A FAIR CARBON SHARING MECHANISM FOR CONSTRUCTION PROJECTS: AN FDI CASE STUDY IN VIETNAM

Abstract

This paper presents a novelapproach to optimizing carbon emissions in construction projects through a project-based assessment framework. Set against Vietnam's commitment to achieving net-zero emissions by 2050, the study highlights the increasing importance of sustainable practices in the construction industry. By focusing on the critical decisions made by the owner, designer, and contractor, the approach provides a detailed understanding of how these choices impact the project's carbon footprint, cost, and schedule. Using a genetic algorithm in a case study of a foreign direct investment (FDI) project in Vietnam, the study generated solutions for a multi-objective optimization problem. Extensive discussions with stakeholders and a representative from the Ministry of Resources and Environment confirmed the approach's clarity, fairness, and potential for broader application. This study offers a foundational framework for project-based carbon assessment and optimization, providing actionable insights for stakeholders and contributing to the achievement of sustainable development goals. However, further refinement and validation are needed to enhance its applicability in real-world settings, paving the way for integration into future regulatory frameworks. This work underscores the necessity for dynamic and adaptable models to manage carbon emissions effectively in the construction sector.
