Ghana’s air quality improves for the first time since 2021; country places 11th in Africa – IQAir 2025 report

For the first time in five years, Ghana's air is getting cleaner. The IQAir 2025 World Air Quality Report, which tracks fine particle pollution, known as PM2.5, across 143 countries, territories and regions, recorded Ghana's national annual average at 21.3 micrograms per cubic metre (µg/m³). That is the country's lowest reading since IQAir began consistently tracking it, and a sharp reversal from 2024's figure of 35.8 µg/m³, a drop of more than 40% in a single year. The improvement moves Ghana from 8th most polluted country in Africa in 2024 to 11th in 2025, its best continental ranking in five years.
