Note: PRTR law specifies amounts in kilograms with fractions to 2 significant digits; however, values above are in tons.
0.0 means less than 0.005 tons.
Units of dioxins are mg-TEQ.

Reduction of Hazardous Chemical Substance Emissions into the Atmosphere

We are promoting the systematic reduction of emissions of butadiene and acrylonitrile, which are among the substances requiring priority action (priority substance) stipulated by Japan's Air Pollution Control Law. We have already reduced butadiene to less than five tons a year. We plan to proactively invest in facilities and equipment for the reduction of acrylonitrile in the future.
