Measures to Fight Climate Change

Japan

The Paris Agreement, issued in 2016, pledges to keep the rise in global temperature to well below 2 degrees Celsius above pre-industrial levels and to pursue efforts to limit the temperature increase to 1.5 degrees Celsius.
The Kyocera Group also recognizes measures to fight climate change to be a priority issue. We set 2°C level of long-term environmental targets in 2018. We renewed our long-term environmental target to 1.5°C level target and are implementing various measures to prevent global warming, including energy saving measures.

Long-term Environmental Targets

In 2016, the Paris Agreement came into effect, and nations and companies are working to reduce greenhouse gas emissions. The Kyocera Group also considers climate change measures to be an important issue. In 2018, we set a long-term environmental target (2°C level: 30% reduction in GHG emissions in FY2031 compared to FY2014) and received SBT certification in 2019. Subsequently, we consider updating the target based on social demands. We updated the target in 2020 to 1.5°C level (46% reduction in FY2031 compared to FY2020, equivalent to 56% reduction in FY2031 compared to FY2014).

Kyocera Group Long-term Environmental Targets

Scope* 1, 2 GHG emissions: Reduce 46% by FY2031 compared to FY2020 levels
Scope* 1, 2, 3 GHG emissions: Reduce 46% by FY2031 compared to FY2020 levels
Renewable energy adoption: Increase 20x by FY2031 from FY2014 levels
Carbon neutral by FY2051

Scope 1: Direct emission associated with fuel consumption and production processes

Scope 2: Indirect emission associated with consumption of power or heat purchased from outside

Scope 3: Indirect emission other than Scope 1 or 2 (Including procurement of raw materials, transport, use and disposal of products, as well as employee commuting and business trips)

Measures to Fight Climate Change

In order to achieve our long-term environmental goals, we are actively implementing energy conservation measures and introducing renewable energy at all of our locations. Concrete energy conservation measures include the promotion of company-wide fuel conversion from liquefied petroleum gas to cleaner natural gas, replacement of HFC refrigerant equipment, and introduction of LED lighting. We are also introducing renewable energy sources at our domestic and overseas sites, with the total cumulative power generation capacity reaching approximately 22 MW as of 2021. As a result of these activities, we have reduced greenhouse gas emissions by 9.8% compared to FY2020.

Installation of Solid Oxide Fuel Cells (SOFC)

The SOFC is a very energy-efficient power generating unit that produces electricity through a chemical reaction between a fuel (hydrogen) and oxygen. It can also provide heat as an energy source by retrieving waste heat from this chemical reaction. Kyocera has installed SOFCs at our Shiga Gamo, Shiga Yohkaichi, Shiga Yasu, and Kagoshima Kokubu plants. The retrieved waste heat is used to heat the cafeteria hot water supply, to provide supplemental hot water for the boilers, and to heat water for absorption chillers that produce air conditioning.

Renewable Energy "Self-wheeling" Demonstration Test Utilizing Storage Batteries

When a site cannot be secured for a solar power generating system, renewable energy can be used by the "self-wheeling" of electric power from solar power generating systems located elsewhere. In July 2020, Kyocera Corporation launched demonstration tests of Japan's first renewable energy self-wheeling system using a storage battery in Yasu, Shiga Prefecture. A Kyocera-manufactured 150 kW solar power generating system was constructed on a roughly 2,000 m2 site owned by the city of Yasu. The renewable energy generated by the system is supplied to our Shiga Yasu Plant, approximately two kilometers away, via Kansai Transmission and Distribution, Inc's electrical power grid. Via this demonstration test, we aim to establish a business model for "Self-wheeling," for which we expect to see a growing demand in the near future.

Fuel conversion

Kyocera's Kitami Plant in Hokkaido, Nyuzen Plant in Toyama Prefecture, and Sendai Plant in Kagoshima Prefecture are working to reduce CO₂ emissions by converting their production fuel from petroleum-based fuels to LNG (natural gas), which has a low CO₂ emission coefficient.

CO₂reduction (estimated)：5,306（t-CO₂/年）

Breakdown: {Kagoshima Sendai Plant: 3,100 t-CO2/year), Toyama Nyuzen Plant: 1,977 t-CO2/year), Hokkaido Kitami Plant: 229 t-CO2/year)}

Energy-saving Policy: Installation of high-efficiency equipment

At Kyocera's Shiga Yasu Plant, compressed air and chilled water for air conditioning are supplied to each building by a central system. These have been replaced with high-efficiency air compressors and chillers that adjust the amount of output to save energy.

ReducedCO₂Emissions (estimated)：1,975（t-CO₂/year）

Replacement with alternative CFC refrigerator equipment

Production and import of specified CFCs (HCFC) are regulated to protect the ozone layer, and the production of specified CFCs (HCFC) stopped in developed countries in 2020. As a result, we are replacing our air conditioning systems with alternative CFC refrigerants (HFC). For packaged air conditioners and chillers, 15-year-old equipment will be replaced by FY2025, and other equipment, including dryers and small chillers, will be replaced by FY2028.

CO₂ emissions reduction (estimated)：12,300（t-CO₂/year）

Promote visualization of CO₂ emissions

By visualizing CO₂ emissions and centrally managing data, we compare our actual CO₂ emissions with our targets to better track our sustainability performance and raise employee awareness. We are also promoting visualization of CO₂ emissions at each production facility to identify hot spots and prioritize countermeasures for efficient CO₂ emission reduction.

Update to LED

Since 2012, we have been replacing fluorescent lamps with LEDs, mainly in areas where energy-saving effects are significant. The plan is to replace all fluorescent lights, except for those in special areas such as explosion-proof areas, by FY2024, and to replace exterior lights, downlights, etc. with LEDs by FY2029.

CO₂reduction (estimated)：2,200（t-CO₂/year）

Introduction of Solar Power Generation Systems

We are installing solar power generation systems at our premises in Japan and overseas.

Green curtain initiatives

As part of its energy conservation activities during the summer, the Kyocera Group has been promoting the use of "Green Curtains" since FY2008. Plants such as bitter gourds and morning glories are grown in the windows and outer walls of buildings to block sunlight and reduce our reliance on air conditioning.
