Across Africa, green finance instruments have shown promising growth.

On April 4, 2025, the Central Bank of Kenya (CBK) made a landmark move by launching the Kenya Green Finance Taxonomy alongside the Climate Risk Disclosure Framework.

These two policy tools are more than just bureaucratic milestones — they are timely instruments for redirecting Kenya's financial sector towards climate resilience and environmental accountability.

This move is especially significant as it arrives at a time when Kenyan banks are reporting substantial profits and financial stability.

With balance sheets looking healthy, the timing is perfect to begin shifting capital into future-proof investments that offer financial returns and support Kenya's sustainability ambitions.

At its core, a Green Finance Taxonomy is a classification system that defines what economic activities or assets qualify as environmentally sustainable.

It is a common language between financiers, regulators, investors, and policymakers, reducing ambiguity and minimising the risk of greenwashing.

Kenya's version of the taxonomy is tailored to national priorities but aligned with global best practices, a crucial balance that ensures local relevance and international compatibility.

By defining which projects are "green," the taxonomy enables financial institutions to confidently support sectors such as renewable energy, climate-smart agriculture, energy-efficient housing, waste management, and sustainable transport.

For Kenya, a country acutely vulnerable to the consequences of climate change, including floods, droughts, and food insecurity, this shift in capital flows is not just beneficial; it's essential.

Complementing this, the Climate Risk Disclosure Framework compels banks and financial institutions to assess and publicly report how climate risks could affect their operations and portfolios.

This level of transparency will help make climate-related financial risks visible, paving the way for more informed, resilient, and responsible lending and investment decisions. These frameworks are not just regulatory niceties.

They provide a springboard for Kenya to access green bonds, blended finance models, ESG funds, and international climate finance, all of which have largely remained underutilised due to a lack of coherence in definitions and reporting standards.

Crucially, these tools also challenge the banking sector to move from passive profit-making to proactive nation-building. Kenya's updated Nationally Determined Contributions (NDCs) require an estimated $62 billion, with only 13 percent expected from domestic sources. The rest must come from private sector partnerships and international financing

But ambition must meet implementation. Government ministries, especially the Treasury and the Ministry of Environment, must remain closely engaged to ensure policy cohesion.

By embedding sustainability into the DNA of Kenya's financial system, the CBK has made it clear: green finance isn't a buzzword, it's a blueprint for survival and prosperity.

If well implemented, Kenya could become a model for green finance leadership in Africa, showing how economic stability and climate ambition can go hand in hand.
