Every year, Delhi and northern states battle hazardous air during the winter months of October to January due to plummeting temperatures, smoke, dust, low wind speed, vehicular emissions and crop stubble burning.

Raja Jehangir Anwar, a senior environment official, said the "biggest headache" causing the smog was the practice of burning crop waste, known as stubble, across the Indian border.

Farmers burn the remaining stubble of their harvested crops during the months of November and December in order to clear the fields to make way for more planting.
