The exploitation and utilization of mineral materials during urban construction causes a large amount of carbon emission, but could also contribute to carbon sequestration. In the related literature, carbon sequestration process of building mineral materials has received limited attention and scientific quantification. On the basis of extracting building capacity and identifying building types, we used the technology of remote sensing image shadow height inversion to quantify mineral material consumption and carbon content parameters. Carbonization rate was measured by thermogravimetric analysis (TGA). Finally, a calculation method for carbon sink in urban buildings was constructed. We investigated the uncertainty of this method with Puhe New Town in Shenyang as an example. The results showed that the order of carbon sink density of different types of buildings followed the order of residential buildings > public service buildings > other types of buildings > commercial and financial buildings > industrial buildings; the ratio of carbon sink volumetric in diffe-rent types of construction land followed the order of commercial and financial buildings > residential buildings > public service buildings > other types of buildings > industrial buildings. The carbon sink calculation method based on the urban scale of building capacity in this study could quickly and accurately estimate the magnitude of carbon sinks from the inorganic materials in various types of urban construction lands. Under the background of limited urban natural carbon sequestration, using building carbon sequestration to enhance the urban carbon sequestration could provide new ideas for the low-carbon development of cities in China.
