Below is a list of cities with the annual mean concentration of PM2.5 lower than 10 μg/m3 in 2022.
Please note that constraints exist in this type of lists. For instance, some places like Africa and South America lack air pollution reporting tools, so their pollution levels are probably not reflected in this list. Moreover, many cities from a certain country are featured in the list may only mean that they have large and wide air pollution monitoring networks, which may or may not be an indicator of heavy pollution.
