PurposeConstruction firms worldwide are increasingly taking pragmatic steps towards addressing environmental problems arising from their activities. Nonetheless, there is a paucity of studies focused on the nexus between green construction and environmental performance. Hence, this study aims to examine the linkages between green construction practice and environmental performance.Design/methodology/approachAn extensive literature review was conducted to identify the relevant dimensions of green construction practice and indicators for measuring environmental performance. Variables collated were then subjected to pre-assessment and pre-testing processes. The pre-assessment was used as a preliminary content validation where experts assessed the various dimensions of green construction practice and indicators for measuring environmental performance proposed and determine if indeed the variables represent what the study set out to measure. Data were collected from construction professionals within the Ghana's Kumasi Metropolis. The sample size for the study was 100 experts in sustainable construction methods in the construction industry. A total of 63 responses were received out of the 100 target respondents, accounting for a 63% response rate. Data generated was analysed using mean score analysis and one-sample t-test to determine the level of significance of the various green construction practices and indicators for measuring environmental performance. A Pearson correlation analysis was undertaken to ascertain the relationships that exist among the various dimensions of green construction practice and indicators for measuring environmental performance. Finally, multiple linear regression analysis was utilised to ascertain the effect of the adoption of green construction practice on environmental performance.FindingsThe results indicate that all the green construction practices and the indicators of environmental performance identified from the literature were significant at p = 0.05. The study's findings revealed that energy management is the most significant construct of green construction practice followed by storm-water management. Furthermore, the analysis showed that the preservation of water is the most significant environmental performance indicator followed by sanitation. The regression model developed also explained that 75% of the variations in environmental performance are explained by green construction practice.Research limitations/implicationsNotwithstanding the study's achievements, one major limitation the research faced was the relatively small sample size.Practical implicationsThis study provides sufficient data for construction professionals to identify the various green construction practices that could enhance environmental performance. The study's results showed that environmental performance could be improved by adopting the key green construction practices identified in this study. Pragmatic directions are also provided to stakeholders in the construction industry to take a critical look at the environmental performance indicators that were significant.Originality/valueThis pioneering research attempts to investigate the linkages between green construction practice and environmental performance in Ghana. Key results provide a critical evidential influence of green construction on environmental performance and make a crucial contribution to the current body of knowledge.
