Public procurement represents a significant portion of public expenditure worldwide, accounting for approximately 15-20 percent of total global GDP. This article will examine the evolving policy frameworks of sustainable public procurement (SPP) practices and the localisation of global trends across diverse jurisdictions. This research study used a qualitative methodology to assess the efficacy of current SPP frameworks, the problems associated with their implementation, and their potential to enhance the sustainability of procurement processes. The research indicates that while international norms are essential, tailored techniques must be established prior to successful implementation, contingent upon local economic, social, and environmental factors. Critical observations indicate that the adoption of SPP is prevalent in nations that have established comprehensive legal frameworks supported by efficient implementation guidelines and capacity building initiatives. However, challenges persist in the domain, including economic considerations, supplier competencies, and the assessment of sustainability outcomes. The study elucidates the methods by which policy frameworks can be developed to promote sustainable procurement practices that address local desires and constraints. Proposed recommendations include developing integrated policy solutions, augmenting institutional capacity, and creating conducive circumstances for the success of sustainable suppliers. This study provides valuable insights for policymakers, procurement professionals, and researchers to facilitate a more sustainable approach to government purchasing globally.
