Australia topped the list as the least polluted country in the world, with 7 cities in the top 25. Of the 25 least polluted cities in the world with the best air quality, Nordic countries (Finland, Sweden, Norway, Iceland, Estonia) dominated the rankings with some of the cleanest air in the world in 2022.
Finland has the cleanest air in the world
Air quality in Finland is the best in the world according to data released by the World Health Organisation, WHO. The level of airborne particles in Finland is on average 6 micrograms per cubic metre – the lowest level for any individual country.
5 concentrations of 76.9 micrograms per cubic meter. “Central and South Asia had some of the world's worst air quality and was home to 46 of the world's 50 most polluted cities,” it stated. The cleanest air was found in the South Pacific island nation of New Caledonia (3.8), while Finland had the lowest PM2.
Australia air quality is generally among some of the cleanest in the world, although the country is vulnerable to short-term extreme pollution spikes which occur due to bushfires and dust storms.
The world's cleanest air is just across the Bass Strait. It's in North-Western Tasmania on the Cape Grim Peninsula where you can find the cleanest air on the planet, according to a measuring station on the cape.
Of the 117 countries analysed, Australia was ranked ninth best country for air quality in the world, four places ahead of New Zealand. Canberra was judged fourth cleanest air of the 107 worldwide capital cities monitored.
The cleanest air in the world is in Zurich. The pollution status is determined on the basis of average levels of PM2. 5 measured over a period of 12 months. And this Swiss city obtained an annual value of 0.51 µg / m3, which makes it the lowest in the world.
The world's least polluted countries are all in Northern Europe: Sweden, Finland, Norway and Estonia had just 5.0-5.9µg/m³ last year. This is unsurprising with each country regularly having less than 8.0µg/m³ over the last three years. Despite having low levels of PM2.
Scientists believe they have identified the world's cleanest air, free from particles caused by human activity, located over the Southern Ocean, which surrounds Antarctica.
The top five countries or territories, ranked by annual average of fine particulate concentration weighted by population, are the U.S. Virgin Islands, New Caledonia, Puerto Rico, Cape Verde and Saba.
Tasmania has the cleanest air in the world, monitored by the Cape Grim Baseline Air Pollution Station. The lack of pollution is due to the position of Tasmania in the Southern Ocean, far from other landmasses.
5 levels in most polluted countries worldwide 2020-2021. Bangladesh had an average PM2. 5 concentration of 76.9 micrograms per cubic meter of air (µg/m3) in 2021, making it the most polluted country in the world.
Air quality in Finland is the best in the world according to data released by the World Health Organisation, WHO. The level of airborne particles in Finland is on average 6 micrograms per cubic metre – the lowest level for any individual country.
Nitrogen Dioxide
NO2 is the most harmful of these compounds and is generated from the combustion of fuel engines and industry. It can damage the human heart and lungs and it reduces atmospheric visibility at high concentrations.

Australia performs well in many dimensions of well-being relative to other countries in the Better Life Index. Australia outperforms the average in income, jobs, education, health, environmental quality, social connections, civic engagement and life satisfaction. These assessments are based on available selected data.
1. Adelaide. Adelaide is often described as Australia's most underrated and beautiful city, and it is not hard to see why once you have visited this gorgeous place. It is a cultural hub, home to an excellent dining culture, several museums and art galleries, as well as gorgeous scenery wherever you look.
