As part of a national effort to conserve energy and reduce air conditioning usage, the Japanese government announced that its workers do not need to wear ties and jackets to work during the summer months. The effort called, "Cool Biz", endorsed by the highest government officials, began on Wednesday. The purpose of the campaign is to meet Kyoto global warming protocols. This protocol is an international agreement that sets targets to reduce the greenhouse gas emissions causing climate change.
Prime Minister Junichiro Koizumi has appeared in a television advertisement, dressed in a half-sleeve shirt with no tie, and encourages his cabinet members to follow suit. According to the Associated Press, this change in office dress code in Japan, a country where conformity and tradition are highly prized, may prove challenging for workers to adopt. Two previous similar attempts by both Prime Minister Masayoshi Ohira in 1979 during the "oil shock" and Prime Minister Tsutomu Hata in 1994 were unsuccessful.
The Energy Conservation Center in Japan estimates that if all offices in the country participate in this campaign and raise their thermostats by five degrees, Japan could save 81 million gallons of oil in one summer.
