Four out of every 10 dollars invested in African start ups now goes to climate tech

Africa’s venture capital market returned to growth in 2025, with climate-linked startups accounting for a larger share of capital deployed across the continent.

Latest data from Africa The Big Deal, a research initiative that tracks start‑up investment across the continent, shows the venture capital market returned to growth in 2025, but one theme stood out more clearly than the headline rebound.

Climate related businesses, spanning energy, agriculture and transport, are steadily increasing their claim on investor capital.

Startups with a climate focus raised about $1.2 billion in 2025, representing roughly 38 per cent of all venture funding on the continent this year. The share is almost identical to 2023 and up from 34 per cent in 2024, when overall funding had fallen sharply.

Climate tech companies accounted for 29 per cent of all startups that raised at least $100,000 in 2025. That is up from 28 per cent in 2024 and 26 per cent in 2023. Just a few years ago, in 2021 and 2022, the figure was closer to one in five.

In other words, climate is no longer a niche theme attracting a handful of large solar deals but  spreading across the ecosystem.

Part of that growth reflects the structure of Africa’s energy market. The energy sector rebounded strongly in 2025, raising $857 million, almost double its 2024 level. Much of that came from large debt facilities secured by off grid solar providers and clean cooking companies. A small group of companies accounted for the bulk of that capital.

Debt played a central role with more than two thirds of energy funding this year came in the form of loans and structured facilities rather than equity. That model suits businesses that sell solar home systems or clean appliances on instalment plans, where predictable cash flows can support borrowing.

Yet climate capital is not confined to energy. Agriculture and food startups, many focused on climate resilience, supply chains and sustainable inputs, raised $122 million across 62 companies.

Logistics and transport businesses, some working on electric mobility and efficiency, secured $309 million. Even within fintech, climate related lending and carbon linked services are beginning to appear.

Unlike sectors such as healthcare, where a single large round can dominate annual figures, climate tech shows both scale and breadth. Nearly 150 climate focused companies raised funding in 2025. That makes it one of the few themes combining large ticket transactions with a growing number of smaller raises.

The broader venture market tells a more uneven story. Total funding across sectors recovered to $3.2 million in 2025 from $2.2 billion in 2024, but much of that rebound was driven by a handful of very large deals. The number of funded companies remained broadly stable, suggesting that capital is still selective.

Against that backdrop, climate’s rising share looks less cyclical and more structural.

Investors appear to view climate linked businesses not simply as impact plays, but as responses to real constraints: unreliable grids, rising food insecurity and pressure to decarbonise transport. For international lenders and development finance institutions in particular, climate offers a clear mandate and measurable outcomes.

The result is a gradual reshaping of Africa’s venture landscape. Climate tech is not displacing fintech as the largest sector by value but becoming embedded across industries, increasing its share of both dollars and deals.
