This morning, New Delhi was covered in thick smog as the air quality declined to the "very poor" level, with many regions experiencing "severe' pollution.

Before Diwali, the Supreme Court eased its previous complete ban on fireworks in the national capital, allowing the sale and use of green fireworks under certain conditions.

The Commission for Air Quality Management (CAQM) implemented Stage 2 of the Graded Response Action Plan (GRAP) in the National Capital Region on Sunday.

Reacting to Delhi's air quality, a resident told ANI,“It is the responsibility of everyone. If every individual takes responsibility, then the AQI level can be controlled. Nothing will happen just by the thinking of the government and agencies... There were clear orders to use green crackers, and if we can adhere to these rules, then we would be doing a good service to the society.”

Meanwhile, another resident added,“Pollution hasn't just been increasing today; it's been increasing for years. Everyone blames politicians, but the people themselves are like this... People aren't improving themselves. You'll get firecrackers, but it's up to you whether to burst them or not.”
