Africa's Clean Air Turning Point: From Evidence to Implementation

Over four days in July, more than 500 policymakers, scientists, city leaders and financiers from across Africa gathered at the University of Pretoria for a conversation that had fundamentally shifted. Where previous forums had focused on proving that air pollution was a problem, this one was consumed with a different question: how to pay for solutions.

The 2026 Africa Clean Air Forum, held from July 13 to 16, marked a turning point in how the continent approaches its air quality crisis. The science is no longer in doubt. Cities are collecting increasingly detailed data about what they breathe. Governments are beginning to adopt cleaner fuels and rethink urban planning. What remains missing is the money and the political will to turn evidence into action at scale. The numbers underscore the gap starkly: Africa receives less than one percent of global investment dedicated to improving air quality, despite being home to some of the world's fastest-growing cities and facing mounting pollution from transport, industry, waste burning and household energy use.

The financing challenge dominated discussions throughout the week. Sean Maguire of the Clean Air Fund pointed out that while the scientific evidence linking air pollution to disease is well established, policymakers have largely failed to communicate its economic implications to the people who control budgets. Cleaner air means healthier workers, lower healthcare costs, better educational outcomes and more attractive environments for business investment. Those arguments resonate with finance ministries and investors, yet they remain largely absent from national clean air strategies. Francis V. Fragano of the World Bank Group emphasized that credible monitoring and research are the foundation for bringing finance ministries into the conversation. Without reliable evidence showing where pollution occurs, who is affected and what interventions actually work, governments struggle to build the business cases needed to secure large-scale funding. Marcia Kgatuke of the Development Bank of Southern Africa argued that blended finance—combining concessional funding, government resources and commercial capital—offers a path forward by reducing investment risks while expanding the scale of clean air programmes.

Yet the forum also revealed that Africa is not waiting for perfect financing mechanisms to emerge. Kampala has steadily expanded its air quality monitoring network to 134 low-cost sensors supported by three reference-grade monitors since 2018, demonstrating how sustained investment in locally owned systems can move cities beyond isolated pilot projects toward continuous, evidence-based management of pollution. In Kisumu, Kenya, collaboration with AirQo has strengthened the city's monitoring network, enabling authorities to identify pollution hotspots with greater precision. Across the Southern African Development Community, more than half of member states have already transitioned to low-sulphur fuels, reducing harmful vehicle emissions. In Casablanca, Morocco, researchers presented evidence showing that the closure of an open landfill corresponded with an estimated 173 avoided deaths from lung cancer and cardiovascular disease—a stark reminder that behind every policy intervention lie measurable improvements in people's lives.

The quiet revolution in how African cities measure air quality emerged as perhaps the forum's most powerful enabler. Not long ago, comprehensive air quality monitoring was beyond the reach of most municipalities because it required expensive reference-grade equipment. Today, advances in low-cost sensor technology, combined with satellite observations and increasingly sophisticated modelling, are making it possible for African cities to build far more detailed pictures of pollution than ever before. Earth observation technologies from NASA and Digital Earth Africa are helping researchers fill monitoring gaps, particularly in areas where ground-based stations remain limited. But technology alone is not enough. Delegates stressed repeatedly that monitoring only becomes valuable when it informs policy, which is why increasing attention is being given to open data platforms, locally managed monitoring networks and systems capable of translating thousands of measurements into information that city planners and policymakers can actually use.

Throughout the forum, there was an unmistakable shift toward African-led collaboration. City leaders were as interested in learning from one another as they were in hearing from international experts. Dr. Mathew Owili Ochieng, the Deputy Governor of Kisumu County, captured this sentiment when he told delegates that African cities cannot work in isolation and must share technologies and policy experience because data is the foundation of effective policy. His remarks reflected a broader recognition that the challenge now lies not in discovering new solutions but in scaling the ones Africa already has.

Yet the forum was equally clear that technology and regulation alone cannot succeed. Women, children and residents of under-resourced communities experience the highest exposure to air pollution while remaining underrepresented in research and policymaking. Xoli Fuyani of Black Girls Rising called for greater investment in community-centred approaches that place environmental justice at the heart of clean air action. A "Run for Clean Air" organized around the University of Pretoria, where participants carried portable air quality monitors, demonstrated how citizen science can make invisible pollution visible and strengthen public advocacy for healthier cities.

As delegates left Pretoria, there was little sense that the work had been completed. Instead, the forum reinforced how much remains to be done: strengthening regional cooperation, harmonizing standards, expanding access to open air quality data and ensuring that financing reaches the cities and communities where it is needed most. Ewan Botha, a Gauteng Member of the Executive Council, captured the regional dimension when he noted that air does not need a visa to enter South Africa, reminding delegates that the atmosphere shared by African countries demands solutions that are equally shared. The 2026 Africa Clean Air Forum will be remembered not for identifying the continent's air pollution problem—that case has already been made—but for marking a transition in how Africa responds to it. Whether those ambitions translate into cleaner skies will depend less on discovering new solutions than on the confidence and capital to scale the ones Africa already has.
