The Group’s Business Activities and Environmental Footprint
The semiconductor products and solutions offered by the Renesas Electronics Group help our customers make their own products and systems smaller and more energy efficient. This boosts protection of the global environment by helping to prevent global warming and use resources effectively.
On the other hand, it is true that production activities place a large environmental loads. They consume energy (electric power, fuel, etc.) and resources (chemicals, water, etc.) while producing waste in solid, liquid, and gaseous forms.
We are attempting to reduce our environmental loads by conducting detailed measurements of our volume of input and output from production to distribution, and making planned reductions.
The Renesas Electronics Group is committed to using limited resources and energy in an effective manner and to offering eco-friendly products that are manufactured efficiently.
Compliance system for environment related laws and internal audits of the environment management system
The Renesas Electronics Group's Basic Rules of Management set out the Environmental Policy and Basic Rules of Environmental Management. Following these guidelines, all of our bases, including affiliated companies, established their own environmental management system and are proceeding with environmental management activities. Each year, we audited the environmental management system of each base to monitor continuous improvement of performance. In FY 2018, we audited 12 sites including the overseas sites. As a result, 162 recommendations including 44 requests for improvement were extracted, and improvement actions were taken. To maintain highly reliable audits, our audits are conducted by CEAR*1-certified qualified auditors. Furthermore, in response to environmental laws and regulations, which are becoming stricter every year, we constructed an information-sharing system and are monitoring the system and the compliance status of all sites.

All domestic sites and overseas manufacturing sites have been certified under ISO 14001, which is the international standard for environmental management systems. The Renesas Electronics Group will continue to maintain and deploy ISO 14001 certification effectively and efficiently. In FY 2018, the ISO 14001: 2015 certification was renewed.
For investments in fiscal 2018, we implemented measures to save energy, which included the renewal of refrigerating machines, compressors, dry pumps, and boilers, by optimizing control via inverters and introducing equipment for efficient energy use, such as equipment for the reuse of cold air in winter and waste heat and for the use of heat of vaporization. For expenditures not listed in the tabulation results table, we posted 460.8 million yen for the prevention of air pollution, 1280.3 million yen for the prevention of both soil and water contamination, and 446.1 million yen for waste disposal.
Among the economic effects not listed in the tabulation results, the gain on the sale of waste was 565.7 million yen, which does not include estimated economic effects obtained from hypothetical calculations.
