Carbon dioxide (CO 2) emissions from energy and material production can arise from various sources and fuel type: coal, oil, gas, cement production and gas flaring.. As global and national energy systems have transitioned over centuries and decades, the contribution of different fuel sources to CO 2 emissions has changed both geographically and temporally.
Coal combustion products (CCP's) are the solid residues generated by coalburning electric utilities in the production of electricity. In 1998, electricity accounted for about 35% of the primary energy use in the United States and was produced by electric power generators designed to convert different fuel types into electricity. More than onehalf of the electricity in the
These savings could be increased by the use of more alternative fuels (Nielsen and Glavind, 2007) (to coal, which actually accounts for 60% of the fuel used in cement production). Use of SCMs The use of SCMs in concrete is different from using them to produce blended cements.
