Initiative to calculate volume of avoided CO2 emissions by product
As a part of our green transformation (GX) activities, we began quantifying the amount of CO2 emission reduction contribution by our products this fiscal year.
We will continue to engage in technological development and expand "Beyond Zero," which refers to "the volume of avoided CO2 emissions by our products that exceeds our own emissions."
Calculation method and results
The contribution was calculated in accordance with Japan Electronics and Information Technology Industries Association (JEITA) guidelines. "Effect of CO2 emission reduction at the time of use of products" indicates the amount of power consumption reduction when comparing the power consumption of the evaluated product with the power consumption of the same product equipped with previous generation parts.
Definition of the volume of avoided CO2 emissions
* We sell parts used in final products, so "product" refers to the final product.
Actual volume of avoided CO2 emissions and target
Fan motor bearings
Volume of avoided CO2 emissions
Approx. 1,293,000 t-CO2
Bearings support rotating shafts and are the most important part of rotary components such as motors.
We specialize in miniature ball bearings, which are used in fan motors, which are used widely in IT-related electronic devices and components for cooling.

Technical strengths
Bearings fall into the category of precision technology and support precision and extended life of motors. In addition, leveraging tribology technology, they reduce friction, improving the energy efficiency of fan motors, in other words, contributing greatly to the reduction of CO2 emissions.
Smart LED street lights
Volume of avoided CO2 emissions
Approx. 135,000 t-CO2
Street lights ensure visibility so that roads can be driven safely and smoothly. The brightness and uniformity are regulated.
Our LED street lights conform to these regulations and offer the industry's highest level of energy efficiency, contributing greatly to conservation of energy.

Technical strengths
Proprietary light distribution technology cultivated in development of backlights for smartphones is used to create high efficiency optical lenses. In addition, a wireless network allows the lights to be adjusted remotely according to time of day and traffic volume for further energy savings.
AC adapters, chargers, and built-in power supplies
Volume of avoided CO2 emissions
Approx. 28,000 t-CO2
AC adapters and chargers are converters that supply the required voltage, current, and power to devices from power sources such as commercial power and batteries.
We manufacture a wide variety of these products.
MinebeaMitsumi's products offer a high degree of energy savings, a major element of performance of these products.

Built-in power supply
Technical strengths
Our products use power controller ICs developed through in-house collaboration.
While working on differentiation, including high efficiency and low standby power, we are also working to reduce resource consumption through miniaturization.
Management of Environmental Impact Materials Included in Products
The MinebeaMitsumi Group has issued the standards and regulations on chemical substances in products requiring suppliers to supply products (raw materials and parts) free of hazardous substances along with data and documentation verifying their products' safety. We also conduct our own verification tests of suppliers' products using XRF (X-ray fluorescence spectrometers) to ensure the products are free of hazardous materials subject to RoHS regulations.
Management methods for chemical substances contained in products
- Note 1. (M)SDS ((Material) Safety Data Sheet):
A data sheet covering information required for safe handling of chemical substances (ingredients, characteristics, handling methods, and emergency coping methods). - Note 2. ChemSHERPA: A data sheet recommended by JAMP (Joint Article Management Promotion Consortium) to communicate information of toxic chemicals incorporated in chemical substances and compounds.
Future Issues and Goals
We will continue to engage in technological development and expand "Beyond Zero," which refers "the volume of avoided CO2 emissions by our products that exceeds our own emission."
