Basic Policy

Our basic policy is to comply with the laws and regulations of each country in which we operate and to conduct procurement activities in the global markets for all necessary materials and services at an appropriate quality, price, and with delivery schedule based on fair business relationships. In order to tackle social issues such as the environment, human rights and labor, we strive to strengthen our supply chain to be sustainable and ethical to increase our customers’, business partners’, and our own corporate value.

Promotion System

We established the Procurement Division as a global organization that promotes sustainable procurement activities, which reports directly to the CFO. In collaboration with the Business and Production Units, we are working towards optimal procurement activities and the promotion of sustainable, global procurement.

Mid-Term Target for the Supply Chain

In order to realize a sustainable supply chain, we establish a mid-term target as well as a yearly KPI for undertaking initiatives.

Mid-Term Target (2025 - 2028)

1. Obtain a risk evaluation score* below Medium in all key suppliers
2. Procure minerals only from RMI-certified smelters following the RMI certification process
   *risk evaluation by RBA-SAQ

We carefully select key suppliers based on (1) transaction amount, (2) replaceability, and (3) characteristics of produced products.

Annual Targets

Educating Procurement Personnel

As part of promoting corporate ethics within the Procurement Division, we conduct various compliance education on topics such as the Renesas Code of Conduct as well for new employees and employees transferring into the team. We also conduct regular education and training for the most recent CSR issues, such as the environment, in order to penetrate and share information inside the team.

Promoting Sustainable Procurement through Fair and Equitable Transactions

Renesas recognizes that, in order to deliver high-quality products and services to its customers through sustainable procurement activities, it is essential to promote sustainability by considering not only quality, cost, and delivery, but also environmental and social aspects.

Based on this, Renesas established the “Renesas Supplier Code of Conduct” in alignment with the Responsible Business Alliance (RBA) Code of Conduct. Together with our suppliers, we promote appropriate practices in areas such as labor, human rights, health and safety, environmental protection, and business ethics. This Code of Conduct is intended to apply not only to direct (Tier 1) suppliers but also throughout the entire supply chain, with the aim of achieving responsible procurement based on shared values.

In 2024, following the revision of the RBA Code of Conduct, we also reviewed and updated the Renesas Supplier Code of Conduct. As part of this update, we have obtained re-acknowledgment of the revised Code from both existing and new suppliers.

Furthermore, agreement to the Renesas Supplier Code of Conduct is a mandatory requirement for onboarding new suppliers, helping to mitigate ESG-related risks within the supply chain. We promote continuous improvement through ongoing dialogue with suppliers, implementation of self-assessment questionnaires (SAQs), and audits as necessary.

We have received agreements and endorsement from many of our suppliers on the initiatives listed in the Renesas Supplier Code of Conduct.

Understanding Risks within the Supply Chain

At Renesas, we regularly conduct Environmental, Social, and Governance (ESG) surveys among our direct material suppliers to check and evaluate the status of their ESG activities. The ESG survey topics include labor, health and safety, environmental, ethics, and management systems. We disclose the assessment results to suppliers and use them as a tool for improvement internally.

In addition, we regularly check the geopolitical and sectoral risks of all material suppliers using a risk assessment platform provided by the RBA.

As a result of these activities, if a supplier is classified as potentially high risk, we promptly ask them to conduct self-tests and self-improvements using a self-diagnosis survey, similarly to key suppliers.

Activity Results

In 2021, we distributed a simplified Self-Assessment Questionnaire (SAQ) to all suppliers, following the revision of the Renesas Supplier Code of Conduct. 878 companies responded.

Since 2022, we have been conducting SAQs for newly onboarded suppliers. In 2025, we received SAQ answers from 965 suppliers.

Promotion of Green Procurement

Based on Environmental Policies, Renesas is contributing to realize a sustainable society by providing environmentally friendly products and solutions. To realize such a society, it is crucial to reduce the environmental impacts of the parts and materials used within the products. At Renesas, we promote “Green Procurement” where we preferentially procure environmentally conscious parts and materials from companies that are proactive in environmental conservation.

We ask all suppliers that provide parts and materials used as components of our products, suppliers that provide parts and materials used in our products, suppliers that provide parts and products used in the packaging of our products as well as suppliers that deliver our out-sourced products to comply with the Renesas Electronics Green Procurement Standards by clarifying the green procurement standards and stating the aims of the guideline which is to reduce the environmental impact of Renesas products.

Through compliance with Environmental RoHS Directives and conducting surveys of the substances contained in purchased products at Renesas, we are able to confirm that each supplier is making progress in environmental initiatives. In addition, for procuring raw materials used in products, we preferentially purchase from suppliers who actively promote environmental protection, whose products have less environmental impact and contain no hazardous substances. We also actively and preferentially select environmentally conscious products in the procurement of goods such as business goods and IT equipment, based on the information on the environmental impact of those goods. 

We require our suppliers, including the direct material suppliers, foundries, and OSAT, to obtain ISO 14001.

Responsible Minerals Sourcing

Responsible Minerals Procurement Policy

In order not to contribute to human rights violation and the destruction of environment within the supply chain, Renesas is working to realize responsible mineral procurement with the aim of procuring materials that does not include conflict minerals, from OECD conflict-affected and high-risk areas, including DRC and adjoining countries, in relations to risks listed on the Annex II of OECD’s guidelines.

picture_as_pdf Responsible Minerals Procurement Policy

Initiative Framework

Step 1: Establishment of Management System

In 2021, we revised the “Supply-Chain CSR Deployment Guidebook” as the “Renesas Supplier Code of Conduct”, based on the RBA code of conduct, and we ask customers to comply with this code of conduct. In addition, internal departments within Renesas work together to establish a structure to identify and evaluate risks.

Step 2: Identifying and Evaluating Risks within the Supply Chain

We work to realize responsible mineral procurement throughout the supply chain by conducting investigations of suppliers to identify smelters using the industrial standard RMI process and disclosing the results to our customers.

Step 3: Establishing and Executing Strategies Against Identified Risks

As a result of investigation, if an uncertified smelter is identified in the supply chain, we ask suppliers to make revisions. In addition, depending on the improvement status, we review transactions and execute suspensions if necessary.

Step 4: Annual Updates on Initiatives

The initiatives undertaken are disclosed on our website on an annual basis.

Target

Renesas targets to identify 100% of conflict minerals (3TG) contained in our Group's products and to confirm that they are refined at Conflict-free smelters certified by a third-party organization, Responsible Materials Initiative ("RMI").

3TG Results*

*Scope excludes ex-Transphorm products

Renesas is committed to responsible mineral sourcing and conducts due diligence in line with the OECD Due Diligence Guidance. Based on supplier-reported information collected through the Conflict Minerals Reporting Template (CMRT), Renesas has identified that a portion of smelters in its upstream supply chain are currently designated by the Responsible Minerals Initiative as non‑conformant to RMAP. Because Renesas is a downstream manufacturer and does not purchase minerals directly from smelters, we rely on multi‑tier supply chain reporting and smelter status can change over time.

We are actively engaging with our Tier 1 suppliers to increase leverage upstream—encouraging smelters/refiners to participate in RMAP and, where conformance cannot be achieved, working with suppliers to transition sourcing to conformant alternatives. We will continue to monitor RMI status updates and transparently reflect progress through our regular reporting updates.

Cobalt and Mica Results

In 2019, we started identifying smelters in our supply chain for cobalt as well as 3TG. In 2023, in response to customer requests, we began to timely disclose our upstream suppliers’ smelter information based on the RMI's "Extended Mineral Reporting Template (EMRT)." Unlike 3TG, since there are currently no legal regulations regarding cobalt and mica, there is a risk that uncertified RMI smelters appear in our supply chain. These smelters may take time to be removed. As with minerals covered by our CMRT, if a smelter not certified by RMI is identified, we proactively work with our suppliers to take appropriate removal action.

Reporting of Investigation Results

Our initiatives related to conflict minerals are embedded into Renesas’ sustainability governance structure. To maintain transparency and accountability, the Sustainability Department regularly reports on sustainability-related activities and progress to the Audit & Sustainability Committee and the Board of Directors.
