International Annual CO2 Emissions
Most of the world's greenhouse gas (GHG) emissions come from a relatively small number of countries. The United States, China, and the European Union (EU-25) together accounted for about 50% of global emissions in 2004. The eight largest emitters - the United States, China, the European Union, Russia, India, Japan, Germany and Brazil - accounted for more than 70% of global emissions.
