Operating the Environmental Management System (ISO14001)
The IRISO Group has set up an environmental management system by following the ISO 14001 to conduct activities for environmental improvement.
The environmental management system is run on the PDCA (Plan-Do-Check-Act) cycle mainly by a project management office that was set up at each manufacturing base. The departments of each manufacturing base follow the instructions of the project management office, create and implement annual plans, and report the activity results to the office. The office conducts internal audits to check the final results and validity of the plan, and the results are summarized and reported to the environmental manager. In addition, the validity of the plan is confirmed through an audit performed by an external organization. The following are the years when the manufacturing bases got ISO 14001 certified. Since they were certified, they have had external audits under ongoing basis.
ISO14001 Certified Years for Group Manufacturing Bases

Internal Audits
“Internal Audits" are conducted at each manufacturing base* to verify that the environmental management system works effectively.
*The headquarters/Kawasaki Center and all group plants (excluding sales companies/offices in Japan and outside Japan). The ISO Standards are scheduled to be applied to Iriso Engineering Co. Ltd., which joined our group in 2022 and will be one of the group manufacturing base in Japan from FY2024, as well as to the Akita Plant, which will start operation in 2025, from FY2026 (currently, not applied yet).

Our Environmental Conservation Practices
Our environmental policy was announced under the name of the company CEO both within and outside the company to declare that we are engaged in the following environmental conservation activities.
・Reduction of CO2 and other greenhouse gas emissions (by promoting energy conservation)
・Effective use of recycled resources
・Running eco-friendly activities (compliance with environmental laws and regulations)
Details of our environmental conservation practices are given below.
Reduction of CO2 and other greenhouse gas emissions (by promoting energy conservation)
Greenhouse gases mainly include carbon dioxide, methane, dinitrogen monoxide, hydrofluorocarbons, perfluorocarbons, and sulfur fluoride. Greenhouse gases come from our production activities because we use electricity and automobiles. Greenhouse gases are a cause of global warming, and we are running the following activities for managing greenhouse gas emissions to stop global warming.
| Measure | Results |
|---|---|
| Solar panel installation | One of our ways to reduce our electricity consumption is solar panel installations at our Ibaraki, Shanghai, and Nantong Plants. 1,470MWh of electricity was generated by the solar panels in FY2022. As a result, CO2 emissions were reduced by 497.3 tons. |
| Improve air-conditioner efficiency | The air conditioners at the headquarters will be replaced between 2022 and 2025. In so doing, we expect to reduce annual electricity consumption at the headquarters by 135 MWh. |
Effective use of recycled resources
We promote the 3Rs (Reuse, Reduce, Recycle) practices at all group bases both in Japan and outside Japan.
The results are presented below.
| Measure | Results |
|---|---|
| Cutting down on gold in connectors and using recycled materials | ①By reviewing gold plating proportion, thickness, and processing part of connector pins, we have cut down on gold in production. ②By using recycled Liquid Crystal Polymer (LCP) resin for connector molds, we have reduced plastic waste. |
| Separation of waste materials for reusing as valuable resources | We do not dispose of materials such as copper scrap, gold plating, and waste products generated at all group sites both in Japan and outside Japan. We make effective use of them by sorting as valuable resources. In FY2022, we were able to reduce our CO2 emissions by 2,083.7 tons in terms of carbon footprint. |
| 3Rs Practice | The headquarters is fully engaged in daily 3Rs activities, the separation, reduction, reuse, and recycling of wastes. Since 2008, we have been recognized by the City of Yokohama as an excellent company in the practice of 3Rs for our outstanding waste management practices. We are continuously committed to our 3Rs practices. |
| Social Responsibility | We run the following activities to work towards a better society.
|
Running eco-friendly activities（Compliance with environmental laws and regulations）
We run an array of eco-friendly activities in compliance with environmental laws and regulations. We manage wastes in accordance with the Waste Disposal and Public Cleansing Law, conduct quick and periodic inspections of air conditioners, testing equipment and others in accordance with the CFC Emission Control Law, and perform periodic measurements in compliance with the Noise Regulation Law.
