Governments across the world are taking actions to address the high carbon emissions associated with the construction industry, and to achieve the long-term goals of the Paris Agreement towards carbon neutrality. Although the ideal of the carbon-emission reduction in building projects is well acknowledged and generally accepted, it is proving more difficult to implement. The application of building information modeling (BIM) brings about new possibilities for reductions in carbon emissions within the context of sustainable buildings. At present, the studies on BIM associated with carbon emissions have concentrated on the design stage, with the topics focusing on resource efficiency (namely, building energy and carbon-emission calculators). However, the effect of BIM in reducing carbon emissions across the lifecycle phases of buildings is not well researched. Therefore, this paper aims to examine the relationship between BIM, carbon emissions, and sustainable buildings by reviewing and assessing the current state of the research hotspots, trends, and gaps in the field of BIM and carbon emissions, providing a reference for understanding the current body of knowledge, and helping to stimulate future research. This paper adopts the macroquantitative and microqualitative research methods of bibliometric analysis. The results show that, in green-building construction, building lifecycle assessments, sustainable materials, the building energy efficiency and design, and environmental-protection strategies are the five most popular research directions of BIM in the field of carbon emissions in sustainable buildings. Interestingly, China has shown a good practice of using BIM for carbon-emission reduction. Furthermore, the findings suggest that the current research in the field is focused on the design and construction stages, which indicates that the operational and demolition stages have greater potential for future research. The results also indicate the need for policy and technological drivers for the rapid development of BIM-driven carbon-emission reduction.
世界各地的政府都在采取行动，以解决建筑行业与高碳排放相关的问题，并实现《巴黎协定》关于碳中和的长期目标。虽然减少建筑项目碳排放的理念得到了广泛认可，但实际实施起来却更加困难。建筑信息模型（BIM）的应用为可持续建筑的碳减排带来了新的可能性。目前，与碳排放相关的 BIM 研究主要集中在设计阶段，主题集中在资源效率上（即建筑能源和碳排放计算器）。然而，BIM 在减少建筑物全生命周期阶段的碳排放方面的效果尚未得到充分研究。因此，本文旨在通过回顾和评估 BIM 与碳排放领域的研究热点、趋势和差距，考察 BIM、碳排放与可持续建筑之间的关系，为理解现有知识体系提供参考，并有助于激发未来的研究。本文采用文献计量分析的宏观定量和微观定性研究方法。结果表明，在绿色建筑施工、建筑生命周期评估、可持续材料、建筑能源效率和设计以及环境保护策略方面，BIM 在可持续建筑碳排放领域是最受欢迎的五个研究方向。有趣的是，中国在利用 BIM 减少碳排放方面表现出了良好的实践。此外，研究结果表明，目前该领域的研究主要集中在设计和施工阶段，这表明运营和拆除阶段有更大的研究潜力。研究结果还表明，需要政策和技术驱动因素来促进 BIM 驱动的碳减排的快速发展。
