Climate change

We have designated addressing climate change as one of our Materiality and promote activities aimed at achieving carbon neutrality by 2050. In February 2022, we reaffirmed our stance on climate change within and outside the Group by endorsing the TCFD recommendations. Based on the framework of the TCFD recommendations, we also conducted a scenario analysis and summarized the business risks and opportunities arising from climate change and published the TCFD Report in May of the same year.

We conducted a scenario analysis targeting our domestic operations, which account for more than 95% of the Group’s total GHG emissions, and used the results to compile a series of risks and opportunities resulting from climate change. Since the forecasts are highly uncertainand difficult to analyze, we looked at multiple climate scenarios, ranging from 1.5 ºC to 4.0 ºC. We also identified, analyzed, and evaluated risks and opportunities relating to climate change on short-term (up to 2025), medium-term (up to 2030), and long-term (up to 2050) bases. As a response to opportunities that have a significant financial impact in our scenario analysis, we are using the name DOWA Green Action for products and services that contribute to society’s response to climate change, and have set sales targets for fiscal 2030. We believe that expanding these products and services will help reduce risks across society as we move towards a decarbonized society.
As fiscal 2024 is the final year of our Midterm Plan 2024, we plan to update our midterm outlook and review our risks and opportunities.

Starting in the second half of fiscal 2022, we have reaffirmed our situational circumstances regarding the social environment and our business based on the TCFD scenario analysis. Our confirmation has the aim of increasing the specificity of our mid-term measures to address climate change and the accuracy of our forecasts through 2030.

As we identified the various ways that climate change could impact the DOWA Group, we paid particular attention to the automobile market due to the close connection to the Group’s main businesses and the major effect changes could have on the Group’s performance. From the perspective of a value chain, we analyzed changes in the automobile market resulting from the growing shift to electric vehicles (EVs) and identified the opportunities and risks for our business operations as shown below.

We have positioned risk management as one of our Materiality. We strive to enhance risk management by establishing a system to appropriately manage and mitigate various risks arising through our business activities.
Risk management related to climate change is integrated into the Group’s overall risk management.

In recent years, weather disasters such as heavy rain and typhoons have become more severe and frequent, making it increasingly important to prepare for weather disasters. In response to the physical risks of climate change, in fiscal 2023, the DOWA Group conducted a location risk survey on vulnerability to natural disasters at all domestic production bases. We conducted risk assessments covering a wide range of disasters, including floods, inundation, high tides, and landslides, as well as earthquakes, tsunamis, and volcanoes. We held inhouse briefings to share the results of the assessments with the entire company.

After sorting out the risks for each location by event, we are incorporating them into the BCP and disaster prevention plans of each base and taking measures for particularly high-priority disasters and regions.

To achieve carbon neutrality by 2050 and to link our efforts to address climate change to the sustainable growth of the Group, we have set contribution targets through products and services and GHG emissions reduction targets as interim targets for fiscal 2030.
Additionally, in May 2023, we formulated a roadmap for achieving carbon neutrality by 2050. We will make maximum use of existing technologies to reduce GHG emissions and systematically work to introduce new technologies. In addition to energy conservation, renewable energy, fuel conversion, electrification, and other measures, we will actively promote in-house development of biomass fuels, ammonia burners, and other inhouse initiatives. In the future, we will promote climate change countermeasures through multiple options, such as considering the use of negative emission technologies that capture and store CO₂.

The DOWA Group aims to achieve carbon neutrality by 2050.

The Group aims to be carbon-neutral by 2050 and, as a milestone, has set an interim goal of reducing Scope 1 and Scope 2 GHG emissions in Japan compared to fiscal 2013 levels by fiscal 2030, as shown in the table below. These targets are set in accordance with the targets for each category in the Japanese government’s Plan for Global Warming Countermeasures(*), which was formulated to reduce GHG emissions in fiscal 2030 to 46% of the level in fiscal 2013. We are in the process of determining Scope 3 GHG emissions and will consider incorporating them into the target in the future.

Based on the above targets, the Group has set an emissions target of 1,200 thousand tons of CO₂ for fiscal 2030. We will continue to monitor changes in social trends, technological innovation, and other factors and work toward further reductions from a medium- to long-term perspective.
This target does not cover GHG emissions from overseas business sites. However, we will consider setting a target as we proceed with understanding and monitoring the situation in the countries where they are located. The status of GHG emissions reductions will continue to be monitored. Targets may be revised as necessary, considering domestic and international policy trends and socioeconomic conditions toward decarbonization.

The DOWA Group provides a wide range of products and services contributing to society’s efforts to combat climate change. We offer many products and services to contribute to the reduction in GHG emissions through our supply chain, such as silver powder used for solar panels, which is indispensable for renewable energy metal materials for fuel cells and EVs, and the recycling of lithium-ion batteries and solar panels. We also provide society with non-ferrous metals, which are indispensable for the decarbonized society of the future, through our recycling-oriented business model that incorporates sustainable resource recycling processes, including recycling. We have named DOWA Group’s unique contribution DOWA Green Action (DGA) and have set targets for fiscal 2030.

We aim to achieve carbon neutrality by transitioning to a circular economy by reducing our own GHG emissions and providing society with products and services through a low-carbon resource recycling process. In DGA, we identified two target areas: (1) providing materials that contribute to realizing a decarbonized society through resource recycling and (2) products and services that help customers and society cope with climate change. We are currently working on expanding these target areas.

BIODIESEL OKAYAMA CO., LTD. accepts cooking scraps and discarded food from convenience stores, supermarkets, and school lunches, generates methane gas, and uses this gas to generate electricity equivalent to the annual electricity consumption of approximately 1,600 households. Recycling of food that is discarded after the distribution stage has not progressed because it is difficult to separate it from its packaging. However, this facility has installed preprocessing equipment to remove packaging and other waste, and is using food waste that is difficult to recycle as an energy source.

The number of solar (PV) panels has increased rapidly due to the Feed-in-Tariff (FIT) system in recent years. These panels are expected tobe discarded in large quantities from around 2033 when the FIT system ends. DOWA is working to recycle resources by establishing an integrated processing system that covers everything from the collection and transportation of used solar panels to recycling and conversion into smelting raw materials, with the aim of recycling (metal and heat recovery) used PV panels. Current mainstream silicon solar panels use valuable metals such as silver and copper, and some also contain lead. However, DOWA’s scheme allows us to coordinate recycling and waste disposal in-house, allowing us to efficiently manage hazardous substances and recover resources.

Heat treatment, which gives automobile and industrial equipment parts properties such as durability and wear resistance, consumes a large amount of energy. However, our heat treatment furnace Z-TKM aims to save energy by shortening lead times and minimizing fuel use,reducing CO₂ emissions by approximately 40% compared to conventional methods. In addition, by combining ammonia and hydrogen burners,we can operate with almost no CO₂ emissions during the process, contributing to the decarbonization of manufacturing supply chains that includes automobile production.

CFCs, HCFCs, HFCs, and other fluorocarbons used as refrigerants in refrigeration and air conditioning equipment have a substantial greenhouse effect, ranging from several hundred to more than 10,000 times that of CO₂, so proper treatment is essential. We have cooperated with the Ministry of the Environment’s Fluorocarbon Destruction Model Projects and have contributed to the establishment of fluorocarbonrelated legislation and the strengthening of regulations by conducting demonstration tests, etc., in cooperation with national and local governments. Currently, our Group contributes to reducing GHG emissions by more than 1 million tons (CO₂ equivalent) per year, including fluorocarbons recovered and recycled from home appliances and fluorocarbons destroyed by thermal decomposition. In the destruction process, we perform thermal decomposition by waste heat from the incineration of waste materials without inputting new energy, thereby reducing our own GHG emissions in our endeavor to prevent global warming. We are also expanding fluorocarbon treatment in Thailand and other countries, which is expected to contribute to GHG emission reductions of more than 10,000 tons per year (CO₂ equivalent) in a bilateral credit project supported by the Japanese government.

The Group’s greenhouse gas emissions are characterized by the fact that they are primarily of electricity-derived and waste-derived, accounting for about 80% of total emissions. CO₂ emissions are particularly affected by the incineration of waste received from outside sources, which varies depending on the amount and composition of the waste. Since it is difficult to control these factors, we are actively promoting thermal recycling, which uses the heat generated during incineration to generate electricity or produce steam. Furthermore, we are working to utilize and expand natural energy sources such as hydroelectric power and solar power. At our manufacturing bases, we are working to reduce CO₂ emissions by switching to more energy-efficient equipment and reducing energy consumption through appropriate operational management.

We will continue to promote energy conservation by improving processes and reduce greenhouse gas emissions by switching fuel sources and utilizing renewable energy in an effort to achieve the Group’s medium- to long-term goals.

Having started in fiscal 2022, Midterm Plan 2024 is aimed at enhancing our economic and social value simultaneously. For climate change, we have five key measures in accordance with our Climate Change Policy. In terms of business operations, we are committed to climate change initiatives that leverage the characteristics of each of our businesses, such as building a sustainable business model to achieve compatibility between resource recycling and decarbonization, with consideration of the analysis of TCFD-related risks and opportunities.

We are working to combat global warming through the use of in-house power generation from renewable energy sources and the promotion of renewable energy through our business.

In 1897, the Company began operating Japan’s second hydroelectric power plant for mining development. Since then, the Company has continued to expand and upgrade its facilities as its business has grown, and it currently owns six hydroelectric power plants in Akita Prefecture. Making it an important energy source for Kosaka Smelting & Refining Co., Ltd.

We are working to expand the use of renewable energy by installing solar power generation systems at six of our business sites in Japan and overseas. In addition to being used as part of the electricity required for business activities, some electricity was sold back to the grid.

We are working on biomass gas power generation from food waste in Okayama Prefecture.

The Group generates waste heat at six sites, five in Japan and one overseas.Waste heat power generation is a method that uses the heat from incinerating waste materials and exhaust heat from furnaces to produce high-temperature, high-pressure steam that turns turbines to generate electricity. Energy can be generated from waste, leading to the curtailment of fossil fuels.

In April 2022, we set up the DOWA x Tohoku University Co-creation Research Center with the aim of bolstering our research activities with Tohoku University. The exceptional technological seeds at Tohoku University and the technology possessed by DOWA will be further integrated. The goal of this joint project is to create cutting-edge technology that will contribute toward offering resource recycling and excellent materials and technology while also responding to sustainability issues, including carbon neutrality. In the initial phase, from fiscal 2022 to fiscal 2024, we will explore the following themes and aim at launching collaborative research projects.

As part of our response to climate change issues, we promote ”mitigation measures” to reduce greenhouse gas emissions, such as renewable energy and energy saving. In addition, we are also taking action in terms of ”adaptation measures”, such as disaster response and heat stroke countermeasures.

We are a member of the Japan Mining Industry Association (JMA) and participates in the JMA’s specialized committees and subcommittees on climate change. The Japan Mining Industry Association has published “The Non-Ferrous Metals Industry’s Efforts to Achieve Carbon Neutrality by 2050,” and shares information with its member companies and collaborates with them in their efforts to achieve this goal. We regularly confirm that these industry associations are consistent with our approach and direction, and if there is any significant weakness or inconsistency, we will consult internally and with the industry associations and make adjustments so that our climate change strategy and activities with the industry associations are aligned.

DOWA ECO-SYSTEM CO., LTD., the environmental business of the DOWA Group, has been a full member of the Climate Leaders’ Partnership (JCLP) since 2014. JCLP was established in recognition of the need for industry to develop a healthy sense of urgency and take proactive action to achieve a sustainable decarbonized society JCLP is an economic organization unique to Japan. By leading the transition to a decarbonized society, we aim to become a company that is sought after by society.
