Africa's air pollution crisis claims 1.1 million lives yearly—why cities must act now

Air pollution has become one of the most serious health threats in African cities. Each year, it causes around 1.1 million deaths across the continent—nearly double the global average rate. The crisis is reshaping respiratory health, with women and children bearing the worst effects indoors and urban residents facing dangerous outdoor conditions.

Many African cities record PM2.5 levels far above the World Health Organization’s safe limit of 5 micrograms per cubic metre. Major urban centres like Lagos, Nairobi, Accra, Cairo and Johannesburg are among the hardest hit. Transport alone accounts for roughly a third of PM2.5 emissions in several megacities, while industrial activities contribute between 11% and 37% in some areas.

Indoor air pollution adds to the problem, particularly for women and children who spend more time near cooking areas. Burning charcoal, firewood and kerosene releases harmful particles, worsening respiratory diseases. The combined effect of outdoor and indoor pollution has made air quality a defining public health challenge for the continent. With 155 deaths per 100,000 people attributed to pollution, Africa’s mortality rate is almost twice the global figure. Experts warn that without intervention, the situation will continue to escalate, affecting millions more in the coming years.

The scale of the problem demands urgent action to reduce emissions from transport, industry and household fuels. Without stronger measures, air pollution will keep driving high death rates and long-term health damage. Cities must now balance growth with cleaner air to protect their most vulnerable residents.
