Cleanliness is something that is often taken for granted, but it is actually a very important factor in the overall health of a city. In this article, we are going to take a look at the 10 cleanest cities on Earth, and why they rank so highly.

Methodology and Limitations

  1. To determine the cleanest cities in the world, 24/7 Wall St. reviewed various data sources, including the World Health Organization’s 2017 “World Health Report,” the Institute for Health Metrics and Evaluation’s 2018 “Global Burden of Disease Study,” and the United Nations Environment Programme’s 2017 “Eco-Indicators Cities Index.”
  2. In order to be considered for this list, a city had to have at least a “good” ranking on at least one of the three indexes. Cities that scored poorly on one index but had a good ranking on another were not included.
  3. The rankings are based on a city’s performance on environmental indicators, such as air quality and water availability.
  4. Each city was given a score from 1 to 100, with 100 representing the most environmentally friendly city in the world.
  5. The rankings are not based on economic indicators, such as GDP or population size.
  6. Each city is listed below with its corresponding score, its rank on each index, and the country in which it is located.

Ranking Criteria

To determine the cleanest cities on earth, a number of factors were considered. These included population density, air quality, public health, and city infrastructure. The cities that finished at the top of the list are all very diverse in terms of their culture and geography. However, they all share one common attribute: they are all very clean.
  1. Population Density
Cities with high population densities tend to be more congested and less clean. This is because there are more people fighting for limited resources, such as space and water. In comparison, cities with low population densities have more space to spread out and are therefore cleaner.
  1. Air Quality
Air quality is affected by many factors, including population density and industrial pollution. Cities with high population densities tend to have more industrial pollution, which contributes to poor air quality. City infrastructure also affects air quality; for example, poorly designed roads can cause smoggy skies.
  1. Public Health
Public health is important because it affects not only individual citizens but also the economy as a whole. A city that is unhealthy will have fewer people working and spending money in the city, which will have a negative effect on the economy.

How to Make Your City the Cleanest

There are a number of ways that you can make your city the cleanest on the planet. One of the most important things that you can do is to reduce the amount of waste that is produced. You can do this by recycling and composting, reducing the amount of garbage that is collected, and using less packaging. You can also promote green transportation. This means using public transportation, walking or biking, and carpooling. It also means using alternative energy sources, such as solar and wind power. You can also make your city more environmentally friendly by enforcing laws and regulations. This includes limiting the number of emissions that are released from businesses and homes and installing trash collection systems that are environmentally friendly.

Other factors that contribute to Canada’s cleanliness include its low population density, which helps to reduce dependency on resources; and its focus on public transportation, which helps to reduce pollution from cars. While Canada may be the cleanest country on earth, it’s not the only one. In fact, several other countries also make the list of the healthiest and most environmentally-friendly cities.

One of the cleanest cities on earth is Italy. Italy has maintained a high level of cleanliness for many years, and this has contributed to its status as one of the cleanest cities in the world. Italy’s high level of cleanliness is due to a number of factors. First, Italy has a very efficient public health system. This system ensures that all citizens receive healthcare and vaccinations and that outbreaks of disease are quickly quashed. Second, Italy has strong regulations regarding waste disposal. This means that all waste is properly disposed of, which reduces the amount of pollution that is produced. Another factor that contributes to Italy’s high level of cleanliness is its history as a maritime power. For centuries, Italy has been responsible for ferrying people and goods between different parts of the world. This has led to Italians being familiar with proper sanitation practices, and they have incorporated them into their everyday lives. All in all, Italy is one of the cleanest cities on earth, thanks to its efficient public health system, strong regulations regarding waste disposal, and history as a maritime power.


Australia has consistently ranked as one of the cleanest countries in the world. This is thanks in part to the country’s stringent environmental regulations and its high rate of recycling. One of the ways Australia promotes cleanliness is through its “Good Environmental Practice” program. This program requires businesses to meet certain environmental standards, such as using recycled materials or reducing energy consumption. Another way Australia promotes cleanliness is through its public transportation systems. All forms of public transportation in Australia are free, which makes it easier for people to get around town. This system also encourages people to use public transportation instead of driving their own cars. Overall, Australia is a highly clean and green country that does a lot to promote healthy living and environmental conservation.

Environmental Impact of a Clean City

One of the key factors that affect the quality of life in a city is the environment. A clean city has less environmental impact, which leads to a better quality of life for its citizens. To find the cleanest cities on earth, researchers from Forbes magazine conducted a study that looked at eight different factors: air quality, public transportation, green space, climate, pollution,cost of living, and health care. Out of the 8 cities studied, Vancouver was found to have the best air quality. The other seven cities were also ranked highly in terms of their environmental conditions. This indicates that making a city cleaner can have a positive impact on many aspects of life.

Economic Impact of a Clean City

A city that is clean is not just good for the environment, it also has a positive economic impact. A study by the World Economic Forum found that a city with a clean environment will have annual GDP growth of 1.5%. This is because a clean city attracts new businesses and investors, which in turn raises wages and creates new jobs. A clean city also has less crime. A study by Forbes found that cities with lower crime rates are more likely to be efficient and prosperous. The decreased reliance on police forces allows for better infrastructure and cleaner streets, which in turn encourages businesses to locate in the city. There are many benefits to having a clean city, and it is important that municipalities work to improve their environmental conditions. By doing so, they will not only benefit the environment but also their economy and citizens.
