India has one of the fastest growing economies in the world and air pollution is one of the challenges associated with this growth and development. Of the world’s 30 cities with the worst air pollution, 21 are in India. The capital, New Delhi, has the poorest air quality among capital cities globally. Concentrations of particulate matter (PM2.5) in New Delhi are nearly 10 times higher than the World Health Organization guidelines.
