Note: This version
of the fossil-fuel CO2
emissions database replaces previous versions of the same database.
Users should replace earlier versions since estimates prior to 2006 may have changed.
For those needing earlier published versions, please contact CDIAC. Earlier versions
of the fossil-fuel CO2 emissions database are
archived at CDIAC, but not available on-line.
Global, regional, and national annual estimates of CO2
emissions from fossil fuel burning, cement production, and gas flaring have been calculated
through 2006, some as far back as 1751. These estimates, derived primarily from energy
statistics published by the United Nations, were calculated using the methods of Marland
and Rotty (1984). Cement production estimates from the U.S. Department of Interior's
Bureau of Mines were used to estimate CO2 emitted during
cement production. Emissions from gas flaring were derived primarily from U.N. data but
were supplemented with data from the U.S. Department of Energy's Energy Information
Administration, Rotty (1974), and with a few national estimates provided by G. Marland.
