Chemical Substance Control
Reducing chemical substance emissions
Since FY1995, we have participated in the voluntary PRTR investigations conducted by the JCIA in an effort to reduce emissions of chemical substances into the environment.
Our emissions of PRTR substances in FY2022 was 81 tons, a 24.6% reduction from the level in FY2015.
We will continue to strive to systematically reduce chemical substance emissions toward the FY2024 objective of 25% reduction from the level in FY2015.
