 Energy Conservation and Prevention of Climate Change
Increased energy consumption has an impact on the environment, including negative effects such as climate change. We share the task of using the earth's finite energy resources more effectively, including for energy use in industrial activities.

The Kyocera Group works on measures for the prevention of climate change in various ways, including the setting of targets for greenhouse gases and energy reduction, and the implementation of energy-saving measures in business activities.

· Emission coefficients are calculated based on the Act on Promotion of Global Warming Countermeasures.
· Greenhouse gas means CO2, CH4, N2O, PFC, HFC, and SF6.
· Figures for overseas facilities are calculated using the emission coefficients of electricity for each country in IEA CO2 EMISSIONS FROM FUEL COMBUSTION Highlights (2015 Edition).

Introduction of renewable energy (Photovoltaic power generation system)
The Kyocera Group has installed photovoltaic power generation systems, a renewable energy.
In FY2019, we installed at the Keihanna Research Center, and installed additional system to the Kitami Plant in Hokkaido, Koriyama Plant in Fukushima, and Hayato Plant in Kagoshima, bringing total power generation capacity to about 13 MW.

Third Party Verification of Greenhouse Gas (GHG) Emissions, Water discharged, Waste discharged, Hazardous waste discharged, VOC emissions and Social indicators
Greenhouse gas emissions (Scope1,2 ,and 3*), water consumption and discharged water, wastes and hazardous wastes, VOC, and social indicators were verified by a third party contractor, SGS Japan Inc., to improve data reliability. Their verification confirmed that Kyocera correctly totaled, calculated and disclosed data.

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)

 Effective Use of Water Resources
Water is a precious natural resource. However, the importance of water resources, or water risk, is increasing in some parts of the world because of the ongoing impacts of climate change.
The Kyocera Group carefully manages the intake and release of water and quantitatively assesses water risk at each production site using data from the Aqueduct Water Risk Atlas* such as water stress level, amount of water use, unit price of water, and local-level water stress assessment results. The water risk assessment found no production sites with high risk, but we set a target for water consumption for the entire Kyocera Group and continue to implement measures to protect water resources.

Waste acid treatment equipment

Waste acid treatment equipment
The Niigata Shibata Plant reduced industrial waste emissions by newly introducing treatment equipment and promoting in-house treatment of waste acid generated from the plating equipment.

【Annual waste emissions reduction】

 Chemical Substances Management
Some chemical substances cause environmental pollution and can affect human health and the ecosystem as a result of long-term accumulation. The Kyocera Group sets a voluntary control standard and takes initiative in carrying out environmental load reduction activities. In addition, the Kyocera Group (Japan) carries out thorough control of emissions and the transferred amount of Class I Designated Chemical Substances as prescribed by PRTR Law.
Management and Disposal of PCB Waste
The Kyocera Group (Japan) strictly controls and manages PCB (polychlorinated biphenyl) waste at specified locations with control sheets prepared in accordance with relevant laws. Kyocera has already become an early registrant for disposal of these wastes with the Japan Environmental Safety Corporation and will dispose of them accordingly.
