Abstract
The importance of construction project environmental performance (CPEP) in the global sustainability drive has been acknowledged by scholars. However, the organizational related enablers of CPEP have not been explored exhaustively. To address this, this research analyzed the effect of top management green commitment (TMGC) on CPEP, the mediating role of green organizational culture (GOC) on the TMGC-CPEP relationship, and the moderating impact of TMGC on the link between GOC and CPEP. This study's data were collected face-to-face via a questionnaire survey of construction project managers and site managers in Nigeria using the probability sampling technique. A total of 278 useable responses were obtained, an 89% rate of response. The partial least-squares structural equation modeling approach (PLS-SEM) was used to analyze the study's data. The results of the study suggest that TMGC has a positive significant effect on CPEP, and GOC mediates the relationship between TMGC and CPEP. In addition, the relationship between GOC and CPEP is significantly moderated by TMGC, and the effect of GOC on CPEP increases when TMGC is high, and decreases when TMGC is low. This research's findings demonstrate the significance of TMGC and GOC in actualizing CPEP. Hence, regulators can better tailor laws and incentives to help companies make sustainability a top priority in their processes. Additionally, this study offers valuable insight regarding the mechanisms that can drive environmental sustainability within construction projects, which could be valuable to construction industry stakeholders.

N.B. Descriptive scope is a count of how many of the five facets of empirical research are indicated by the words used in title, abstract and keywords. It is not intended as a judgement on the research; merely a count of the kind of word we would expect to indicate Phenomenon, Concepts, Theoretical framing, Empirical techniques, Analytical techniques. If all five are present, then a code of “5 PCTEA” will indicate this. If you feel the coding for this record is questionable, we welcome discussion around the terms we matched or the way we categorized them. The facet you would expect may not be coded, or a facet may be coded inappropriately. This can also bear on a larger question, of which facets should be treated as defining in construction management research. Please get in touch, and we will look at it. More details here
