Causes Of Air Pollution

1. Motor vehicle emissions is main reason behind the air pollution in the city. Public transport vehicles are only available for 50% people of the city. So, most of the people rely on private transportation.

2. According to "Census 2012", 90% of the households use LPG for cooking, the remaining 10% uses wood, crop residue, cow dung, and coal for cooking. Burning of wood, cow dung causes a lots of smog in the air.

3. The Badarpur Thermal Power Station is another source of pollution in the city. Despite producing less than 8% of the city's electric power, it produces 80 to 90% of the particulate matter pollution from the electric power sector in Delhi.

4. Agricultural stubble burning also affects Delhi's air quality when crops are being harvested. City neighbour state Haryana produces a lots of stubble burning, which causes the city harmfully.
