One of the best and most enjoyable things that a person can do in life is to visit various cities and countries in the world. Traveling is something that can expand one’s view of the world exponentially. In every country, there are lots of places to discover and things to do. Those who love to travel sometimes create their rankings of the best places they have visited by using various criteria, such as beauty, diversity, and more. In this post, we are going to give you a ranking of the cleanest countries in the world.
Cleanliness does not only make a place look better, but it also helps in leading a healthier and longer life for the people. For instance, nations that have high air quality scores reduce the chances of their citizens being exposed to harmful particles, which also decreases the frequency of illnesses associated with air pollution, like respiratory or cardiovascular disease. Conversely, nations with high pollution levels have high rates of non-communicable diseases, which account for 72% of all fatalities and 16% of which are brought on by toxic pollution.
The Environmental Performance Index (EPI)
Before we move on to the rankings, let us first understand how countries are being ranked based on cleanliness. Researchers from Yale University and Columbia University partnered with the World Economic Forum to measure the cleanliness and environmental friendliness of 180 countries in the world. To be able to do this, they developed the Environmental Performance Index (EPI).
The EPI measures 32 performance indicators across 11 categories related to two overarching policy objectives, which are ecosystem vitality and environmental health. The categories involve air quality, sustainability, water and sanitation, and biodiversity and habitat. 
Among these, air quality is one of the most that affects the environmental metrics of a country’s EPI score. Based on the World Health Organization (WHO), air pollution is among the leading threats to public health, and it is now a global issue. Water and sanitation also have a great impact because a source of clean water is important for human development, the country’s economy, and the environment. Some of the other determining factors of a country’s EPI are forests, fisheries, use of heavy metals, climate and energy issues, and more. 
Following the tabulation of the results, the nations are ranked from cleanest to dirtiest. This allows countries to quickly assess the efficacy of their environmental policies and the degree to which their environmental objectives have been met. 
The Ten Cleanest Countries in the World
In 2022, there are two new entries on the world’s rankings of cleanest countries, which are Norway and Germany. Take a look at the infographic below to see the rankings of the ten cleanest countries in the world.
