarters. We are also focusing on environmental training that is helpful at the workplace. For example, we give lectures to site managers at each site about the laws and regulations required for their own operations. We provide training in relation to actual operations.

MITSUI KINZOKU 66 CSR REPORT 2017 Overall environmental adverse impacts in the smelting business ( ) In fiscal 2016, Mitsui Kinzoku Group emitted 1,338,000 tons of CO2 from fuel combustion through its business in Japan, of which the smelting business makes up more than 70%. Accordingly, we have compiled raw materials and energy (input) as well as products and emissions (output) in the smelting business. The smelting business requires massive electricity. The Group works to contribute to resource recycling society by reducing its energy consumption and promoting recycle smelting. ( ) The scope covers four manufacturing sites: Hachinohe Smelting Co., Ltd., Kamioka Mining and Smelting Co., Ltd., Hikoshima Smelting Co., Ltd., and Takehara Refinery. We have started to gather environment related information on businesses other than the smelting business, including overseas sites.

In fiscal 2016, the use of recycled raw materials exceeded its use of natural resources such as ore. In Japan, recycled materials account for 42.3% of the raw materials used in smelting and materials segment and 51.9% of the raw materials used in other business segments. The share for our group, as a whole, including overseas affiliates, is 37.9%. Used products that have become waste, by-products of another company, etc. Recycled raw materials 43.0% 567,723 t Fiscal ,320 thousand tons Unused natural products such as ore Primary raw materials 41.0% 540,922 t Unused products, parts, etc. manufactured or processed by another company Secondary raw materials 16.1% 212,122 t MITSUI KINZOKU 67 CSR REPORT 2017 Investment and expenses Every year we invest in environmental conservation activities and we are steadily reducing our environmental impact. We make efficient environmental investments, taking into account their cost effectiveness. Environmental expenses in fiscal 2016 were 4,230 million yen, a decrease of 2.1% year on year. Environmental investments totaled 5,270 million yen, an increase of 48.0% year on year. Large investments in fiscal 2016 included expansion of wastewater processing capacity at Hachinohe Smelting and expansion of waste gas processing capacity at Takehara Refinery and Kamioka Mining and Smelting. We make environment related investments at a total of 29 business locations in Japan, mainly at business locations related to the smelting business. Others (Labor cost, office commodity expenses, etc.) 47.5% Fiscal million yen 16.2% Waste treatment outsourcing expenses 26.0% Energy expenses 10.4% Maintenance and repair expenses Break down of environmental management expenses Trends in environment-related capital expenditures and environmental management expenses (Hundred million yen) Environment-related capital expenditures Environmental management expenses (*1) Main capital expenditures (FY 2016) Hachinohe Smelting Co., Ltd. Improvement of waste water treatment facilities Takehara Refinery New construction of waste gas treatment facilities Kamioka Mining and Smelting Co., Ltd. New construction of fuel gas treatment facilities (*1) The figures are different from those in last year s report because some smelters changed the classification of environmental management expenses Fiscal Reduce waste We are constantly working to reduce waste through efforts to develop the process of reuse and recycle wastes in such a way as crushing waste flexible containers for use as a heat source. In the Environmental Action Plan formulated in 2001, we set a target waste generation rate (the amount of waste generation excluding waste to be reused and recycled/net sales) at each business location. In fiscal 2016, the amount of waste generation rose by 12.0 tons from the previous fiscal year due to an increase in the amount of production Fiscal Trends in the amount of waste generation (Thousand tons/year) MITSUI KINZOKU 68 CSR REPORT 2017 Reduce emissions of chemical substances Each manufacturing site of the Group files the release and the transfer amount of chemical substances to the government under the Act on Confirmation, etc. of Release Amounts of Specific Chemical Substances in the Environment and Promotion of Improvements to the Management Thereof (Law concerning Pollutant Release and Transfer Register [PRTR]). The release of the top six substances, such as lead compounds, arsenic, and inorganic compounds thereof amount to 97.9% of the total released in fiscal The management of hazardous chemical substances contained in products has become an essential requirement. We also respond to the guidelines for chemical substances contained in products, such as the RoHS Directive and the REACH regulations required by customers. Mitsui Kinzoku Group continuously strives to collect and replace chemical substances that may cause environmental pollution. Thus we focus to reduce or remove use of such chemical substances from our products. 2,500 2,000 1,500 1, , ,169 2, Released 1, Transferred 1, Volume of chemical substances released and transferred (tons/year) Fiscal Prevent air pollution and water pollution Every manufacturing site of Mitsui Kinzoku Group monitors the following in accordance with laws, regulations and ordinances and voluntary standards. Sulfur oxide (SOx) emissions produced on the combustion of fossil fuels containing sulfur, nitrogen oxide (NOx) emissions from boilers, incinerators and other combustion equipment, and particulate matter, as well as water quality including BOD and COD which indicate the level of organic material in wastewater. Starting from this fiscal year, we are gathering the monitoring results of each business site across the entire Group. * The accuracy of figures for some overseas business sites cannot be fully verified and are therefore omitted from this report.

We also set a group wide reduction target of carbon footprint. Reduce CO2 emissions Mitsui Kinzoku Group has set a reduction target for the energy consumption rate (crude oil equivalent energy consumption/net sales). We are executing a specific reduction plan. The crude oil equivalent energy used by the overall Group has declined since its peak in fiscal In fiscal 2016, however, the smelting and materials segment increased the energy volume by 2.9% year on year, to 360,200 kiloliters per year, and the Group as a whole increased it by 3.0%, to 495,600 kiloliters per year. In fiscal 2016, CO2 emissions from fuel combustion of Mitsui Kinzoku Group as a whole rose by 8.4% year on year, to 1,338,000 tons per year. The CO2 emissions from fuel combustion increased by 16.3% from fiscal 1990, the base year of the Kyoto Protocol, due to the production expansion at the
