Palo Alto, CA— A new study by scientists at the Carnegie Institution finds 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. Some countries, such as Switzerland, "outsource" over half of their carbon dioxide emissions, primarily to developing countries. The study finds that, per person, about 2.5 tons of carbon dioxide are consumed in the U.S. 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.

"Instead of looking at carbon dioxide emissions only in terms of what is released inside our borders, we also looked at the amount of carbon dioxide released during the production of the things that we consume," says co-author Ken Caldeira, a researcher in the Carnegie Institution's Department of Global Ecology.
