The Kenya Green Finance Taxonomy Is Live. The 18-Month Clock Is the Part Banks Keep Missing

When the Central Bank of Kenya issued the Kenya Green Finance Taxonomy (KGFT) and the Climate Risk Disclosure Framework (CRDF) on 4 April 2025, a lot of banks read one word — "voluntary" — and moved on. That is the reading that gets institutions into trouble.

The taxonomy applies to commercial banks and mortgage finance companies on a voluntary basis for 18 months from the date of issuance. Read that again. Voluntary and time-boxed are not the same as optional and open-ended. The 18-month window is the runway CBK has given the sector to build the capability before expectations harden. Institutions that treat it as breathing room rather than build time will arrive at the end of the runway without a plane.

What the two frameworks actually do

They do different jobs, and it helps to keep them separate:

The Kenya Green Finance Taxonomy (KGFT) is the classification system. It defines what economic activities can legitimately be called "green." If you want to tag a loan as green, issue a green bond, or report the green share of your portfolio, the taxonomy is the reference that stops it from being marketing.
The Climate Risk Disclosure Framework (CRDF) is the reporting framework. It sets out how banks should collate and disclose climate-related information so that it is relevant, useful, consistent, and comparable — across governance, strategy, risk management, and metrics.

Crucially, the CRDF is aligned with IFRS S2, which the Institute of Certified Public Accountants of Kenya designated as the official standard for climate risk reporting back in November 2024. It also references the Basel Committee on Banking Supervision. In other words, this is not a Kenya-only invention that will diverge from the rest of the world — it is the global disclosure architecture, arriving locally.

The dates that actually bite

Disclosure without assurance is a claim. Assurance is what turns it into something a regulator or investor can rely on, and the assurance timeline is where the real deadlines sit:

From 1 January 2028, ICPAK-licensed assurance providers will require evidence to give limited assurance over climate-related disclosures.
From 1 January 2030, that escalates to full reasonable assurance, including Scope 3 — the financed emissions in your lending book.

Scope 3 is the hard one. For a bank, the vast majority of climate-relevant emissions are not in your branches or your fleet; they are in what you finance. Getting to reasonable assurance over financed emissions by 2030 is not a reporting exercise you start in 2029. It is a data, systems, and methodology project that takes years.

What "using the window well" looks like

The banks getting ahead of this are not writing their 2030 disclosure today. They are doing the unglamorous groundwork that makes the disclosure possible later:

Deciding who owns climate data internally, and building the responsibility matrix to prove it.
Mapping their portfolio against the KGFT so green classification is defensible, not aspirational.
Standing up the beginnings of a financed-emissions (PCAF-aligned) measurement capability, because Scope 3 will not assemble itself.
Running an honest gap analysis against the CRDF and IFRS S2 so they know what is missing before an assurer tells them.

None of that requires waiting for the taxonomy to become mandatory. All of it takes longer than institutions expect.

If you want a clear, structured picture of where your institution stands against the CRDF today — and what to do first — that is what the Climate Risk Readiness Diagnostic produces.
