Sources of pollution

 

According to the Decision Support System for Delhi's Air Quality Management, transport is the largest contributor to pollution, accounting for 16.6 per cent, followed by Delhi and peripheral industries at 8.3 per cent. Residential sources contribute around 4 per cent, while construction activities add 2.2 per cent to the city’s pollution levels.

 

Delhi weather update

 

The India Meteorological Department (IMD) forecast partly cloudy skies with shallow to moderate fog during the morning hours on Friday.

 

Today, the temperatures in Delhi are expected to range between 7 to 9 degrees Celsius (minimum) and 23 to 25 degrees Celsius (maximum), remaining close to normal for this time of year. 

On Thursday, the maximum temperature settled at 25.6 degrees Celsius, 0.8 degrees Celsius below normal, while the minimum was 8.6 degrees Celsius, 1 degrees Celsius below the seasonal average.

 

A fresh, feeble Western Disturbance is expected to influence the Western Himalayan region from December 13, 2025 which may bring some relief from the worsening pollution levels.
