Production-related Input and Output (MGC non-consolidated and domestic MGC Group companies)
Primary production-related inputs and outputs for the non-consolidated MGC and domestic MGC Group in fiscal 2023 were as follows:
Environmental Preservation Investments (Non-consolidated)
MGC began undertaking environmental preservation investments in fiscal 2015, and it has continued these investments for ten years as of fiscal 2024.
These investments include investment items that, although they may be very effective in reducing environmental load, may be less likely to be adopted due to long payback periods or for other reasons, as well as investment items that lead to preservation of biodiversity, recruited through proposals from the various MGC sites. A secretariat consisting of the Environment, Safety and Quality Assurance Division and the Production Technology Division at corporate headquarters then select the items to implement and secure the required budget, before executing the investment.
The measures taken in the last ten years include the non-use of specified chlorofluorocarbons by replacing refrigeration equipment used in manufacturing, the reduction of power consumption by introducing inverter controlled rotating equipment, power saving by using thermal barrier coatings on buildings and thermal barrier films attached to windows and the improvement of work environments, the replacement of air-conditioning systems with energy-efficient systems, and the replacement of fluorescent lights and mercury lamps with LED lights to avoid the use of mercury and save energy.
With a cumulative investment of approx. 1.3 billion yen over the ten years, a reduction of a total of about 8,400 t-CO2e in greenhouse gas emissions was achieved.
MGC will continue to invest to reduce environmental impact.
Environmental Accounting (Non-consolidated)
Through environmental accounting in accordance with guidelines by the Ministry of the Environment, MGC has quantitatively calculated and released the investment amount and costs of environmental preservation required for the business activities of non-consolidated, as well as the real economic benefits obtained.
- Investment amount
The total amount of investment related to environmental preservation activities in fiscal 2024 was approximately 1.1 billion yen. The main investments were R&D investment relating to gas barrier materials and circular carbon methanol (CCM) production.
- Expenses
Total expenses related to environmental conservation activities in fiscal 2024 were approximately 11 billion yen. Of these, the highest expense was about 2.9 billion yen for R&D cost, accounting for around 27% of the total.
- Economic benefits
The reduction of expenses through energy saving measures and the income from the sale of unneeded items generated in our business activities were recorded as real economic benefit.
