PurposeThis study presents the state of green bond markets in Africa and green bond funds by some countries in the continent.Design/methodology/approachThe authors adopt a case study approach on four different kinds of countries, namely oil-rich economy, green bond innovator, renewable energy user and carbon vulnerability.FindingsThe authors found that Africa's green bond is still at the early stages. However, countries are using innovative ways that are adaptable to their current economic conditions and investment attractiveness in issuing green bonds. While some countries focus on central and local government bonds, others use corporate bonds, few combine government and corporate green bonds. Interestingly, the first green bond globally certified by the Climate Bonds Standard was issued by an Africa country in Africa. In some selected countries such as Nigeria, South Africa, Morocco, Namibia and Kenya, green bond markets have seen massive growth and have contributed to numerous infrastructural energy efficiency projects. To expand this market further in these countries, the authors recommend fostering a public–private partnership backed by policies and political will.Originality/valueThis study provides an original contribution to the green bond and its likelihood of driving energy efficiency in a continent that has attracted little to no attention in the literature.
