Environmental accounting

Environmental protection costs

In FY 2022, Mizuno’s environmental protection costs have an increase of approximately 80 million yen from the previous year, bringing the total investment to 182.8 million yen. The expenses increased by 20 million yen from the previous year, amounting to 162.21 million yen. Just as in the previous fiscal year, the FY 2022 investments were mainly made in installing LED lights and switching to energy-saving air conditioners. The environmental protection expenses primarily comprised the cost of research and development in materials and processes that would help reduce the environmental impact of manufacturing processes and that of managing EMS activities.
