Ratio of global sales to CO2 emissions (from global production sites *1): 30% improvement compared to FY2010 results. *2
To help achieve a low carbon society, OMRON will strive to reduce CO2 emissions. Moreover, the OMRON Group, as a whole, will promote more efficient manufacturing operations aimed at minimizing energy and resource usage (Eco-Monozukuri).
The ratio of the OMRON Group’s global sales to CO2 emissions from global production sites improved by 27.5% compared with the FY2010 level. This is the result of seven years of initiatives from FY2011 to FY2017. OMRON’s efforts to promote Eco-manufacturing to reduce energy usage have consistently proved productive in reducing CO2 emissions.
In FY2017, OMRON set environment-related social issues to address, together with the company's identified sustainability issues and long-term goals.
|Carbon productivity (millions of yen/t-CO2)||3.31||3.60||3.83||4.12||3.94||4.22|
|Total CO2 emissions from production sites
|Sales (millions of yen)||617,825||772,966||847,252||833,604||794,201||859,982|
To assess the environmental impact of OMRON’s business activities as a whole, including its value chain, OMRON in fiscal 2013 began calculating Scope 1, 2, and 3 of the OMRON Group’s greenhouse gas (GHG) emissions. The calculation is based on the GHG Protocol, which is the most widely used international accounting and reporting tool.

To ensure the reliability of its data, the OMRON Group’s GHG emissions data (Scope 1, 2, and 3) underwent third-party review by Bureau Veritas Japan Co., Ltd. OMRON received a report that verified appropriate measurement, calculation, and reporting of GHG data, including source data, or evidence.
|Category||Verification source data (evidence)||Verification standard|

OMRON has been working on Eco-manufacturing, making the best use of limited resources for sustainable manufacturing.
In fiscal 2017, as Eco-manufacturing initiatives, OMRON worked on facility improvement, facility investment, and introduction of optimization equipment to production sites. Examples are as follows.
(1) SHANGHAI OMRON CONTROL COMPONENTS Co., Ltd., a production site in China improved energy efficiency of air conditioners and repaired air leakage of compressors, to reduce electricity consumption by 2,400,000 kWh, or 1,687 t-CO2 a year.
(2) OMRON has been working on the introduction of energy control system*3 designed to automatically determine operation, stand-by, and stoppage of the related manufacturing lines based on the status of power consumption by equipment. The system was introduced to a molding line in China.
(1) SHANGHAI OMRON CONTROL COMPONENTS Co., Ltd., a production site in China, added inverters to the equipment.
(2) P.T. OMRON MANUFACTURING OF INDONESIA, a production site in Indonesia, introduced and is utilizing building automation systems.
(3) OMRON Aso Co., Ltd., a production site in Japan, introduced and is utilizing central air conditioning management systems.
In total, the 3 sites reduced electricity consumption by 180,000 kWh, or 107 t-CO2 a year.
Two production sites in Japan, OMRON Kusatsu Office and OMRON Relay & Devices Takeo Office, introduced energy transformation equipment*4 in order to optimize energy use at each site. With the equipment that can change heating oil/ gas to electricity, the two sites reduced GHG emissions by 540 t-CO2/year in total.
Five production sites in Japan and China utilize renewable energy generated by solar power systems. The amount was 765 MWh, equivalent to 504 t-CO2.
OMRON monitors the usage of GHG other than energy-oriented CO2.
