Developing a multi-tiered decision-making framework for screening fdi construction projects in Vietnam: Integrating lean, green, and circular approaches toward Net-Zero 2050

Tóm tắt

Vietnam's pledge to attain net-zero emissions by 2050 requires effective strategies to assess the sustainability of foreign direct investment (FDI) construction projects.  This study introduces a multi-tiered decision-making framework that integrates lean construction, green building, and circular economy ideas into a unified assessment tool.  Eight pilot FDI projects, representing four primary FDI categories: Food & Beverage Processing Facilities, Electronics & Tech Manufacturing Plants, High-Rise Residential/Mixed-Use Buildings, and Commercial/Industrial Parks, are used to deduce weights in multiple linear regression.  Three other projects were assessed to verify the framework's prediction precision.  Results demonstrate that elevated index scores are associated with enhanced resource efficiency, reduced carbon footprints, and superior waste management techniques.  A tier classification system (Platinum, Gold, Silver, Bronze) provides explicit benchmarks for politicians and investors, aiding in the allocation of incentives and promoting ongoing enhancement.  This approach customizes lean, green, and circular tactics to local contexts, aligning foreign direct investment projects with Vietnam's decarbonization path and offering a pragmatic model for evaluating construction proposals in developing countries.
