We’ve reported earlier about Japan’s zany “warm biz” program that encourages businesses to lower the thermostat in winter and get people to wear warmer clothes.

Well, it turns out the program has saved as much as 460,000 tons of CO2 last summer alone. Article here. No word on the fate of overheated officeworkers.
