New Delhi: In the past few months, the Supreme Court and National Green Tribunal (NGT) have issued a series of directives to tackle air pollution. According to a study released by Delhi-based environmental think-tank Centre for Science and Environment on 15 December 2015, air pollution claims at least 10,000-30,000 lives a year in Delhi. It is one of the top 10 killers in the world and the fifth leading cause of death in India, said the study titled Body Burden 2015: State of India’s Health.
