According to a Greenpeace India report published on Wednesday, 1.2 million deaths take place every year due to air pollution in India and the national capital, Delhi tops the list of 20 most polluted cities in the country. The report also claims that it assessed 168 cities in the country and none of the cities complies with air quality standards prescribed by the World Health Organization; only a "few" cities in southern India comply with air quality standards prescribed by the Central Pollution Control Board (CPCB). The report pinpoints fossil fuels as one of the 'main culprits' for the deteriorating air quality across the country.
