We recognize that climate change is an urgent issue for society as well as a management issue for Neturen.We aim to achieve virtually zero CO2 emissions by FY2050, and in our 15th Mid-Term Management Plan, we set a goal of strengthening our efforts to address climate change and established a cross-company committee.We will work to grasp the current situation and promote specific initiatives in the future.
In its 15th Mid-Term Management Plan, Neturen has set the goal of “promoting CO2 reduction and contributing to the creation of a sustainable society.”Recognizing climate change as a management issue, we established a committee dedicated to CO2 emissions reduction in April 2021 and a company-wide Environmental Conservation Committee in April 2022 to strengthen our efforts to promote climate change initiatives.The meeting is held once every three months, with directors and executive officers serving as committee members.The Company-wide Environmental Preservation Committee has established four cross-departmental subcommittees specializing in CO2 emissions reduction.The Equipment Division is responsible for the study and development of facilities that reduce CO2 emissions, and plans to introduce solar power generation systems at the Amagasaki and Kobe plants in FY2022.In the Manufacturing Division, we plan to upgrade to energy-efficient and high-efficiency equipment at our plants and develop high-efficiency equipment for our own products.In the Procurement Division, we are considering the purchase of energy from renewable sources and working to grasp Scope 3 (CO2 emissions in the supply chain), while at the same time taking steps to reduce CO2 emissions during transportation.In the Sales Division, we are in the process of calculating the extent to which out products contribute to reducing CO2.From now on, each department will proceed with specific initiatives after identifying the current situation.

Neturen, whose mainstay business is induction heating (W-Eco) technology, which is pollution-free and resource-saving, focuses on reducing CO2 emissions through "energy conservation," and each plant and office is taking the lead in promoting measures to cope with climate change.
More than 91% of energy use at each of Neturen's business sites is from purchased electricity.Due to the nature of the business, which uses a large amount of electricity, the factory implements measures that lead to energy conservation from all perspectives in its mid- to long-term plans.In FY2021, the intensity of energy use was 96.7% of the previous year's level, achieving the target of 1% improvement.On the other hand, the five-year average of the change in intensity was 100.7%, falling short of the target.Neturen also delivers high-strength steel products for civil engineering and construction throughout Japan, and is designated as a specified shipper (30 million ton-kilometers/year or more).Trucking accounts for about 95% of the environmental impact of logistics.Through cross-organizational implementation of measures such as improved loading rates, joint transportation (mixed loading of multiple suppliers), and use of relay warehouses, in FY2021, the intensity from transportation energy use was 99.8% of the previous year's level, and the target of 1% improvement was not achieved.The five-year average of the change in intensity was 102.4%, which means that the target was not achieved.In FY2022, we will strengthen energy-saving activities and logistics improvements, aiming for a 1% reduction in intensity compared to the previous year.

Environmental education is scheduled to take place inside the company to promote understanding and penetration of climate change countermeasures.A preliminary briefing held in April 2022 was attended by approximately 70 people, two from each plant in the Manufacturing Division.We will hold study sessions in cooperation with the energy conservation committees of each plant in the future.
In FY2022, education will be provided on the environment at rank-specific training sessions (for a total of 71 leaders, assistant section chief, and newly appointed managers).
Sustainable development of corporate activities and society can only be achieved if the global environment is healthy.Based on the Basic CSR Policy, Neturen recognizes environmental protection as its social mission and will strive to reduce CO2 emissions, conserve resources, and prevent pollution, while pursuing the development of new technologies and products that reduce environmental impact, in order to live in harmony with the global environment.
To systematically address environmental conservation, we have established a company-wide Environmental Conservation Committee chaired by the director in charge of environmental affairs.The company-wide Environmental Conservation Committee has organized advisory committees, the Energy Conservation Committee and the Logistics Improvement Committee, to promote energy conservation activities and logistics improvements.For activities at each business site, a Business Site Environmental Preservation Committee, led by a member of the Environmental Preservation Committee, has been established to promote environmental conservation activities at each business site.
We have also acquired ISO 14001 certification, the international standard for environmental management systems, and are actively promoting the reduction of the environmental impact of our products and services.We are also expanding the scope of our environmental activities by promoting the acquisition of certification to the same standard by our Group companies in Japan, and we are promoting the acquisition of certification at all of our plants.

*Total material input and total production volume include contracted processed products.
*The amount of chemical substance emissions and transfers was calculated only for substances handled in quantities of 1 ton or more for Class I designated chemical substances and 0.5 tons or more for specified Class I designated chemical substances.
*For those sites that do not measure wastewater discharge, the amount of water resource input was used as the wastewater discharge.

We are helping to create a recycling-oriented society and promote efforts to reduce waste, recycle, and prevent environmental pollution by conserving limited resources.Neturen's basic policy is to promote waste reduction and recycling by ensuring that waste is carefully sorted and properly disposed of by collection and disposal companies.We have established rules for industrial waste management and waste sorting and collection management standards, and each plant and business site is working to implement these rules.The main uses of water at Neturen's plants and offices are to cool steel materials and manufacturing equipment during heat treatment and to clean the surface of steel materials.Various measures are being implemented so as to use water resources effectively.Mainly, water used for cooling and other purposes is circulated to reduce the amount of groundwater pumped and industrial water consumed.
Furthermore, in the high-frequency quenching process, a quenching fluid mixed with a cooling agent is used to prevent quenching cracks caused by rapid cooling.Since this cooling agent is used in a closed system, there is no contamination of soil. However, to prepare for the event of a cooling water leak, we have documented emergency response procedures and conduct prescribed training once a year to prevent soil contamination and contamination of public waters.
Neturen aggregates and manages the amount of chemical substances used, emitted, and transferred during product production at each of its plants.Although we are not subject to the PRTR system because the amount of chemical substances handled is less than the default amount, we aim to minimize the risk of damaging the global environment and harming human health and manufacture products that are friendly to humans and the earth by conducting appropriate management regardless of the amount of chemicals used.
We have developed a high-frequency power supply device using a "SiC-MOSFET" (SiC elements) large-capacity power semiconductor and an FPGA digital board.High-frequency power supply units are incorporated into induction heating equipment for quenching and tempering automotive parts and construction machinery parts, etc. They convert commercial-frequency power into high-frequency power and supply it to induction heating coils.
This device uses "Si-MOSFETs" (SiC elements), which are SiC elements with higher withstand voltage than the conventional power semiconductors, and by increasing the power supply voltage, the components and losses have been reduced, resulting in a smaller and lighter devices (20% smaller in volume and 30% lighter in mass than conventional devices).Furthermore, the SiC element's features of high-speed on/off operation and low on-resistance reduce the loss of the element itself, and the overall efficiency of the power supply can be expected to increase by 5% compared to SiC power supplies, and by approximately 30% compared to vacuum-tube power supplies.
We help to realize a sustainable society with IH technology that saves space and energy and is environmentally friendly.
