Summary:[Display omitted] •Twelve new restoration mortar using various binders were assessed using LCA.•Assessed impact categories include global warming, smog formation and acidification.•Hydraulic lime binders perform best in most environmental impacts. Twelve experimental restoration mortars were formulated using air lime, hydraulic lime or Portland cement as binders. A cradle-to-grave life cycle assessment was used to quantify the potential environmental impacts on the categories of global warming potential, abiotic resources depletion potential-fossil fuels, acidification potential, and the photochemical oxidants creation potential of mortars. Hydraulic lime binders perform better in all evaluated environmental impacts. The global warming potential of the mortars are in the range of 472–737 kg CO2-eq/t. The critical hot spots are the transport model assumptions, and the fuel used for the binder production; using natural gas instead of mineral coke may reduce the global warming potential between 14 and 22 %, depending on the type of binder.
