Eco-Products Initiative

Customers’ environmental requirements for our semiconductor products are growing stricter every year. The Renesas Electronics Group is proceeding with its Eco-Products Initiative to meet these requirements. To turn a product into an eco-product, it is important to build in a variety of innovations at the development and design stages to reduce environmental loads at all life cycle stages, including procurement, production, usage and disposal.

Our eco-products are made possible through product environmental assessments, which are comprehensive evaluations of the product environmental loads reduction measures. Product environmental assessments are divided into two stages: At the time of development and prior to mass production.


Eco-Products Initiative at Each Stage

Creation of Eco-Friendly Products

As a way to create eco-friendly products, we include a product environmental assessment, a way of evaluating how much a project mitigates environmental loads, into our development and design flow. The evaluation compares new products against old ones in eight categories, including volume reduction, product safety, and energy savings. The process yields quantifiable results that can be visualized, for example with charts. This helps improve the performance of our semiconductor product itself, and when used in our customers’ products, helps make them smaller and more energy-efficient. This ultimately decreases the environmental loads of the customers who use those products.

Renesas Green Device

The Renesas Green Device is internally certified as a product with an assessed environmental performance above the set criterion level. Products with higher environmental performance are selected and certified as Renesas Super Green Devices. The Renesas Green Devices and Renesas Super Green Devices selected from hundreds of newly developed products every year are registered in our database. Some of these products are presented on our website with an environmental performance index.

Product Environmental Quality

To customers, we provide information on substances contained in our products and analysis data on the substances prohibited by the Restriction of Hazardous Substances (RoHS)*1 at the request of customers to ensure that our products can be used safely. Moreover, we offer opportunities to check our chemical substances control system and actual environmental protection activities. We think that chemical substances used in all processes from selection of materials at development and design phases to pollution prevention in the manufacturing processes must be controlled by the whole supply chain. To suppliers, we ask them to submit a certificate and analysis data to ensure that the prohibited substances are not used. Additionally, we perform supplier audits to check their control systems. To distributors and special agents, we request them to control chemical substances contained in packaging materials.


*1 RoHS Directive: EU directive for restrictions on the use of certain hazardous substances (lead, mercury, cadmium, hexavalent chromium, bromine-based flame retardants (PBB and PBDE), and phthalic acid esters (DEHP, BBP, DBP, and DIBP)) in electrical equipment.

Promoting Green Procurement

Renesas Electronics is promoting green procurement. Specifically, the Company prioritizes the procurement of ecofriendly products free of hazardous substances from suppliers who are proactively promoting environmental protection. These guidelines are disclosed to all suppliers and the Company conducts periodic investigations on the environmental measures implemented by suppliers. In addition, the Company advances its procurement initiatives with the understanding and cooperation of our suppliers in relation to testing of purchased items for hazardous substances, compliance with the European Union's RoHS directive and other laws and regulations.

Compliance with Environmental Laws and Regulations

Embedded in a wide range of finished products, Renesas Electronics’ semiconductors are being used worldwide. In order to ensure compliance with environmental laws and regulations related to its products Renesas Electronics is working to obtain information regarding such laws and regulations in major countries immediately after its publication.

Major Environmental Laws Overseas and Our Response

The RoHS Directive and the ELV Directive*1 of the European Union have defined threshold values for chemical substances contained in certain products. In response to these and similar directives, Renesas Electronics makes sure that it receives product analysis data from suppliers of semiconductor device components as well as reports certifying that their products are free of banned substances. In addition, we conduct voluntary analysis of these components to confirm that sub-threshold values are observed.

*1 ELVDirective: EU directive on End-of-Life Vehicles. Limits content of lead, mercury, cadmium and hexavalent chromium.

Initiatives in China

China's Administrative Measures for Restrictions on the Use of Hazardous Substances in Electrical and Electronic Products, also known as Amendment China RoHS, requires an indication of the hazardous substance used and the product Environment Friendly Use Period (EFUP) for end products that contain specified toxic and hazardous substances. Semiconductor products are not electrical and electronic end products, so information related to each chemical substance contained in products and product Environment Friendly Use Period (EFUP) values is provided through sales companies and authorized dealers without directly marking the products.

Initiatives in Europe

Renesas Electronics is not required to register its semiconductor devices under the EU’s REACH Regulation*2, since they are articles (finished products) that do not intentionally emit chemical substances. However, we obtain the products containment information related to substances of very high concern (SVHCs*3) from the supply chain and provide it to customers.

The Group will continue to closely monitor movements of environmental laws and regulations overseas and implement appropriate measures.


*2 REACH Regulation: Regulation on Registration, Evaluation, Authorization and Restriction of Chemicals. Requires registration and evaluation to produce or import chemical substances in the EU, requires authorization for substances of very high concern, and sets limits (including bans) on high-risk substances.

*3 SVHC: Substances of Very High Concern (because they harm or may harm health and safety.)
