GLOBAL EMISSION BY COUNTRY

GLOBAL EMISSION BY COUNTRY

Line graph of global carbon dioxide emissions from fossil fuels for 1900 through 2008. The line graph shows a slow increase from about 2,500 teragrams of carbon dioxide emissions in 1900 to about 5,000 teragrams of carbon dioxide emissions in 1950. After 1950, the increase in carbon dioxide emissions is more rapid, reaching approximately 32,000 teragrams of carbon dioxide in 2008.

Global carbon emissions from fossil fuels have significantly increased since 1900. Emissions increased by over 16 times between 1900 and 2008 and by about 1.5 times between 1990 and 2008.
“Emissions of non-CO2 greenhouse gases have also increased significantly since 1900. To learn more about past and projected global emissions of non-CO2 gases, please see the EPA (Environment Protection Agency )report.

2008 Global CO₂ Emissions from Fossil Fuel Combustion and some Industrial Processes (million metric tons of CO₂)

Pie chart that shows country share of greenhouse gas emissions. 23 percent comes from China; 19 percent from the United States; 13 percent from the EU-27 (excluding Estonia, Latvia, and Lithuania); 6 percent from India; 6 percent from the Russian Federation; 4 percent from Japan; 2 percent from Canada; and 28 percent from other countries.

In 2008, the top carbon dioxide (CO₂) emitters were China, the United States, the European Union, India, the Russian Federation, Japan, and Canada. These data include CO₂ emissions from fossil fuel combustion, as well as cement manufacturing and gas flaring. Together, these sources represent a large proportion of total global CO₂ emissions.
Emissions and sinks related to changes in land use are not included in these estimates. However, changes in land use can be important - global estimates indicate that deforestation can account for 5 billion metric tons of CO₂ emissions, or about 16% of emissions from fossil fuel sources. Tropical deforestation in Africa, Asia, and South America are thought to be the largest contributors to emissions from land-use change globally.In areas such as the United States and Europe, changes in land use associated with human activities have the net effect of absorbing CO₂, partially offsetting the emissions from deforestation in other regions.
