Purpose: This literature-based study assessed green procurement practices as a strategic tool for protecting the environment in favour of the performance of manufacturing firms.
 Design/Methodology/Approach: A systematic qualitative scrutiny aided by nomothetic content analysis from the published papers centred on green procurement as a global strategic approach to protecting the environment was employed.
 Findings: Green procurement practices are documented as useful for the performance of firms. Moreover, little has been pronounced on relevant practices in Tanzania. Manufacturing firms are charged for environmental compliance and hence call for a related conceptual study.
 Research Limitation/Implication: The study limited itself to the literature alone out of no cause-effect relationship testing of green procurement practices against performance hence calling for the quantitative study guided by hypothesis testing. 
 Practical Implications: The practical implications of the green procurement nexus on the performance of manufacturing firms are significant and can influence various aspects of a company's operations, sustainability efforts, and overall success.
 Social Implications: The study contributes to the Environmental Social Governance (ESG) agenda by highlighting the green procurement practices to be taken on board for the social wellbeing of the delivery of materials to manufacturing firms in consistency with the governance mechanisms.
 Originality/Value: Suggestion: The novelty of the study on the green procurement nexus and manufacturing firm performance lies in its empirical, multidimensional, and forward-looking approach to understanding how sustainable procurement practices can impact various facets of a manufacturing firm's operations and long-term sustainability. It contributes to the growing body of knowledge on the intersection of sustainability and business performance.
