建筑行业在我国占总碳排放一半以上，其减排有利于“双碳”目标的实现。本研究以山西省为例分析其建筑碳排放特征并探讨减排路径，结果表明山西省建筑间接碳排放占比超95%，其中工业领域占总建筑碳排放的80%以上，过去20年碳排放强度下降超过78%，但仍高于全国水平，因此山西省建筑减排应走全生命周期低碳设计、建材生产低碳转型和施工环节电动化、绿能化之路。这一研究为山西省建筑减排政策制定提供理论依据，并为中西部其他地区建筑减排相关政策制定提供参考。

As a key field of carbon emissions, the building industry plays a crucial role in achieving the “dual carbon”goals through emission reduction. Taking Shanxi Province as the research object, characteristics of carbon emissions, and explores emission reduction paths were analyzed. The results showed that: indirect carbon emissions account for more than 95%, with the industrial sector contributing 80%; although the carbon emission intensity has decreased by more than 78%, it is still higher than the national average. Based on these findings, paths such as full life-cycle low-carbon design, low-carbon transformation of building materials production, and “electrification + green energy” in the construction phase are proposed. This study provides a basis for formulating building emission reduction policies in Shanxi Province and a reference for related research in central and western regions.
