The move towards green construction concepts' implementation in road construction provides an opportunity to reduce the carbon footprint while enhancing the prowess of the built environment to uphold sustainability. The purpose of this study is to identify the CSFs for the adoption of green construction concepts in the road construction sector. Through a thorough literature review and pre-testing, 20 CSFs for green construction concepts adoption in road construction were identified. A mean score ranking was used to rank the CSFs for adopting green construction concepts in road construction. At the same time, an analysis of variance (ANOVA) was run to test for significant differences in perceptions among the respondents. Exploratory factor analysis was further used to ascertain the connection among the variables. The findings of the study revealed the following four CSFs in the adoption of green construction concepts in road construction: 'collaboration and tendering requirements', 'regulatory factor', 'leadership and standards development', and 'bridging industry and academia gap'. The study is known to serve as a practical reference to help adopt green construction concepts in road infrastructure projects. [ABSTRACT FROM AUTHOR]
