We are working to reduce emissions of hazardous chemical substances through ongoing efforts to prevent leaks of such substances and the transition to processes that create less emissions.

In fiscal 2021, our hazardous chemical substance emissions increased 12% compared with the previous fiscal year, to 741 tons, due to such factors as problems with capturing emissions from certain processes and the recovery in production activities from the impact of the COVID-19 pandemic, amounting to a worsening of 1% in per sales unit compared with the previous fiscal year. However, this result still constituted a 15% improvement compared with fiscal 2019, prior to the pandemic.

Top 10 chemical substance emissions

NOx emissions resulting from fuel use were up 6% from the previous year at 1.20 thousand tons, while SOx emissions generated in the same manner were up 5% from the previous year at 2.34 thousand tons.
Further, emissions of volatile organic compounds (VOC) decreased by 8% from the previous year to 1.34 thousand tons.

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.
