Unlocking Africa's Green Bond Potential: Bridging the Climate Finance GapAfrica's share of the global USD 2.2 trillion green bond market is less than 1%. To increase its green bonds market share, Africa must mobilize the combined capacity of corporations, municipalities, banks, and sovereign governments. Although the growth of the green bond market in Africa trails the rest of the world, the continent has enormous potential to issue more green bonds. By 2023, over 20 green bonds had been issued by Tanzania, Rwanda, Gabon, Seychelles, Nigeria, South Africa, Kenya, Morocco, Mozambique, Namibia, Mauritius, and Zambia.## Unleashing Africa's Green Bond Boom### Tapping into Sustainable Finance OpportunitiesThe global surface temperature is expected to exceed 1.5 degrees Celsius above pre-industrial levels, and Africa's climate bill is expected to further escalate. Estimates indicate that Africa needs USD 2.8 trillion by 2030 to implement its Nationally Determined Contributions (NDCs). To meet this trillion-dollar climate bill, African countries must diversify their climate finance sources to include more non-traditional avenues, such as sustainable finance markets.### Defining Green Bonds: A Powerful Tool for Climate ActionGreen bonds are fixed-income instruments that raise capital for projects delivering positive environmental or climate benefits. Issuers of green bonds must include a 'use of proceeds' clause to ensure that the funds are allocated to environmentally beneficial projects. Green bonds are issued and regulated based on national frameworks and voluntary international guidelines that align with global climate goals, such as the Paris Agreement and the UN's Sustainable Development Goals (SDGs).### The Global Green Bond Market: Exponential Growth and DiversificationThe global green bond market has experienced exponential growth, surging from under USD 50 billion in 2015 to approximately USD 2.8 trillion in 2023, with USD 575 billion issued in 2023 alone. This growth has been driven largely by the increasing demand for climate-positive investments following the Paris Climate Accord, as investors and issuers alike prioritize sustainability. The market has seen a diversification of issuers, including corporations, municipalities, banks, and sovereign governments.### Africa's Green Bond Landscape: Untapped PotentialDespite the global surge of green bond issuances, sub-Saharan private and public sectors have not fully benefited from this source of climate finance. Africa represents only USD 5.1 billion of the total USD 2.2 trillion green bond market, compared to USD 47.2 billion for Asia Pacific (minus China) and USD 48 billion for Latin America. However, green bond issuances in Africa grew by 125% in 2023, reaching USD 1.4 billion, up from USD 600 million in 2022.### Pioneering Green Bond Issuances in AfricaThe African Development Bank (AfDB) has become a pioneer for sustainable financing in Africa, issuing its first green bond of USD 500 million in 2013. Several more issuances have followed, including the latest 2023 USD 50 million 15-year Kangaroo Green Bond. South Africa led the African market's early development with its sustainable finance taxonomy and green listing rules introduced in 2017, enabling Cape Town and Johannesburg to issue municipal green bonds.Nigeria dominates the public issuance of green bonds, accounting for approximately 99% of green bonds listed on the Nigerian Stock Exchange. African countries such as Morocco, Namibia, and Kenya have also issued corporate green bonds with government guidance. In 2023, Africa saw further, important debut issuances, including the Rwanda Development Bank's sustainability-linked bond (SLB), Gabon's blue bond through a 'debt-for-nature swap', and Zambia's first corporate-led green bond from Copperbelt Energy Corporation.### Lessons from Zambia's Green Bond JourneyZambia's first-ever green bond, issued by Copperbelt Energy Corporation in 2023, was oversubscribed by 178%. Before this issuance, Zambia faced several challenges, including a lack of awareness, guidelines, customized incentives, green bond ratings, and a pipeline of suitable projects. To address these challenges, a working group led by the UNDP Biodiversity Finance Initiative, in collaboration with various government ministries and WWF Zambia, developed green bond guidelines and hosted workshops to raise awareness amongst potential issuers.### Overcoming Barriers to Green Bond Growth in AfricaDespite its growth potential, the African green bond market faces several challenges, including a lack of developed local markets, inadequate green bond regulation, limited environmental, social, and governance (ESG) capacity, underdeveloped capital markets and project pipelines, high transaction costs, and a lack of independent verifiers. Lessons from countries like Nigeria, South Africa, Kenya, and Zambia highlight the potential for overcoming these barriers through raising awareness, offering tax incentives, establishing clear green bond standards, investing in internal ESG capacity, identifying bankable projects, and reducing issuance costs.### Unlocking Africa's Green Bond Potential at COP29Africa's under-utilized green bonds market may be the key to help it bridge its trillion-dollar climate finance gap. By scaling up the green bond market, critical climate projects can be funded to unlock Africa's potential for sustainable development and resilience. Governments, financial institutions, municipalities, investors, and corporations at the upcoming COP29 must commit to accelerating the creation of enabling environments, capacities, and collaborations for green bond issuance in Africa.
