Factors to determine the cleanest cities in the world

To be a clean city, you must address the issues that can contribute to filthy living circumstances and, as a result, ill-health. This primarily implies that garbage management must be well-organized, and the city must have a functioning waste system. Furthermore, transportation infrastructure has an effect on air quality and sanitation.

The cleanliness of a city is mostly determined by pollution. Pollution occurs when toxins are released into the air or environment, resulting in negative consequences. Air pollution causes lung cancer, cardiovascular illness, chronic obstructive pulmonary disease, and other major health conditions, which harm both the environment and the human body.


Another reason why this city could be dubbed “the cleanest” is that public transportation operates without emitting any pollution from Monday to Friday, owing to hydrogen fuel cell buses, which are among the first in Germany.

Cities all across the world suffer from varying degrees of pollution due to a variety of circumstances. Cities have been working on green initiatives for numerous years in order to introduce greener modes of transportation and processes and reduce pollution levels. In the United States, Congress implemented multiple Clean Air Acts in an effort to enforce stronger pollution restrictions, which resulted in significant reductions in pollution levels such as carbon dioxide and particle emissions.

Best Life looked at 200 of the world’s most populous cities to see which ones were the cleanest. Air pollution levels (both PM10 and PM2.5), Mercer’s quality of life ranking, the country’s Environmental Performance Index, and if the city appeared in Monocle’s Quality of Life survey were all factored into the analysis. Mercer and Monocle do not rank all of the cities on the list.
