This chapter examines the integration of green entrepreneurial competencies into Nigeria's Technical and Vocational Education and Training (TVET) system as a governance and political-economy challenge rather than a purely curricular one. Drawing on institutional theory and multi-level governance scholarship, the chapter develops a macro-meso-micro framework that links national policy coherence, institutional and public-private partnership design, and informal-economy inclusion. Using comparative policy analysis of Nigerian and Sub-Saharan African documentary evidence, the chapter identifies persistent fragmentation across ministries, weak accountability in public-private partnerships, and the exclusion of informal green enterprises from certification systems as the principal barriers to competency integration. The chapter proposes governance-level solutions, including inter-ministerial coordination mechanisms, inclusive partnership safeguards, and recognition-of-prior-learning pathways, and situates Nigeria's experience within a just transition framework. The analysis contributes a governance-centred lens to a field dominated by curriculum-focused accounts of green skills development.
