Global CO2 Emissions from Fossil-Fuel Burning, Cement Manufacture, and Gas Flaring: 1752-2006

Figure 2: Global CO2 emissions from fossil fuel burning, cement manufacture, and gas flaring, 1751-2006. This graph shows combined emissions from all countries from 1751 to 2002, showing a sharp increase since the late 1800s.

Global Carbon Dioxide (CO2) emissions from fossil-fuels 1900-2008

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.
