Climate Change

Climate change governance

Committee MHI Group Environment Committee
Risk management measures At MHI, the Environment Committee chaired by the Chief Technology Officer, is the Committee with the chief responsibility for matters concerning climate change. In fiscal 2016, the Environmental Planning Group at MHI Headquarters served as the Secretariat. The managers of individual divisions assess climate change risk and other forms of environmental risk using benchmarks for the scale of impact on business operations and society, and the urgency of risk countermeasures. Significant risks are relayed through Environmental Planning Group channels to the Environment Committee, which then deliberates on countermeasures. Especially serious risks are reported to the Executive Committee headed by the Company President. The Executive Committee then explores reported risks and implements Companywide measures against those deemed important. These risks will be proposed to the Board of Directors for deliberation when members of the Board of Directors present at the Executive Committee deem it important to do so.
Recommendations for policies related to climate change In order to maximize efforts to combat climate change, MHI Group makes policy recommendations through the Japan Busuiness Federation.
Incentives toward management activities related to the issue of climate change In fiscal 2017, as part of its Group-wide award system, the MHI Group established the Best Environmental Product Award and the Best Environmental Practices Award as categories in its annual Best Innovation Awards. Winners receive awards amounting to hundreds of thousands of yen. In fiscal 2017 we granted Best Environmental Product awards to people responsible for three products: a CO2 recovery plant featuring the world's largest processing capacity; an energy-independent sewage-sludge incinerator; and a centrifugal chiller using a low-GWP refrigerant. The Best Environmental Practices Award, recognizes business practices that reduce environmental impact. This award was given to members responsible for constructing a business model with partner companies to recycle carbon fiber reinforced polymers (CFRP) used in aircraft, which were previously considered difficult to recycle.
CDP submission We have submitted a CDP response since fiscal 2004, and the evaluation of fiscal 2017 was B.

Climate change opportunities and risks

Climate change opportunities Implementation of the Paris Agreement is expected to spur global growth in the demand for highly effcient natural gas-fired power generation as a step toward the creation of a low-carbon society. MHI Group has developed and begun supplying power-generating plants powered by high-effciency gas turbines as well as systems for the recovery of CO2 from power plant exhaust gases. The Group considers emissions regulations overseas to be a significant business opportunity.
Energy-saving activities MHI Group conducts a variety of energy-saving activities at each site, including the use of LED lighting and highly energy efficient substation equipment, and is working to improve energy-saving and energy efficiency.

Products and technologies that mitigate climate change

Products and technologies that mitigate climate change and CO2 reductions through the use of MHI Group products MHI Group is working to create a low-carbon society across a broad spectrum of fields, including large-scale power generation technologies such as highly efficient thermal power generation plants and nuclear power plants; power generation systems that utilize wind, geothermal, and other renewable energies; ships and transportation systems for improving the effciency of the transportation sector; and high energy-saving air-conditioning systems that use heat pump technology. In fiscal 2017, through the use of MHI Group's main products, CO2 reductions came to about 49.8 million tons from the fiscal 1990 level.
