Air Pollution in Asia
99 out of the 100 most air polluted cities in the world are from Asia. The UNEP reports that nearly 6.5 million people die due to poor air quality every year, out of which 70% of the deaths occur in Asia and the Pacific. According to the 2023 Air Quality Life Index report, countries such as Bangladesh, Nepal, Pakistan, and India account for more than 50% of the life years lost due to air pollution. South Asia is the most polluted subregion in Asia, where the average lifespan declined by 5.1 years. Bangladesh is the most air polluted country in Asia. Life expectancy declined by 6.8 years in Bangladesh, as of 2023.
In 2023, Asia dominated the countries with the worst air pollution in the world. According to the 2023 World Air Quality Report, East Asia showed a diverse outlook, with some countries experiencing an increase in PM2.5 concentration in 2023 while others facing a decline. Countries such as Japan, Taiwan, South Korea, and Hong Kong SAR surpassed the WHO’s target 2 of 15 μg/m³. Mongolia continued its downward trend in PM2.5 concentration and recorded a 25% decrease in its PM2.5 concentration. Hotan, China stands out as the most air polluted city in 2023, with an annual average particulate matter concentration of more than 87 µg/m3. Whereas, Ibigawa, Japan is the least polluted city in the region, as of 2023.
The air quality in Southeast Asia deteriorated, due to many countries in the region experiencing a rise in PM2.5 concentration. Indonesia appeared as the most air polluted country in the subregion. While Phillippines saw improvement in air quality in 2023, recording a 10% drop in its particulate matter concentration. Cambodia’s air quality worsened, with its PM2.5 concentration tripling in 2023. The top 4 countries with the worst air pollution in the world in 2023 are from Central and South Asia. The region also has the most number of air polluted cities, with the top 10 most air polluted cities from India and Pakistan. 31% of the region’s cities had 10 times higher particulate matter concertation, compared to the WHO limit.
Green Tech and Clean Energy Solutions for India’s Air Pollution Crisis
The third most air polluted country in Asia, India, has the most number of cities out of the 100 air polluted cities in the world in 2023. The country’s annual PM 2.5 concentration increased to 54.4 μg/m³ in 2023. Delhi, the National Capital Territory of India, witnessed a 10% increase in its PM 2.5 concentration, with a peak monthly average of 255 μg/m³. 66% of the country’s cities report annual averages higher than 35 μg/m³.
A startup in India, called Takachar, is working towards reducing the air pollution associated with stubble and crop residue burning. It develops small-scale and portable equipment that converts crop residue into bio-products, such as fertilizers, fuel, or activated carbons. Takachar claims that up to 100 million tons of carbon dioxide can be reduced every year, by providing price-competitive renewable biobased active carbon, as an alternative to fossil-based activated carbon. Stubble burning is one of the major causes of smog and air pollution in the country, especially in rural areas. The company provides processing of a diverse variety of crop and forest residues and converts them into bioproducts with a wide range of agricultural applications
Another major reason for air pollution is the emissions and PM2.5 released from the burning of fossil fuels for conventional energy production. Many corporations in India are providing clean energy solutions. Some of the prominent names in the market include Adani Green Energy Ltd (NSE:ADANIGREEN) and Suzlon Energy Ltd (NSE:SUZLON). Let’s discuss them below in detail.
Adani Green Energy Ltd (NSE:ADANIGREEN) is a leading renewable energy company in India. It develops and operates utility-scale grid-connected wind, solar, and hybrid renewable energy power generation plants. On April 3, the company announced that it has become the first corporation in India to have surpassed 10,000 MW of operational capacity. Its portfolio consists of 1,401 MW wind, 7,393 MW solar, and 2,140 hybrid capacity. The total operational portfolio of Adani Green Energy Ltd (NSE:ADANIGREEN) will be able to provide energy to over 5.8 million homes and avoid nearly 21 megatonnes of carbon dioxide emissions annually.
Suzlon Energy Ltd (NSE:SUZLON) is another major name in the renewable energy market in India. The company has a wind energy capacity of nearly 20.5 GW across 17 countries, with 14.5 GW of wind energy assets in India. On March 7, the company announced that it has won an order for developing a 72.45 MW wind power project for a Delhi-based independent renewable energy provider, Juniper Green Energy Private Limited. Suzlon Energy Ltd (NSE:SUZLON) will deploy 23 wind turbine generators with a hybrid lattice tubular (HLT) tower, along with a rated capacity of 3.15 MW each at Juniper’s site in Dwarka district, Gujrat.
Air pollution continues to affect millions of lives globally. Green technology initiatives are emerging as a strategic path to reduce GHG emissions and control air pollution.

Methodology
To compile our list of the 20 most air polluted cities in Asia, we consulted the IQ Air’s Air Quality Index (AQI) live ranking. We have ranked the cities in ascending order of their Air Quality Index, as of April 22. We have also mentioned the PM2.5 and other pollutant concentrations of the cities, where available. For cities with the same AQI, we have used their PM2.5 concentration to break the tie.
