Table 1 to Subpart ZZ of Part 98—CO2 Emission Factors for Carbonate-Based Raw Materials

Carbonate Mineral name(s) CO2 emission
factor a		BaCO3Witherite, Barium carbonate0.223 CaCO3Limestone, Calcium Carbonate, Calcite, Aragonite0.440 Ca(Fe,Mg,Mn)(CO3)2Ankerite b0.408-0.476 CaMg(CO3)2Dolomite0.477 FeCO3Siderite0.380 K2CO3Potassium carbonate0.318 Li2CO3Lithium carbonate0.596 MgCO3Magnesite0.522 MnCO3Rhodochrosite0.383 Na2CO3Sodium carbonate, Soda ash0.415 SrCO3Strontium carbonate, Strontianite0.298

a Emission factors are in units of metric tons of CO2 emitted per metric ton of carbonate-based material.

b Ankerite emission factors are based on a formula weight range that assumes Fe, Mg, and Mn are present in amounts of at least 1.0 percent.
