Mitsui & Co.’s Materiality

Create an eco-friendly society

Accelerate initiatives towards environmental issues, such as responding to climate change and water resource problems, and contributing to a circular economy.

Recognition of Societal Issues

As a company with business operations in countries and regions worldwide, Mitsui & Co. recognizes that climate change and other impacts on the global environment could cause significant risks to the sustainable growth of society and Mitsui itself. In recent years, the response of business corporations to climate change has become increasingly important in terms of the sustainability of society, especially since the adoption of the Paris Agreement by the United Nations. We also recognize that the response to climate change will create new business opportunities due to the accelerating shift to energy conservation, renewable energy, EV/new technologies/new materials/multi-materials in the mobility field, and innovative services based on digital technology. Other priorities for Mitsui include the effective utilization of water resources, the management of forest resources, biodiversity, resource recycling, and the circular economy.

  • Global warming, climate change
  • Water resource shortages
  • Resource recycling, the circular economy
  • Environmental pollution
  • Loss of biodiversity

Major Risks and Opportunities

  • Impact of new technologies and the creation of new markets on supply and demand in existing business areas
  • Disruption of business operations due to the impact of cyclones, hurricanes, and other events linked to climate change
  • Impacts on the natural environment, such as the large-scale use of water in business operations
  • Impact of leakage of hazardous chemicals
