Activities that mitigate climate change at business site

Energy-saving activities To reduce emissions of CO2 and other greenhouse gases from our operations, MHI Group conducts a range of activities to conserve and raise the efficiency of energy at each site, including the shift to LED lighting and highly energy-efficient substation equipment.
Introduction of Renewable Energy MHI Group, at some of its business sites, works to reduce emissions of CO2 and other greenhouse gases by shifting to renewable energy and using electricity. Each site has installed photovoltaic (PV) systems and purchases electricity generated through hydroelectric power. In March 2018 PV systems were installed on the rooftop of the Thailand plant of Mitsubishi Turbocharger Asia Co., Ltd, reducing annual CO2 emissions by nearly 3,000 tons, for which the company received high acclaim from the Thai government as it contributed to the country’s reduction of CO2 emissions.
Furthermore, the electricity generated by the White Deer Wind Farm operated by the Group is used by Group companies in the United States through Renewable Energy Certificates (RECs), and is reducing CO2 emissions by about 40,000 tons per year.

Products and technologies that mitigate climate change

Products and technologies that mitigate climate change and reduction in CO2 from using 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 efficiency of the transportation sector; and high energy-saving air-conditioning systems that use heat pump technology. In fiscal 2020, through the reduction in CO2 from using MHI Group’s main products (Note) came to about 49,130 thousand tons.
  • Base lines were determined (base year/comparison target) in accordance with the characteristics of each product. Using these base lines, the amount of CO2 reduced through product use was calculated in accordance with such factors as the number of products in operation and the number of units sold in the relevant fiscal year.
