We are working to reduce hazardous chemical substance emissions through ongoing efforts to prevent leaks and transition to processes that create fewer emissions. In FY2023, due to those efforts in the carbon fibers and resin and plastic processing businesses, our hazardous chemical substance emissions decreased by 17% compared with the previous fiscal year, reaching 656 tons. This represents a 37% improvement in emissions per sales unit compared with FY2018.

Trends in hazardous chemical substance emissions and emissions per sales unit

• *Among the Class 1 designated chemical substances under the Act on Confirmation, etc. of Release Amounts of Specific Chemical Substances in the Environment and Promotion of Improvements to the Management Thereof and chemical substances indicated by the Japan Chemical Industry Association, chemical substances emissions to atmosphere, water, and soil which are harmful to aquatic environments and the ozone layer in the Globally Harmonized System of Classification and Labelling of Chemicals (GHS) classification defined by the United Nations (UN) are subject to the calculation for emissions.
• *Per sales units are calculated using consolidated net sales as the denominator.
