Where will you find the cleanest air in the world? Is India on the list?

Switzerland has a PM2.5 average of 7.2 µg/m³ and 60% of energy from clean sources. Though more densely populated at 219 people per km², it maintains clean air with strict controls and green transport.

Ireland uses around 37% clean energy with a PM2.5 average of 7.0 µg/m³. Its population density is higher than some others, but clean fuels and environmental laws help.

Australia’s air quality averages 6.9 µg/m³ in PM2.5. Although only 24% of energy is clean, its vast open spaces and natural parks help keep air fresh.

Sweden’s clean energy use is 84%, with a PM2.5 average of 6.5 µg/m³. It has strong environmental policies and many green areas to maintain air quality.

Estonia uses 65% clean energy with a PM2.5 average of 6.3 µg/m³. Its forests and small cities help keep pollution levels down.

Norway scores well, with 98% clean energy use and an average PM2.5 level of 6.1 µg/m³. Its population density is low, around 15 people per km², contributing to clean air.

Canada's air quality is excellent with a PM2.5 average of 5.8 µg/m³. About 66% of its energy comes from clean sources and vast wilderness areas help keep pollution low.

With an average PM2.5 of 5.4 µg/m³, New Zealand enjoys fresh air thanks to 82% clean energy use and low population density. Strong environmental rules also protect its natural landscapes.

Iceland uses nearly 100% clean energy, mostly geothermal and hydro power. Its very low population density of just 3 people per km² contributes to exceptionally clean air, even in cities.

Finland leads with an average PM2.5 level of just 4.9 µg/m³. About 75% of its energy comes from clean sources like wind and solar. Its low population density and many forests also help maintain fresh air everywhere.
