The sustainable redevelopment of urban brownfields represents a complex interplay of socio-economic, environmental, and regulatory factors. This study addresses the research problem of quantifying the challenges inherent in the sustainable redevelopment process and hypothesizes that these challenges vary significantly across different domains such as governance, environmental impact, financial economics, technical operations, and legal regulations. Employing Partial Least Squares Structural Equation Modeling (PLS-SEM), the study aims to explore and quantify these challenges, providing actionable insights for policymakers and stakeholders. Focusing on brownfield projects within Chengdu's five urban districts, a survey was conducted spanning from November 1, 2023, to March 1, 2024, with a total of 436 respondents participating. Drawing upon an extensive dataset encompassing governance, environmental impact, financial economics, technical operations, and legal regulations, we provide a co.....

In recent years, the necessity of brownfield redevelopment has garnered increasing attention in academic literature. This paper employs a systematic review methodology to analyse current perspectives on brownfield sustainability, with a focus on dimensions, indicators, and stakeholders. Using the PRISMA (Preferred Reporting Items for Systematic Reviews and Meta-Analyses) methodology, this study systematically reviews 40 articles from the WoS and Scopus databases. The findings highlight a shift towards prioritising ecological resilience and cultural preservation, alongside traditional economic, environmental, and social dimensions. The complexity of sustainability indicators is discussed, emphasising their crucial role in assessing redevelopment success. The review also identifies key stakeholders, including governments, developers, and community groups, who prioritise these dimensions due to their impact on sustainable urban development and community well-being. Future research should .....
