FY3/2024 Environmental Data
Environmental Impact of MinebeaMitsumi Group
The Group has 130 production and R&D sites and 101 sales offices in 28 countries around the world. We produce and sell a diverse range of products including bearings (our main product), machined components, electronic devices, and semiconductor products and so on.
The Group's environmental impact for FY3/2024 is summarized below.
Input and Output (FY3/2024 Actual)
- LPG: Liquefied petroleum gas
- PRTR chemicals: Chemical substances reported to the administration according to the PRTR Law. (Japanese Domestic Law)
- GHG(CO2 equivalent): Greenhouse gases converted to CO2 amounts using the global warming potential. (CH4, HFC, PFC, SF6, NF3, N2O)
- NOx: Nitrogen oxides. Causative agent of photochemical smog and acid rain.
- SOx: Sulfur oxides. Causative agent of asthma and acid rain.
- Particulates: Microscopic solid matter contained in exhaust gas generated through combustion. Larger particles reduce visibility, while smaller particles are respiratory organs and other health impacting substance.
- Waste: valuables and wastes
- COD: Chemical oxygen demand. An indicator used for environmental standards for organic matter in marine areas and lakes.
- BOD: Biochemical oxygen demand. An indicator used in environmental standards for organic matter in rivers.
- SS: Suspended solids in water. An indicator used for the turbidity of water used in environmental standards for insoluble substances in water.
Greenhouse Gas Emissions of MinebeaMitsumi Group
CO2 equivalent emissions of greenhouse gases (Total and Per Basic Sales Unit)
* Changed the Scope2 calculation method from location-based to market-based, retroactively up to the fiscal year ended March 2020
For the fiscal year ended March 2024, the Group's overall greenhouse gas emissions were 868,140 tons of CO2 equivalent, an increase of 0.8% from the previous fiscal year. Despite an 8.5% increase in sales, the increase was limited by a lower CO2 emission coefficient for electricity, improved production efficiency, and the introduction of renewable energy.
Greenhouse gas emissions per unit of sales were 0.619 tons per million yen, a 7.2% decrease compared to the previous fiscal year, as the rate of increase in CO2-equivalent emissions was less than the rate of increase in sales.

Results of FY3/2024 Initiatives
For the fiscal year ended March 2024, 122,978 tons of steel and 37,393 tons of resin were used, and the total amount an increase of 6.3% compared with the previous year as sales increased.
The amount of "Transported outside the company as waste" totaled 109,183 tons, an increase of 3.0% from the previous year. In addition, the amount of sludge for "Disposed of as landfill" improved by more than 1,000 tons from the previous fiscal year (FY2023/3: 5,135ton), the main reason for this was that sludge that had previously been directly landfilled at the plant in Thailand was able to be converted to incineration.
