Abstract

The rapid expansion of railway infrastructure construction projects in Thailand plays a crucial role in supporting sustainable national development. However, the construction phase is recognized as a major contributor to carbon dioxide (CO₂) emissions. This study aims to investigate and analyze project management factors that contribute to CO₂ emission reduction in railway infrastructure construction projects in Thailand. A quantitative research approach was employed. Based on an extensive literature review, 27 project management variables were identified and incorporated into a five-point Likert scale questionnaire. Data were collected from 407 practitioners involved in railway infrastructure construction projects and analyzed using descriptive statistics and Exploratory Factor Analysis (EFA). The results reveal that the extracted factors explain a total variance of 70.538% and can be classified into four principal components: (1) Project Planning and Management Approaches, (2) Site and Resource Management, (3) Personnel and Stakeholder Readiness, and (4) Standards and Operational Control. The findings indicate that strategic planning, managerial support, stakeholder cooperation, and systematic operational control play a significant role in reducing CO₂ emissions during the construction phase. This study provides practical and policy-relevant insights for enhancing project management practices in railway infrastructure construction, thereby supporting sustainable carbon emission reduction and long-term infrastructure sustainability in Thailand.
