Air pollution in Kathmandu has become a major public health concern, especially during dry seasons when dust and emissions increase significantly.
Kathmandu Valley consistently ranks among the most polluted urban areas due to vehicle emissions, construction dust, and limited airflow caused by surrounding hills. The problem worsens in winter and pre-monsoon seasons.
Poor air quality affects respiratory health, especially among children and the elderly. The government has introduced measures like vehicle restrictions and monitoring systems, but enforcement remains a challenge.
Public awareness campaigns are also increasing, encouraging people to use masks and reduce pollution sources.
Long-term exposure to polluted air can lead to asthma, lung disease, and other health issues. Environmental degradation also affects tourism and overall quality of life in Kathmandu.
