How banks are learning to lend to the low-carbon economy
By Ethical Business Analysis Desk – Analysis
Green credit lines are moving from the margins of sustainability rhetoric into the mainstream of African banking strategy. In Kenya and across the continent, commercial banks, global institutions and development financiers are consciously directing capital into climate‑aligned lending and reshaping credit risk models to reflect environmental and social outcomes. This shift is measurable in loan portfolio data, project pipelines and the language that leaders use to justify not only new products but a re‑imagined role for finance in the clean economy.
Green credit lines and what they do
Green credit lines are structured funds provided by development partners, DFIs and international banks to local financial institutions for on‑lending to projects that meet specific environmental criteria. These facilities often combine concessional pricing, risk sharing and technical assistance to lower barriers for borrowers and embed climate risk assessment into credit decisions. The approach aligns with findings from a major European Investment Bank survey, which shows that while close to 70% of banks in sub‑Saharan Africa see green finance as an opportunity, only a minority have fully tailored green products, underscoring both momentum and capacity constraints in the market.
Kenya’s commercial banks expand climate finance
KCB Group is among the most visible domestic leaders. According to its latest integrated report, the bank disburses KSh 53.2 billion in green loans in the year to December 2024, up 140 % from KSh 22.1 billion in 2023, with green lending now representing around 21.32 % of its total loan book. The lender also screens KSh 578.3 billion in loans for environmental and social risk, part of an expanded climate risk governance approach.
Paul Russo, KCB Group chief executive, says that the bank is “aligning our strategies to safeguard the planet and people even as we pursue profits,” indicating a conscious effort to fuse financial performance with environmental stewardship. In its sustainability report, KCB describes the expansion of green lending into sectors such as renewable energy, climate adaptation, e‑mobility and sustainable infrastructure—categories that reflect both climate and economic resilience.
Standard Chartered Kenya, a major international commercial bank operating in Nairobi, reports its own scaling of sustainable finance activities. In 2024 the bank records KES 2.99 billion in sustainable finance income, up 132 % year on year, and boosts its sustainable asset base to KES 31.3 billion. CEO Kariuki Ngari affirms that the bank is “proud of the strides we’ve made to finance sustainable progress while delivering value to communities,” a formulation that positions green lending as both commercially viable and socially inclusive.
Equity Bank has also engaged on climate finance, supported by a US$100 million subordinated loan from the International Finance Corporation (IFC) to deepen lending for renewable energy, energy efficiency and climate‑smart agricultural investments. James Mwangi, Equity Bank’s CEO, says the arrangement helps “deliver on a shared commitment to increasing financial inclusion and green finance.”
Development finance partners and blended structures
Public and multilateral finance institutions play a catalytic role in scaling green credit lines. In December 2025 the African Development Bank (AfDB) signs a US$150 million financing package with KCB Bank Kenya comprising US$100 million in subordinated debt to strengthen capital buffers and US$50 million in transaction guarantees to expand trade finance capacity for climate‑aligned projects. AfDB Director General for East Africa Alex Mubiru says the pact is “a testament to our shared commitment to advancing Africa’s green transition and ensuring that economic growth goes hand in hand with environmental stewardship
KCB Bank Kenya’s managing director, Annastacia Kimtai, frames this collaboration as “a significant milestone in our sustainability journey… to scale up green lending, catalyse private investment and support Kenya’s goal of achieving net‑zero emissions by 2050.” These partnerships signal how blended finance—mixing concessional and commercial capital—can deepen long‑term lending and make tenors and pricing consistent with climate project economics.
Expert perspectives on capacity and risk
Despite growing enthusiasm, experts caution that structural and capacity constraints could temper impact. The Kenya Bankers Association (KBA) and partners highlight that many banks lack the technical expertise and risk‑assessment tools to effectively price climate and nature‑related risks, a gap that could widen a projected USD 5 billion financing shortfall in Kenya’s green economy unless addressed through capacity building and enhanced data tools.
A WWF‑Kenya‑supported Landscape Report on sustainable finance further underscores that while banks are integrating environmental, social and governance (ESG) considerations, meaningful action requires improved governance, consistent reporting and alignment with global practice. Betty Korir, Vice‑Chair of the Kenya Bankers Association, frames this as a strategic imperative: “Sustainable business models and green financing are not mere trends—they are essential pathways for ensuring long‑term economic stability and environmental stewardship.” Raimond Molenje, acting KBA CEO, observes that industry efforts to embed sustainability have equipped more than 50,000 bank employees with decision‑making authority that benefits environment, society and economy, signalling a deeper shift in culture and competencies.
Across the continent, broader industry research corroborates this dynamic: while many banks are aware of climate risk and view green credit as an opportunity, actual green product penetration remains limited, and demand for tailored instruments is often constrained by data gaps, pricing tools and risk modelling challenges.
Sustainability metrics and inclusion outcomes
Beyond top‑line lending figures, several institutions are explicitly linking green finance to inclusion and resilience. KCB reports earmarking a meaningful portion of supplier contracts—about 7.5 % or KSh 913 million—for women‑, youth‑ and disability‑owned enterprises, illustrating how climate‑linked finance can intersect with broader equity goals. Standard Chartered’s climate reporting also highlights reduced carbon emissions and operational efficiencies, which it uses to benchmark sustainable performance internally and with clients.
Risks, regulation and the road ahead
Notwithstanding progress, risks remain. Differing definitions of what qualifies as “green” can weaken comparability and create opportunities for superficial claims if not anchored in clear taxonomies and robust disclosure. Kenya’s Green Finance Taxonomy and Climate Risk Disclosure Framework, issued by the Central Bank of Kenya, aims to standardise what constitutes sustainable finance and improve transparency, although implementation is still gaining traction.
The expert consensus suggests that sustainable finance’s future hinges on closing capacity gaps, sharpening risk pricing tools and scaling blended finance mechanisms that can absorb early risk and crowd in private capital. For policymakers, investors and bank executives, the Kenyan example underlines both the strategic value of green credit lines and the discipline required to deliver measurable impact—not only in climate terms but across economic inclusion, resilience and long‑term sustainable growth.
