The Nexus between Green Finance, Climate Finance, and Sustainable Development in Nigeria: An ARDL Bounds Testing Approach
Using an ARDL bounds testing approach on Nigerian data from 1990 to 2023, this study confirms that while green and climate finance significantly drive long-term sustainable development, their current scale and structural limitations, alongside transitional costs and institutional inefficiencies, necessitate strengthened policy frameworks and expanded private-sector participation to fully achieve Nigeria's climate and development goals.

In the global effort to build a future that does not destroy the planet, money plays a role as critical as any technology or law. This field, often called green finance, involves directing funds toward projects that help the environment, such as renewable energy, clean water systems, or reforestation. A closely related concept is climate finance, which specifically targets money used to either reduce the emissions that cause global warming or to help communities adapt to the changing weather they are already facing. For a country like Nigeria, which faces severe environmental challenges ranging from desertification to flooding, the question is not just whether these funds exist, but whether they are actually working to improve the nation's overall well-being. Sustainable development is the goal of balancing economic growth with environmental protection and social fairness, ensuring that people can thrive without depleting the resources their children will need.
A recent study by Kingsley Success Ikani at the University of Economics in Katowice investigates exactly how these financial flows are performing in Nigeria. The research looks at data spanning from 1990 to 2023, a period that covers decades of economic change and environmental shifts. The author wanted to understand the relationship between the money flowing into green and climate projects and the country's progress toward sustainable development. To do this, the study used a statistical method that can separate immediate, short-term effects from long-term trends. This approach allowed the researcher to see not only if the money helps, but also how long it takes for those benefits to appear and whether the relationship between funding and progress is stable over time.
The findings reveal a story of promise mixed with growing pains. In the long run, both green finance and climate finance have a clear, positive impact on Nigeria's sustainable development. When the country increases its investment in green bonds, loans for renewable energy, or funds for climate adaptation, the overall health of its economy, environment, and society improves. The study found that climate finance, in particular, has a strong effect, suggesting that money directed specifically at fighting climate change is a powerful engine for sustainable growth. However, the short-term picture is more complicated. While green finance provides an immediate boost, climate finance often shows a negative effect in the short term. This counterintuitive result does not mean the money is wasted; rather, it suggests that the initial phase of these projects involves high costs and logistical hurdles. Building new infrastructure, setting up new systems, and training people take time and resources before the benefits begin to flow.
The research also examined other factors that influence Nigeria's development. It found that high inflation, or the rapid rise in prices, undermines sustainable progress, making it harder for the country to grow in a stable way. Foreign investment, often seen as a sign of economic health, showed a negative relationship with sustainability in the short term, possibly because much of this money still flows into traditional, non-green sectors like oil and gas. Conversely, when domestic banks lend more money to local businesses, it supports sustainable growth. The study confirms that the relationship between finance and development is stable and predictable over time, meaning that once the initial hurdles are cleared, the system works as intended.
Despite these positive long-term trends, the study highlights a significant gap between what Nigeria needs and what it is getting. The country currently attracts about 2.5 billion US dollars in climate-related finance annually, a figure that has grown by 32 percent in recent years. However, this amount covers less than 10 percent of the estimated 27.2 billion US dollars the country needs each year to meet its climate goals and sustainable development targets. The structure of this funding is also unbalanced, with about 70 percent coming from public sources and international donors, while private companies contribute only about 30 percent. Most of the money arrives as loans, which adds to the country's debt, rather than as grants or investments that do not require repayment.
The author concludes that while green and climate finance are essential tools for Nigeria's future, the current system is not yet large or efficient enough to solve the country's environmental challenges on its own. The research points to several barriers, including unstable economic conditions, a lack of well-prepared projects ready for investment, and weak coordination between different government agencies. To move forward, the study suggests that Nigeria needs to diversify its funding sources, encouraging more private companies to invest. It also calls for better planning to ensure that projects are ready to go as soon as money becomes available, and for stronger rules to ensure transparency so that investors can trust where their money is going. The path to a sustainable Nigeria is clear, but it requires filling a massive financial gap and smoothing out the rough edges of implementation to turn potential into reality.
