ABSTRACT: This study examined the factors influencing the Omani Energy Efficiency Rating (EER) Program, with particular emphasis on the role of green supply chain practices. Structural Equation Modeling was employed using AMOS software to test the proposed research hypotheses and assess the impact of green supply chain dimensions on program effectiveness. A semi-quantitative, cross-sectional design was adopted. Data were collected from 19 employees representing 10 economic operators involved in the (EER) program. The study targeted senior and mid-level managers due to their role in strategic planning and policy development. Data were gathered through a self-administered electronic questionnaire and analyzed using AMOS software. The findings show that green supply chain practices are widely adopted and strongly interconnected; however, their effects on EER vary. Green Purchasing has a significant positive impact on EER, while Eco-design, Green Distribution, and Green Reverse Logistics exhibit weak or negative effects, and Green Manufacturing shows a negligible relationship. Overall, the model explains limited variance in EER, indicating the influence of additional factors. The study recommends strengthening and expanding the Energy Efficiency Rating Program through enhanced regulatory frameworks, broader product coverage, and the promotion of sustainable practices. These measures support national energy objectives and contribute to achieving Oman Vision 2040, the Paris Agreement, and the Sustainable Development Goals (SDGs).
