Abstract：The carbon emissions of construction industry accounts for forty percent of global carbon emissions,and the magnitude and variation pattern of its carbon emissions have a significant impact on the achievement of the"dual carbon"goals.In order to clarify the carbon emission patterns of typical components in prefabricated buildings,this paper analyzes and studies the carbon emission patterns of six typical components of prefabricated building,including laminated slabs,exterior walls,interior walls,stairs,air-conditioning slabs and precast pavements in the production stage by using emission factor method.The results show that the carbon emissions generated by the consumption of raw mate-rials are the highest among the production stages of various typical prefabricated components,those generated by the consumption of energy are relatively lower,and the carbon emissions generated by construction workers are the lowest.In terms of the carbon emissions generated by the production of prefabricated components per unit of output and the carbon emissions generated by the consumption of materials therein,the order of magnitude is laminated slabs>exterior walls>air-conditioning slabs>interior walls>stairs>precast pavements.
