Murata and the Environment

Manage chemical substances

Murata's chemical substance management

Looking toward the realization of sustainable social systems, Murata strives to provide products with minimal impact on the global environment.
In addition to complying with laws such as RoHS Directive and the REACH Regulation, we established internal standards based on global trends in environmentally hazardous substances and on requests from our customers. We are also actively promoting initiatives to reduce or prohibit environmentally hazardous substances contained in products, through setting targets and policies as shown in the table below, and through the management system shown in the figure below.

Fiscal 2024 results

⟨Compliance violations related to chemical substances contained in products: 0⟩

  • There were zero compliance violations related to chemical substances contained in products.
  • We continue to conduct in-house training updated based on the latest trends, on the topic of managing chemical substances.

⟨Active reduction of environmentally hazardous substances contained in products⟩

  • We continued to revise internal standards, and in October 2024, finished updating these standards. With regard to substances recommended for elimination during Stockholm Convention POPRC19 and 20, we have finished eliminating or replacing medium-chain chlorinated paraffins (MCCP) through initiatives continued from 2023. Additionally, we have prohibited substances recommended for addition to the PIC list during CRC19 of the Rotterdam Convention before legislation is enacted.
  • We began having discussions on selecting regulated substances and changing internal standards, in preparation for updating these standards in October 2025.
  • We decided to further reduce the amount of lead in products as an voluntary initiative independent of regulations, and are continuing to research alternatives in order to reduce use. We provided intermediate results as of March 2024 to “The Umbrella Project,” a global industry-wide project related to lead in electronic equipment.
  • Set as a target that does not change each fiscal year

Management system

System for designing and evaluating products so that they do not contain environmentally hazardous substances exceeding regulated values (product assessment)

Product
development

System for obtaining material composition information from suppliers so that only certified materials are purchased (green procurement)



Procurement

System for verifying and evaluating manufacturing equipment, etc., so that environmentally hazardous substances do not become attached to products

Manufacturing processes

System for ensuring that products that contain banned substances cannot be shipped to customers that do not approve the shipment of such products


Shipments

We are also responding preemptively to the revision of laws relating to environmentally hazardous substances.
The Stockholm Convention on persistent organic pollutants (POPs) commonly referred to as the POPs Convention, is a framework for international cooperation aimed at reducing or eliminating typical substances of concern. “Dechlorane Plus” was newly added to Annex A (Elimination) at the 11th Conference of the Parties (COP11) held in May 2023. Since the early 2000s, Murata has been focusing on the environmental concerns of fire retardants including chlorine and has voluntarily engaged in restricting its use, and as a result, promptly finished eliminating or replacing “Dechlorane Plus.”

In addition to managing chemical substances contained in our products, Murata manages chemical substances used during the manufacturing process. It is known that portions of components included in chemical substances used in the manufacturing process have detrimental effects on the human body. Since workers are exposed to a high-concentration of chemical substances used for cleaning for long periods of time, there is a concern over possible adverse effects on their health. In response to this situation, Murata has prohibited the use and inclusion of 9 high risk chemical substances used for cleaning from fiscal 2022 to fiscal 2024. In these 3 years, within the range possible with the current level of technology, the use and inclusion of the above 9 substances has ended, and alternative substances have been applied for use. In the future, Murata will continue on with further measures to reduce the risk of exposure of workers to chemical substances.

Management of environmentally polluting substances

At Murata, we record data on the chemical substances we use in our Japan plants in a database, and we use a system that allows us to easily understand and manage the status of use of individual chemical substances.

We use this system for the discharge and transportation calculations required by the Act on Confirmation, etc. of Release Amounts of Specific Chemical Substances in the Environment and Promotion of Improvements to the Management Thereof (PRTR Law).

Of the 515 classes of substances that are subject to reporting under the terms of this law, in its Japan operations between April 1, 2024 and March 31, 2025, Murata used one ton or more of 36 classes of substances including toluene and nickel. The amounts used are shown below.

Green procurement

Murata recognizes that it is crucial to protect and conserve the global environment to achieve sustainable development in the human society, and is working to promote environmental load reduction (E), securing health and safety (H and S), and disaster prevention activities based on the “EHS Disaster Prevention Policy.” The Procurement Department promotes “Green Procurement” where materials with low environmental load are procured, and the understanding and cooperation of suppliers are necessary to achieve this. By clarifying requirements for suppliers through the “Green Procurement Standards” issued in October 2005, Murata aims to establish a long-term relationship with suppliers that agree to these standards.
Specifically, we are promoting “Green procurement” based on the following 5 Steps.

Step 1: Murata Group Environmental Policy Establishment
In order to reduce the environmental load of products, "green procurement" is required to procure materials with a low environmental load.
When beginning businesses with suppliers, Murata distributes the "Green Procurement Standards" that includes details such as Murata's approach to green procurement and requirements for suppliers, and promotes green procurement with the understanding and cooperation of suppliers. The latest version is distributed through our system for suppliers and supplier dedicated portal when revisions are made.

Step 2: Finalizing contracts with suppliers
Once suppliers have understood Murata’s contained-substance standards as outlined in the "Green Procurement Standards", they are required to submit the “Agreement to Environmental Protection Measures.” This is one of the criteria used to determine whether or not to start businesses with new suppliers.

Step 3: CMS audit/evaluation execution
When conducting new business, we ask that our partners also address global environmental problems such as climate change and environmental pollution based on the "Murata Group Supply Chain CSR Procurement Guidelines." Moreover, in addition to asking to verify the certification status of suppliers under environmental management systems (ISO 14001, etc.), we audit the state of chemical substance control at the manufacturing sites to determine whether we can do business with a supplier. Once we begin doing business with a supplier, we periodically evaluate how they are managing chemical substances and working toward reducing their environmental load. Suppliers who receive a poor evaluation are requested to make improvements or receive guidance through on-site audits.

Step 4: Green level investigation execution
Murata implements “Green level investigation” for each item before adopting materials.
As the basis for this process, Murata uses its proprietary technical standard, which stipulates bans and reductions in the use of substances in accordance with legal regulations and customer requirements.
Based on the contained-substance information for materials supplied by our suppliers, our specialist staff review and certify them, and register the certified items in the environmental information database.

Step 5: Establishment of a system that enables ordering of certified materials only (Purchase Order Checking System)
We have introduced a “Purchase Order Checking System” that enables ordering of only materials registered in the environment information database and established a system to ensure that only certified materials are brought into Murata’s facilities.
