Cement - GHG Information

This section provides various sources describing the energy consumption of the industrial sector and the carbon emissions in particular. Below is an estimate of the emissions expressed in million metric tons of carbon equivalents (MMTCE) based upon the Annual Energy Outlook 2003.

According to EIA "Annual Energy Outlook 2003" data, energy-related CO2 emissions for the cement industry were 8.3 MMTCE in 2002, and process-related CO2 emissions were approximately 11.4 MMTCE for a total of 19.7 MMTCE.

(The AEO Supplementary tables were generated for the reference case of the Annual Energy Outlook 2003 using the National Energy Modeling System, a computer-based model which produces annual projections of energy markets for 2000-2025. The AEO2003 reflects data and information available as of August 30, 2002.)

In addition, a recent report, Energy Efficiency Improvement and Cost-Saving Opportunities for Cement Making, an ENERGY STAR® Guide for Energy and Plant Managers, by the Ernest Orlando Lawrence Berkeley National Laboratory (in preparation) utilized actual survey data supplied by the industry to the U.S. Geological Survey. Based on the survey data, it reports total cement industry emissions to be 22.3 MMTCE; 10.7 MMTCE from process emissions, 11.6 MMTCE from energy-related emissions, including emissions from power generated elsewhere but used in cement plants for 1999.
