Environmental Policy
Basic Approach

The NGK Group recognizes that protecting the environment, on Earth and in space, is a vital issue that all of humanity must face. Therefore, to bring our business activities into harmony with the environment, guided by the NGK Group Environmental Vision, we will bring our core principles of carbon neutrality, a circular society, and harmony with nature to life by committing to achieve Net Zero, advance a Circular Economy, and foster a Nature-Positive world. We also work to solve environmental issues with an awareness of the impact our business activities have on the environment and society, as well as the impacts the environment and society have on our business activities. Through initiatives like these, we strive to reduce the environmental impact of business activities and help protect the environment by developing products and technologies conducive to environmental conservation.

Main Focus


1. Strive to develop, design, and manufacture products that contribute to the environment and products with low environmental impact.
2. Work to reduce the environmental impact arising from business activities. Use tools such as design review to conduct a scientific investigation and evaluation of the impacts our business activities have on the environment.

  • Promote energy conservation measures and expand the use of renewable energy for all processes and facilities, and make efforts to reduce CO2 emissions by reducing energy use and using energy efficiently.
  • Promote resource efficiency (including reduction of natural resources use) and expanded use of recycled materials, and reduce the generation of waste materials (including valuable materials ).
  • Manage the risks of water resources, promote water saving and reuse, and strive to reduce the amount of water withdrawal in our business activities.
  • Through the appropriate use and control of chemical agents, work to reduce the risks inherent in toxic substances.
  • Give precedence to environmentally friendly materials, parts, products, and facilities in procurement and purchasing, strengthening cooperative alliances with our business partners.
  • Help to protect biodiversity by reducing our impact on the environment and developing/distributing eco-friendly products.

3. Enhance environmental management systems from a global perspective while continuously reducing our environmental impact. Carry out risk management based on scenario analysis in order to continue our operations while responding to environmental changes.

4. Work to prevent environmental pollution of the atmosphere, water, and land, and promote environmental conservation by abiding by environmental laws, regulations, and other requirements, and instituting our own voluntary standards. Also, strive to protect the environment so that our business activities will not prevent any local people from enjoying clean water resources.

5. Provide environmental information to the public at the appropriate time and pursue dialogue with all stakeholders. Proactively develop social action programs. Also, engage in education and publicity in order to improve employees’ environmental consciousness.
