Green Loans

Uses of "Green Loans" are limited to business activities that show due regard for the environment. As the flow of funds into ESG (environment, society, and governance) investments has expanded, in March 31, 2018, the Loan Market Association and the Asia–Pacific Loan Market Association jointly prepared and issued their Green Loan Principles (hereinafter the Principles), which are the rules for making loans and specify that the funds must be used in the environment–related fields.

On August 24, 2018, Mizuho Bank signed its first green loan contract based on these Principles. Going forward, Mizuho will also provide proactive support for companies that are responding to ESG issues through the provision of green loans.

Providing of new fund–raising methods and investment products aimed at wider use of renewable energy sources

To assist in the development of a sustainable society, we provide various types of support to expand the use of renewable energy. In June 2016, the Takara Leben Infrastructure Fund, which invests mainly in photovoltaic facilities, became the first fund to be listed on the Tokyo Stock Exchange's Infrastructure Fund Market. At the time, we provided our full support with Mizuho Securities acting as the listing lead manager, Mizuho Trust & Banking performing the role of an administrator of the investors' registry, and Mizuho Bank serving as the lead in arranging the financing. Entities across the Mizuho group have collaborated to support IPOs and new equity issues in the Infrastructure Fund Market, as well as support funding related to renewables and market investment products throughout the world. The total amount underwritten by Mizuho Securities from 2016 as of the end of March 2019 was JPY 32.6 billion, accounting for over 50% of the JPY 63.9 billion in issuances for the entire listed infrastructure fund market.

Mizuho Eco Finance

To promote the shift to a low–carbon society alongside our clients, in June 2019 Mizuho Bank and Mizuho Information & Research Institute launched Mizuho Eco Finance (Mizuho Environmentally Conscious Finance). This service evaluates the climate change initiatives of clients, allowing us to provide further support via financing and consulting to companies who are actively engaged in combating climate change.

Using an environmental assessment model developed by Mizuho Information & Research Institute featuring a globally accepted environmental verification and evaluation program, Mizuho Bank will provide financing to clients who meet a certain minimum score, and through monitoring by Mizuho Information & Research Institute, we will provide strategic advice to clients to improve and maintain their scores.

Environment–related loans to individual customers

To support individuals' environmental protection efforts, Mizuho Bank offers loans with lower interest rates that are available to customers who want to remodel their existing home, or build or purchase a new home that is more environment–friendly, such as employing solar power generation or all–electric systems. With this in mind, we are also implementing a system under which we will purchase 1.4 tons of domestic CO2 emissions credits for each eligible loan transaction and donate them to the national government.

Under this initiative, Mizuho Bank loans benefit the environment not only through the environment–friendly homes purchased using the loans. This initiative also contributes to the proactive environmental efforts of Japanese companies by promoting the J–Credit Scheme (formerly the Domestic Credit Scheme) as well as the attainment of Japan's CO2 emissions reduction targets.

  • *The Domestic Credit Scheme and the Offset Credit (J–VER; Japan's verified emissions reduction) Scheme was integrated in 2013.

Natural Disaster Support Loans

In cooperation with Sompo Japan Nipponkoa Insurance Inc., Mizuho Bank has begun offering housing loans with built–in relief for disaster–affected customers in the event of an earthquake, disaster resulting from a torrential rainstorm, or other natural disaster, through which eligible customers have part of their scheduled payments or loan debt reduced. This housing loan product addresses risks that are not fully covered by conventional insurance, and by partially reducing scheduled payments or loan debt in the event of a natural disaster, can reduce the strain on household finances, specifically the burden of housing loan repayment.
