There is an increasing interest in assessing the environmental impacts of construction materials and their components in recent years. By considering these environmental impacts, the selection of suitable construction materials and technology is crucial for satisfying user needs and minimizing environmental impacts. The aim of this study is to compare the environmental impacts of precast concrete wall and brick wall production with cradle to gate approach by using Life Cycle Assessment (LCA) approach. In this study, LCA was applied based on ISO 14040 and 14044 by using SimaPro 9.2 software. CML-IA baseline method and Ecoinvent database was used for the life cycle impact assessment. The obtained results revealed that brick wall has better environmental performance than precast concrete wall in all impact categories except abiotic depletion and marine aquatic ecotoxicity. The global warming potential of the precast concrete and brick wall per m2 were calculated as 2.35E+02 kg CO2 eq. and 2.10E+02  kg CO2 eq, respectively.
