The 100 most polluted cities in the world are in Asia – and 83 of them are in just one country

A recent report reveals that the vast majority of the world's most air-polluted cities are in Southeast Asia. Hong Kong has a key role in this problem, according to a CNN report.

The main building

In 2023, the latest air quality report by IQAir shows that 83 of the 100 most polluted cities are in India. This air quality crisis is a global concern, with public health consequences affecting billions of people worldwide.

The impact of the climate crisis

The climate crisis plays a central role in this problem, worsening air pollution levels. For example, fine PM2.5 particles, which come from burning fuels and fires, are linked to many serious diseases such as asthma and cancer.

Global impact

Air pollution kills millions of people every year, compounded by the combined effects of indoor and outdoor air pollution. This situation is exacerbated by climate change, which is increasing the frequency and intensity of fires and pollen, which exacerbates health issues.

Challenges and perspectives

Although there are some efforts to improve the situation, such as China's clean air policies, the challenges remain great and a global commitment is required to reduce air pollution and protect public health.

This report highlights a dire need for immediate and long-term action to address this important global problem.
