Compared to data of CO2 saturation in NaCl aqueous solution, data on the solubility of CO2 in CaCl2 solutions are scarce. In this work, a new analytical method was developed to measure the CO2 solubility in calcium chloride solution. This method relies on conductimetric titration coupled with pH measurement. Saturation data of CO2 in a 1 mol/kgw CaCl2 solution in the pressure range from 1 to 20 MPa and between 323.15 and 423.15 K were acquired
