Head Office Plant Completes Switch to Carbon-free Power

Hioki is pleased to announce that its Head Office Plant completed its transition to carbon-free hydro-power for all operations on April 1, 2021. As a result, the Head Office Plant now uses 100% renewable energy *and generates no CO2 emissions from power use.

The company began using carbon-free power from Chubu Electric Power Miraiz Co., Inc., for one-third of the Head Office Plant's energy needs in January 2020 as part of an effort to slash greenhouse gases before increasing that figure to 100% in April 2021. The change brings Hioki’s use of carbon-free power in Japan to 98.6% and allows the Head Office Plant to save the equivalent of about 5,500 megawatt-hours of CO2–some 2,300 tons–each year*.

This initiative, one of a number of priority measures identified in Hioki’s effort to implement Vision 2030, which lays out the direction of the Hioki Group over the next 10 years, will help resolve environmental issues in order to realize a carbon-neutral society.

Going forward, Hioki will continue to work to achieve a sustainable society by pursuing more environmentally friendly business activities, for example by promoting use of safe, environmentally-friendly electricity, strengthening energy-saving programs, and reducing environmental impacts throughout its value chain.
