Abstract: A comparative cradle-to-gate life cycle assessment is carried out on three different metal-organic frameworks. MOF-1 is TCM 14 consisting of 4,4′-azopyridine auxiliary ligands, dinuclear copper (II) based secondary building units, acetylene-extended and tritopic benzoate linkers. MOF-2 consists of zeolite A, 40% diethylenetriamine and methanol. MOF-3 consists of zeolite 13X, 40% diethylenetriamine and methanol. Several environmental impact categories are selected to represent a comprehensive view. The global warming potential for MOF 1, 2, and 3 is found to be 3.5, 14.1, and 13.9 kg CO₂ eq/kg MOF produced, respectively. A sensitivity analysis of varying amines is also carried out.

Keywords: carbon management; environmental impact; sorption; sustainability.
