SC asks govt to use statistical model of wind pattern to curb air pollution

The Supreme Court on Wednesday suggested the Centre and Commission for Air Quality Management to rely upon a statistical-based model on wind patterns to take advance measures to curb air pollution in Delhi-NCR before the situation deteriorates.

A Bench of Chief Justice of India NV Ramana, Justices DY Chandrachud, and Surya Kant told the Centre, "When the weather becomes severe then we take measures. These measures have to be taken in anticipation to stop pollution and this anticipation has to be based on a statistical model. This is the National Capital; imagine the signal we are sending to the world. You can stop these activities in the anticipation itself."

The Supreme Court said it will not close the air pollution case and give final orders.The Supreme Court said due to the seriousness of the issue it will continue to hear this matter and posted the case for the next hearing on November 29.

The Apex Court also asked them to continue the measures for controlling air pollution for the next two to three days. In the meantime, if the pollution level becomes 100, then some restrictions can be lifted.

They also asked Punjab, Haryana, and Uttar Pradesh Governments about any study to show how much stubble has been removed from these States and what emission control methods have been adopted.
