Cool Biz means setting your air conditioner to 28C (82F). Some Japanese have actually been duped into this terrible idea.

Japan's Ministry of the Environment (MoE) hopes this will somehow reduce global warming. But it can't, since the electricity to run Japanese air conditioners comes from hydroelectric and nuclear generators, not fossil fuels. Instead it'll just lower the already infamously low productivity and creativity of Japanese office workers, lengthening their afternoon naps, and discouraging all motion and thought. Even though Japan makes some of the best air conditioners in the world, the MoE wants Japan to return to preindustrial third-world status.

The "Cool Biz" ad campaign reached 96% of Japanese, and 33% actually turn up their thermostats. In 2005 this reduced carbon dioxide emmisions from Japanese homes by 1/1000. (But of course most emmisions come from factories and cars. Why would houses be emmitting carbon dioxide at all?)

The MoE hoped "cool biz" would encourage less formal clothing. But in formal Japan, most workers still have to wear ties and jackets. Cool biz is a terrible failure.

Japanese people have to tape ice packs to their clothing:
