Announcing the launch of Mizuho Eco Finance

June 28, 2019

Mizuho Bank, Ltd. (President & CEO: Koji Fujiwara) and Mizuho Information & Research Institute, Inc. (President & CEO: Yasumasa Mukai; “MHIR”) today launched a service entitled Mizuho Environmentally Conscious Finance (“Mizuho Eco Finance”) through which we will take action alongside our clients to advance the shift to a low–carbon society. Today Mizuho signed an agreement with Sapporo Holdings Limited (President and Representative Director: Masaki Oga) as our first client for this new service.

Through this service, Mizuho Bank will provide financing to clients who meet a certain minimum score based on our scoring system, which utilizes an environmental assessment model developed by MHIR to evaluate client initiatives and benchmarks via a globally accepted environmental verification and evaluation program. Through monitoring, MHIR will provide strategic advice to clients to improve and maintain their scores.

Climate change is closely tied to various economic and social issues, and we recognize that addressing climate change is an important issue over the medium to long term. As a financial services group, we are dedicated to engaging in dialogue with clients and other stakeholders as a trusted consultant, and we are proactively addressing climate change to support the shift to a low–carbon society. Developed as one part of this commitment, the Mizuho Eco Finance service will evaluate the climate change initiatives of our clients and provide further support for the initiatives of companies that are active in such areas by providing capital financing and strategic advice.

At Mizuho, we are working to further incorporate sustainability initiatives into our strategy and strengthen our group–wide framework for promoting sustainability. We will draw on our expertise as a financial services group to proactively provide a wide range of solutions, including providing capital financing support to businesses that are contributing to the shift to a low–carbon society.
