CDIAC's database of carbon dioxide emissions from fossil-fuel combustion and cement production (NDP-030/R8) has been extended and updated. This database provides quantitative estimates of annual CO2 emissions from fossil-fuel combustion and cement production through 1995, with global total emissions for each year and some national estimates beginning in 1751. The global total emissions rose from 3 million metric tons C in 1751 to 6412 million metric tons C in 1995.
Estimates of post-1950 emissions are derived primarily from energy statistics published by the United Nations (UN) and are calculated using the methods of Marland and Rotty (1984). The UN data have now been supplemented by other data that provide comprehensive national estimates on fuel production and trade prior to 1950. Cement production estimates (beginning in 1928) from the U.S. Department of Interior's Bureau of Mines are used to estimate CO2 emitted during cement production. Emissions from gas flaring (beginning in 1950) are determined primarily from UN data but are supplemented with data from the U.S. Department of Energy's Energy Information Administration, Rotty (1974), and a few national estimates interpolated by Marland.
This database was produced by CDIAC's Gregg Marland, Tom Boden, and Antoinette Brenkert, Bob Andres of the University of Alaska-Fairbanks; and Cathy Johnston of The University of Tennessee-Knoxville. It is accessible via CDIAC's Web site at http://cdiac.esd.ornl.gov/ndps/ndp030.html.
