Several industries start focusing on the green concept in supply chain management (SCM) to reduce waste, emission and to preserve the quality of natural resources. However, it is still very difficult to understand and analyze the effect of individual activities of green supply chain and their corresponding contribution. Therefore, the purpose of this study is to investigate the impact of green supply chain management on organizational performance. This study is a conceptual review based on existing literatures in the area of green supply chain management. Efforts were made to examine the impact of reverse logistic, green procurement, green distribution as a component of GSCM on organizational performance in the area of manufacturing and logistics firms in Nigeria. Based on critical literature review conducted, the existing literature on the effects of green supply chain management practices on firm performance provides support for the idea that there is a positive relationship between GSCM practices and firm performance. They also enhance the understanding of how different types of GSCM practices are related to financial, operational and environmental performance in manufacturing and logistics. The empirical results suggest that while internal GSCM practices have the strongest effect on environmental performance, environmental collaboration with customers seems to be the most effective way to improve financial performance. In terms of operational performance, most findings were more mixed, suggesting that the operational performance of firms is more likely to be affected by firm characteristics than by the choices they make regarding their environmental collaboration.
