Background: The transportation sector, a major part of logistics, significantly contributes to greenhouse gas emissions, making it a key environmental concern. As awareness grows, the importance of green logistics becomes evident. However, Small and medium logistics companies face challenges in implementing green logistics due to limited resources and knowledge. This study explores the post-adoption challenges SMEs encounter and identifies effective approaches for integrating sustainable methods. 

Purpose: The study explores green logistics practices within small and medium-sized enterprises (SMEs), addressing the gap between awareness and practical application of sustainable methods. The primary objective is to understand the operational challenges SMEs face after adopting green logistics practices and to identify effective strategies for their integration. Method: This study employs a qualitative interview approach with 10 interviews carried out with representatives from various small and medium logistics firms.

Conclusion: The study shows that small and medium logistics firms face several post-adoption challenges. The most significant challenge identified is the infrastructure limitation and accessibility, particularly concerning electric vehicles. SMEs are severely constrained by the lack of charging facilities for electric trucks during lengthy trips and the limited availability of alternative fuels. To support the integration of green logistics practices, the research also highlighted six key approaches employed by SMEs. The most significant approach is the development of specialized sustainability teams and promotion of employee involvement through educational programs.
