Abstract: Abstract Carbon emissions from the construction phase are highly concentrated and annual emissions are high, but the construction site environment is complex and difficult to calculate accurately. Besides, the accurate calculation of carbon emissions are the data base for exploring how to design and develop construction plans to control carbon emissions. In view of this, aiming at the building construction stage, this paper defined the spatial scope of carbon emissions calculation, took machinery and equipment as the calculation object, reorganized the calculation model from a spatial and temporal perspective, and proposed a method suitable for field measurement. The results of the study showed that the energy consumption data of the tower crane based on the quota data and rated power estimation were 126.64% and 160.54% higher than that measured by electricity meters respectively. The method of measurement using electricity meters is highly accurate and reflects the energy consumption on site. Therefore, when calculating carbon emissions from the construction site, it is necessary to adopt a more targeted calculation method based on construction machinery and equipment. What’s more, the research results provide some reference for the accurate acquisition and update of carbon emissions activity data from construction sites.
