Resource input and emissions (FY2025)
Pollutant Release and Transfer Register (PRTR): a system where businesses track and report to the government the amounts of various hazardous chemicals released into the environment (air, water, soil) from their facilities, as well as the amounts transferred offsite as waste. The government then estimates and publishes the total release and transfer amounts based on these reports.
sulfur hexafluoride (SF6): a greenhouse gas with a global warming potential estimated to be 22,800 times that of CO2.

Emissions data by plant
“Water quality”
Units: pH (none), E. coli (cells/cc), dioxins (pg-TEQ/l), others (mg/l), { } (daily average), ― (not set), ND (below detection limit)
Regulatory limit: the strictest values specified in the environmental laws/regulations, ordinances and agreements
If measured only once, the value is listed in the “maximum” column.
For the following regulated items, values were below the limit of quantification (not detected) at all plants
Phenols, all chromes, all cyanides, hexavalent chromium, cadmium, lead, all mercuries, alkyl mercury, arsenic, organic phosphorus, PCB, trichloroethylene, tetrachloroethylene, dichloromethane, carbon tetrachloride, 1,2-dichloroethane, 1,1-dichloroethylene, cis-1,2-dichloroethylene, 1,1,1-trichloroethane, 1,1,2-trichloroethane, 1,3-dichloropropene, thiuram, simazine, thiobencarb, benzene, selenium
“Atmosphere”
Units: particulates (g/Nm3), NOx (ppm), SOx (k value), hydrogen chloride (mg/Nm3), dioxins (ng-TEQ/Nm3)
Regulatory limit: the strictest values specified in the environmental laws/regulations, ordinances and agreements
Measured value: the maximum value recorded (if multiple facilities exist, the value for the facility with the most stringent regulatory limit is presented)
“PRTR act handling volume and emission/transfer volume”
Unit: kg/year, except for dioxins (mg-TEQ/year)
Handling volume: excludes volumes below 1000kg/year (500 kg/year for specified Class 1 substances)
