List of least-polluted cities by particulate matter concentration

From Wikipedia, the free encyclopedia

Below is a list of 526 cities sorted by their annual mean concentration of PM2.5 (μg/m3) in 2022.[1][2] By default the least polluted cities which have fewest particulates in the air come first. Click on the arrows next to the table's headers to have the most polluted cities ranked first.

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.
