List of countries by carbon dioxide emissions

This is a list of sovereign states by carbon dioxide emissions due to human activity. The data presented below corresponds to emissions in 2004. The data itself was collected in 2007 by the CDIAC for United Nations. The data considers only carbon dioxide emissions from the burning of fossil fuels, but not emissions from deforestation, and fossil fuel exporters, etc.

These statistics are rapidly dated due to huge recent growth of emissions in Asia. The United States is the 10th largest emitter of carbon dioxide emissions per capita as of 2004. According to preliminary estimates, since 2006 China has had a higher total emission due to its much larger population and an increase of emissions from power generation. China is the 91st largest emitter of carbon dioxide emissions per capita as of 2004.

Some dependencies and territories whose independence has not been generally recognized are also included, as they are in source data.

Certain entities are mentioned here for purposes of comparison. These are indicated in italics and are not counted in the ordering of sovereign states. (See also: carbon cycle)
