Abstract
This study explores the relationship between environmental management tools (EMTs) and sustainability performance of construction projects focusing on environmental, social, and economic dimensions. The study utilized a mixed methods approach. Data were obtained through the administration of questionnaires to project management professionals that work in construction. The study also analyses the case of the the Sawla-Maji Road Upgrading Project to offer a real-world perspective on the topic. Descriptive Statistics and correlation analysis were used to analyze the quantitative data whereas thermic analysis was used to analyze the documents and interview conducted to assess the case study. The research established that there are positive associations between EMT implementation and all three sustainability areas. The correlation analysis shows that there is a negative relation between EMTs and environmental performance indicators such as waste generation, resource consumption and pollution. The analysis also suggested a possible relationship between EMTs and social outcome. This connection was further solidified by the case study which provided evidence of a positive link with workers health and safety. Economically, EMTs seem to have a positive relationship with financial return and cost savings, though challenges like upfront costs require consideration. Overall, the paper adds to the current body of knowledge on the contribution of EMTs in sustainable construction. This research provides significant insights for practitioners, policy makers and researchers to utilize EMTs and its environmental, social, and economic sustainability benefits. Future research could explore EMT effectiveness across a wider range of project types and geographical contexts.
