A senior official of the CPCB told The Hindustan Times, “Pollution levels are shooting up primarily because of unfavourable meteorological conditions. First, the wind speed was recorded at zero during most of the time since Thursday. Second, when wind speed picked up, it was coming from the northwest direction, where stubble burning is going on.” On Friday, Delhi Environment Minister Imran Hussain requested the Union Environment Minister Harsh Vardhan, in a written letter, to direct neighbouring state such as Punjab, Haryana, Rajasthan and Uttar Pradesh to take effective action against stubble burning.
