Prevention of Pollution


MC recognizes the importance of striving to create and enhance environmental value, as stated in the Environmental Charter, by undertaking conservation activities and reducing our environmental footprint, including through the prevention of pollution. Moreover, in terms of company-wide management of compliance with environmental laws, regulations, etc., MC takes responsibility as a business that produces waste. To ensure rigorous compliance with laws and regulations related to preventing pollution as well as the reduction, reuse and recycling of waste within MC, internal notifications are sent out, as well as announcements and alerts about meetings and other related events. Furthermore, MC has formulated guidelines and standards for responding to oil spills and soil contamination and disseminates this information internally to ensure thorough understanding.

Risk Management

When reviewing and making decisions on loan and investment proposals, MC conducts a comprehensive screening process which considers not only economic aspects, but ESG factors including pollution prevention as well as the reduction, reuse and recycling of waste. Besides screening new investment and exit proposals, MC also strives to make improvements to existing business investments by monitoring their management practices. Regarding oil spills in particular, oil spill risk surveys are conducted regularly, confirmations are made that oil spill accident prevention and risk management frameworks have been established, and training is conducted to ensure the thorough dissemination of information on these topics. Through these measures, MC is ensuring appropriate risk management to prevent oil spills from occurring.

Initiatives to Reduce Waste Production (Mitsubishi Shokuhin Co., Ltd.)

MC subsidiary Mitsubishi Shokuhin Co., Ltd. carries out various efficiency measures to optimize its supply chains through collaboration between the manufacturing, distribution and retail sectors. Working jointly with manufacturers and retailers to enhance logistics efficiency and collaborating with retailers to reduce product return rates and optimize inventory have led to reductions in greenhouse gas emissions and waste production.

Application of Life Cycle Analysis in our Salmon Farming Business

Cermaq, an MC subsidiary, uses life cycle assessments (LCAs) for the fish feed management over the two-year salmon maturation process in order to reduce environmental impacts including waste and CO₂ emissions. This is important since fish feed has been identified as an important contributor to resource use and emissions related to the production of salmonids in net-pen systems. By conducting research on optimal feed ingredients and methods during the planning stage, Cermaq is proactively seeking improvements and identifying efficient feeding methods in its operations. One example of ongoing projects on fish feed is research conducted at the Arctic Salmon Research Centre, where Cermaq is a partner, doing research on optimal feed for salmon farming in the Arctic environment in Northern Norway.
