Global, Regional, and National Annual CO2 Emissions from Fossil-Fuel Burning, Cement Production, and Gas Flaring: 1751-2006 (revised May 2009)

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.
