The construction industry emits a large amount of greenhouse gases every year, which significantly impacts the world's environment. Therefore, more and more researches focus on energy saving and emission reduction in building projects. The life cycle assessment method has occupied a dominant position in the environmental assessment of construction projects in recent years. This method can measure the environmental impact of any stage or the entire life cycle of a construction project. However, in the calculation process, researchers often do not pay attention to the calculation of carbon emissions of construction workers. Some studies directly ignore this factor, while more studies use per capita carbon emission values based on national data, which do not reflect the daily habits of construction workers. This study is based on the consumer lifestyle method, combined with the personal or household carbon emission calculator developed by the Hong Kong Environment and Ecology Bureau, and conducted field visits to investigate the actual habits and related data of construction workers in the four aspects of necessities of life in actual projects. After getting the per capita data of each item, bring it into the carbon emission calculator to get the per capita carbon emission considering the characteristics of construction workers. Finally, the data obtained in this study are brought into the previous related research, and it is found that the carbon emissions and proportion of workers have increased.
