Carbonate	Mineral name(s)	CO₂ emission factor ^a
BaCO₃	Witherite, Barium carbonate	0.223
CaCO₃	Limestone, Calcium Carbonate, Calcite, Aragonite	0.440
Ca(Fe,Mg,Mn)(CO₃)₂	Ankerite ^b	0.408-0.476
CaMg(CO₃)₂	Dolomite	0.477
FeCO₃	Siderite	0.380
K₂ CO₃	Potassium carbonate	0.318
Li₂ CO₃	Lithium carbonate	0.596
