Impact of green supply chain management practices on the triple bottom line: a study on apparel manufacturers of Sri Lanka.

Purpose: This paper aims to assess the impact of green supply chain management (GSCM) practices on the triple bottom line's economic, social and environmental performance of Sri Lankan apparel manufacturers. Design/methodology/approach: This quantitative study uses a deductive approach. The practice-based view is used to support the conceptual framework. The partial least square structural equation modelling technique empirically assessed the conceptual model using 164 responses from Sri Lankan apparel manufacturers through a structured survey questionnaire. Apart from examining the direct effects of GSCM practice on the triple bottom line, the study also investigated the moderating effects of firm size and duration. Findings: The results show that GSCM practices positively affect the organisation's triple bottom line while business size and duration moderate the said relationship. Research limitations/implications: The fact that this study is based on Sri Lankan apparel producers may impact the generalizability of the findings across different industries and countries. Furthermore, the survey only looked at export manufacturers. This raises questions about the results' relevance to other non-export groups of the current population with distinct characteristics. Practical implications: The paper provides insights for both academia and practitioners on the importance of adopting GSCM practices for the business performance of apparel manufacturers in Sri Lanka. The paper includes implications for devising strategic solutions for organisational performance and sustainability by using GSCM practices in apparel manufacturers in Sri Lanka. Originality/value: The research contributes to the body of knowledge in the GSCM field in general. This research also contributes to the limited literature on GSCM practices in Sri Lanka. To the best of the authors' knowledge, this is the first attempt to explain how apparel manufacturers in Sri Lanka are organised. [ABSTRACT FROM AUTHOR]
