摘要

This study investigates critical management factors influencing carbon emissions across building construction project (BCP) life cycles, specifically material manufacturing, transportation, and construction activities. Recognizing a research gap in developing economies, as previous models often relied on developed contexts, simulations, or lacked alignment with national decarbonization frameworks, this research focuses on Southeast Asia. Employing a mixed-methods design, including surveys of certified Thai Green Building Institute professionals, expert interviews, and a three-tiered statistical procedure culminating in exploratory factor analysis, the study empirically validates emission drivers in Thailand. Findings identify three critical components: material manufacturing, notably concrete and steel production, as the dominant factor; transportation, influenced by distance, fuel, and mode, as the second; and construction-site activities, particularly electricity and equipment operations, as the third. This tripartite structure validates emission drivers within Thailand’s national sustainability policy framework, offering twofold contributions. Methodologically, it statistically validates emission factors in a developing-country context, overcoming limitations of prior simulation-based or single-method studies. Applied value stems from aligning findings with Thailand’s 2050 carbon–neutral vision, generating transferable insights for other transitioning economies. Practically, the results recommend adopting low-carbon materials (e.g., SCMs, geopolymer concrete), optimizing logistics with cleaner transport, and implementing renewable energy on-site. These actionable strategies guide project managers and policymakers, aligning with SDGs 9, 11, 12, and 13.
