Initiatives to Prevent Environmental Pollution

Environmental Compliance

The Kyocera Group has established autonomous environmental management standards for each site that are stricter than statutory and public regulations on emissions, wastewater, soil, groundwater and other areas of concern. We take periodic environmental measurements to ensure thorough compliance.
In FY 2020, the Kyocera Group received two complaints regarding environmental laws, regulations, and administrative guidance, and five complaints about noise and vibration, all of which have been promptly corrected and addressed.

Principal Kyocera Group sites in Japan, and some of our overseas sites, have acquired integrated ISO14001 certification

Evaluation of compliance at production sites in China

In order to prevent environmental pollution and ensure compliance, the Kyocera Group is working to establish a system to monitor the status of compliance with environmental laws and regulations and their changes, and take appropriate measures. From FY 2019 to FY 2020, we conducted third-party evaluations focusing on checking compliance with environmental laws and regulations at our production sites in China, where environmental regulations are being reviewed and strengthened. In FY2019, we evaluated 2 production sites, and in FY2020, we evaluated 8 production sites (A total of 10 production sites were evaluated). In FY2021, we made efforts to rectify the issues pointed out in this evaluation, with 92% successfully completed. We will continue to correct the remaining items to prevent environmental pollution and ensure compliance.

Targets for FY2021 Completed correction of environmental compliance assessment (third-party assessment) at 10 production sites in China
in Fiscal Year 2020
Remediation Status: 92% Complete
Targets for FY2021 The Kyocera Group conducts environmental impact assessments at each site to reduce the impact on the natural environment and ecosystems, actively promotes green activities at business sites, and participates in and supports local social contribution activities.

Control of Chemical Substances

Some chemical substances can cause environmental pollution and/or affect human health and the ecosystem. The Kyocera Group sets a voluntary control standard and takes initiative in carrying out environmental impact mitigation activities.

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. We also control the handling volumes and emissions of volatile organic compounds (VOC), which are a source of suspended particulate matter and photochemical oxidants.

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.

Reports on Soil and Groundwater Contamination

The Kyocera Group (Japan) conducts soil surveys and provides survey reports to competent local governments according to the Soil Contamination Countermeasures Act.
Consequently, a total of five locations were designated as areas which require action under the Act: Asahi City, Chiba, in 2013; Ebetsu City, Hokkaido, in 2014; Hachioji City, Tokyo, in 2014; Mikasa City, Hokkaido, in 2015; and Kawasaki City, Kanagawa, between 2018 and 2020. No confirmation of any spread to or impact in the surrounding areas of those sites has been reported.
We are taking appropriate measures in close cooperation with each associated municipality.

Overall Environmental Impact

The Kyocera Group (Japan) tracks and manages business activities and environmental impact.
Data from the procurement, manufacturing, distribution, use, disposal, and recycling stages are used at each stage to formulate policies and analyze and evaluate the results to effectively reduce environmental impact.

Material Balance
  • In accordance with the Act on the Rational Use of Energy, we calculate the distribution-related impact based on report data such as the use of energy in transportation by the specified consigner (Kyocera).
  • We calculate the annual power consumption of the main products we sold in FY2020 (printers, multifunctional products, smartphones, etc.).
  • We calculate the annual greenhouse gas emissions of the main products we sold in FY2020 (printers, multifunctional products, smartphones, etc.).
  • We calculate the weight of toner containers reused in FY2020. (Kyocera Document Solutions Inc.)
  • The VOC aggregate range shows data for Kyocera Corporation sites in Japan.
