NKK AND THE ENVIRONMENT

As a responsible corporate citizen, NKK implements voluntary controls and undertakes activities that serve to ameliorate the impact of its operations on the environment. The Corporation has continuously endeavored to maintain a balance with the natural environment by utilizing its technical edge. Not only have we tackled ecological issues in the field of steel production, but we have also contributed to the development of effective methods for the recycling of industrial waste, preservation of water quality and conservation and effective use of energy. The Corporation seeks to work with local communities in the establishment of a recycling-oriented society and consistently augments its efforts to conserve energy and protect the environment.

NKK Named World's Most Eco-Friendly Steelmaker

In September 2000, NKK captured top spot in the steelmaking category with an AAA rating in environmental management from the U.S.-based Innovest Strategic Value Advisors. This recognition substantiates our high reputation and commitment to the environment.

      The rating highlighted three aspects of NKK's eco-friendly initiatives:

  • Self-imposed discipline as a responsible corporate citizen keenly aware of the pressing concerns posed by global warming; and the application of leading-edge technologies and systems to protect the environment and conserve resources
  • Steady focus on environmental issues since the early 1970s and numerous results through such initiatives as life-cycle assessment, energy-saving programs, by-product reduction, protection of existing environments and creation of new green zones
  • Support for the environment through the promotion of eco-businesses, as well as production of eco-friendly steel products and development of steel and engineering-related technologies and materials, including ECOARC, DME, waste plastics recycling and regenerative burners
