The MMI Beyond Zero initiative
Our "MMI Beyond Zero" initiative aims to contribute to the reduction of global CO2 emissions by enhancing the energysaving features of our products. By using these products, our customers will in turn reduce the electricity consumed by their products, and their customers' products.
Calculation method
The volume of avoided CO2 emissions is calculated based on the Japan Electronics and Information Technology Industries Association (JEITA) guidelines. "Effect on reduction of electricity consumption at the time of product use" 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.
Formula used to calculate 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
The result for the fiscal year ended March 2022 was approximately 2,490,000 t-CO2, (up 42% year on year). This was a remarkable result, surpassing in just one year our initial target of approximately 2,300,000 t-CO2, a 30% increase in contribution, by the fiscal year ending March 2031. This was mainly due to an increase in sales of existing products and the launch of new products. We will continue to contribute to reducing global CO2 emissions through the development and promotion of products with advanced energy-saving features.
Fan motor bearings
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.
Polygon mirror scanner motors
These motors are used in laser writing in digital copiers and other such devices. A polygon mirror is rotated at high speed to scan a laser beam radiated from an laser diode (LD) into a photoreceptor. High-precision fluid bearing technology helps make equipment quieter and save both space and energy.
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.
