Environmental Contribution


Environmental contribution*1 > CO2 emissions from global production sites

  • *1 Environmental contribution: Volume of CO2 emissions reduction contributed by society’s use of the OMRON Group’s energy generation and energy saving products and services.

Our Stance

OMRON strives to offer products and services beneficial to the global environment. The aim is to make the reduction in environmental impact through its products and services greater than the environmental burden caused by its production activities. In this way, OMRON will work to expand the company’s environmental contribution in order to help lessen environmental impact in a more efficient manner.

FY2017 Overview

In fiscal 2017, OMRON achieved an environmental contribution amounting to 659 thousand tons of CO2. This shows OMRON’s significant contribution to reducing environmental impact through its business activities. It also means that OMRON’s environmental contribution was far greater than the total CO2 emissions from OMRON Group production sites worldwide (204 thousand tons of CO2) for six consecutive years.

Environmental Contribution Accounting Methodologies

At OMRON, the degree of environmental contribution is accounted from direct effects of the products themselves, and indirect effects through the use of products or services.

Direct effects

Reduction in CO2 emissions by improved energy-saving performance of an OMRON product compared to a reference product.

  • * Calculation formula
    Energy-saving effect (W/units) × Operation time (hours/year) × Average number of years in use × CO2 emission factor × Number of units sold in a year
  • * Examples of applicable products
    Energy-saving nebulizer, safety sensor, industrial temperature controller, general-purpose power supply

Indirect effects

Reduction in CO2 emissions achieved by an OMRON product’s contribution to a customer’s energy generation or conservation, through its incorporation as a core component of the customer’s product that saves or generates energy.

  • * Calculation formula
    Environmental contribution by a customer's product in a year (kWh/Unit of year) × Average number of years in use × Degree of contribution × CO2 emission factor × Number of units sold in a year
    The CO2 emission factor used for the calculation is 0.392kg-CO2/kWh.
    The calculation formula is for products’ utility power.
  • * Examples of applicable products
    PV inverter, AC/DC converter for EVs, HEVs, and PHEVs, electric power steering controller
