Air pollution in India refers to the presence of harmful pollutants such as PM2.5, PM10, nitrogen dioxide, sulfur dioxide, and ozone in the atmosphere at levels that exceed safe limits. Major sources include vehicles, industries, construction dust, and biomass burning. The Air Quality Index (AQI) is used to measure and report air pollution levels across Indian cities.
GreenGlobe25 explains air pollution science, Air Quality Index (AQI), and environmental monitoring systems in India using clear, research-based insights.
Introduction
Air pollution is a major environmental and public health issue in India, especially in urban regions where AQI levels frequently exceed safe limits. Cities like Delhi and Kolkata often experience high pollution levels during winter due to a combination of emissions and weather conditions.
Understanding air pollution involves learning about its sources, the pollutants involved, how air quality is measured, and how pollution levels are reported using AQI systems.
This page provides a structured overview of air pollution in India and links to detailed guides that explain each concept in depth.

Why Understanding Air Pollution Matters
Air pollution affects public health, environmental quality, and economic productivity across India. High pollution levels are associated with respiratory diseases, cardiovascular conditions, and long-term health risks.
Understanding how air pollution works helps individuals interpret AQI data, recognize pollution sources, and better understand environmental conditions in their region.
Why GreenGlobe25 Exists
Air pollution data in India is widely available but often difficult to understand. Government monitoring systems provide large volumes of data, but interpreting that data requires basic knowledge of pollutants, AQI systems, and monitoring frameworks.
GreenGlobe25 simplifies air pollution science, AQI systems, and environmental monitoring into clear, structured explanations designed for Indian readers.
