Eco-Product Initiatives

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

Eco-Product Initiatives

To realize eco-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.


Eco-Product initiatives at each stage

Creating Environmentally-Conscious Products

Our way to create environmentally-conscious products is to incorporate product environmental assessments into the product development and design flow, to evaluate the degree of environmental impact improvement. 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 improve their own environmental performance and, by building them into our customers’ systems, contribute to the miniaturization and energy saving of products at the customer’s side. 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 prohibited substances are not used and confirm their management system 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 (Note) 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.

Note: 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.

Energy-Saving Devices

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