Published on Jul 14, 2026 by Sara Ideas
Air pollution, a pressing global concern, is a significant issue in India, with severe implications for public health and the environment. Understanding the state-wise air pollution levels is crucial for targeted policy-making and public awareness. Let's delve into the current scenario, focusing on the top polluted states and key factors contributing to their poor air quality.
Risk Map
According to the World Health Organization (WHO), India is home to 14 of the world's 20 most polluted cities. The Air Quality Life Index (AQLI) estimates that air pollution reduces life expectancy in India by an average of 4.3 years. With this backdrop, let's explore the air pollution levels in India, state-wise.

According to the CPCB, AQI levels in Uttar Pradesh often exceed 300, indicating 'hazardous' air quality. During winter, the situation worsens due to stubble burning and temperature inversion.
Other Severely Polluted States
Following Uttar Pradesh, the states with severe air pollution issues are:
