AB  - We report measurements of the solubility of CO<inf>2</inf> in aqueous potassium glycinate and of the density of the solution with and without CO<inf>2</inf> loading. The CO<inf>2</inf> solubility was measured with a bespoke static-synthetic vapour liquid equilibrium (VLE) apparatus, while densities were measured with a high-pressure vibrating-tube densimeter. The VLE apparatus was validated by means of measuring the solubility of CO<inf>2</inf> in a 7 mol·kg<sup>-1</sup> aqueous ethanolamine solution, and the results were in good agreement with the literature. Three molalities of aqueous potassium glycinate were studied: (1, 2 and 3) mol·kg<sup>-1</sup>. The CO<inf>2</inf> solubility measurements were made at temperatures between (313.15 and 393.15) K with pressures up to 0.65 MPa, while the density was measured at temperatures between (298.15 and 393.15) K with pressures up to 10 MPa.
