Gone are the days when air pollution was just an essay writing topic in inter-school competitions. Today, it’s a recognised fact that air quality is a serious concern and India is among the most affected geographies in the world. Various reports, including the latest Greenpeace and Air Visual 2018 Global City Ranking Report on PM2.5 concentration, reinforces that 22 out of 30 most polluted cities on the globe are located in India. According to the Lancet Report 2018, air pollution accounted for 12.4 lakh deaths in India. WHO’s annual report 2018 highlighted that air pollution is responsible for the premature death of seven million people each year, including 6 lakh children.
