Sustainable procurement integrates environmental, social, and economic considerations into purchasing decisions to minimize negative impacts and promote long-term resource efficiency. It emphasizes sourcing goods and services that are eco-friendly, ethically produced, and socially responsible, thereby supporting sustainable development goals. Technical architecture in this context refers to the structured framework and systems designed to support sustainable procurement processes. This includes digital platforms, data analytics, and supply chain management tools that enable organizations to assess suppliers’ sustainability performance, track lifecycle impacts, and ensure compliance with environmental standards. A well-designed technical architecture facilitates transparency, accountability, and informed decision-making by providing real-time data and automating sustainability criteria integration. Together, sustainable procurement and technical architecture create an interconnected approach where technology enhances the ability to procure responsibly. This synergy helps organizations reduce carbon footprints, promote circular economy practices, and foster innovation in green products and services, ultimately contributing to a more sustainable and resilient supply chain ecosystem.
