What are the main causes of Delhi's poor air quality this winter?

Vehicular emissions, including nitrogen dioxide and carbon monoxide, are significantly contributing to Delhi's poor air quality, alongside year-round local pollution sources.

Are smaller NCR towns experiencing worse pollution than Delhi?

Yes, several smaller NCR towns, such as Bahadurgarh, have recorded worse smog episodes and higher pollution intensities than Delhi during this period.

What solutions does the CSE propose for Delhi's air pollution crisis?

The CSE recommends deep structural changes in the vehicular sector, including electrification, vehicle scrappage, and improved public transport, as well as cleaner industrial fuels.

Delhi Air Suffocates: Vehicular Fumes Choke City

Toxic pollutants from vehicular emissions, specifically nitrogen dioxide and carbon monoxide, have seen a significant increase in Delhi during the early winter months of October and November. An analysis by the Centre for Science and Environment (CSE) indicates that even with a reduced impact from farm fires, the air quality remained poor, underscoring the persistent influence of local pollution sources throughout the year.

Emerging hotspots for pollution have been identified across Delhi, with several NCR towns experiencing smog episodes that were worse than those in the capital. Bahadurgarh, for instance, endured a 10-day smog episode with an average intensity higher than Delhi's, demonstrating that smaller towns are now facing equal or greater pollution pressure within a unified air-shed.

The CSE has called for comprehensive structural reforms, emphasizing vehicle electrification targets, scrappage of older vehicles, and enhanced public transport. Recommendations also include cleaner industrial fuels and stringent emission norms, alongside addressing legacy waste. Meanwhile, authorities report a significant decline in farm fires across Punjab and Haryana compared to previous years.
