The integration of sustainability metrics into procurement and vendor management has become a critical priority for organizations aiming to balance economic performance with environmental stewardship and social responsibility. This proposes a conceptual framework designed to systematically incorporate environmental, social, and governance (ESG) criteria into procurement processes and vendor evaluation. Drawing from a comprehensive review of existing literature, the framework addresses the growing demand for transparency, accountability, and ethical considerations within supply chains. The framework emphasizes a multidimensional approach to supplier assessment, combining traditional procurement factors such as cost, quality, and delivery with robust sustainability indicators. Key sustainability metrics include carbon footprint reduction, resource efficiency, labor practices, community impact, and corporate governance standards. These metrics are weighted and integrated through a structured decision-making process to enable holistic evaluation and ranking of suppliers. Technological enablers such as enterprise resource planning (ERP) systems, blockchain, and Internet of Things (IoT) devices are incorporated into the framework to facilitate real-time data collection, validation, and transparency. Advanced data analytics support predictive insights and continuous monitoring, allowing organizations to adapt their procurement strategies dynamically in response to evolving sustainability challenges. Implementation considerations, including organizational change management, stakeholder engagement, and data integration challenges, are discussed to provide practical guidance for adoption across diverse industrial sectors. The framework’s flexibility allows for customization to specific industry contexts and regulatory environments, ensuring relevance and effectiveness. The proposed framework aims to enhance supplier collaboration, foster innovation in sustainable practices, and mitigate risks related to environmental compliance and reputational damage. By embedding sustainability deeply into procurement and vendor management, organizations can improve their overall supply chain resilience and contribute meaningfully to global sustainability goals. This conceptual contribution lays the groundwork for future empirical validation and expansion into lifecycle and circular economy assessments.
