    • They aim to contribute to the capability of people of all generations to realize healthy, fulfilling lives by creating value that is useful in the development and revitalization of local communities.

Japan Post Bank is demonstrating continuous progress towards sustainable development through the publishing of regular sustainability reports. However, while the bank reports its progress in areas of sustainability, its goals are not measurable nor clear.

Their reduction of greenhouse gas emissions by 16% as part of their FY2030 reduction target demonstrates that the Group clearly works towards mitigating climate change. The bank also received several noteworthy awards for its advances.

Their LEED Gold certificates as well as their commitment to global initiatives such as UN Global Compact and Task Force on Climate-related Financial Disclosures (TCFD) are noteworthy.

Their compliance with several of the UN Sustainable Development Goals also shows that the Group is paving the way to sustainable financing. However, the bank’s compliance with these goals is too little, relative to other banks.

For these reasons, Japan Post Bank has been rated a C.

Analyst Outlook Neutral

Whilst Japan Post Bank is clearly working towards sustainability, the Group would benefit from earning more certificates and awards that validate their progress, as well as complying with more UN Sustainable Development Goals in order to achieve a higher ranking. For these reasons, our outlook is Neutral.
