Factors of Delhi air pollution

Subject – Environment

Context – SC says urban factors, not stubble burning, to blame

Concept –

The Supreme Court said the “cat is out of the bag” to prove that urban factors like construction activity, industrial emission, vehicular exhaust and road dust are actually the major causes of pollution in the Capital and not stubble burning.
Farm fires in neighbouring Punjab, Haryana and Uttar Pradesh contribute only 10 percent to the pollution.
