Excessive air pollution and the unfavorable environmental situation in general is considered one of the main challenges facing the modern global world. The life expectancy of different countries, fertility rates, health and the general well-being of people depend on the solution of this problem. To varying degrees, but almost every state is taking a number of measures to maintain cleanliness and improve environmental conditions.

For example, in many developed countries the authorities closely monitor the proper disposal of garbage, and citizens shift to electric cars, ride bicycles to work or walk on foot on a mass scale. There are also more drastic measures taken by governments. For example, in Singapore the sale of cars is restricted, and the average cost of vehicles is at least four times higher than in the United States. This allows not only to unload the roads, but also to improve the environmental situation.

In short, different states have their own idea of "cleanliness" and, accordingly, methods of combating pollution. Much depends on the location and size of the country, the scale of industrial production and other factors. As a rule, the most favorable situation is observed in the richest countries of Europe and some other states of the world with a high standard of living, including Australia, New Zealand and Canada.

Based on current data from the Environmental Performance Index, developed by scientists at Yale and Columbia American University, let's highlight the cleanest countries in the world in 2021.

Note. The Environmental Performance Index (EPI) covers 180 countries assessed on 24 indicators in ten categories of environmental health and ecosystem vitality.


1. Switzerland
2. France
3. Denmark
4. Malta
5. Great Britain
6. Luxembourg
7. Austria
8. Ireland
9. Finland
10. Iceland




The most environmentally friendly country in the world in 2021 is Switzerland. There are a number of reasons why the state has a well-deserved first place in the ranking, and for more than one year. Switzerland has very clean and delicious water, fresh air, many mountains, lakes and green spaces. The local government for many years passes important laws aimed at maintaining the environmental situation at the highest level. Despite the fact that living in Switzerland is very expensive, hundreds of thousands of immigrants dream to move to this country permanently.



France is the most visited country in the world. Every year to enjoy the architectural monuments, the beauty of the French streets and other attractions come to 90 million tourists, which is almost 1.5 times the population of the country (65.3 million). The legislation of France, aimed at effective de-industrialization, economical use of natural resources and energy saving, contributes to improvement of ecological situation. The country has very fertile soil and clean air.



The third cleanest country on the planet is a small northern country - Denmark. It is a great place to work, study, do business and live comfortably. According to the official UN report World Happiness Report, which collected data from 156 countries in the world, Denmark is in second place in the list of the happiest countries in the world. Danes are carefully monitoring the cleanliness of the streets and mass use of bicycles, which can be rented almost everywhere. Especially in a city like Copenhagen.



Malta is an island state, located in southern Europe in the Mediterranean Sea near the coast of Italy (about 80 km). A very small country with a population of 441.5 thousand people. It is a very popular tourist destination with a lot of beautiful places and luxury resorts. Malta is a member of the European Union and offers a very comfortable environment. Not surprisingly, many wealthy foreigners tend to get citizenship of Malta. The air quality is very high and the natural environment is diverse.


Great Britain

The United Kingdom of Great Britain and Northern Ireland rounds out the top 5 cleanest countries in the world. It is a densely populated island state with a high level of industrial development, so the local government takes a number of necessary measures to protect the environment. Particular attention is paid to reducing dangerous carbon emissions and improving the quality of fresh water. Today, the British Nature Conservancy has about 5 million members. The quality of life in Britain is very high.

In conclusion, according to the above-mentioned Environmental Performance Index, Burundi, Bangladesh, DR Congo, India, Nepal, Madagascar, Haiti, Lesotho, Niger and the Central African Republic are among the most polluted countries in 2021. That is, predominantly the poorest countries in the world.
