Voluntary Initiatives to Reduce Atmospheric Emissions of Chemical Substances

Materiality Focus

As a corporate group that does business in the chemicals sector, the Toray Group places the highest priority on reducing emissions of chemicals into the atmosphere in order to reduce its environmental impact.

Under the Fifth Medium-Term Environmental Plan, which covered fiscal 2016–2020, the Group works to achieve its targets for reducing atmospheric emissions of volatile organic compounds (VOCs) and substances specified under Japan's Pollutant Release and Transfer Register Law (PRTR Law).

Reducing Atmospheric Emissions of PRTR Law-Specified Substances

In fiscal 2016, the Toray Group's atmospheric emissions of PRTR Law-specified substances were 752 tons, which represented a 71% reduction compared to the base year of fiscal 2000. The Group achieved the target of a 70% reduction compared with the base year under the Fifth Medium-Term Environmental Plan.
The main improvement in fiscal 2016 was achieving proper adsorption and recovery of waste gases at Toray's Chiba Plant, which reduced nine tons of atmospheric emissions of PRTR substances. Additionally, the former Toray Battery Separator Film Co., Ltd. reduced 33 tons of atmospheric emissions in fiscal 2016 by strengthening activated carbon adsorption recovery.

Note: The fiscal 2020 target for the absolute volume of emissions was revised using a new base value. This base value is based on emissions from the 2000 base year, to which Group company emissions in fiscal 2016 (353 tons) were added, which the Group began tracking in fiscal 2016.
