Initiatives in Japan

Utilizing Green Power

Green power refers to electric power generated by renewable energies that have a low environmental impact like wind, solar and biomass.

Mizuho has taken part in the Yokohama Wind Energy Project*1 since April 2007 and currently uses green power generated by the project for diverse events.

At MHFG's 13th Ordinary General Meeting of Shareholders held in June 2015, the green power produced by the Yokohama Wind Energy Project provided all the power (1,685 kilowatt–hours) used for the meeting. This corresponds to a deemed reduction of approximately 1 tons of CO2 emissions.*2

The green power produced by this project was also used for the printing of environmental education materials that were distributed to employees, the in–house newsletter, and the Coming of Age Day Concert. Total power used for these purposes amounted to 13,713 kilowatt–hours in fiscal 2014.

  1. *1The project is being promoted through the cooperation of Yokohama residents, business establishments and the government. Residents participate by purchasing publicly offered bonds for wind power projects dubbed "Hama Kazaguruma Bonds." Companies participate by cosponsoring the project as "Y (Yokohama)–Green Partners" and receiving "the Certificate of Green Power" in return. MHFG is involved in the project as a Y–Green Partner, while MHBK and Shinko Securities (now MHSC) participated by handling the bond issue.

Use of "Green Curtains"

As part of its electric power conservation efforts, the MHIR has created heat–insulating "green curtains" of vegetation on the exterior of its head office building as well as of its information center building.


Environmentally Friendly Gifts

Promotional gifts given to customers at branch counters are created while considering not only user–friendliness but also environmental friendliness.

The paper used to produce calendars distributed by MHFG and paper bags distributed by MHBK, MHTB, and MHSC is made from wood harvested in forestland certified by the Forest Stewardship Council (FSC). MHSC uses environmentally friendly materials in its calendars. In addition, the Mizuho IC Cash Card is made from an environmentally friendly material, PET–G, a non–halogen plastic that has a low environmental impact at disposal.

Overseas Initiatives

At all of its locations throughout the world, Mizuho is cutting CO2 emissions – mainly by saving electricity – thoroughly separating waste, reducing paper usage, and taking various other steps to reduce its environmental burden.
