Kenya's Green Finance Taxonomy Explained: What Banks, Borrowers, and Investors Need to Know

What the Kenya Green Finance Taxonomy actually is

The Kenya Green Finance Taxonomy (KGFT), issued by the Central Bank of Kenya on 4 April 2025 with technical support from the European Investment Bank, is Kenya's first national classification system for sustainable economic activities. It defines which activities qualify as environmentally sustainable, creating a common language for green finance across the Kenyan financial system.

The KGFT is not a reporting framework — it does not tell organisations what to disclose. It is a classification system that tells lenders, investors, and borrowers whether a given economic activity meets the threshold to be labelled "green." Its significance lies in the binding power it creates: once an activity is or is not taxonomy-aligned, that determination affects what banks can call a green loan, what asset managers can include in a green fund, and what project developers can represent to ESG-focused investors.

The three-part test for taxonomy alignment

Every economic activity assessed under the KGFT must satisfy three cumulative criteria:

Significant Contribution (SC) — The activity must make a substantial positive contribution to at least one of the taxonomy's environmental objectives: climate change mitigation, climate change adaptation, sustainable use and protection of water and marine resources, transition to a circular economy, pollution prevention and control, or protection and restoration of biodiversity and ecosystems.

Do No Significant Harm (DNSH) — The activity must not significantly harm any of the other environmental objectives. An activity that substantially contributes to climate change mitigation but causes significant biodiversity damage does not qualify as taxonomy-aligned.

Minimum Social Safeguards (MSS) — The activity must comply with minimum standards for social and labour rights, including adherence to the ILO core conventions, respect for human rights, and basic governance requirements. This criterion ensures that the green label is not available to activities that achieve environmental goals at the expense of workers or communities.

All three criteria must be met simultaneously. Meeting two out of three is not sufficient for taxonomy alignment.

What the KGFT currently covers

The April 2025 taxonomy covers ten categories of economic activities, focused initially on climate change mitigation and adaptation:

• Renewable energy: Solar, wind, geothermal, small hydro, and other clean power generation
• Energy efficiency: Building retrofits, industrial process efficiency, efficient appliances and equipment
• Sustainable transport: Electric vehicles, public transport infrastructure, rail freight
• Sustainable land use and agriculture: Climate-smart agriculture, sustainable forestry, agroforestry
• Water and wastewater management: Water efficiency, wastewater treatment, flood protection
• Green buildings: New construction and renovation meeting defined energy and environmental standards
• Sustainable infrastructure: Climate-resilient infrastructure design and construction
• Clean technology and manufacturing: Low-carbon industrial processes and technologies
• Natural resources and biodiversity: Conservation finance, ecosystem restoration, blue economy activities
• Climate risk management: Financial products and services that support adaptation to climate impacts

Future editions of the taxonomy will expand to cover additional environmental objectives and are expected to broaden the scope to asset managers, pension funds, and insurance companies.

Who is affected and when

Currently (voluntary phase — April 2025 to approximately October 2026): All commercial banks, mortgage finance companies, and other financial institutions are encouraged to begin voluntarily applying the taxonomy to their green lending portfolios. This phase is designed to allow institutions to build the systems, data, and expertise needed for mandatory compliance.

Mandatory phase (approximately October 2026 onwards): Commercial banks and mortgage finance companies regulated by the CBK will be required to implement the KGFT. The specific mandatory requirements — including disclosure formats, verification requirements, and reporting timelines — are expected to be communicated by CBK ahead of the mandatory date.

Anticipated future expansion: CBK has signalled that subsequent iterations of the taxonomy will extend mandatory application to asset managers, pension funds, and insurance companies, bringing Kenya's classification framework progressively in line with international standards.

What taxonomy alignment requires in practice

Meeting the KGFT's three-part test requires more than a general statement that a project or loan is environmentally beneficial. Institutions that want to designate lending as taxonomy-aligned will need to:

Define eligible activities within their portfolios using the taxonomy's activity-level criteria and technical screening thresholds (specific metrics that define "significant contribution" for each activity category).

Conduct DNSH assessments against all six environmental objectives for each activity designated as aligned. This requires data on the activity's environmental footprint beyond just its primary environmental benefit.

Verify MSS compliance by confirming that borrowers meet minimum social and governance standards — which for many institutions will require integrating social due diligence into the green lending process.

Report and disclose the proportion of their portfolio that is taxonomy-aligned, using standardised metrics. The CBK is expected to specify disclosure formats aligned with the mandatory phase requirements.

Why 18 months moves faster than organisations expect

Institutions that wait for mandatory requirements to be gazetted before beginning taxonomy alignment work face a compressed timeline. The experience of European financial institutions with the EU Taxonomy — the framework that Kenya's KGFT is modelled on — consistently shows that:

• Data collection for DNSH assessments requires granular borrower-level environmental data that most institutions do not currently collect through their standard credit processes
• Portfolio mapping to identify which existing lending is potentially taxonomy-eligible takes longer than anticipated when done rigorously
• Staff training across credit, risk, and compliance functions is essential and cannot be completed at the last minute
• Systems integration — embedding taxonomy criteria into credit origination and monitoring processes — involves IT development that rarely happens quickly

Banks and other financial institutions that begin voluntary taxonomy alignment now are building the operational muscle they will need under mandatory requirements. Those that start only when required face doing this work at pace, under regulatory scrutiny.

3 critical questions for banks, investors, and project developers

1. If you are a bank or mortgage finance company, have you mapped your existing lending portfolio against the KGFT activity categories to identify what proportion of your current book is potentially taxonomy-eligible?

2. Do your credit origination and monitoring processes currently collect the environmental and social data needed to assess DNSH compliance and MSS at the borrower level?

3. If you are a project developer seeking green finance from Kenyan banks or international DFIs, is your project designed and documented in a way that demonstrates taxonomy alignment — including both the positive environmental contribution and the DNSH assessment?
