Global Warming Underwear in Japan:
NPR: Two years ago, the Japanese government instituted a new policy that has so far trimmed more than two million tons of greenhouse gases from the country's growing emissions: Get men to stop wearing suits and ties in the summer. That way, office buildings could ease up on the air conditioning, and set temperatures at 82 degrees Fahrenheit — that's seven degrees warmer than what you might find in a typical U.S. office building.
The campaign is called "Cool Biz," and generated some initial complaints from some tie-makers, but stimulated a new industry for "global warming clothing" including the "Su su suit," a one-pound suit for $500, so light you barely know you're wearing it, and "global warming underwear" (pictured above).
