Sustainable Construction Practices in Bangkok: Reducing Carbon Emissions in Urban Infrastructure Projects

Objectives: This research aimed to examine the impact of various factors on sustainable construction practices (SCP) within Bangkok’s construction industry, focusing on regulatory influence, cost implications, stakeholder commitment, and carbon emission reduction. Methods: The study employed Structural Equation Modeling (SEM) to analyze both direct and indirect effects of these factors on SCP. Carbon emission reduction was specifically investigated as a mediating factor that amplified the influence of regulatory policies on SCP. Results: The findings revealed that regulatory influence played a significant role in promoting SCP. It had both direct and mediated effects on SCP, which were stronger than the impacts of cost implications and stakeholder commitment. The developed model integrated environmental, economic, and stakeholder factors, offering insights tailored to Bangkok’s unique regulatory and socio-economic context. Conclusion: The study concluded that robust regulatory frameworks, when combined with effective stakeholder engagement, are essential for supporting sustainable practices in urban construction. These results provide valuable guidance for policymakers and industry leaders working to promote sustainability in Bangkok’s rapidly growing infrastructure sector.
