NTT has already set up an Environmental Problem Measures Office, as well as a Global Environment Protection Advisory Committee to address issues related to the global environment. One result is the adoption of the "NTT Global Environment Charter" in October 1991 by the NTT Group of companies. The charter clarifies the company's basic position on issues of global environment. At the same time, a "Basic Program of Global Environment Protection" is set forth, including guidelines for NTT activities and countermeasures and describing specific activities. This program remains in effect to this day.
