Chemical Emission Reduction
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)
- High-emission Substances Notified under the PRTR Law (Non-consolidated MGC and Domestic MGC Group)
- Japan Chemical Industry Association PRTR-targeted Substances (Non-consolidated)
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 the non-consolidated MGC 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.

High-emission Substances Notified under the PRTR Law (Non-consolidated MGC and Domestic MGC Group)
Among the substances notified under the PRTR Law, those listed below were emitted by the non-consolidated MGC and domestic MGC Group in total in amounts of 10 tons or more.
| Government-designated number | Substance | Emissions (tons) | ||||
|---|---|---|---|---|---|---|
| FY 2016 | FY 2017 | FY 2018 | FY 2019 | FY 2020 | ||
| 128 | Chloromethane | 534 | 567 | 590 | 308 | 187 |
| 296 | 1,2,4-Trimethylbenzene | 75 | 99 | 113 | 162 | 162 |
| 186 | Dichloromethane | 58 | 78 | 87 | 74 | 78 |
| 300 | Toluene | 13 | 14 | 12 | 14 | 14 |
| 80 | Xylene | 18 | 24 | 17 | 20 | 11 |
Japan Chemical Industry Association PRTR-targeted Substances (Non-consolidated)
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 2020 totaled 71 substances and 351 tons, a decrease of around 9% from the 387 tons* of emissions in fiscal 2019. This was due to resolutions of issues associated with exhaust gas recovery equipment in fiscal 2019.
MGC will continue its efforts to reduce emissions of chemical substances occurring in conjunction with shutdown of equipments and similar factors, by implementing measures to reduce problems at manufacturing plants and through preventive measures.
