In recent times, environmental conservation has become a critical factor in the success of industries worldwide, particularly in the construction sector, which has a significant environmental footprint. In response, Green Supply Chain Management (GSCM) provides a strategic approach to integrating sustainability into procurement practices. This study proposes a structured framework for green procurement within GSCM, aligning sustainability principles with project management standards in accordance with ISO 10006:2017. A thorough literature review was conducted to identify main factors influencing green procurement. These factors were then refined through an open-ended questionnaire administered to industry professionals. Based on their feedback, a closed-ended questionnaire was developed and distributed to 73 experts in procurement and supply chain management. The responses were analyzed using a five-point Likert scale. The results identified the most influential factors for effective green procurement: quality control of material, certified supplier, purchasing non-toxic material, supplier audits, supplier selection, specifications for suppliers, purchasing eco-labeled material and suppliers must have ISO 14001 certification to take part in tenders. Based on these findings, a comprehensive framework was developed by linking each factor to the relevant project stakeholders and phases outlined in ISO 10006:2017. This framework aims to enhance procurement performance and promote sustainable, interoperable supply chain practices.
