Abstract
<p><em>This study examined the relationship between green supply chain management (GSCM) practices and marketing effectiveness in pharmaceutical firms in Port Harcourt, Nigeria. The primary objective was to determine how GSCM practices influence marketing effectiveness, measured through brand awareness and corporate image. The study population consisted of 217 registered pharmacies listed in the Nigerian Stock Exchange Facts Book (2014).

Findings indicate that implementing green procurement, green manufacturing, and other environmentally sustainable supply chain practices enhances brand awareness and strengthens corporate image. The study concludes that integrating GSCM practices is critical for improving marketing outcomes in pharmaceutical firms.
