Abstract：This paper researched the building life cycle carbon footprint based on a representative modern timber building in China, and a method of splitting the carbon emission of negative carbon building materials into the carbon emission of the production process and the biological carbon sequestration value was proposed. The results showed that the carbon emissions of the life cycle of the modern timber office building were 1.69×107kgCO2e, in which the product stage accounted for 15.56%, the use stage accounted for 84.34%, and the end-of-life stage accounted for 0.10%. The carbon emission in the product stage of timber building was lower than that of traditional reinforced concrete or steel buildings.
