The Centre’s air quality panel instructed to lift the ban after AQI in the capital dropped from 450+ to about 339 on November 6. GRAP Stage-IV was the most disruptive set of restrictions that can be imposed to disrupt public movement at large. However, protocols under GRAP Stage-II and Stage-III will still be observed to continue the improvement in air quality.
As per the commission, the improvement in Delhi’s AQI was largely due to favourable wind speeds and a drop in stubble burning in surrounding states such as Punjab. Delhi chief minister Arvind Kejriwal and Punjab chief minister Bhagwat Mann took responsibility for paddy burning induced pollution in the state on November 3, they promised to help curb the practice by 2023.
