Environment

Murata continues efforts to reduce the environmental impact in manufacturing. “Creating a decarbonized society” has been selected as a priority issue (materiality), greenhouse gas (GHG^*1) reduction target amount has been set and business is being operated under that target.

Total GHG emissions increased rapidly until fiscal 2018, due to increased production spurred by higher demand for electronic components in recent years, M&As, and new business expansion. However, with the enactment of the Paris Agreement, companies are now required to reduce their total GHG emissions regardless of business expansion.
To achieve this goal, continuous energy-saving activities and sourcing of renewable energy are essential. Murata supports the Paris Agreement, Japan’s Nationally Determined Contribution (NDC), and climate change-related legislation (such as the Act on the Rational Use of Energy and the Act on Promotion of Global Warming Countermeasures). Murata implements initiatives consistent with them and has pioneered effective measures within the industry, including declaring its commitment to RE100.

At the same time, the world is being frequented by large-scale natural disasters associated with climate change, and further initiatives must be implemented to reduce GHG emissions. Murata believes that it will be crucial to pursue non-continuous energy saving and increase the use of renewable energy with additionality^*2 while expanding the insights gained from such activities not only within the company but also throughout the entire supply chain (from procurement to production, inventory management, logistics, and sales). As the Global No. 1 Component & Module Supplier, it is Murata's duty to strengthen collaboration with like-minded stakeholders and accelerate initiatives aimed at realizing a decarbonized society all over the world.

Murata is dedicated to understanding the latest trends related to climate change through its participation in global alliances and industry associations. In line with its commitment to the Paris Agreement, Murata periodically reviews its alignment with the missions of the associations it participates in, ensuring consistency with Murata’s own goals and business activities. If maintaining conformity with their missions becomes difficult, Murata will consider withdrawal.

In December 2020, Murata joined “RE100,” an international initiative which aims to switch the power used in business activities to 100% renewable energy. In fiscal 2024, Murata decided to bring forward the achievement of the RE100 target by 15 years, from the original fiscal 2050 to fiscal 2035. Through the pursuit of this target, we will accelerate the realization of a decarbonized society, contributing to the creation of a sustainable society.
In recognition of these initiatives, Murata received the “RE100 enterprising leader” award at the RE100 Leadership Awards 2025, hosted by RE100.

Because multilayer ceramic capacitors (MLCCs) and other electronic components which are our main products require that a high temperature state be maintained in the calcination process, they use a considerable amount of power. Due to the space restrictions on the number of units that can be calcinated at one time, we are promoting initiatives to make MLCCs lighter, thinner, shorter and smaller to reduce the environmental load (use of power and raw materials) during calcination.

In addition to reducing the environmental load in such production processes, we aim to promote the use of renewable energy at production subsidiaries in Japan and overseas. We have already installed solar panels at 29 group sites. Recently, we are promoting the installation of efinnos, our solution system that maximizes the use of generated power by combining solar panels with storage batteries. We will continue making necessary investments in 2026 and onwards.

RE100 is led by The Climate Group in partnership with CDP, as part of the We Mean Business coalition. Since April 2017, Japan Climate Leaders’ Partnership (JCLP) has been the Climate Group’s Regional Delivery Partner on RE100 initiative in Japan.

Murata is a member of the Japan Electronics and Information Technology Industries Association (JEITA). The four electric and electronic organizations including JEITA are targeting an average annual improvement of 1% in the energy consumption rate for fiscal 2030. In addition, they have also set a challenge target of reducing GHG emissions from the activities of Japanese companies by about 46% versus 2013 by fiscal 2030. In order to achieve this target, Murata is also working to improve energy efficiency through energy-efficiency measures at factories and offices, etc. As a Liaison Group of Japanese Electrical and Electronics Industries for Global Warming Prevention collaborating with relevant organizations, JEITA promotes carbon neutrality action plans in the electric and electronic industry. Drawing on domestic and international networks, JEITA presents opinions to international initiatives, including the revision of GHG Protocol, and is actively involved with submitting opinions to public comment solicitation regarding the Basic Energy Plan and the NDC. As an enterprise participating in carbon neutrality action plans, Murata is providing successful examples, cases of contributing to GHG reduction, and energy-saving case studies with an aim to share information on these efforts.

Murata has long been involved in implementing energy saving initiatives, planning and implementing approximately 500 new energy saving measures annually. Due to these initiatives, we were able to slow down an increase in energy consumption that naturally occurs in association with business expansion, achieving a reduction of approximately 40 to 50 kt of CO₂ equivalent. However, recent business expansion has outpaced these efforts, and total GHG emissions have increased in recent years.

In response, Murata has implemented measures to save energy and further our utilization of renewable energy, allowing for a drop in GHG emissions from their peak in fiscal 2018.
Total GHG emissions in FY2025 came to 938 kt-CO₂e^*1, achieving a reduction of 106 kt-CO₂e^*1 compared to the previous year. In addition to the early achievement of the RE100 goal, Murata set new carbon neutrality goals: an in-house net zero GHG emissions goal for fiscal 2040 and a net zero GHG emissions goal for fiscal 2050 for the entire supply chain.
To achieve these targets, we will further accelerate our initiatives.

In order to accumulate future GHG reductions, we designed an internal carbon pricing system and began putting it into operation in fiscal 2021. Specifically, we are assigning a monetary value to GHG reduction and embedding it into the investment index to introduce shadow pricing, which encourages decision-making that executes investments that are effective at reducing GHG. We will continue to implement systems that can even more effectively help to reduce GHG.

As one initiative aimed at “Create a decarbonized society,” at Murata we are striving to expand the amount of renewable energy within the power consumption resulting from business activities. We are focusing not only on actively introducing renewable energy at our domestic and international business sites but also on procuring renewable energy and environmental attributes from off-site sources. Thanks to on-site solar power generation equipment, renewable electricity supply contracts, C-PPA^*1, and renewable energy certificates, we recorded a renewable energy rate of 45.9%^*2 in FY2025, which contributed to an approximate 590 kt-CO₂^*2 reduction in GHG emissions. As of the end of fiscal 2025, we achieved 100% renewable energy use at four sites in Japan and two overseas sites.
We will continue to review renewable energy sourcing in Japan and overseas to reduce our environmental impact.

Renewable energy sourcing at Murata sites

In FY2021, Kanazu Murata Manufacturing (Awara, Fukui Prefecture) became the first plant in the Murata Group to run on 100% renewable energy. This was made possible by introducing a system that combines solar panels, storage batteries, and an energy management system, along with a renewable electricity supply option sourced from hydropower. This plant uses efinnos, the Integrated Renewable Energy Control Solution, to maximize renewable energy use.
Additionally, efinnos received the “Decarbonization Management Award” at the “Decarbonization Solution Pitch 2025,” hosted by the Japan Climate Leaders’ Partnership (JCLP). The award recognized our work toward achieving 100% renewable energy for our own operations — using optimal control of power demand and generation to both increase the renewable energy rate and reduce costs — as well as our development of this operations-driven initiative into a solution that can be deployed at other companies.

Construction of the Murata Group’s first multistory parking garage with a green design at Wuxi Murata Electronics Co., Ltd. (Xinwu District, Wuxi City, Jiangsu Province, China) has been completed. The use of double-sided solar panels and the installation of solar panels on the walls of this parking garage increased the solar energy to ground surface area absorption rate by 1.2 times. This allows for the generation of power equivalent to the annual energy consumption of at least 300 average households and a 490 t-CO₂ reduction in GHG emissions.

Murata will continue to promote renewable energy sourcing at Murata sites in Japan and abroad.

Murata is actively procuring renewable energy from outside sources.
Murata aims to achieve long-term, stable procurement of renewable energy with additionality while also providing a menu of renewable energy power from the grid. With a view to procure renewable energy for approximately half the power required for areas where major sites concentrate, we have signed a P-PPA^*1 with grid power companies (Chugoku Electric Power Co., Inc. and Hokuriku Electric Power Company) and commenced procurement.

We have also entered into a V-PPA^*2 covering solar power generation with Mitsubishi Corporation and Renova, and by procuring non-FIT NFCs derived from a solar power plant expected to generate approximately 200 GWh annually, we are advancing the deployment of renewable energy with additionality that contributes to meeting Japan’s carbon neutrality goal.
Furthermore, in 2026, we also entered into a V-PPA covering wind power generation with Cosmo Eco Power. Under this contract, we procure the environmental value derived from wind power in the form of NFCs, and we anticipate an annual reduction in GHG emissions of approximately 13,700 tons.
Through these initiatives, we are expanding our renewable energy procurement portfolio combining solar and wind P-PPAs and V-PPAs, working to secure renewable energy on a long-term, stable basis while reducing environmental impact.

We will continue to review renewable energy sourcing in Japan and overseas to reduce our environmental impact.

Murata has been continuously implementing energy saving initiatives from the past and continuously executes between 450 and 600 large and small energy saving measures annually (equivalent to 40 to 50 kt-CO₂ reduction).
Since 2015, we have been performing energy audits (energy saving diagnosis) at each group site as well as creating and deploying approximately 200 energy saving checklists which can be horizontally deployed from among energy saving initiatives concerning utilities and production facilities. The progress status, verification of the impact, and updating of the checklists are performed under guidance from the headquarters. In FY2025, we implemented 1,140 energy-saving measures^*2 and achieved results equivalent to a 120 kt-CO₂^*2 reduction in GHG emissions.

Murata also proposes energy-saving solutions using in-house products.
At Ogaki Murata Manufacturing (Ogaki, Gifu Prefecture), we introduced m-FLIP™, an operating rate improvement solution for manufacturing, to visualize equipment status and production volumes, achieving a 20% boost in equipment utilization within four months.
At Minato MIRAI Innovation Center, wireless sensors developed by Murata are being used as part of IoT for equipment maintenance inside the center building. Facility status is visualized by collecting and managing data, such as temperature and humidity conditions and current values of various systems, on the cloud. The utilization of data acquired by sensors and the application of IoT tools to troubleshooting analyses have achieved a 25% energy-saving effect in air-conditioning and a 50% energy-saving effect in patrolling.

Applying material design techniques for ceramic capacitors, Murata also developed the world’s first heat-resistant ceramic catalyst material for exhaust treatment. By adopting catalysts using this material to reduce the consumption of fossil fuel during exhaust treatment, users can reduce GHG emissions deriving from fuel while maintaining exhaust gas decomposition performance.
Wuxi Murata Electronics Co., Ltd. (Jiangsu Province, China) introduced this ceramic catalyst in May 2021 and achieved a 37% reduction in annual fuel consumption (equivalent to a reduction of 400 t-CO₂) while maintaining exhaust gas decomposition performance.

We will continue to focus on the development of technologies and products that bolster the resolution of environmental issues, as well as promote environmental management by actively applying the solutions in-house, thereby contributing to the realization of a sustainable society.

At Murata, we are developing electronic component manufacturing equipment that has a high rate of energy efficiency. Our indicator for the energy savings realized by this manufacturing equipment is energy consumption per unit of production (per unit of net production). We are developing the new equipment with the goal of a 25% or higher reduction in energy consumption against benchmark machinery (conventional manufacturing equipment).
We are also promoting energy-saving improvements in existing manufacturing equipment operating at factories and horizontally deploying our energy-saving measures for production systems.
In addition, every year we conduct energy-saving training workshops for production equipment design engineers in their second year of employment, providing them with expertise in relation to the design of production equipment in order to realize energy savings.
We are also reviewing energy-saving measures for promoting efficient energy consumption, targeting high-energy consumption processes that were identified through visualizing our manufacturing processes.
These efforts reduce the energy required for product manufacturing, thereby achieving highly energy-efficient production.
We will aim to further accelerate our energy-saving efforts through more detailed visualization of energy and energy-saving diagnostics at Murata offices based on our horizontal deployment list for energy saving.

Murata implements energy saving measures not only in manufacturing equipment but also engages in product manufacturing which considers the environmental load across the entire product lifecycle consisting of component material purchasing, design and development, production, usage, recycling, and disposal.

80% of all of Murata's GHG emissions are Scope 3 emissions. We realize that reducing Scope 3 GHGs is just as essential as reducing Scope 1 and Scope 2 GHGs and established Scope 3 reduction goals in accordance with SBT criteria.
Going forward, a wide range of related departments will work together to promote climate change countermeasures across the entire Murata supply chain.

Category 1 (purchased goods and services) accounts for over half of Murata’s Scope 3 GHG emissions. For this reason, we consider it essential to have the cooperation of suppliers to promote our efforts for reducing GHG emissions.
In fiscal 2025, Murata held an initiative policy briefing session for suppliers in Japan, in which more than 230 companies^*1 participated. In this briefing session, we shared the need for decarbonization, referring to the active shift to decarbonization and increasing demand for low-GHG emission electronic components, as well as introduced our own initiatives and specific steps toward reducing emissions.
We also gave one-on-one interviews, during which we asked about the company’s progress in emission-reduction goal setting and request for support while also making a request for their submission of primary data. As a result, we were able to increase the primary data percentage of Category 1 GHG emissions up to 28.9%^*1. As our support for suppliers in reducing emissions, we will continue to collaborate by making proposals that involve our proven renewable energy system and energy-saving system, as well as an energy management system using Murata’s sensors.

We strive to reduce environmental burden at the distribution stage of products in addition to manufacturing stages.
In addition to reducing GHG emissions through simplified lighter packaging and the promotion of modal shift, we are also promoting eco-friendly distribution based on the 3Rs.

In FY2025, we worked to improve the accuracy of aggregation of GHG emissions across all Murata logistics, including overseas logistics. Members of logistics departments including those at overseas sites also held discussions on reduction measures, reaffirming the importance of reducing GHG emissions globally and deliberating future reduction measures.
In domestic transport and delivery, we achieved a 30 t/year cut in GHG emissions from our logistics through delivery in collaboration with companies that share our commitment to reducing environmental impacts.
Going forward, we will promote and expand modal shifts including the use of shipping for cross-border transport and delivery.

In FY2026, we will promote the horizontal deployment of low-profile, lightweight pallets to our overseas sites and will explore reductions achieved through collaboration with other companies, including in procurement and logistics, advancing reduction efforts both within Murata and with external partners. We will also consider using company-wide standard tools to improve data governance going forward.

• In FY2025, our GHG emissions from domestic logistics were 385 tons per month^*1.
• Murata’s GHG emissions during distribution for the entire world were approximately 9,511 tons per month^*1.
