Environmental Initiatives
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. With our CEO's approval and 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 are sharing Environmental Action Guidelines with Renesas Group employees through in-house trainings.
Environmental Policy
We will operate our business in a way that will allow us to both preserve the environment and support the healthy lives of people, with the goal of realizing a sustainable society.
Environmental Action Guidelines
At Renesas, we will strive to foster a sustainable society that can last decades, by providing environmentally-friendly semiconductor products and solutions throughout their entire life cycle, from research and development, design, procurement, production, sales, distribution, use, to disposal.
We are committed to reducing our environmental impact and preventing environmental pollution in all areas of our business. At the same time, we will comply with environmental laws and regulations and continue to improve our global environmental management system.
- Response to Climate Change
We will strive to reduce energy consumption throughout the value chain, use energy efficiently and minimize greenhouse gas emissions, to support the goal of becoming carbon neutral. - Effective Use of Resources
We will make efficient use of all resources required for our businesses. In particular, we will strive to use water resources appropriately, minimize waste, and promote recycling. - Biodiversity Conservation
We will contribute to biodiversity conservation through our business activities and promote the concept of biodiversity that is critical in supporting a rich and healthy society.
We will help build a better society by proactively disclosing environmental information with our stakeholders to establish mutual understanding and by actively communicating with them.
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.
For more details on environmentally-friendly products, please refer to Sustainable Products and Solutions.

In order to calculate CO2 emission level calculation in relation to electricity, we have used the factor provided by the "List of Calculation Methods/ Emission Factors in the Calculation, Report and Publication System" of the Ministry of the Environment and the Ministry of Economy, Trade and Industry of Japan, adjusted conversion factors for individual power businesses based on the Act on Promotion of Global Warming Countermeasures. For figures that represent outside of Japan, the latest values for the each fiscal year supplied by power supply companies. When the CO2 emission levels are uncertain, we use the conversion factors of previous year. For the CO2 emission factor for gas and fuel at the time of calculation, we used the factor provided by the "List of Calculation Methods/ Emission Factors in the Calculation, Report and Publication System" of the Ministry of the Environment and the Ministry of Economy, Trade and Industry of Japan.

Eco-Management: Environmental Management Activities
We promote environmental activities by establishing environmental management systems at each site, including affiliated companies.
Environmental Management System
The Environmental Policy and the Basic Rules of Environmental Management are defined in Renesas's Basic Management Rules. We have established an environmental management system across all offices and sites including partner companies to promote environmental activities. The Environmental Promotion Department oversees all of Renesas’ environmental activities. The Environmental Promotion Department reports and makes suggestions on results of various environmental activities, challenges and issues to the company’s top management.

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 2022, there were no violations of laws and ordinances or complaints.

Environmental Accounting
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.

- Investments:
In 2022, we invested 2,367 million yen for pollution prevention and energy conservation measures, etc. We invested mainly related to reducing soil contamination risk and installed and replaced equipment which allows efficient use of energy. - Expenses:
In 2022, we spent 4,228 million yen as expenses. The main items included maintenance and management costs for equipment related to pollution prevention at each production site, and depreciation costs related to investments in energy-saving equipment. - Economic Impacts:
The economic impact in 2022 was 1,725 million yen. The breakdown of this mainly consists of impacts from energy conservation measures, as well as the recording of 713 million yen in sales of waste through recycling. However, this figure does not include economic impacts based on hypothetical calculations.
Participating Initiatives and Organizations
