make-up

The U.S. has 5% of the world's population, says the Wall Street Journal, and burns 23% of the world's oil. But what's striking is the make-up of the carbon footprint.

'Industry -- including oil, steel, chemicals and cement -- produces 23% of U.S. greenhouse-gas emissions, according to the McKinsey study. But a handful of other emission sources more directly controlled by consumers far outweigh industry when those sources are pooled together ... Consumer behavior affects virtually all man-made greenhouse-gas emissions because consumers drive the economy.'
