Cool Biz campaign

The Cool Biz dress code advises workers to starch collars so they stand up and to wear trousers made from materials that breathe and absorb moisture.

[2] The MOE conducted a web-based questionnaire survey on the Cool Biz campaign on September 30, 2005, covering some 1,200 men and women randomly extracted from an Internet panel recruited by a research company.

Based on these figures, the Ministry estimated that the campaign resulted in a 460,000-ton reduction in CO2 emission, the equivalent volume of CO2 emitted by about 1 million households for one month.

[3] The Ministry also stated that it intends to continue encouraging people to set summer office temperatures at no lower than 28 °C as well as to work to have the Cool Biz concept take permanent root in society.

[4][5] On the other hand, the Ministry of Economy, Trade and Industry (METI) analyzed that the Cool Biz campaign increases replacement demand for clothing and generates positive macroeconomic effects on the GDP by 18 billion yen in summer 2005.

Thus, Warm Biz is more often referred in an environmental conservation context since fossil fuel heating releases more carbon dioxide than air conditioners do.

To conserve energy, the government recommended setting air conditioners at 28 degrees Celsius, switching off computers not in use, and called for shifting work hours to the morning and taking more summer vacation than usual.
