The "Green OMRON 21" vision is made up of OMRON’s environmental management plan and an action plan for implementing it. OMRON’s environmental management promotion system consists of the Top Executives Environmental Meeting, the highest-ranking body chaired by the President. It is responsible for overseeing Group-wide environmental management, as well as supervising the Corporate Environmental Activity Committee chaired by an executive officer in charge of environmental matters. This committee meets twice a year in June and December to decide on Group-wide environmental measures and targets. In fiscal 2010, the committee decided on measures for reducing CO₂ emissions and building a chemical substance management system, as well as targets regarding creation of Eco-label products※1 and reducing the amount of CO₂ emissions. Environmental committees established within business companies then align these measures and targets with their business operations to individually plan specific environmental preservation activities and implement them at each site.

The Environmental Innovation Center※2 of the Global Business Process Innovation HQ※3 is tasked with planning and promoting environmental measures for the Group as a whole. The Corporate Environmental Activity Promotion Subcommittee established within the Environmental Innovation Center sets up working groups as necessary to conduct expert review for common environmental measures and issues shared across the Group. The subcommittee then submits the findings to the Corporate Environmental Activity Committee.

Established in fiscal 2009, the working group to study the environmental contributions of OMRON products and services has been working on the development of a method (formula) for estimating the power usage reduction by a product/service that is in use or on standby (see "Eco-Products" section). In fiscal 2010, a discussion was held with working group members regarding the revision of this formula and its management method to reach a consensus. The revised formula and proposed management method will be implemented beginning in fiscal 2011.
