ABSTRACT
As global climate change becomes increasingly severe, carbon emissions from building materials have emerged as a critical challenge for the construction industry's low-carbon development. This study examines the carbon emissions of building materials from a full life-cycle perspective, systematically analyzing their current status and influencing factors, and proposes a carbon emission calculation model based on multi-source data fusion and machine learning algorithms to enhance the accuracy and efficiency of carbon emission assessments. Typical building materials, such as concrete, steel, and wood, were selected as case studies to compare the impacts of different production technologies, transportation methods, and recycling strategies on carbon emissions, thereby exploring feasible pathways for the low-carbon development of building materials. The results indicate that optimizing production processes, improving material recycling rates, and promoting renewable materials are effective means to reduce carbon emissions from building materials. Additionally, this study innovatively incorporates regional environmental adaptability analysis, integrating specific climatic conditions and socio-economic characteristics to propose location-specific low-carbon development strategies. The research demonstrates that through the implementation of comprehensive measures, carbon emissions from building materials can be significantly reduced by 20%-35%, providing crucial references for the sustainable development of the construction industry. Overall, this study not only refines the quantification evaluation system for carbon emissions from building materials but also offers scientific evidence and technical support for policymakers and industry practitioners, highlighting its significant theoretical value and practical application implications.
