Abstract：As the“dual carbon”goals continue to advance, embodied carbon has increasingly emerged as a core issue in the construction sector, drawing growing attention. Focusing on floor systems as an entry point, this study synthesizes carbon reduction mechanisms across three levels—micro-scale materials, meso-scale components, and macro-scale systems—through an extensive literature review and case analysis. It also clarifies the shifts in calculation timeframes and spatial-temporal perspectives. Using hybrid-material floor systems in mass timber structures as an example, the paper further discusses key design strategies for each of these three levels. Finally, it points out that the expanding boundaries of the broader ecosystem and the integration of whole-life-cycle processes present both opportunities and challenges for carbon reduction. Centered on the goal of lowering embodied carbon in construction, this research aims to promote the green and low-carbon development of architectural design.
