Hawaiian Shirt Environmentalism

This year Japan instituted "Super Cool Biz," a government campaign to encourage sandals, shorts and Hawaiian shirts at work to avoid nation-wide blackouts:

In 2005, the Japanese government launched a predecessor, Cool Biz, with a subtler sartorial assault (nix the jacket and tie) and a headier goal (fight global warming by using less air-conditioning). Most people dismissed the idea back then, but polls now show about 66% worker support. It has cut roughly 5 million metric tons of greenhouse gases–which goes to show that cultural changes can lower energy use as much as technological ones.
