Summary of MGC and the MGC Group's environmental and social activities in fiscal 2020




Environmental Performance
(Environmental Preservation Performance Metrics)

Environmental Management

  • ISO 14001 certification status

    MGC has obtained certification of compliance with the ISO 14001 environmental management system standard at all of its domestic plants and endeavors to continuously improve its environmental performance.

  • Environmental risk management

    For environmental risk management, MGC requires safety assessments to be performed before installation, replacement, expansion or major modification of facilities. At existing facilities, MGC pursues prevention or early detection of abnormalities through routine inspections and maintenance and conducts emergency response drills as an added precaution against accidents. It has a wide range of insurance coverage, including fire insurance, business interruption insurance, oil pollution insurance and liability insurance.

  • Water risk management

    MGC monitors its actual water consumption and uses water efficiently by measuring water withdrawal, water discharge, water usage and water recycling. In drawing from water sources, MGC restricts its intake to permitted quantities in accord with applicable laws or agreements with municipalities. Additionally, MGC discharges wastewater into rivers, the sea or other public water bodies in compliance with effluent standards after treating it to filter out identified pollutants.

  • Internal carbon pricing

    In April 2021, MGC adopted an internal carbon pricing scheme to quantify climate-change risks. When planning capital expenditures that would result in increased or reduced CO2 emissions, MGC factors into its investment decisions a cost or benefit based on an internal carbon price (¥10,000/Mt Co2e). By doing so, it promotes reduction of CO2 emissions and development of technologies and products that contribute to building a low-carbon society.

  • Biodiversity conservation

    MGC endeavors to reliably manage chemicals based on Responsible Care®, mitigate climate change by improving energy efficiency and reducing GHG emissions and maintain a richly biodiverse natural environment. MGC also contributes to sustainable development by creating environmentally beneficial technologies and products and promoting their widespread adoption.

  • Renewable energy use

    • MGC has been involved in geothermal power generation since 1990. A joint venture co-owned by MGC constructed the Wasabizawa Geothermal Power Plant and has been operating it since April 2019. In August 2019, a second joint venture co-owned by MGC commenced construction on another geothermal power plant in Appi, Iwate Prefecture, scheduled to be commissioned into operation in April 2024.
    • Additionally, MGC's QOL Innovation Center Shirakawa (Fukushima Prefecture) and Niigata Research Laboratory (Niigata Prefecture) are equipped with photovoltaic systems that generate power for on-site consumption.

  • Basic approach to wages and working hours

    The MGC Group complies with local minimum wage laws and regulations in the countries/regions in which it operates and pays wages to its employees based on fair evaluations. In addition to also complying with local laws and regulations on working hours, the Group endeavors to enable employees to have a healthy work-life balance through appropriate labor management to avoid onerous work schedules.


  • Approach to promoting workforce diversity

    MGC values diversity and will endeavor to create an environment in which employees with diverse attributes can give full play to their respective capabilities, work with a sense of purpose and derive fulfillment from their jobs. MGC has endorsed the Japan Business Federation's "30% by 2030 Challenge," which aims to increase women's representation in the labor force. Toward this end, MGC will further step up initiatives that capitalize on the perspectives of diverse individuals, particularly women, in pursuit of sustained growth.

  • Diversity promotion plan

    To promote better career opportunities for women, MGC has formulated an action plan that extends through fiscal 2021. Under the plan, MGC is providing support to help women advance in their careers and augmenting programs that support a healthy work-life balance in the aim of quadrupling the percentage of management positions held by women (relative to fiscal 2015). Additionally, MGC will continue to offer additional accommodations to facilitate diverse work modalities in accord with the Act on Advancement of Measures to Support Raising Next-Generation Children and Act on Promotion of Women's Participation and Advancement in the Workplace.
