The green bond market has developed rapidly in advanced economies, but much less so in emerging and developing countries. There is no good reason for this. Emerging and developing countries also have great green projects and enormous investment needs.
Africa’s green bond market may be small, but the challenge it can help address is enormous. As climate impacts intensify, African countries must find ways to finance mitigation and adaptation without placing unsustainable pressure on public finances. Doing so will require not only capital, but also the financial infrastructure needed to attract it.
Green bonds are not a silver bullet, but they are one of the most practical tools available. They allow governments, cities, banks and companies to raise capital for clearly defined climate and environmental projects. Investors receive a return, while the proceeds are earmarked for renewable energy, clean transport, climate-resilient infrastructure, green buildings, water systems or sustainable land use.
Africa’s green bond market is still young, accounting for less than one percent of the global market. But momentum is building.
Nigeria was a frontrunner, issuing its first sovereign green bond in 2017. Egypt, Kenya, Morocco, Namibia and South Africa have also helped demonstrate growing issuer and investor appetite.
Recent analysis by FSD Africa found that to date, the continent has raised around $9.6 billion through approximately 76 green bond issuances from around 40 issuing entities. This shows that green bonds in Africa are no longer merely an idea, but an emerging financing channel.
The challenge now is to turn these early successes into a mature market.
The continent requires substantial annual investment to meet the goals set out in countries’ Paris Agreement commitments. Domestic budgets are constrained, international capital can be expensive, and many countries face debt sustainability pressures.
Green bonds can help diversify the sources of climate finance by attracting investors looking for credible, long-term sustainable investment opportunities.
The real value of green bonds goes beyond the money raised in a single issuance. They can help build stronger domestic capital markets. They require issuers to identify eligible green projects, establish transparent frameworks, report on the use of proceeds and measure environmental impact.
These practices strengthen market discipline, improve investor confidence and support the development of national green taxonomies and sustainable finance frameworks.
Many potential African issuers face barriers that are not only financial. They may need greater technical capacity to develop internationally recognised frameworks or obtain external verification. Currency risk, limited project pipelines, high borrowing costs and fragmented regulatory environments can also discourage issuers and investors.
Addressing these constraints requires more than individual transactions. It requires institutions that can help develop project pipelines, support first-time issuers and reduce risks for investors. This is the rationale behind the Global Green Bond Initiative.
Backed by a European Union budgetary guarantee under the Global Gateway strategy, the initiative brings together a consortium of European development finance institutions, led by the European Investment Bank. The initiative is also being supported by the Green Climate Fund, which is the world’s largest dedicated multilateral climate fund.
Just as importantly, financing will be accompanied by strong technical assistance, helping countries and issuers put in place the frameworks and capacity needed to issue credible green bonds and develop a pipeline of investable projects. This will demonstrate how multilateral co-operation can scale up climate action where it’s needed most.
This combination of capital, risk-sharing and technical expertise can help turn an emerging green bond market into a powerful source of finance for sustainable investment.
For Africa, this is about more than attracting European capital. It is about building stronger domestic markets so that more African climate investment can be financed through African institutions, African issuers and African savings.
This also requires broader support for the greening of Africa’s financial systems. The Greening Financial Systems technical assistance programme works with central banks and commercial banks to help them identify, assess and manage climate-related risks, integrate them into business strategies and expand green lending.
Financed by the German and Luxembourg governments and closely coordinated with the NDC Partnership, it can also support the development of national green taxonomies to guide sustainable investment. Such work is ongoing in Kenya, Ethiopia and Rwanda, with discussions to expand to other African markets. Without this enabling environment, green bond markets cannot scale.
Africa is well placed to lead in areas that are increasingly important globally, including nature-related finance, biodiversity, sustainable agriculture and climate adaptation. The continent’s natural capital, renewable energy potential and rapidly growing infrastructure needs create a strong basis for green investment.
Success, however, will not be measured by a handful of headline-grabbing issuances. It will depend on African governments, banks and businesses returning to the market again and again, supported by deeper investor pools, stronger regulation and a growing pipeline of viable projects.
