Chemical Substance Control
Reducing Chemical Substance Emissions
Since FY1995, we have participated in the voluntary PRTR* survey conducted by the Japan Chemical Industry Association (JCIA) in an effort to reduce emissions of chemical substances into the environment.
Although the revised PRTR Law came into effect in April 2023 and significantly increased the number of substances subject to the Law, the Medium-term RC Basic Plan 2027 sets a new target for emissions of PRTR-regulated substances at 83 t/y or less, which is lower than the target in the previous plan.
Our emissions were 75.9 t/y in FY2025, achieving the target. We will continue working toward systematic reductions.
- PRTR (Pollutant Release and Transfer Register): A system under which business operators report releases of chemical substances to air, water, and soil and transfers in waste to government authorities, which compile and publish the data.
