Who’s Issuing Them and Why They Matter — Green Bonds in Kenya
Green bonds, debt instruments whose proceeds are earmarked for projects with clear environmental benefits, have moved from novelty to a practical tool for financing climate solutions in Kenya. The market here is still young and shallow compared with mature markets, but the last six years have shown that both private companies and the state can use green bonds to tap new pools of capital for renewable energy, low-carbon buildings, clean cookstoves and other climate-positive projects.
Since Acorn’s debut, green financing in Kenya has taken several different shapes. There have been private and quasi-private green notes and climate finance deals aimed at specific sectors, from clean cookstoves to energy efficiency, while development partners and market-building programmes have worked to deepen local capacity for issuing and underwriting green debt.
The Kenya Green Bond Programme, endorsed by the National Treasury, Central Bank and the Capital Markets Authority, has been a key piece in boosting technical capacity and market awareness.
Most recently, the state itself has signalled that it will be an active player. A sovereign-scale green or sustainability-linked bond was reported in mid-2025, with broad international demand, pointing to growing appetite among global investors for Kenyan climate finance instruments. That move, if sustained, would be a major market-deepening moment: sovereign issuances create benchmarks, build liquidity, and encourage private issuers to follow with credible green paper.
Which organisations are issuing green or climate-linked debt in Kenya today? The pipeline includes three broad groups: pioneering corporates that have already issued green notes or are actively exploring green bonds; corporations using sustainability-linked loans and other tied instruments to fund transition projects; and government or quasi-sovereign issuances aimed at larger infrastructure and energy programmes.
On the corporate side, Acorn remains the textbook example: its 2019 issuance (roughly USD 40 million) financed green student accommodation and was Climate Bonds Initiative certified, showing that Kenyan real estate developers can meet international criteria for green use of proceeds.
Telecoms giant Safaricom offers a case study for the “transition finance” route. Rather than a classic green bond, Safaricom has raised large sustainability-linked loans from local banks to finance shifts such as replacing diesel with renewables at transmission sites. The company has publicly signalled it is open to green bond issuance as it diversifies funding sources for its sustainability agenda, and its multi-billion-shilling sustainability-linked facilities show commercial lenders’ appetite for linked instruments.
Other private and private-sector players have experimented with green notes and climate financing for targeted projects, for example, off-grid energy, cookstove distribution and clean building projects, often with backing or technical assistance from development finance institutions. Those transactions tend to be smaller, project-specific and sometimes marketed to international niche investors looking for impact.
Why green bonds matter for Kenya now is straightforward. First, they can unlock large pools of capital at competitive pricing to fund renewable energy, climate-resilient infrastructure, and low-emission housing, all of which Kenya needs to meet development and climate goals. Second, certified green issuances (or strong sustainability-linked frameworks) signal credibility to international investors and can help attract foreign capital on better terms than vanilla debt. Third, by creating a market for green debt, Kenya can build domestic institutional capacity, banks, asset managers, and the NSE itself, to assess, price and trade climate risk and green returns.
Yet several constraints limit faster growth. The domestic bond market remains relatively shallow, which makes pricing and liquidity fragile for new instrument types. Issuers face high upfront costs for verification, structuring and external reviews required to meet international green standards, and many potential corporate issuers, particularly SMEs, lack the internal systems to produce the environmental data that underpins credible green reporting. Market education, standardised taxonomies, and scalable project pipelines are still works in progress. The Capital Markets Authority and industry bodies have issued policy guidance and issuer toolkits to help, but capacity gaps remain.
There are also evolving choices about instrument type. Traditional “use-of-proceeds” green bonds allocate funds only to eligible green projects and require ongoing reporting and verification, while “sustainability-linked” loans or bonds tie pricing to issuer-level ESG or climate performance targets. The latter can be attractive for corporates seeking flexibility, but they require robust target setting and credible metrics to avoid accusations of greenwashing. Kenya’s market is seeing both models: sustainability-linked bank facilities at scale in telecoms and other sectors, and use-of-proceeds issuances for specific green projects.
For Kenya to scale green bonds, the next steps are clear. Governments and development partners should continue to build standardised taxonomies and de-risking facilities that reduce transaction costs for early issuers. Domestic institutional investors, pension funds, insurers and banks need incentives and clearer guidance to allocate a growing share of their portfolios to green paper. On the issuer side, corporates must invest in ESG systems and pipeline projects that can absorb large ticket financing. Programs that bundle smaller projects into investible securitised packages would also help channel capital to distributed climate solutions such as off-grid solar, efficient cookstoves and climate-smart agriculture.
The practical payoff is already visible. Acorn’s early success proved that certification and investor acceptance are possible. Safaricom’s sustainability-linked financing demonstrates banks’ willingness to back credible transition plans. And a sovereign-level green or sustainability-linked move would establish pricing and demand benchmarks that could turbocharge private market development. In short, green bonds are not only financing instruments; they are market-building tools that can help Kenya translate climate commitments into investible projects and tangible outcomes.
If investors, regulators and issuers coordinate to lower costs, standardise verification and expand project pipelines, green bonds could become an increasingly important channel for Kenya’s climate finance. The market remains young, but the policy foundations and early examples are in place; now the challenge is scaling from pilot issuances to a deep, liquid green capital market that routinely funds the country’s just transition.
