Chemical Substance Control
Reducing Chemical Substance Emissions
Since FY1995, we have participated in the voluntary PRTR* investigations conducted by the Japan Chemical Industry Association (JCIA) in an effort to reduce emissions of chemical substances into the environment.
The reduction target during the period of the 11th (FY2022–FY2024) Medium-term RC Basic Plan was 81 t/y or less for FY2024. However, the target was revised to 99 t/y or less because the PRTR Law was revised in April 2023 and the number of applicable designated chemical substances greatly increased. We achieved our emission target of 84.9 t/y in FY2024 and we will continue working toward systematic reductions.
* PRTR (Pollutant Release and Transfer Register): A system for registering the discharge and movement of pollutants. Under the system, operators report the release of chemical substances into the air, water, and soil and transfer of waste to government agencies that gather, organize, and publish the data.
