This review explores the current state and future potential of green building technologies (GBTs) in Tanzania. Using a desk-based literature review and thematic synthesis, the study analyzes peer-reviewed articles, policy documents, and case studies to assess the applica- tion of material solutions, energy efficiency strategies, and water management practices in diverse country settings. The findings indicate that the most significant obstacles to the widespread adoption of green building technologies in Tanzania are the absence of mandatory regulatory frameworks, insufficient technical capacity, limited public awareness coupled with financial constraints, and weak institutional coordination. Technically, the most feasible pathway involves integrating locally sourced low-carbon materials and the adoption of climate responsive passive design strategies that are tailored to the country’s diverse climatic zones and socio-economic conditions. In order to address the identified setbacks, this paper proposes several strategic interventions including the formulation of context-specific green building standards, enhanced support mechanisms for local material innovation within the construction sector, targeted capacity-building programs, and the establishment of inclusive green financing schemes to support small-scale developers
