The objective of this study is to identify the factors influencing the adoption of sustainable procurement practices in Egypt's public sector. The study specifically aimed to assess the impact of Perceived Cost, Staff Involvement, Top Management Support, and Organizational Culture on the adoption of these practices. A conceptual framework was developed to guide the research. Both qualitative and quantitative approaches were used to gather data. For the qualitative approach, the researchers reviewed relevant literature and conducted exploratory research, including interviews with four managers and one quality assurance professional from an Egyptian public organization (Kader Factory for Advanced Industries). In the quantitative phase, a self-administered questionnaire using a five-point Likert scale was developed and distributed to 292 employees. The data were analyzed using SPSS version 26 and AMOS version 26. Structural Equation Modeling (SEM) was employed to assess the best-fit measurement model and examine causal relationships among the variables.

The findings indicated that Perceived Cost, Staff Involvement, Top Management Support, and Organizational Culture significantly influence the adoption of sustainable procurement practices in the public sector. The study recommended focusing on lifecycle costs despite higher initial expenses, implementing structural and organizational changes to support green procurement, enhancing staff awareness and involvement, and promoting an organizational culture that fosters sustainable practices. Additionally, it emphasized the need for periodic review of existing policies to ensure they remain relevant and up-to-date.
