Eco-Product Initiatives

Our eco-product initiatives take the form of creating environmentally-conscious products and solutions

Creating Environmentally-Conscious Products

In order to create environmentally-conscious products, it is important to reduce the environmental impact at all stages of the product lifecycle, from procurement, manufacturing, use and disposal. Our eco-products are the result of product environmental assessments which evaluate the total environmental impact reduction measures. During these product environment assessments, our products are tested and evaluated at two stages: at the development stage and before mass production.

Environmental Assessments of Products

We create environmentally-conscious products by incorporating product environmental assessments into the product development and design flow, to evaluate the degree of improvement in environmental load. In this evaluation, we make comparisons between our products with pre-existing products based on eight criteria, including weight reduction, product safety, and whether they are energy saving. The results are quantified and can be visualized in charts. Our semiconductor products are designed to improve their own environmental performance and, when build into our customers’ systems, they will further contribute to reducing the size and energy consumption of customers’ products. As a result, the environmental impact for the final customers using our finished products will also be reduced.

Renesas Green Devices

Following the product environment assessments, products that have been evaluated to exceed a certain level of environmental performance are certified as "Renesas Green Devices.” Of these, products with an even better environmental performance are sorted and internally certified as "Renesas Super Green Devices."
Renesas Green Devices and Renesas Super Green Devices, which have been certified as excellent in environmental performance from hundreds of developed products per year, have been registered to a database, and some of these products are displayed as an easy-to-see indicator of their environmental performance. For more information, please refer to past Environmental Reports or contact our sales department or sales distributors.

Environmental Performance (according to our internal standard)

★ to ★★  "Renesas Green Device"
★★★ to ★★★★★ "Renesas Super Green Device"

In addition to the above, there are many products certified as "Renesas Green Device" and "Renesas Super Green Device."

Product Environmental Quality

We believe that it is necessary for the entire supply chain to manage chemical substances contained in products throughout the entire process, from the selection of materials during development and design, to the prevention of pollution in the manufacturing process. For this reason, we ask suppliers to submit certificates and analysis data to confirm that prohibited substances are not used and they adhere to such practices in supplier audits.
Distributors are requested to manage the chemical substances contained in the packaging materials they use. On the other hand, we also provide our customers with information on chemical substances contained in products and analysis data on prohibited substances according to the RoHS Directive to ensure that our products can be used safely. In addition, we show our customers our systems for managing chemical substances and actual environmental activities.

Energy-Saving Devices

We deliver energy-saving products and solutions that support our customers' electronic equipment and systems. Some of the products and solutions we deliver consume very little power themselves, and some help further reduce energy consumption in our customers' systems when used. By actively developing such devices, our devices contribute to energy efficiency in society..

For details of our products and solutions that contribute to ultra-low power consumption and energy efficiency in our customers' systems, please refer to this link.

Contributing to SDGs

Renesas’ efforts in Eco-Product Initiatives contributes to these Sustainable Development Goals targets:


12.4 By 2020, achieve the environmentally-sound management of chemicals and all wastes throughout their life cycle, in accordance with agreed international frameworks, and significantly reduce their release to air, water and soil in order to minimize their adverse impacts on human health and the environment
