According to an analysis by the Council on Energy, Environment and Water, a Delhi-based think tank, transportation contributes the most -- 18 to 39 percent -- to Delhi's air pollution. Road dust is the second largest source of air pollution in the city (18 to 38 percent), followed by industries (2 to 29 percent), thermal power plants (3 to 11 percent) and construction (8 percent).

An increase in farm fires in Punjab, Haryana and neighbouring regions of Pakistan is also going to impact the air quality in Delhi-NCR. NASA's satellite imagery showed a large cluster of fires near Amritsar and Firozpur in Punjab and Patiala, Ambala and Kaithal in Haryana.

With Delhi-NCR bracing for months of poor air quality, experts have warned that high levels of air pollution can aggravate the Covid-19 pandemic. Severe air pollution in Delhi is a year-round problem, which can be attributed to unfavourable meteorological conditions, farm fires in neighbouring regions and local sources of pollution. A green war room with a 10-member expert team has been set up at the Delhi Secretariat to monitor the steps being taken to deal with high levels of air pollution in winters.

The environment department has also taken stern action against project proponents at large construction and demolition sites flouting dust control norms. The government will also start the spraying of Pusa bio-decomposer solution in non-basmati rice fields in the national capital, on Tuesday. The solution, experts say, can turn the stubble into manure in 15 to 20 days and therefore, can prevent stubble burning. Starting October 15, stricter measures to fight air pollution will also come into force in Delhi and its neighbourhood as part of the Graded Response Action Plan, which was first implemented in Delhi-NCR in 2017.
