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

Emissions of hazardous chemical substances in FY2019 decreased by 11% from FY2018 due to the strengthening of measures, and the per sales unit improved by 7% compared to 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 was 1.75 thousand tons. The reduction rate compared to FY1998 became 81%, and the target was achieved.

Emissions of hazardous chemical substances in FY2017 and FY2018 increased including due to business expansion, but in FY2019 we actively ensured compliance with various regulations and worked to improve the yield in processes using hazardous chemical substances.

  • *1Among the class 1 designated chemical substances under the Law Concerning Reporting, etc. of Releases to the Environment of Specific Chemical Substances and Promoting Improvements in Their Management and chemical substances indicated by the Japan Chemical Industry Association, chemical substances harmful to aquatic environments and the ozone layer are subject to the calculation of atmospheric, water, and soil emissions.
  • *2The total amount of emissions into the atmosphere, water, soil, and landfill for a total of 567 chemical substances including Class I chemical substances listed in the Chemical Substances Management Law (462 substances: revised April 2010) and chemical substances (105 substances) voluntarily assessed by the Japan Chemical Industry Association (JCIA).

Trends in emissions of hazardous chemical substances and emissions per sales unit

  • *Among the class 1 designated chemical substances under the Law Concerning Reporting, etc. of Releases to the Environment of Specific Chemical Substances and Promoting Improvements in Their Management and chemical substances indicated by the Japan Chemical Industry Association, chemical substances harmful to aquatic environments and the ozone layer are subject to the calculation of atmospheric, water, and soil emissions.

The breakdown of emissions of chemical substances into the environment in FY2019 was 98.5% for emissions into the atmosphere, and 1.5% for emissions into water, and there were no emissions for soil or landfills.

Further, emissions of volatile organic compounds (VOC) decreased by 16% from FY2018 to 1.66 thousand tons due to decreased production volume.

Trends in chemical substance emissions

  • For emissions of Class 1 chemical substances listed in the Chemical Substances Management Law and chemical substances designated by the Japan Chemical Industry Association, the figures shown are the total of emissions into the atmosphere, soil, and water, and landfill amounts within business sites.

Impact on Atmosphere

SOx emissions resulting from fuel use were 2.5 thousand tons (a 1% increase from FY2018). NOx emissions generated in the same manner were 1.5 thousand tons (a 6% decrease from FY2018).

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.
