In recent years, corporate environmental activities have come to span a wide range of areas, including pollution prevention, the reduction of greenhouse gas emissions and waste materials, regulations on chemical substances, and regulations on products containing hazardous substances. In accordance with our Environmental Policy and Action Guidelines, we promote the reduction of the environmental impact of our production activities and develop and sell environmentally-conscious products that improve our customers’ environmental performance.
We will contribute to creating harmony between society and the environment through the course of our business activities.
Environmental Action Guidelines
- We consider the environment in all stages of the product life cycle, including research & development, design, procurement, production, sales, logistics and use and disposal.
- We strive to prevent pollution and to minimize environmental impact (Note 1). When environmental problems arise, we take appropriate steps to minimize the environmental impact and disclose accurate information.
- Our environmental management efforts involve compliance with all environmental laws, regulations and agreements, and we promote compliance activities.
- We disclose environmental information to stakeholders and encourage transparency with society to promote mutual understanding.
- We educate all employees in environmental conservation to create a company culture that improves the balance between the environment and our business activities.
Note 1: Includes increasing energy efficiency, control and reduction of greenhouse gases, conservation of water, reduction, controlled use, reuse, recycling and pollution control measures of chemical substances and hazardous waste.
The Three Environmental Cornerstones of Our Environmental Activities
Key topics regarding our environmental activities are 1) compliance with laws and regulations, 2) reduction of environmental impact, 3) development of eco-friendly products, and 4) the maintenance of good relations with stakeholders.
We promote environmental management via a system called "Eco-Management Activities", with "eco-factory", "eco-product" and "eco-communication" initiatives as the three cornerstones of our environmental activities.
- Eco-Factory Initiatives [Initiatives to Reduce the Environmental Impact of Factories]
Initiatives to reduce the environmental impact at manufacturing sites by limiting and reducing greenhouse gas emissions and controlling chemical substances used in manufacturing
- Eco-Product Initiatives [Initiatives to Develop Environmentally-Friendly Products]
Initiatives to provide environmentally-conscious semiconductors throughout the product life cycle, such as the management of chemical substances contained in products and the development of products with low power consumption
- Eco-Communication Initiatives [Initiatives to Promote Environmental Education and Disclose Environmental Information]
Initiatives to raise employee awareness with environmental education, and activities to publicly promote Renesas’ environmental efforts
Business Activities and its Environmental Impacts
Semiconductor products and solutions provided by Renesas contribute to global environmental conservation activities, such as the prevention of global warming and effective use of resources, through energy saving and downsizing of customers' products and systems. On the other hand, it is also true that manufacturing consumes energy such as electricity and fuel, as well as resources such as chemical substances and water, and emits waste, effluents and emissions, which have a major impact on the environment.
We strive to reduce our environmental footprint by having a detailed understanding of our input and output volumes from production to logistics, and systematically reducing these inputs and outputs. Furthermore, we will continue to provide customers with eco-friendly products that are efficiently manufactured with limited resources and energy.

Compliance to Laws Related to the Environment
We accurately comply with all relevant laws and regulations of each country and region we operate in, and set and maintain a voluntary management standard which is stricter than various laws. If these standards are violated or if we receive any complaints, we reinforce environmental risk management measures by sharing the cause, countermeasures and preventative measures within the entire Group.
In 2020, there was one reported violation of laws and regulations, but has since been corrected. We did not receive any complaints.

Due to the characteristics of the semiconductor industry having a large impact on the environment, we believe it’s important to clarify the validity of necessary costs in environmental conservation activities, make appropriate investments and evaluate the results of such investments. These steps are needed to mutually balance environmental conservation with our business. To further support this goal, we have introduced Environmental Accounting since the establishment of Renesas.
