Sri Ganganagar in Jajasthan was India's most polluted city in 2024, based on average annual PM10 concentrations of 236 micrograms per cubic meter of air (µg/m³). This was roughly four times higher than India's National Ambient Air Quality Standards (NAAQS) for PM10, and more than 15 times above World Health Organization air quality guidelines.PM10 is suspended coarse particulate matter with a diameter of 10 micrometers or less. It can come from various sources, including dust from roads and agriculture, smoke from wildfires, and industrial sources. Long-term exposure to PM10 can result in serious health impacts, such as asthma, heart failure, and cancer, as well as premature death.

Byrnihat was the most polluted city in India in 2024, with an average PM2.5 concentration of nearly 130 micrograms per cubic meter of air (μg/m³). This high level of pollution made the small industrial town on the Assam Meghalaya border the most polluted cities worldwide in 2024. Poor air quality across India India was the fifth-most polluted country in the world in 2024, with an average PM2.5 concentration of 50.6 μg/m³. That same year, the country's capital New Delhi was also the most polluted capital city in the world. Vehicle exhaust and wood burning are some of the main sources of particulate air pollution in India, together with soil, road and construction dust . Impacts of air pollution in India The severe air pollution in India can have detrimental health impacts on the country's population. Fine particle pollutants penetrate deeply in the lungs, causing respiratory problems and can even result in premature death. More than two million deaths are attibuted to air pollution in India every year.

According to a survey regarding the performance of Delhi Government as of January 2020, 40 percent of the respondents from India's capital city noticed no reduction in corruption in the last five years. However, 14 percent of respondents felt that corruption has increased in public offices under the current government in the recent years.

The city of Byrnihat in Meghalaya, India was the most polluted city in the world in 2024, with average annual PM2.5 concentration of nearly 130 micrograms per cubic meter of air (μg/m³). This was roughly 25 times above the WHO PM2.5 recommended guideline. More than half of the 25 most polluted cities in the world in 2024 were located in India, including New Delhi, which was the most polluted capital city in the world that year.

In 2024, Bangladesh's capital Dhaka had a pollution index score of ****, the highest among megacities in the Asia-Pacific region. In contrast, Japan's capital Tokyo had a pollution index score of **** that year. Megacities on course for growth The United Nations defines megacities as cities with over ten million inhabitants. The population living in megacities has doubled in size in the last twenty years and is expected to rise even more until 2035. Today, the Asia-Pacific region is home to the highest number of megacities, with China and India alone accounting for around half of all megacities worldwide. At the same time, only half of the population in Asia is living in cities. This figure is also expected to rise exponentially over the next years, especially with much of the younger population migrating to larger cities. The growth of megacities and their higher population densities bring along several environmental problems. Exposure to pollution in India The most populated cities in APAC are located in Japan, China and India. As seen above, India's capital also falls among the top three most polluted megacities in the region and ranks second among the most polluted capital cities worldwide with an average PM2.5 concentration. As one of the fastest emerging economies in the world, India's rapid urbanization and industrialization have led to high pollution rates in different areas. The volume of emissions from coal-fired power plants has led to electricity and heat accounting for the largest share of greenhouse gas emissions in India. The country is also among the nations with the highest population share exposed to hazardous concentrations of air pollution worldwide.

The datasets contains date- and state-wise historically compiled data on air quality (by pollution level) in rural and urban areas of India from the year 2015 , as measured by Central Pollution Board (CPCB) through its daily (24 hourly measurements, taken at 4 PM everyday) Air Quality Index (AQI) reports.

The CPCB measures air quality by continuous online monitoring of various pollutants such as Particulate Matter10 (PM10), Particulate Matter2.5 (PM2.5), Sulphur Dioxide (SO2), Nitrogen Oxide or Oxides of Nitrogen (NO2), Ozone (O3), Carbon Monoxide (CO), Ammonic (NH3) and Lead (Pb) and calculating their level of pollution in the ambient air. Based on the each pollutant load in the air and their associated health impacts, the CPCB calculates the overall Air Pollution in Air Quality Index (AQI) value and publishes the data. This AQI data is then used by CPCB to report the air quality status i.e good, satisfactory, moderate, poor, very poor and severe, etc. of a particular location and their related health impacts because of air pollution.

New Delhi was the most polluted city in India in 2024, based on an average air quality index (AQI) of 169. The seven most polluted cities in India in 2024 all had AQI levels above 150. An AQI between 151 and 200 is classified as unhealthy. Air pollution in India India was the third most polluted country in the world in 2023, behind only Bangladesh and Pakistan. The South Asian country recorded an average annual fine particulate matter (PM2.5) concentration of 54 micrograms per cubic meter of air (µg/m3) that year, more than 10 times above the World Health Organization’s recommended limit. Health effects of air pollution Exposure to air pollution can lead to a range of health issues, such as strokes, respiratory conditions, and cardiovascular disease. Air pollution is attributable to millions of premature deaths every year around the world, with India one of the most affected countries.

Cehnnai observed a 25 percent reduction in average annual PM2.5 levels between 2019 and 2024. In comparison, Delhi - the second most polluted city India - saw PM2.5 levels rise 10 percent during this period.

As per the results of a large scale survey conducted in 2019, the Indian cities of Indore was rated as the most livable city in terms of food and air. The national capital region of Delhi had the lowest rating for air quality of about 1.8 among all cities. The poor air quality index of the capital was due to the dangerous, dirty air that arises from a mix of weather conditions, urban emissions and rural smoke that converged over the region.
