Efforts to Reduce Environmental Impact

Measures to reduce energy consumption

Medium-term environmental target

A 1% basic-unit reduction on average every year (5% or more improvements at the end of FY2024 based on FY2019 standards)
We aim to achieve an improvement of 5% or more by the end of FY2024, based on FY2019. Our goal is to reduce energy consumption by an average of 1% per year based on activities specified in ISO 14001. We are also managing CO2 emissions from energy sources as Scope 1.

Measures for Greenhouse Gas Reduction

Medium-term environmental target

A 1% basic-unit reduction on average every year (5% or more improvements at the end of FY2024 based on FY2019 standards)
Most greenhouse gas emissions from the Company are CO2 emissions associated with electricity. Among these, indirect CO2 emissions from electricity use are the main ones (Scope 2). We are also managing CO2 emissions at our overseas sites.

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.
