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

Carbonate	Mineral name(s)	CO 2 emission factor a
BaCO3	Witherite, Barium carbonate	0.223
CaCO3	Limestone, Calcium Carbonate, Calcite, Aragonite	0.440
Ca(Fe,Mg,Mn)(CO 3)2	Ankerite b	0.408-0.476
CaMg(CO 3)2	Dolomite	0.477
FeCO3	Siderite	0.380
K2CO 3	Potassium carbonate	0.318
Li2CO 3	Lithium carbonate	0.596
MgCO3	Magnesite	0.522
MnCO3	Rhodochrosite	0.383
Na2CO 3	Sodium carbonate, Soda ash	0.415
SrCO3	Strontium carbonate, Strontianite	0.298

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.
