Abstract:
Purpose: Growing global attention on the environment has resulted in a shift towards 
eco-friendliness and Findings the best feasible solution to go "green" in the past few 
decades. Green Supply Chain Management (GSCM) is a revolutionary management 
approach, generating sustainability in business activities by reducing environmental 
impact and increasing ecological efficiency. However, as the world progresses and 
individuals become more aware of their environmental responsibilities, steps have 
been taken to reduce their adverse environmental effects.
Methodology: This study aims to investigate the effect of GSCM practices on 
sustainability performance in the Sri Lankan apparel sector. Green procurement, green 
manufacturing, green design, and green distribution were identified as GSCM practices 
and sustainable performance was measured using environmental, social and economic 
performance. The survey questionnaires from 70 large scale apparel Sri Lankan 
companies confirmed that GSCM practices significantly impact on sustainability 
performance. 
Findings: Green procurement, green design, and green manufacturing, rather than 
green distribution, significantly impact on sustainability performance. All GSCM 
practices should be combined to improve strong sustainability performance and they 
require strong cooperation from all the elements of the supply chain. 
Implementations: All GSCM practices should be combined to improve strong 
sustainability performance and they require strong cooperation from all the elements of 
the supply chain.
