We build climate
unicorns in Africa

Our Thesis

Climate action is reshaping the global economy

Consumers are shifting towards climate-friendly products.

Governments, aiming for net-zero, are shifting policy and committing billions of dollars to climate action.

New technologies, processes, and energy sources are being developed, revolutionizing markets and redefining country resource endowments.

Carbon markets are flourishing, fostering new business models and sectors, while facilitating large-scale deployment of low-carbon solutions.


Africa is inherently well-positioned to tap into new climate-related business opportunities

Intrinsic Competitiveness

Africa has abundant affordable land, untapped renewable energy potential, and a growing, increasingly skilled workforce, all of which are key cost drivers of climate action. Africa’s soils are also weathered and often acidic, offering significant opportunities for regenerative agriculture. 

Readily Available Opportunities To Tap Into Carbon Revenues

By prioritizing low-carbon business models, and incorporating carbon revenue, existing African businesses can drive affordability, amplify sustainable practices, and empower local communities, addressing climate change and providing global climate solutions.

Potential For And Urgency Around Co-Benefits

Socio-economic challenges drive significant potential for co- benefits in Africa. Many actors with the capability, experience, and (community) connections to realise co-benefits have the opportunity to transform their business model to reduce dependency on philanthropic funding.

ACV identifies opportunities to develop climate-smart businesses on the African continent following three key models

Technology Transfer to Africa

Identify leading global businesses with exciting carbon technologies, then bring them to Africa. Leverage our deep knowledge of Africa to develop appropriate entry strategies for applicable technologies, and build effective teams to launch businesses across the continent.

Scaling Out Successes Across Africa

Identify home-grown African climate tech businesses that are gaining traction in the market in which they were developed and help them rapidly accelerate into new markets, leveraging local know-how and relationships, and augmenting typically overstretched management teams.

Adding carbon revenues to business model

Identify businesses on the continent with under exploited carbon potential (e.g., electro moto manufacturers who are not monetizing their carbon). Provide skills and capabilties to add carbon revenues to these businesses, increasing profitabilty, adding value, and speeding growth.

How We Work

Sometimes we develop a concept ourselves and attract the right founder, sometimes we find a founder with a great idea.  In all cases, we roll up our sleeves, iterate and improve on concepts, continuously inject capital as key milestones are met, and leverage our networks and expertise to give the business the best chance of success.

Our lives depend on curbing climate change, but so many priorities seem to be in competition. What’s the most urgent thing humanity can do right now? Social entrepreneur James Irungu Mwangi tells us why Africa could be the ideal home for scaling the latest and most ambitious climate technologies — including in places like Kenya’s Hell’s Gate National Park, which could become part of what he calls the “Great Carbon Valley.”

KOKO Networks Rwanda

In early 2021, KOKO Group and Africa Climate Ventures set up a Joint Venture to scale KOKO Networks outside of Kenya for the first time.  KOKO Networks (www.kokonetworks.com) is an emerging markets climate technology company that serves sustainable bioethanol cooking fuel to over 900,000 Kenyan families every day.

At the start of 2022, KOKO Networks Rwanda signed an agreement with Government of Rwanda that commits us to reaching 1 million families by the end of 2026 and providing KOKO’s completely clean cooking solution at a price point below that of charcoal. The agreement freezes all taxes on KOKO’s stoves, fuel, and equipment in Rwanda.

At the moment, we are actively building the company and its networks in Rwanda, with the target to go live in Kigali in the second half of 2023.

Circular economy

A significant portion of Africa’s industrial and household waste remains underutilized. The emergence of climate-conscious usage possibilities, which are becoming increasingly commercially viable, offers tremendous potential for growth.

Climate smart agriculture

Agriculture in Africa, traditionally characterized by low productivity, is evolving. A variety of soil enhancements and practices, powered by carbon, are emerging. These innovative methods promise to boost agricultural yield and foster resilience.

Climate positive built environment

Africa’s growing, urbanizing population will need buildings. Green buildings – through smart design and low-carbon materials – are critical to limit Africa’s climate footprint and present an enormous market opportunity.


Increasingly models are emerging to bring new electric vehicles to Africa markets. As these models mature and additional EV infrastructure is put in place, the market will present a significant growth opportunity.

Carbon removals and green industry

The abundant land and renewable energy resources in Africa make it a prime location for the development and implementation of emerging carbon removal technologies and green industries.
