Reducing Hazardous Substance Emissions
We are working to systematically reduce emissions of hazardous chemical substances associated with our business activities and committ to preventing environmental pollution.
Reducing Emissions of Hazardous Chemical Substances*1
So far, the Teijin Group has been engaged in the reduction of hazardous chemical substances with the goal of achieving its targets by FY2020. In FY2019, the Group set new targets for FY2030 and launched initiatives for achieving them.
The Group’s targets (KPIs) for FY2030
By 2030, improve the hazardous chemical substances emissions per sales unit by 20% compared to FY2018
In addition to steadily responding to various regulations, we are striving to improve yield rate within processes that use hazardous chemical substances. There were no violations of the various regulations at the Teijin Group in FY2020. We established measures to reduce and prevent leaks of hazardous chemical substances in each business, including the carbon fibers and resin and plastic processing businesses. As a result of these measures, as well as the impact of the COVID-19 pandemic, our hazardous chemical substance emissions decreased 18% compared with the previous year, to 660 tons, making for a 22% improvement per sales unit compared with FY2018.
By FY2020, with regard to emissions of chemical substances into the environment*2, for which the target was to reduce by 80% or more by FY2020 compared to FY1998, the amount for FY2020 was 1.51 thousand tons, a 14% decrease from the previous year, with the reduction rate compared to FY1998 at 81%, and the targets being achieved. The breakdown of emissions of chemical substances into the environment in FY2020 was 98.5% for emissions into the atmosphere, and 1.5% for emissions into water, and there were no emissions for soil or landfills.

Impact on Atmosphere
NOx emissions resulting from fuel use were down 26% from the previous year at 1.14 thousand tons, while SOx emissions generated in the same manner were down 10% from the previous year at 2.24 thousand tons. Further, emissions of volatile organic compounds (VOC) decreased by 13% from the previous year to 1.46 thousand tons.

Preventing Soil / Groundwater Pollution
In addition to conforming to each country’s and territory’s legislation relating to the prevention of soil pollution, the Teijin Group formulated guidelines for preventing soil and groundwater pollution. Under these guidelines, we are striving to prevent soil and groundwater pollution resulting from our business operations.
