OMRON considers addressing environmental issues to be its corporate responsibility and thus is an important management objective for the Group. Accordingly, OMRON established its new basic policies for the environment, consisting of "environmentally conscious business activities" and "environmental conservation activities" in the OMRON Group CSR Practice Guidelines.

As for environmentally conscious activities, while working to lessen the negative impact on the environment arising from its business activities, the OMRON Group will also remain committed to developing and promoting products and technologies that help conserve natural resources and the environment. OMRON also aims to implement environmental management practices that enhance both ecology and economy. To build a solid base for environmental management, OMRON will provide all employees with environmental education and awareness-raising opportunities in order to encourage an ecological mindset.

In the area of environmental conservation activities, OMRON recognizes that actions implemented by all concerned organizations and individuals are crucial for the promotion of conservation of natural resources and the environment. As such, the OMRON Group, together with relevant organizations, will proactively engage itself in solving the environmental issues that society faces, such as prevention of global warming. All OMRON Group directors and employees are expected to demonstrate concern for environmental protection, even in private activities away from work, and to act in an environmentally conscious manner.

In 2002, OMRON established "Green OMRON 21," an environmental vision that determines the direction of OMRON's environmental management as a "21st century company," and an action plan that clearly identifies focused activities and targets.　Green OMRON 21 is designed to promote activities in six key areas, namely Eco-Management, Eco-Products, Eco-Factories/Laboratories/Offices, Eco-Logistics and Eco-Communication, centering on Eco-Mind. This aims at the long-term maximization of OMRON's corporate value and contributing to the development of a sustainable society.

In October 2005, OMRON reviewed the areas of activities and targets formerly specified and established a new action plan (Ver. 2) with a new target year set for 2010, the final year of GD2010.

The corporate-wide action plan is shared with all business companies, Head Office administrative divisions and sites under their control and incorporated into their individual action plans. Each site's implementation of the action plan is inspected by corporate audits.
