Air Pollution

Cars not the biggest polluters


  1. According to a IIT Kanpur study, road dust contribute a far greater share of the city’s air pollution.
  2. Road dust contributed 56% of all PM10 pollution while it was 38% for PM2.5.
  3. It is relatively hard to tackle dust because of Delhi’s geographic location and propensity to dust from the Thar desert.
  4. Also, the winter air traps dust along with a host of other airborne pollutant.
  5. The lack of larger policy to contain road-side construction and the regular cleaning of roads is also a major cause.
