Abstract:

Experts have attributed the post-Diwali decline in air quality in Delhi to polluting fireworks from revelers combined with crop burning, a change in wind direction, and motor vehicle emissions.The government has introduced several emergency measures, like the odd-even vehicle rationing program which started in Delhi, regulating the use of fireworks during Diwali, and stopping construction work when the air quality crosses critical thresholds.Despite recording very poor air, analysis suggested that Delhi's air quality index might have actually improved compared to the past few years. However, it is important to view these indicators through a wider lens to stay focused on the true extent of the problem, in order to complement a robust, long-term mitigation plan.
