UN staff to wear less

The United Nations is encouraging its New York staff to trade wool business suits for cooler attire this summer so the organization can slash air conditioning costs and help the environment.

"There is going to be a relaxing of the dress protocols and people are being encouraged to wear lighter clothing," said US architect Michael Adlerstein, who is overseeing a $1.8 billion renovation of the 60-year-old UN skyscraper.
