Quantifying embodied emissions typically requires the use of GHG emission coefficients from life cycle assessment (LCA) databases. However, significant variability persists in the results of LCA studies while their underlying causes remain largely unexplored. Therefore, this research aims to compare embodied GHG emissions data of mass timber across five widely used LCA databases (Ecoinvent, AusLCI, EPiC, ICE, and ÖKOBAUDAT). Through detailed examination at material and building levels, the research reveals significant methodological inconsistencies that create substantial variations in embodied emissions. At the material level, mass timber emissions span from -686.80 to 1718.00 kgCO<sub>2</sub>eq/m<sup>3</sup>. Building-level analysis (A1-A3) reveals emission ranges of -170.31 to 434.62 kgCO<sub>2</sub>eq/m<sup>2</sup> for mass timber construction and 69.79 to 485.95 kgCO<sub>2</sub>eq/m<sup>2</sup> for concrete buildings. The study identifies several challenges in current mass timber LCAs, including inconsistent treatment of biogenic carbon flow, varying system boundary definitions, and inadequate consideration of End-of-Life (EoL) processes for mass timber. Regional variations in manufacturing processes, energy sources, and transportation distances emerge as essential factors influencing data quality. This highlights the need for establishing standardized approaches for biogenic carbon accounting, implementing detailed material documentation systems, and developing more comprehensive and transparent databases to enhance the reliability of mass timber LCA.</div></div>","PeriodicalId":21153,"journal":{"name":"Resources Conservation and Recycling","volume":"223 ","pages":"Article 108491"},"PeriodicalIF":11.2,"publicationDate":"2025-07-15","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144632093","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":1,"RegionCategory":"环境科学与生态学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

We identified universal scaling laws for urban population and residential building stock in a single city, and the building stock growth scaled superlinearly in most cities, with the scaling exponent ranging from 1.00 to 2.50; This growth pattern may exacerbate housing vacancy.

Temporally, the scaling exponents decreased with time in most sample cities. Additionally, the per capita carbon emissions during the material production stage of the urban vacant residential buildings of some cities (e.g., Shenyang, Harbin, Changchun, and Sining) with relatively large scaling exponents exceeded 3.00 tCO<sub>2</sub>/cap, and the revitalization of vacant houses is extremely important.
