Utilization of Renewable Energy

Casio is promoting the use of renewable energy and expanding its efforts at each of its offices in Japan and overseas. As part of these efforts, in 2021 we switched to a renewable energy electricity menu for the electricity used at six offices in Japan, including Casio Computer headquarters, and in 2023 we began using electricity derived from renewable energy at our Zhongshan plant in China under a PPA model.

Furthermore, Yamagata Casio, a production site in Japan, switched to a renewable energy electricity menu in April 2024, and Casio Thailand, a production site in Thailand, has concluded a private power purchase agreement for solar power generation with the aim of starting use in 2025.

Using insulation to reduce energy use

The company reduced the air-conditioning cooling load by installing insulation around the exhaust ports of the reflow system and dryer to block heat conduction and this has helped to reduce greenhouse gas emissions.

Introducing the latest energy-saving air-conditioning systems

A new watch plant that started operations in May 2018 uses the latest energy-saving air-conditioning systems, such as an air-conditioning system with several air-conditioners with FFUs^*1 and ceiling cassettes, zoning and separate air-conditioning for clean rooms. These systems enable efficient operation according to the production situation.

*1 FFU: Fan-filter unit. A system that passes air sucked in by the fan through a filter to purify it before sending it out as clean air.

Installation of LED Lighting

Casio is installing LED lighting at its business sites to reduce electricity consumption. Thus far, it has installed LED lighting at many Casio sites, including the Hatsudai Head Office, Hamura R&D Center, Yamagata Casio, Casio Electronics (Shenzhen) Co., Ltd., Casio (Thailand) Co., Ltd., Casio America, Inc., and Casio Electronics (Shaoguan) Co., Ltd., and other sites. The installed LED lighting has brought about substantial CO2 emissions reductions.
