TNSC Obtains Blanket ISO14001 Certification

Taiyo Nippon Sanso Corporation recently obtained blanket certification under the ISO14001 international
standards for the operation of its environmental management system across the whole Company.
Our Electronics Division and our Chubu Regional Branch had already obtained ISO14001 certification,
but with this recent blanket certification, we have now obtained recognition of compliance with international
standards at all the Company’s offices and supply centers, including the Company’s headquarters, all sevenregional branches, all 24 branches, all 14 sales offices, all 20 gas centers, and our other offices in Keihin, Tsukuba,Yamanashi, and Kawasaki Mizue.
Environmental protection activities are included in the basic management policies of TNSC, and wehave actively addressed this issue, as a result of which we obtain ISO14001 certification for the environmentalmanagement systems at our Oyama Plant in 1999, for our Electronics Division in 2001, and for our Chubu
Regional Branch in 2003.
For all our other business premises, we have applied both Companywide environmental targets andenvironmental management system regulations specific to individual places of business, and our staff haveautonomously pursued such activities. However, the operation of environmental management systems individually
by offices or production facilities has produced only limited results.
In view of this situation, we have judged that a Companywide approach to environmental management
system operation is essential if we are to effectively reduce the environmental load caused by our businessactivities. We therefore introduced a unified environmental management system that is applied to the whole
Company. This system was inspected by the certifying institute and found to be in compliance with therequirements for receiving the blanket ISO14001 certification.
We will maintain constant efforts to further improve our environmental protection activities as part ofour corporate social responsibilities.
