In our relentless pursuit of modernization and economic growth, we often overlook the price our planet and health pay. Air pollution is one of the most serious environmental issues, affecting millions of people worldwide. Here are 21 countries with the worst air quality.
Bangladesh
Bangladesh’s capital, Dhaka, is one of the most polluted cities on the planet. The city’s air quality declines due to emissions from several brick kilns, overflowing traffic, and industrial operations.
Mongolia
Ulaanbaatar, Mongolia’s capital, faces severe air pollution, particularly during the cold winter months. The main culprit is the use of coal in traditional stoves and power plants.
Afghanistan
Afghanistan’s capital, Kabul, battles significant air pollution. Unregulated industrial activity, vehicle emissions, and the widespread use of low-quality fuel for heating and cooking all contribute to the city’s poor air quality. And the lack of infrastructure and legal framework makes combating air pollution a challenging task.
Indonesia
Indonesia’s forests and vibrant cities face a unique air pollution challenge. Seasonal forest fires, which are often deliberately started to clear land for agriculture, emit large amounts of smoke, harming air quality throughout the region. And Jakarta, the capital, suffers from severe traffic pollution. While the government has made some strides towards reducing deforestation and promoting sustainable land use, urban air pollution remains a major issue.
Nepal
Kathmandu, Nepal’s capital, is located in a valley that traps pollution, making air quality a constant concern. Dust from building sites, vehicle emissions, and the use of low-quality fuels all contribute to the city’s pollution problem. While the government is working to enhance public transport and regulate construction operations, the geographic barriers make it a difficult battle.
Egypt
Cairo’s dense population, heavy traffic, and industrial activities release an abundance of pollutants into the air. And the burning of agricultural waste in surrounding areas adds to the problem.
Iran
Tehran, Iran’s capital, is regularly covered with haze, especially during the winter months, due to industrial pollutants and the city’s mountainous surroundings.
Saudi Arabia
Saudi Arabia is known for its vast deserts and oil wealth but faces air pollution issues as a result, particularly in cities like Riyadh and Jeddah. In addition to emissions from vehicles and industrial activities, the frequent dust storms also contribute to high particulate matter levels in the air.
Turkey
Istanbul, Turkey’s cultural and economic heart, struggles with air pollution from heavy traffic and coal burning for residential heating. The city’s narrow streets and crowded population worsen the problem, particularly during the colder months.
Thailand
Bangkok is notorious for its air pollution. The city’s traffic congestion and seasonal agricultural burning create a toxic mix of pollutants. The government has introduced measures to reduce vehicle emissions and promote green spaces, but Bangkok’s air quality remains a significant concern.
Vietnam
Vietnam’s major cities, Hanoi and Ho Chi Minh City are known for their chaotic traffic, which is subject to millions of motorbikes. These vehicles, mixed with industrial emissions and the burning of crop residues, contribute to severe air pollution. The government is encouraging the use of electric vehicles and improving public transport, but this transition will take time.
South Korea
South Korea, particularly its capital Seoul, experiences high levels of fine dust or particulate matter. The cause? Not only does South Korea have to battle with its own smog created by vehicle congestion and industrialization, but cross-border pollution from China.
Mexico
Mexico City is one of the world’s largest urban areas and is infamous for its smog. The city’s air pollution is caused by vehicle emissions, industrial operations, and the valley’s geology, which traps pollutants. Efforts to improve air quality include expanding the metro system, promoting cleaner fuels, and planting trees, but the city’s sheer size and population pose significant hurdles.
Nigeria
Lagos, Nigeria’s economic hub, faces severe air pollution. Lagos’ rapid expansion, driven by an increasing population and economic development, has overtaken its infrastructure. This means that traffic congestion, insufficient waste management, and unregulated industrial emissions are everyday occurrences. And the city’s informal waste disposal methods, such as rubbish burning, emit dangerous pollutants into the air, worsening air quality even more.
Russia
Moscow and other major Russian cities are still dealing with the remains of heavy industrialization. These industrial emissions contain particles, sulfur dioxide, and nitrogen oxides, all of which contribute to smog and acid rain. Vehicle emissions add another layer of pollution, with an increasing number of cars on the road, many of which operate on lower-quality fuels.
Peru
Lima, the bustling capital of Peru, faces significant air pollution due to vehicle emissions and industrial activities. But it’s not just the emissions from vehicles and factories. Lima’s rapid growth has resulted in substantial building operations, which have generated a lot of dust. Unpaved roads and building sites increase particulate matter in the air, making it harder to adequately manage air quality.
Chile
Santiago, Chile’s capital, suffers from severe air pollution, especially during winter when temperature inversions trap pollutants from vehicles, industries, and residential heating. During winter, many residents burn wood and other materials to keep warm. And the city’s location, nestled in a valley, worsens the problem by trapping these pollutants.
Colombia
Bogotá, Colombia’s capital, faces chronic air pollution issues due to heavy traffic and the burning of low-quality fuels for residential heating and cooking. Initiatives to improve public transportation and promote cleaner energy are in place, but progress is gradual.
India
India’s growth story is one of rapid industrialization, thriving cities, and a growing middle class. But progress comes at a high cost: thick, choking smog. Cities like Delhi, Mumbai, and Kolkata often find themselves under a blanket of haze. Who are the culprits? A mix of vehicle emissions, coal-fired power plants, and unregulated industrial growth. While the government is making efforts to improve air quality, such as promoting electric vehicles and enforcing higher pollution limits, the path is long and challenging.
China
China’s economic success has lifted millions out of poverty, but it has also resulted in some of the world’s worst air pollution. Beijing, Shanghai, and other megacities are infamous for their smoggy skies, which are mostly caused by coal-burning power plants and an increasing number of vehicles. The government has made substantial attempts to reduce pollution by closing aging plants and promoting renewable energy, but due to the size of the problem, progress has been gradual.
Pakistan
Pakistan’s urban centers, particularly Lahore and Karachi, are covered in smog for much of the year. The primary sources include coal-fired power plants, traffic, and a lack of green space. The government has begun focusing on renewable energy and enforcing stronger pollution laws.
