Mitsui & Co.’s Materiality 2015-2018

Protection of the Global Environment

Recognition of societal issues

As a corporation that operates across countries and regions around the world, we recognize that impact on the global environment has the potential to risk the sustainable growth of society and our company. In relation to climate change mainly caused by greenhouse gas emissions, corporate response plays a particularly crucial role in efforts to build a sustainable society. In recent years, this has been shown by the adoption of the Paris Agreement under the United Nations Framework Convention on Climate Change, as well as by the formulation of the Taskforce on Climate-related Financial Disclosures (TCFD) guidelines. At the same time, we recognize that responding to climate change also brings new business opportunities, including low-carbon energy, environmentally-friendly infrastructure and products, and innovative services that utilize digital technology.

  • Global warming, climate change
  • Loss of biodiversity
  • Energy and water shortage
  • Environmental pollution

Main risks and opportunities


Risks arising from policies and legal systems related to the transition to a low-carbon economy, and risks to supply and demand in existing business resulting from the creation of new technologies and new markets; risks to companies' operations from cyclones and hurricanes caused by the physical effects of climate change, and risks to production volumes for agriculture, forestry, and fishery products from abnormal weather (high temperatures/drought); and higher environmental costs resulting from ecosystem destruction, degradation, etc., as a consequence of business activities. We assess these climate change related risks for more than six years, with a long-term perspective.


Expansion of environment–related markets due to increased environmental awareness and the tightening of regulations; demand for high-efficiency power plants; creation of new business models through the circular economy and sharing; expansion of business domains as a result of energy diversification, such as sustainable energy; and handling of products and services that contribute to a low-carbon society by controlling energy consumption and greenhouse gas emissions.


Mitsui’s Approach

We rigorously comply with environment-related laws, regulations, and treaties. We strive to prevent environmental pollution and curb greenhouse gas emissions, to adapt to climate change, and to maintain biodiversity. We are alert to environmental impacts and work to mitigate those impacts. We use our integrated strengths and work in cooperation with our partners to achieve rational, long-term industrial solutions to environmental problems. We systematically provide grants, through the Mitsui & Co. Environment Fund, for university research and NPO/NGO activities that contribute to the solution of environmental problems, efficient resource utilization, protection of ecosystems, and harmonious coexistence between ecosystems and human beings.
