Environmental Impact of MinebeaMitsumi Group
The Group has 129 production and R&D sites and 100 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 the fiscal year ending March 2025 is as follows.
Input and Output (FY3/2025 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)
* Scope2 : Market-based
For the fiscal year ended March 2025, the Group's overall greenhouse gas emissions were 789,768 tons of CO2 equivalent, a decrease of 9.0% from the previous fiscal year. Sales decreased compared to an increase of 8.6% due to improved production efficiency and the introduction of renewable energy.
Greenhouse gas emissions per unit of sales were 0.519 tons per million yen, a 16.2% 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.
