Approach to Environmental Risk and Opportunities

Understanding of the External Environment

In Mizuho's Policies for Environmental Initiatives, environmental initiatives are an essential condition for corporate existence and business activities. Moreover, Mizuho is aware that these initiatives have risks and opportunities. Therefore, based on a precautionary approach toward addressing climate change issues, building a low–carbon society, promoting the sound material cycle, preserving biodiversity, and other issues, Mizuho has determined it will take voluntary and proactive initiatives.

Under the "Sustainable Development Guidelines" (SDGs) of the United Nations and the Paris Agreement, which provides a new framework for addressing climate change, "common global objectives" have been set aimed at attaining sustainable development of society. Along with this, companies are expected to play a role in solving these environmental and social issues, including climate change issues.

In addition, financial authorities, institutional investors, and other parties in major industrial nations have become increasingly aware of the impact that climate change has on business (company risks, opportunities, and actions in response). In conjunction with this, the Financial Stability Board established the "Task Force on Climate–related Financial Disclosures (TCFD), and in June 2017 the TCFD submitted a report offering opinions concerning the disclosure of climate–related financial information.

Mizuho recognizes the impact that climate change and other environmental issues have on business as well as the related risks and opportunities. As a financial institution, Mizuho will take appropriate action in response while also taking into consideration factors such as international concerns and trends.

Risks and Opportunities for Mizuho


As a result of the growing seriousness of climate change, natural disasters are occurring, and, depending on their magnitude, may have a damaging impact on Mizuho's offices, computer centers, and other facilities both in Japan and overseas. If economic conditions deteriorate, many companies may experience weak performance, and this may have a detrimental effect on the Group's performance and financial position. In addition, there is a possibility that the cost of responding to tightening of regulations regarding environmental pollution and greenhouse gas emissions may rise, and, if corporations do not respond appropriately, this may have a negative effect on corporate reputations and thus lead to the risk of losses for the Group.


On the other hand, climate change may also lead to opportunities for the development of products and services that contribute to the reduction of greenhouse gas emissions and the greater use of renewable energy.

Mizuho has positioned global issues related to the environment and energy as matters to be addressed in its Group CSR Initiatives for the period from fiscal 2016 through fiscal 2018, which include "Developing Industries that Address Global Issues Related to the Environment and Energy," "Promoting Responsible Lending and Investing," and "Promoting Reduction in the Environmental Burden of Corporate Activities."
