Background: In the face of escalating climate change concerns, Corporate Environmental Management has transitioned from a voluntary philanthropic activity to a strategic necessity. Green innovation is increasingly viewed as the operational mechanism through which environmental commitments are actualized.

Objective: This study aims to evaluate the impact of Green Supply Chain Management (GSCM) practices on Corporate Environmental Performance (CEP), with Green Innovation acting as a mediating variable.

Method: This study uses a simulated dataset created for academic training purposes. Data representing 280 middle-to-senior level supply chain managers was simulated. Partial Least Squares Structural Equation Modeling (PLS-SEM) was applied using SmartPLS software.

Key Results: GSCM practices positively and significantly influence Green Innovation (β = 0.62, p < 0.001) and CEP (β = 0.34, p < 0.001). Green Innovation significantly enhances CEP (β = 0.48, p < 0.001) and fully mediates the relationship between GSCM and CEP.
