While many countries struggle with poor air quality due to dense populations, industrialisation, and vehicular emissions, some are defying the trend with impressively clean air. The Air Quality Index (AQI) is a scale used to measure air pollution levels in a region. It ranges from 0 to 500, with lower numbers indicating cleaner air and higher numbers indicating more pollution. Breathing easy is a luxury many of us can only dream of, but some countries make it a reality with their pristine air quality. Do you know which nations will have the finest air quality in 2025? From Finland to Switzerland, let's take a look at the top 10 countries with the freshest air, which is based largely on the average PM2.5 levels, clean energy use, and population density.
