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 2022 were as follows:
Environmental Preservation Investments (Non-consolidated)
In fiscal 2015, MGC began undertaking environmental preservation investments.
These investments include investment items that, although they may be very effective in reducing environmental loads, 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.
For example, by replacing mercury lamps and fluorescent lights with LED bulbs, it is possible to both save energy and reduce mercury-containing equipment. Replacing air conditioning equipment with energy-saving models has the dual effect of conserving energy and reducing CFCs (thus preventing destruction of the ozone layer). Further, replacing the equipment with air conditioners that do not use freon as a refrigerant can obtain the additional effect of reducing greenhouse gases.
In fiscal 2022, MGC installed solar power generating facilities on the new R&D building, saved energy and reduced mercury usage by replacing mercury lamps with LEDs, and took other measures. These steps had the effect of reducing GHGs by about 118 t-CO2/year on a pro forma basis.
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 2022 was approximately 1.5 billion yen. The main investments were R&D investment relating to circular carbon methanol (CCM) production and updating compressors at the Yokkaichi Plant.
- Expenses
Total expenses related to environmental conservation activities in fiscal 2022 were approximately 11.5 billion yen. Of these, the highest expense was about 4.1 billion yen for research and development, accounting for around 36% 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.
