India has secured a place among the top 10 most polluted countries globally, with New Delhi standing out as the capital city with the worst air quality. Data from IQAir, a Swiss air quality technology company, reveals India’s third position on this concerning list, highlighting the severity of the air pollution crisis.

Bangladesh has claimed the undesirable title of the world’s most polluted country, topping the list with an average PM2.5 concentration of 79.9 micrograms per cubic meter (mg/m3). Following closely behind is Pakistan, securing the second spot with an average PM2.5 concentration of 73.7 micrograms per cubic meter (mg/m3). These alarming statistics shed light on the severe air quality challenges faced by these nations, emphasizing the urgent need for comprehensive measures to address the escalating pollution levels and safeguard public health. The data, compiled by IQAir, serves as a stark reminder of the pressing environmental concerns affecting these regions.

India has been placed third on the list, reporting an average PM2.5 concentration of 54.4 micrograms per cubic meter (mg/m3). In contrast, French Polynesia stands as the least polluted country globally, boasting an average PM2.5 concentration of merely 3.2 micrograms per cubic meter (mg/m3). These contrasting figures highlight the significant disparities in air quality across different regions, underscoring the critical need for robust environmental policies and initiatives to combat air pollution and safeguard public health.

The issue of air pollution remains a critical concern worldwide, with several countries grappling with alarmingly high levels of particulate matter in the air. As per the latest data from IQAir, a Swiss air quality technology company, the following is the list of the world’s top 10 most polluted countries:

1. Bangladesh

2. Pakistan

3. India

4. Tajikistan

5. Burkina Faso

6. Iraq

7. United Arab Emirates

8. Nepal

9. Egypt

10. Democratic Republic of the Congo

This ranking sheds light on the severity of air pollution in these nations, with each facing unique challenges contributing to the deterioration of air quality. Among these countries, India occupies the third position on the list, highlighting the persistent struggle with significantly poor air quality.

India’s Air Pollution Challenges:

India’s battle against air pollution is multifaceted, encompassing a range of factors that contribute to the high levels of particulate matter, particularly PM2.5, in the air. Some of the key challenges faced by India include:

1. Crop Burning:

The practice of stubble burning in states like Punjab and Haryana, particularly after the harvest season, releases substantial amounts of smoke and particulate matter into the air. This seasonal phenomenon significantly contributes to the spike in air pollution levels in the northern regions of India.

2. Vehicle Emissions:

Rapid urbanization and a growing number of vehicles on the roads have led to increased emissions of pollutants such as nitrogen oxides (NOx) and particulate matter from vehicles. Cities like New Delhi, Mumbai, and Kolkata struggle with traffic congestion and the associated air pollution.

3. Industrial Activities:

Industrial growth and the presence of manufacturing units in urban areas contribute significantly to air pollution. Emissions from factories, power plants, and industrial processes release pollutants into the atmosphere, further exacerbating the problem.

4. Coal Burning:

The reliance on coal for energy generation and industrial purposes remains a significant contributor to air pollution in India. Coal-fired power plants emit pollutants such as sulfur dioxide (SO2), nitrogen oxides (NOx), and particulate matter, leading to poor air quality in surrounding areas.

5. Waste Burning:

The improper disposal of solid waste, including plastic, rubber, and other materials, through burning releases toxic pollutants into the air. Open burning of waste in landfills and dumpsites is a common practice in many parts of India, adding to the pollution burden.

6. Biomass Burning:

In rural areas, the use of biomass, such as wood, crop residues, and cow dung, for cooking and heating purposes is prevalent. The burning of biomass releases particulate matter and other harmful pollutants, contributing to indoor and outdoor air pollution.

Impact on Health and Environment:

The consequences of poor air quality are far-reaching, affecting the health and well-being of millions of people. Exposure to high levels of particulate matter is linked to respiratory illnesses such as asthma, bronchitis, and lung cancer. Additionally, air pollution has adverse effects on the environment, contributing to climate change, acid rain, and degradation of ecosystems.

Addressing the Crisis:

Efforts to combat air pollution in India require a comprehensive and multi-sectoral approach. Some of the measures that can be implemented include:

1. Promoting Clean Energy:

Encouraging the use of clean and renewable sources of energy, such as solar and wind power, can reduce dependence on fossil fuels and mitigate air pollution from coal-fired power plants.

2. Improving Public Transportation:

Investing in efficient and sustainable public transportation systems can help reduce the number of vehicles on the roads, thereby lowering emissions from transportation.

3. Strict Emission Standards:

Enforcing stringent emission norms for industries, vehicles, and power plants can limit the release of harmful pollutants into the atmosphere.

4. Waste Management:

Implementing effective waste management practices, including recycling and proper disposal of solid waste, can minimize the burning of waste and its associated air pollution.

5. Awareness and Education:

Raising public awareness about the health risks of air pollution and promoting sustainable practices can empower individuals to make informed choices for cleaner air.


India’s inclusion in the list of the world’s top 10 most polluted countries underscores the urgent need for decisive action to address this pressing environmental challenge. The complex nature of air pollution demands collaborative efforts from government authorities, industries, communities, and individuals alike. By implementing sustainable solutions and adopting cleaner practices, India can work towards ensuring a healthier environment for its citizens and future generations. The battle against air pollution is not just a matter of environmental protection but also a crucial step towards safeguarding public health and promoting sustainable development.
