Environmental Management System

Preservation of the Global Environment

To engage in the protection of the global environment as a united Group, we have declared common policies and goals and developed management systems based on a common manual. We are pursuing continuous improvements with the aim of solving a variety of issues.

Organization / Environmental Management Promotion System

ROHM Group

ROHM has deployed across the ROHM Group an environmental management system designed to be shared among the Group on the basis of the International Environmental Standard ISO 14001 and all employees have been working on continual environment improvements. Furthermore, the ROHM Group has been implementing constant environmental activities from a global perspective on a consolidated basis.

Rohm headquarters was the first to obtain ISO14001 certification in May 1998, and each of our Group companies has since completed individual certification. However, we consider action on environmental issues not as a matter for the individual companies of the Rohm Group, but as something that the Group will engage in as a whole. To clarify individual companies' actions and Group-wide actions and to standardize effective environmental activities and information, the Japanese Group companies and ROHM KOREA joined forces to obtain integrated ISO14001 certification in November 2000.
Our overseas production sites have also developed environmental management systems, based on the self-declaration of ISO14001 standards. To maintain these management systems at a level that is on a par with Japan, the environment manager at Rohm head office strictly evaluates and certifies the appropriateness of those self-declarations.

ROHM Group's environmental management promotion system

Under this framework, all actions related to the environment are conducted under the direction of the Rohm Group's environment general manager. By extending the outcomes of those actions horizontally to the other Group companies, Group-wide environmental protection action is being achieved.


ROHM started the environmental management promotion system in its Headquarters in 1990 mainly to conduct pollution prevention activities, and rebuilt it afterward to a promotion system taking environmental conservation with a view to the global environment as a principle behind its activities. In this rebuilt promotion system, the "Environmental Conservation Measures Committee" that deliberates significant policies and measures relating to the environmental activities, and five subcommittees and two working group that comprise the Committee are playing an important role in the promotion system. The subcommittees are composed of experts in the relevant field, engineers, and related national qualification holders, and the chairpersons of the subcommittee serve as members of the Environmental Conservation Measures Committee. The Management Committee and subcommittees and working group meetings are held once a month on a regular basis. Group companies are also establishing the same environmental management promotion system.

Integrated Internal Environmental Audit

To confirm the effectiveness of Group companies' environmental management systems and the status of their compliance with relevant legislation, an audit team from Rohm head office conducts an Integrated Internal Environmental Audit once a year. Other objectives of this audit are the continuous improvement of the systems and the elevation of environmental performance.

Environmental Liaison Conference

In the Rohm Group, the Environmental Management Responsible Officers and Environmental Managers of each site come together once every two years to hold an Environmental Liaison Conference, where they share their annual targets and implementation plans. At the Conference, the attendees confirm the state of progress at each site and consider environmental issues for the Group as a whole.

At the FY2017 Conference, discussions concentrated on issues concerning the achievement of the 2020 Environmental Objectives (Mid-Term Targets). The decision was made to strengthen the initiatives being taken to reduce the entire Group's environmental footprint (elevate environmental performance), and action is being taken toward that end.

Approaches to Environmental Communications

The Rohm Group promotes environmental awareness-raising activities to deepen individual employees' understanding of the connections between the global environment and Rohm's business activities, and the implementation of environmental activities. The Group is also strengthening its ties to the local communities through a variety of activities.

Approaches in "Environmental Education"

Rank-based environmental education

To train employees in considering their living environment and the global environment, we have implemented education based on the rank of employees to teach how their respective work is related to the environment and how important the environmental management system is, through training for new employees and rank-based training.

Environmental Education for Employees at Overseas Sales Locations

So our customers may use our products with peace of mind, the Rohm Group continues to engage in the management of substances of environmental concern (SOC).
At our sales locations, which act as the contact point with our overseas customers, with the objective of increasing staff's environmental knowledge, we educate employees on the mechanisms of SOC management and the importance of collaboration with suppliers.

Education in Taiwan

Environmental education for elementary school students

The ROHM Group has provided environmental education for elementary school students in Kyoto-city from FY 2010. In the education program, we give the opportunities for them to experience the energy-saving effects such as comparing the energy-consumption of LED and miniature bulbs by using a human powered generator besides the lecture about global-warming's mechanism, and energy-saving tips that can be performed at home or school.
The ROHM Group will continuously develop these kinds of activities that help children understand the value of global environment.

In 2017, we provided environmental education to 200 students from four different elementary schools, and so far, a total of 1410 elementary students have received our environmental education.

Light-down Campaign

Rohm's head office and its Kyoto Station and Shin-Yokohama Station locations are participating in the Ministry of the Environment's "CO₂ Reduction/Light-down Campaign." For the FY2018 Campaign as well, they turned off the lights on all logo billboards on their buildings" exterior walls, as well as the Kyoto Light History lighting display.
The CO₂ Reduction/Light-down Campaign, which began in 2003, calls on lighting facilities around the country, as well as private homes, to turn off their lights as an action for the prevention of global warming. In 2018, the two hours from 8:00 p.m. to 10:00 p.m. on June 21 (summer equinox) and July 7 (Cool Earth Day*) were set as the days on which participants would all turn off their lights at once. By participating in the Light-down on both nights, Rohm reduced its power consumption by about 68 kWh.
Rohm will continue to participate actively in these kinds of global environmentally friendly initiatives.
