2: Pakistan
Pakistan faces extreme air pollution, reducing life expectancy by 33 years on average. The country’s PM2.5 levels exceed WHO guidelines by 14 times, primarily due to industrial emissions and vehicle pollution.
Cities like Peshawar and Lahore report some of the highest pollution rates, severely impacting public health.
3: India
India struggles with severe air pollution, ranking fifth among the most polluted countries. Average PM2.5 levels in India are about 10 times higher than WHO guidelines, with cities like Begusarai reaching levels over 23 times higher.
Industrial emissions and vehicle exhaust are key contributors, impacting 1.3 billion people.
4: Tajikistan
Tajikistan ranks among the most polluted countries, with PM2.5 levels reaching about nine times higher than WHO guidelines.
Industrial emissions, dust storms, and vehicle pollution contribute significantly to this air quality crisis.
Cities like Dushanbe face severe health risks, impacting respiratory health for many residents. Immediate action is crucial to mitigate these dangers.
5: Burkina Faso
Burkina Faso ranks among the world’s most polluted countries, with average PM2.5 levels nine times higher than WHO guidelines.
Main pollution sources include Sahara dust, uncontrolled crop burning, and urban activities. These factors severely hamper public health, shortening life expectancy by approximately 20 years for the average resident.
6: Iraq
Iraq faces severe air pollution challenges, with PM2.5 levels often exceeding international guidelines. Industrial emissions, vehicle exhaust, and dust storms contribute significantly to its air quality crisis.
Urban areas, especially Baghdad, suffer health impacts, including respiratory diseases and reduced life expectancy.
Addressing pollution requires urgent government action and public awareness initiatives.
7: United Arab Emirates
The United Arab Emirates (UAE) grapples with alarming air pollution levels, primarily due to industrial emissions and vehicular traffic. PM2.5 levels often reach around 70.3 µg/m³, significantly exceeding WHO guidelines.
The government has initiated projects focused on renewable energy, regulating emissions, and promoting public transportation to combat this crisis effectively.
8: Nepal
Nepal ranks as the world’s third most polluted country, with PM2.5 levels significantly impacting public health. Life expectancy drops an alarming 34 years due to air pollution.
In the worst-affected districts, pollution shortens lives by up to 51 years, primarily from industrial and vehicular emissions. Addressing this crisis is essential.
9: Egypt
Egypt faces extreme air pollution, with PM2.5 levels typically surpassing WHO guidelines by over 10 times. Major contributors include industrial emissions, vehicle exhaust, and seasonal dust storms.
Urban areas like Cairo experience severe health impacts, leading to respiratory diseases and reduced life expectancy.
The government is working to improve air quality through stricter regulations and public awareness campaigns.
10: Democratic Republic of the Congo
Democratic Republic of the Congo (DRC) ranks as the most polluted country in Africa. Fine particulate air pollution, or PM2.5, shortens life expectancy by 29 years on average.
In highly polluted regions, residents can lose up to 44 years. Pollution mainly stems from industrial emissions, deforestation, and biomass burning, posing significant health risks.
11: Kuwait
Kuwait faces extreme air pollution, with PM2.5 levels significantly exceeding WHO guidelines. Industrial emissions, vehicular pollution, and sandstorms contribute to deteriorating air quality.
In response, Kuwait has launched initiatives focusing on renewable energy and stricter emission regulations to combat this pressing problem.
Public awareness campaigns are also essential for enhancing community engagement in environmental protection efforts.
12: Bahrain
Bahrain faces significant air pollution challenges, with PM2.5 levels regularly exceeding WHO guidelines. Industrial emissions, construction activities, and vehicular traffic primarily contribute to this crisis.
To combat pollution, Bahrain has introduced stricter regulations on emissions, promoted public transport initiatives, and increased green spaces to enhance air quality for its residents.
13: Qatar
Qatar ranks as the fourth most polluted country globally, with PM2.5 levels averaging about 49 µg/m³—far exceeding the WHO’s guideline of 5 µg/m³.
In areas like Umm Salal and Al Daayen, residents face a staggering life expectancy reduction of over 35 years due to this severe air pollution crisis.
14: Indonesia
Indonesia ranks as the ninth most polluted country globally, with life expectancy reduced by an average of 2 years due to air pollution.
Some regions experience even worse outcomes, losing over 25 years. PM2.5 levels in cities like Jakarta and Bandung frequently exceed WHO guidelines, impacting public health severely.
15: Rwanda
Rwanda faces significant air pollution challenges, primarily from industrial emissions and vehicle exhaust. It’s reported that fine particulate pollution shortens life expectancy by approximately 24 years for residents.
The government’s initiatives aim to reduce emissions, promoting cleaner technologies and improving public transportation to combat these alarming pollution levels.
16: Zimbabwe
Zimbabwe struggles with severe air pollution, primarily due to industrial emissions and deforestation. PM2.5 levels frequently exceed WHO guidelines, contributing to respiratory diseases.
The government is working to improve air quality through environmental regulations, promoting cleaner energy sources, and enhancing public awareness about pollution’s health risks.
17: Ghana
Ghana faces increasing air pollution challenges, prompting urgent action. The country recently hosted its National Dialogue on Clean Air, emphasizing the need for coordinated efforts.
It’s partnering with Denmark to transition from nonrenewable to renewable energy sources, aiming to implement innovative solutions that enhance air quality and public health.
18: Kyrgyzstan
Kyrgyzstan faces severe air pollution challenges, particularly in urban areas like Bishkek. PM2.5 levels often exceed WHO guidelines by more than 6 times.
Key contributors include coal burning for heating, vehicle emissions, and dust from construction.
