Abstract
Sustainable finance is a key tool to link financial decision-making with environmental integrity, social inclusion and long term economic resilience. Its agenda is consequential for Nigeria: the country’s challenge is to increase energy access, infrastructure, employment, productive investment, accommodate vulnerability to climate change, curtail pollution, biodiversity loss and the risks of a gradual global shift from high-carbon activity. This conceptual review analyzes sustainable finance in Nigeria using Nigerian policy and market documents, and selected international research and standards. It defines the concept and scope of sustainable finance; outlines key instruments and institutional enablers of sustainable finance; evaluates the environmental, economic, social and financial-stability benefits of sustainable finance; and explores potential barriers to ensuring capital flows into sustainable finance that impact its ability to generate tangible development results. The review views Nigeria’s sovereign green-bond issuance and its Sustainable Bond Framework as a measure of institutional development but not as an indicator of the current state of the green-bond marketplace or a guarantee of a sustainable financed outcome. The analysis pinpoints recurring difficulties related to long-term capital, the availability of currency and macroeconomic risk, hurdles in project preparation, the lack of reliable sustainability information, skills deficits, scattered coordination and poor monitoring as well as the potential of “green washing. Suggests a context specific approach based on five elements: policy credibility, project pipelines that can be invested, financial intermediation, disclosure and verification, inclusion, and outcome measurement. The main thrust is not only the amount of labelled instruments, but also the additionality, integrity, affordability and distributional equity of sustainable finance and iAl-Amin (2025) independently demonstrated environmental and social outcomes in Nigeria. The article ends with policy priorities and a research agenda to further build a more credible, inclusive and developmentally robust sustainable finance ecosystem.
