The air we inhale sustains life itself, yet its purity often goes unnoticed. Worldwide, including in the diverse terrains of Africa, air pollution has emerged as a significant health threat. Each year, the World Health Organisation (WHO) reports a staggering 4.2 million premature deaths due to outdoor air pollution. In Africa, swift urbanisation, industrial growth, and the widespread use of fossil fuels have exacerbated this issue. However, amid this challenge, some African cities are shining examples, showcasing commendable efforts towards achieving cleaner air and a carbon-neutral environment.
In a recent evaluation by the WHO, several cities across Africa have shown significantly lower levels of carbon dioxide and notably superior air quality. These cities serve as inspiring models of sustainable practices and shared dedication towards preserving the environment.
Port Louis, Mauritius: Fostering Environmental Excellence
Port Louis, the capital of Mauritius, exemplifies the potential for environmental conservation within a small island nation. Recognised for its beautiful beaches and lively culture, the city maintains an annual mean PM2.5 level of 10 µg/m3, comfortably below the WHO-recommended standard. This accomplishment reflects Mauritius’ proactive measures in promoting renewable energy and reducing reliance on fossil fuels.
Victoria, Seychelles: A Refreshing Environment
Victoria, the capital city of the Seychelles, presents another success story, with a PM2.5 level slightly above the recommended threshold at 11 µg/m3. Despite this minor deviation, the city sets a remarkable standard compared to its other African counterparts.
Maun, Botswana: Guardianship for Environmental Preservation
Maun, situated in the heart of Botswana, emerges as a city fiercely protective of its natural beauty. Recording an annual mean PM2.5 level of 12 µg/m3, just above the recommended level, Maun advocates for sustainable living and renewable energy. Local figures like Dr. Raj Ramdenee, a respected environmentalist and professor, actively promote a greener and healthier future for their city.

Factors Influencing Air Quality in African Cities
Industrial activities, transportation, and weather patterns significantly impact air quality across African cities. Efforts to reduce emissions from industries and vehicles, along with initiatives promoting cleaner energy sources and sustainable transportation, are crucial steps towards achieving cleaner air.
Recognising air pollution as a pressing environmental issue in Africa, these cities stand as proof of the transformative power of collective action. Collaborative efforts among governments, businesses, and citizens signify a promising narrative towards a future with cleaner air prevailing. The journey towards a carbon-neutral Africa continues, driven by a steadfast determination to create a healthier and more sustainable continent for future generations.
