Carbon emissions 'outsourced' to developing countries

Scientists at the Carnegie Institution report that over a third of carbon dioxide emissions associated with consumption of goods and services in many developed countries are actually emitted outside their borders. The study finds that, per person, about 2.5 tons of carbon dioxide are consumed in the US but produced somewhere else. For Europeans, the figure can exceed four tons per person. Most of these emissions are outsourced to developing countries, especially China.
