Basic Policies

OMRON considers that promotion of anti-climate change measures is an important social responsibility that the company must take on now and into the future. Accordingly, Group-wide efforts are being concentrated on promoting energy conservation to ensure the achievement of Japan’s Kyoto Protocol target (a 6% reduction in greenhouse gas emissions compared to fiscal 1990).

For overseas sites, OMRON has specified a target in terms of emissions per unit of production instead of total emissions, aiming to enhance energy usage efficiency. This is because the reduction of energy usage is difficult with the ongoing business expansion strategy, and the total emissions targets differ greatly among countries.

Reflecting its globally expanding business, OMRON set a new goal of improving carbon productivity (sales / total CO2 emissions) by 30% compared to the fiscal 2010 level. The goal is to reach this achievement on a global basis by fiscal 2020. OMRON is currently working hard to meet this goal.

Specific measures being taken to meet this goal include appropriate temperature settings for heating/cooling, controls on daily usage of electricity, reduction of energy consumption through the promotion of visualization using energy monitoring systems, and the deployment of energy-efficient devices and clean energy equipment.

To fulfill its responsibility as a manufacturer, OMRON will also specify targets for the degree of contribution to CO₂ emissions reduction in society through its products and services.

FY2010 Overview

【Japan】
In Japan, OMRON has been working to achieve its Group-wide target of reducing total CO₂ emissions by 8.6% below the fiscal 1990 level by fiscal 2010. This target was set in line with its environmental action plan, "Green OMRON 21" established in 2002. However, emissions increased significantly due to the Yasu Factory, which engages in the production of semiconductor-related components. The factory joined the Group through M&A during fiscal 2007. Therefore, OMRON revised the target by taking the Yasu Factory’s increase into account.

In fiscal 2010, OMRON emphasized more exacting daily control of energy usage at its business sites. Specific activities implemented included appropriate air conditioner temperature settings, and power-off for unnecessary lights and PC monitors when staff members are away from their desks. Replacement of lighting fixtures, air conditioners and compressors with energy-efficient types also moved forward. OMRON’s energy monitoring systems were also deployed in its production sites in Japan aiming to promote visualization of energy usage and improvement of equipment operations.

As a result of these efforts, CO₂ emissions in Japan amounted to 72,269 metric tons, nearly the same as the fiscal 2009 level (72,967 metric tons). However, because production volume increased 23% in Japan compared to the previous year, OMRON was able to mark a significant improvement in CO₂ emissions per unit of production. When compared to the fiscal 1990 level (61,060 metric tons), which was the reference year specified before the Yasu Factory joined the OMRON Group, total emissions increased 18%.

Going forward, OMRON will aim to further reduce CO₂ emissions by continuously promoting on-going energy conservation initiatives, while also adopting equipment control suitable for the conditions of production sites, as well as encouraging employees to wear "Super Cool Biz" outfits in offices.

【Overseas】
In fiscal 2010, CO₂ emissions from overseas sites increased 13% from the fiscal 2009 level to 63,366 metric tons. This increase was mainly attributed to the transfer of production functions from Japan and setup of new factories outside Japan, as well as a 15% rise in production compared to the previous year.

However, energy-saving efforts promoted at each site led to improvements in CO₂ emissions per unit of production. CO₂ emissions per 100 million yen of production decreased 8.6% from the fiscal 2002 level (44.6 metric tons per 100 million yen of production), meeting the target of an 8% reduction in CO₂ emissions per unit of production compared to fiscal 2002.

In fiscal 2011 and beyond, the OMRON Group will continue its energy conservation activities toward the goal of improving carbon productivity (Sales per CO₂ emissions) on a global basis.

At the Ayabe Factory, energy conservation efforts previously concentrated on equipment such as air conditioners and lighting fixtures. To promote measures that are more closely associated with production operations, the factory set up a project team aiming for both energy conservation and productivity improvement.

Rather than make a simple assessment of current energy usage, the Ayabe Factory recognized the importance of building a system that encourages production staff to maintain awareness of wasted or inefficient use of energy for themselves and adopt necessary measures on their own initiatives. Based on this awareness, various OMRON sensors were installed on production equipment and lines. A communication board system was also deployed so that staff can check power consumption, the amount of dust particles, humidity, temperature and air flow via the in-factory display. This system allowed the Ayabe Factory to further improve its operations by issuing an alarm if measurements are likely to exceed control values, ensuring that a manager comes to the workplace immediately to evaluate the situation.

These improvement efforts helped production staff to enhance energy-saving awareness. The result was a halving of power usage for the production line employing a communication board system. This system is now in operation at the clean room and other processes on the same floor. In the future, the Ayabe Factory is determined to expand its efforts beyond elimination of wasted energy to include reducing variations in operating conditions and electricity reserves.

OMRON has been promoting the deployment of its energy monitoring system for its Japanese production sites. This system measures total amount of energy usage at each factory building and by each machine. Through the employment of this system, OMRON aims to extract inefficiencies and losses, such as unevenness in energy usage or equipment operation during off-hours or on holidays, for heat pumps, air conditioners, compressors and clean room air blowers. After points requiring improvement are discovered, improvement measures are devised by involving on-site workers, and are tried out at one location. If a particular measure is found to be effective, it is documented in a manual so that it can be adopted for other equipment and at other buildings. By implementing this CAPD (Check-Act-Plan-Do) cycle, OMRON expects to gradually reduce energy usage for the entire production site.

Outside Japan, five out of seven sites in China underwent energy conservation diagnoses aiming for the deployment of the energy monitoring system. Diagnoses resulted in extraction of a potential CO₂ emissions reduction of 6-10% through operation improvements, and a reduction of 7-15% through investments in equipment. Based on this result, deployment is planned for three additional sites in fiscal 2011.
