Damning information obtained by Greenpeace India through online reports and Right to Information applications from State Pollution Control Boards across India, shows that none of the Indian cities comply with standards prescribed by the World Health Organisation (WHO) and very few cities in southern India comply to Central Pollution Control Board (CPCB) standards. The information was revealed in a report titled ‘Airpocalypse’ that assesses air quality in 168 cities across 24 states and union territories and pinpoints fossil fuels as one of the main culprits for the deteriorating air quality across the country. Air pollution is a national public health crisis as almost none of the cities have bothered to keep air pollution in check, making them unlivable. The top 20 most polluted cities have PM 10 levels between 268 µg/m3and 168 µg/m3 for the year 2015. While, Delhi tops the list with 268 µg/m3, it is followed closely by Ghaziabad, Allahabad, and Bareli in Uttar Pradesh; Faridabad in Haryana; Jharia in Jharkhand, Alwar in Rajasthan; Ranchi, Kusunda and Bastacola in Jharkhand; Kanpur in Uttar Pradesh, and Patna In Bihar; with PM10 levels ranging from 258 µg/m3to 200 µg/m3.
