Efforts to Reduce CO₂ Emissions

We would like to inform that Yamaichi Electronics group aims to reduce CO₂ emission by 40% in 2030, compared to the basic unit per consolidated sales revenue of the fiscal year 2021. We will also try to meet carbon neutrality in 2050.

*Our CO₂ emissions intensity is the CO₂ emissions per consolidated sales revenue.
Actual result of CO₂ emissions per unit in 2021: 0.36t/million yen

Environmental Response

Reducing approximately 350 tons of CO₂ emissions per year through the use of renewable energy

In 2020, we introduced solar panels and sodium-sulfur (NaS) batteries to the production lines at the Sakura Factory (Chiba Prefecture) to prevent power outages caused by typhoons and other natural disasters from interrupting the power supply. By using solar power generation during the day, using discharged power from the NaS batteries at night, and effectively utilizing the power charged in the NaS batteries during low load periods on holidays, we have reduced the amount of electricity used. With this system, the share of renewable energy in the power consumption of the Sakura Factory is now around 20%. The factory reduces CO₂ emissions by about 350 tons per year.
The factory also signed an Agreement on the Temporary Use of Facilities in the Event of a Disaster with the city of Sakura, Chiba Prefecture, and has been certified as a regional disaster evacuation center that provides electricity and use of parking lots.
