 Energy Conservation and Prevention of Climate Change
Introduction of Recyclable Energy (Solar Power Generating System)
The Kyocera Group installed solar power generating systems, which use light, one type recyclable energy, at major sites inside and outside Japan, including the global headquarters in Kyoto, Kyocera International Inc. in North America, in addition to other ongoing energy-saving activities.

In FY2018, the solar power generating system was expanded at the Kyoto Ayabe Plant. All those solar power generating systems including those inside and outside Japan, currently have the output capacity of about 12 MW of power (about 12,000 MWh/year in power output). We continue to introduce solar power generating systems at major sites of the Kyocera Group to promote the reduction of CO2 emissions.

Cultivating "Green Curtains"
The Kyocera Group started the "Green Curtain" campaign in 2007, which aims to cultivate climbing plants such as goya or morning glory around, over, or on parts of windows and external walls of buildings to block strong summer sunlight and thus reduce air-conditioning loads as part of our summer energy-saving activities.

Since Green Curtains are an ecological activity that we can conduct by hand, we distribute seedlings to local residents and employees to help spread the activity. Harvested goya are provided in our company cafeteria or distributed at summer festivals held by Kyocera.

Energy Consumption Reduction by Introduction of Inverter-controlled Air Compressor

The Toyama Nyuzen Plant previously used compressed air in its manufacturing process, which consumed a large amount of electricity. After the Plant introduced inverter-controlled air compressors, which allows operation depending on the load, use of the new compressors successfully led to reduction in power consumption and CO2 emission.

 Effective use of Water Resources
Water Consumption Reduction by Revision of Production Processes and Effective Use of Wastewater Recycling Equipment
The Niigata Shibata Plant conducted a review of wastewater reuse (for cascade use) in plating equipment and the effect on water supply quantity. Effective use of the wastewater recycling equipment and an increase in the recycling water quantity successfully resulted in reduction in water consumption.
