Reducing Chemical Substance Emissions

Each MGC Group company assesses and submits notifications on substances subject to the chemical substance emission notification system of the country in which it is based (PRTR in Japan), while working to reduce the amounts released and transferred.

Substances Subject to Notification under the PRTR Law (MGC Group)

Many countries have systems that require notifications regarding chemical substance emission in a similar way to Japan's PRTR Law (TRI in the US, etc.). In its tabulation, MGC has aggregated substance emissions reported by MGC alone and by domestic MGC Group companies based on the PRTR Law, and emissions reported by overseas group companies under the laws of their respective countries and regions for substances listed under Japan’s PRTR system or for which there is a CAS number.

Japan Chemical Industry Association PRTR-targeted Substances (MGC Alone)

The Japan Chemical Industry Association (JCIA), of which MGC is a member, has specified 328 Class I Designated Chemical Substances stipulated by the PRTR Law, and a JCIA-specified 90 substance plus 1 substance group as voluntary PRTR-targeted substances considered volatile organic compounds (VOCs). The JCIA tabulates the emissions of member companies, and the entire chemical industry is working toward reducing emissions of these PRTR substances.
The amount of said substances emitted by MGC in fiscal 2018 totaled 72 substances and 326 tons. The production volumes of some products increased, and as a result, emissions increased slightly from the previous fiscal year. MGC will continue its efforts to reduce emissions occurring in conjunction with facility shutdowns by implementing measures to reduce problems at plants and taking other action.
