Delhi has now overtaken Beijing as the most polluted city in the world and over Diwali the air quality deteriorated to new lows. In this article, Payal Dey discusses how serious the problem has become, highlights the Delhi government’s lethargic response to the current crisis and outlines policy suggestions for controlling smog in the Indian capital.

This article captures the need for paying immediate attention for curbing air pollution, builds a case for a complete ban on firecrackers, fireworks and open fires, and recommends policy suggestions for controlling smog in the Indian capital.
