74IG0U0A Delhi's air was already toxic before Deepavali. Here's what a new study found A new analysis by the Centre for Science and Environment (CSE) has found that Delhi entered the Deepavali season with its worst pre-festival air quality in three years.

The report suggests that severe pollution levels were already present before Deepavali, indicating that Delhi's air quality crisis is driven by persistent local emission sources in addition to seasonal factors. While stubble-burning contributed to pollution levels, the analysis found that transport emissions accounted for the largest share of locally generated pollution.
