Advantest’s Gunma Factory Achieves 100% Renewable Energy Use
published in Testing on 08/04/2021
TOKYO, Japan - April 8, 2021 - Leading semiconductor test equipment supplier Advantest Corporation (TSE: 6857) today announced that from April 2021, all power used at its primary production plant, the Gunma Factory in Gunma Prefecture, Japan, will be sourced from renewables.
The renewable energy used at the plant is a net-zero source of carbon emissions. It is locally produced for local consumption at a hydroelectric power plant owned by the Gunma prefectural government. The environmental added value obtained from electricity fees collected (surplus to operating costs) is used by the prefecture for future-oriented projects.
The Gunma Factory consumes about 12.8 million kWh of electricity per year, and it is expected that by switching entirely to renewables, the factory's CO2 emissions will be reduced by about 5,000 tons of CO2 per year, equivalent to the amount of CO2 that about 360,000 cedar trees absorb annually. (A single Japanese cedar absorbs approximately 14kg of CO2 per year, according to the Japanese Forestry Agency.)
Advantest has previously achieved 100% renewable energy usage at its subsidiaries in the United States and Europe. With this new announcement, the company estimates that the renewable energy adoption rate for the entire Advantest Group will increase from 28% in 2019 to 44% in 2021.
As a part of Advantest's contribution to the goal of "decarbonizing society", the company aims to raise its renewable energy adoption rate to 60% or greater by 2030. It is promoting the introduction of solar generators and other renewable energy sources at its Japanese facilities, and also planning the switch to renewables at its subsidiaries in Asia, based on the availability of renewable energy sources in each region. In addition, Advantest is working together with its suppliers and partners to reduce CO2 emissions across its supply chain.
