Case Studies (Reducing Environmental Burden)

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.

In fiscal 2016, the green power produced by this project was also used for the Ordinary General Meeting of Shareholders and the Coming of Age Day Concert, the printing of environmental education materials that were distributed to employees, and the printing of the in–house newsletter. Total power used for these purposes amounted to 15,114 kilowatt–hours in fiscal 2016. This corresponds to a deemed reduction of approximately 7.6 tons of CO2 emissions.

  1. *1The project is being promoted through the cooperation of Yokohama residents, business establishments and the government. Residents participate in the project 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.

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 are 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.
