Prefabricated Construction (PC) Technology is recognized for its advantages in reducing carbon emissions, lowering energy consumption, conserving materials, and improving waste management. Despite significant research efforts, few systematic analyses have been conducted to consolidate the current understanding of carbon emissions in PC. To address this gap, the present study undertakes a comprehensive review using a synergistic approach that integrates scientometric and rigorous qualitative analyses. The aim is to synthesize state-of-the-art research on carbon emissions in PC and provide insightful directions for future academic work in this field. A database of 114 relevant journal articles was compiled through a meticulous data collection process, followed by scientometric analysis to map influential journals, key articles, active countries, and emerging research trends. The qualitative analysis identifies prevailing research domains, highlights critical research gaps, and anticipates future needs. This study contributes to enriching the existing knowledge base and offers both theoretical insights and practical guidance for advancing low-carbon construction, optimizing assessment frameworks, and promoting interdisciplinary collaboration and informed policymaking.
