The Tokyo Metropolitan Government will apply for ISO 14001 authorization, an international standard for environmentally friendly office management, by the end of fiscal 1999, Tokyo Gov. Yukio Aoshima said Friday.A total of 1,174 organizations have obtained the authorization across the country, including three local governments as of August, according to metropolitan government officials.The metro government building in Shinjuku Ward represents the largest single office to apply yet for the authorization in Japan, with 13,000 public servants working there. To obtain the authorization, the metropolitan government will designate environmental managers at each bureau, and set a number of targets to make the office more environmentally friendly.The targets will include increasing the percentage of paper used that is recycled to more than 70 percent and cutting electricity use by more than 10 percent.At a news conference Friday, Aoshima said his "no-tie" campaign to promote casual clothes at work in summer to curb energy for air conditioning, saved about 70 million yen last summer.
