The 5 Cleanest Cities in the World


I welcome you to the five cleanest cities in the world. In them there is high-quality drinking water, pollution and traffic congestion are low and efficient waste management shines. We have a lot to learn from them.

While in most of the planet the air is becoming unbreathable, the rates of CO2 or the amount of garbage are a cause of high concern among its inhabitants and pollution causes anticipated deaths and hundreds of diseases, some cities can be proud of your level of cleanliness.

If we recently told you which are the seven most polluted cities in the world today it is the turn of the five cleanest. The classification is based on the Mercer Global Financial index, for which five factors were used: water availability and portability, waste management, quality of wastewater systems, air pollution and traffic congestion.

These are enclaves with powerful urban transport infrastructure, strict regulations for emissions, efficient systems for sanitation and waste management, sustainable housing and many more. They complete the classification of the ten cleanest Copenhagen, Wellington, Helsinki, Oslo and Freiburg.

Kobe (Japan)

One of the largest cities in Japan, Kobe, despite being occupied with a population of more than 1.5 million, is the fifth cleanest city in the world. A strong sense of responsibility embedded within the citizens encourages the creation of a waste-free environment, supported by a modern waste disposal system and a high level of recycling.


With a population of more than 5.6 million people, Singapore is not only one of the busiest, most expensive and innovative cities in the world, but also one of the cleanest. One of the secrets is that strict laws are applied to maintain cleanliness, regardless of whether the citizen is local or foreign. For example, high fines are imposed for polluting, it is forbidden to cut trees in protected areas and even chewing gum on public roads is not allowed.

Honolulu (Hawaii)

Known as the Pearl of Hawaii, the tropical paradise of Honolulu ranks 3 out of the 5 cleanest cities in the world. The lack of polluting industries or abundant vegetation in this sparsely populated remote island is some reasons behind its high levels of cleanliness. Since tourism is massive in this island city, maintenance and beautification are of the highest priority. Therefore, there is zero tolerance for garbage.

Adelaide (Australia)

The runner-up in the list of the 5 cleanest cities in the world is the capital of South Australia, Adelaide. With numerous financial institutions, Adelaide is of vital importance to the Australian economy. Its excellent waste management system stands out: approximately 85% of its waste is recycled.

Calgary (Canada)

Calgary, the industrial center of Canada, leads the list of the cleanest cities in the world. For this, it focused on optimizing and improving the following points that affect the environment: consumption capacity and water availability, air pollution, traffic congestion, sewage systems, waste disposal, and recycling.
