We are working to reduce hazardous chemical substance emissions through ongoing efforts to prevent leaks and transition to processes that create fewer emissions. In FY2024, due to those efforts in the carbon fibers and resin and plastic processing businesses, our hazardous chemical substance emissions were 435 tons, and emissions per sales unit was 51.7kg/100 million yen.
