Top Polluting Countries That Cause the Most Harm to Our Health and Environment

top polluting countries

The state of the environment directly affects our health and economic well-being. The reasons for pollution can be different. However, do you know that it is humans and the rapid development of technology that do the most harm to the environment?

According to reports by world-renowned organizations (WHO, Pure Earth, and others), about 91% of the population has to breathe polluted air. Air pollution is the cause of many diseases (non-infectious, cardiovascular, lung cancer). Already, about 4.5 million people die each year and if measures are not taken, the number of deaths will continue to grow. In this article, you will find out which countries pollute the most according to different criteria and possible solutions to the problem.

What Are Pollution and Its Most Dangerous Forms?

Pollution is the process by which contaminants, such as chemical waste or debris, enter the environment, resulting in adverse changes. The severity of environmental pollution by countries is determined by such factors:

  • the chemical nature;
  • the concentration;
  • the area affected;
  • the persistence.

There are a lot of forms of pollution but today we would like to drop your attention on forms that have been dangerous for the last couple of years.

Air Pollution

Air pollution occurs when gases, particulate matter, and biological molecules enter the atmosphere. Among the primary air pollutants is gaseous carbon monoxide from automobile exhaust gases or sulfur dioxide emitted from factories. The highest polluting countries are Bangladesh, Pakistan, and India.

Carbon Dioxide Is One of the Largest Polluters by Country

Carbon emissions harm climate change. Countries that cause the most pollution by carbon dioxide are China, the United States, and India. These countries have caused problems for their populations as well. For example, India suffers from a lack of drinking water. And excessive rainfall in the United States has become the cause of more than one new water over the past two years.

Water Pollution

Water pollution occurs due to the discharge of insufficiently treated wastewater into lakes, rivers, oceans, groundwater. Using contaminated water for drinking, irrigation and bathing can lead to illness or even death. The countries with the highest pollution are Somalia, Egypt, and Syria. The water resources of these countries have changed in temperature and color, indicating pollution.

Countries That Produce the Most Pollution

International organizations predict that emissions will increase by 130% by 2050. The most polluting countries have signed the Kyoto Protocol to reduce emissions, but as the practice has shown, this instrument is not enough.


China has a large export market and industrial production, so the emission of dioxide has long exceeded the established standards. The pollution rate is 30% from China. It should be admitted that China is trying to rectify the situation. For example, replace coal combustion with solar energy.

United States

The United States together with China are the largest polluting countries. The pollution rate is over 15% from the United States. Despite its leading role in the fight against climate change, the United States has not achieved great results.


14 cities in India are among the world’s most polluted cities. Burning fossil fuels results in a 7% level of environmental pollution.


Japan is a developed country, so it is not surprising that its industry has an impact on the environment. High fuel consumption and greenhouse gas emissions pollute the environment. The pollution rate is 4% from Russia.

It is difficult to say which country pollutes the most since any method of pollution leads to negative consequences. It depends on such factors as the economy, the technology of production, human resources, and many others.

The Worst Polluting Countries

If we compare the statistics of 2020 and 2021, the top polluting countries have not changed much. 92 countries were assessed to compare PM2.5 rates and identify the most polluting countries. Let’s take a look at some of them.


The level of PM2.5: 83.30.

The main field of activity of Bangladesh is brick production. Due to the high demand for brick production, the level of pollution may increase.


The level of PM2.5: 65.81.

Pollution is caused by waste incineration, exhaust gas, smoke from industries, and deforestation.


The level of PM2.5: 62.00.

The burning of coal and other biomass in stoves is the largest pollution source. Mongolian have serious health problems, for example, respiratory illnesses. Children’s lung function is reduced by 40%.


The level of PM2.5: 50.08.

Most cities in India have been heavily polluted due to a lack of forests, smoke from fires, and hazardous substances. If you open the list of the most polluted cities, then at least 20 will be Indian.

The collection of data on the state of the environment and the degree of pollution depends on the state officials. First of all, it is necessary to combine efforts and create a common base for monitoring the situation.

The public can also influence the level of environmental protection by supporting existing laws and creating new ones.

At an online conference on climate, which took place in December 2020, countries that cause the most pollution revised their positions and came to the following conclusions:

  • Pakistan is going to refuse to build new coal-fired power plants.
  • India will soon double its renewable energy plan.
  • China has pledged to increase the share of non-fossil fuels in primary energy consumption by 25% by 2030.

Thank you for reading this article! We hope it was interesting and expanded your knowledge of pollution! We will wait for you on the pages of our blog!
