Research on Carbon Emission Accounting for the Whole Life Cycle of Industrial Buildings in Shaanxi Province

In recent years， China has vigorously promoted the new industrialization process， and the construction and operation of industrial buildings have generated a large amount of carbon dioxide. In order to achieve the “dual carbon” goals， the research on the carbon emission accounting method for industrial buildings has been carried out， and three types of building-area-splitting methods have been proposed. Based on the whole life cycle theory， a provincial-level building carbon emission accounting model was established. Taking the industrial buildings in Shaanxi Province as the research object， the carbon emissions at each stage of the life cycle assessment were calculated. The results showed that from 2004 to 2021， the carbon emissions of industrial buildings in Shaanxi Province showed an upward trend， reaching 10.0423 million tons in 2021； among them， the carbon emissions at the material production stage and the building operational stage accounted for the largest proportion. The production of steel and cement was the main component of carbon emissions at the material production stage， each accounting for approximately 39%； the consumption of electricity， raw coal， heat， and natural gas was the main source of carbon emissions at the building operation stage， among which electricity contributed the most， accounting for 38.99% of the carbon emissions at the building operational stage.
