Most polluting countries in the world

air pollution

Global pollution is a pretty serious problem that needs to be tackled in a fundamental way. When we talk about the pollution produced by both countries, we mainly talk about air pollution. Although there are different types of pollution, air pollution is causing serious consequences worldwide, such as global warming and climate change. The most polluting countries in the world They are the ones that emit the most polluting gases into the atmosphere.

In this article we are going to tell you which are the countries that pollute the most and what consequences air pollution has for the environment.

The air pollution

factories that pollute

This is an issue that is no longer exclusive to environmental interests. It has become a part of everyone's daily life over the years. Air pollution is a widespread concern, and its solution is not in the hands of governments or multinationals, but everyone can contribute a grain of sand to stop these consequences. The most visible evidence of air pollution is the famous clouds of pollution that gather around urban centers and are harmful to health.

There are other forms of air pollution that are not easily detectable or visible, but also have deadly consequences for the health of living things and ecosystems. These pollutants are causing warming and catastrophic consequences for the planet. In our discovery of the root causes of air pollution, we see that over thousands of years of life on this planet, toxic emissions have been produced.

Toxic emissions are part of the life cycle, but within the natural range. In other words, pollution naturally does not significantly affect the composition or structure of ecosystems because it occurs spontaneously. It is part of the cycle and does not increase due to human activity. Among these emissions we find gases emitted during volcanic eruptions, but their effects were not permanent. However, with the advent of the Human Industrial Revolution and intensifying population growth, we are faced with a global landscape of air pollution.

Any air pollution refers to the presence of toxic elements produced by human activity.

Main consequences

countries that pollute more

As we all know, the consequences of air pollution are quite numerous. The first and most immediate is the increase and worsening of respiratory and cardiovascular diseases among people living in polluted urban centers. Others, near industrial sources, they release these toxic products into the atmosphere. Respiratory and cardiovascular diseases have increased substantially in all these areas.

It is estimated that about 3% of hospitalizations are caused by exacerbations of related diseases with the amount of pollutants in the atmosphere. The most polluted countries in the world are those with the highest concentrations of these gases and therefore the greatest impacts on health.

Another serious effect of air pollution is the well-known greenhouse effect. We must not confuse the greenhouse effect itself with its increase. The problem is not that there is a greenhouse effect (without it, life would not be as we know it), it is that it is increasing the effects of these gases. Some of the problems caused by air pollution are the destruction of ecosystems, large-scale activities, rising sea levels, disappearance of land, reproduction of insects, extinction of species, etc.

The most polluted country in the world

most polluting countries in the world and consequences

We know that each year more than 36 billion tons of carbon dioxide are emitted into the atmosphere. It is the main greenhouse gas responsible for climate change. The route of emission of this fuel is mainly due to polluting human activities. Nevertheless, only a few of the world's most polluting countries emit the vast majority of these gases. Arguably the most polluting countries in the world in recent years are China, the United States, India, Russia and Japan.

When we talk about CO2 emissions, we actually call it the primary gas, but it's also called the metric. When we already know the equivalent CO2 emissions, we can already know the carbon footprint of each state, although logically the pollution it produces is not everything, nor is CO2.

If we don't know, we should know that current levels of pollution haven't occurred in at least 3 million years without humans on Earth. It should also be remembered that at that time the Earth was going through a period of very active volcanism.

According to available data, we find that China accounts for 30% of total global emissions, while the United States accounts for 14%. Let's analyze what is the ranking of the most polluted countries in the world:

  • China, with more than 10.065 million tons of carbon dioxide emissions
  • United States, 5.416 GtCO2
  • India, with 2.654 GtCO2 of emissions
  • Russia, with 1.711 million tons of CO2 emissions
  • Japan, 1.162 GtCO2
  • Germany, 759 million tons of CO2
  • Iran, 720 million tons of CO2
  • South Korea, 659 million tons of CO2
  • Saudi Arabia, 621 MtCO2
  • Indonesia, 615 MtCO2

Bangladesh entered the ranking of the most polluted countries in the world for its high pollution status. Its air quality is very low relative to permitted levels. An average of 97,10 polluting particles has been reached. This amount is due in part to the more than 166 million people living in Bangladesh are responsible for the massive emissions. It is in recent years that the country's industrial sector has grown exponentially. There are many factories, especially textile factories, that are producing large amounts of greenhouse gas emissions.

Saudi Arabia

The main source of Saudi Arabia's economy is oil extraction. This is a huge source of income and has become one of their most serious problems. It is the extraction of oil that not only produces economic benefits, but also emits a large amount of polluting gases. fossil fuel emissions They are more toxic and harmful to health.


India has also entered the ranks of the most polluting countries in the world with high industrial growth. Not only does it overgrow in industry, but it also misuses chemical fertilizers. This incorrect use of fertilizers has contaminated all the fertile lands and aquifers that store water.


It can be said that China is one of the leading countries in the world economy. However, it is also among the most polluted countries in the world. It was she who introduced new awareness and operational policies for measures to prevent and control environmental pollution. Nevertheless, big cities have a layer of air pollution so thick that you can barely see the sun. China's carbon dioxide emissions continue to double those of other major countries like the United States.


When you think of the most polluted country in the world, you probably don't think of this country. Thus, as in other countries such as India and Saudi Arabia, the industrialization of large start-ups is expanding rapidly. This industrial development leads to excess greenhouse gas emissions. Egypt may have reached levels of contamination, a total of 20 times higher than allowed.


Brazil is one of the developing countries with a prosperous economy. Unfortunately, this economic development is associated with a low awareness of caring for the environment. This low level of concentration means that there is also little action by the government. All of this adds up to the massive deforestation suffered by one of the main lungs of the planet, the Amazon. It not only increases the amount of polluting gas, but also decreases the absorption of carbon dioxide by plants.

I hope that with this information you can learn more about the most polluting countries in the world and the most polluted.
