Why did the CAQM lift Grap Stage 3 restrictions in Delhi?

The CAQM lifted Stage 3 restrictions, citing marginal improvements in AQI and forecasts indicating conditions would remain in the 'very poor' category, along with revised Grap norms.

What activities resumed in Delhi after Grap Stage 3 was revoked?

Construction activities, mining, older diesel vehicles (BS-IV diesel light motor vehicles), and hybrid school operations resumed after the revocation of Grap Stage 3 curbs.

Is Delhi's air quality improving?

Delhi Air Quality: Curbs Lifted Amid 'Very Poor' Air

The Commission for Air Quality Management (CAQM) has lifted Grap Stage 3 restrictions in Delhi, despite the air quality index (AQI) remaining in the 'very poor' category at 327. This move permits construction activities and the use of older diesel vehicles to resume on roads, marking the 21st consecutive day of hazardous air. The decision was made even as forecasts indicated persistently poor air quality and follows Supreme Court encouragement for more stringent pollution control measures.

Experts criticize the early revocation, stating that the AQI of 327 is not significantly different from higher readings and that winter months are critical for pollution. The CAQM's rationale pointed to marginal AQI improvements and the recent revision of Grap norms, but this appears disconnected from scientific data and citizen demands for stricter actions, including the formulation of Stages 5 and 6 of the Grap plan.

This decision lifts restrictions on private construction, mining, and older diesel vehicles, and ends the hybrid school mode and 50% work-from-home mandate. The revocation occurs amidst questions about the reliability of Delhi's air quality monitoring network, with reports of missing data during polluted hours. Environmental activists have strongly condemned the CAQM's move, advocating for its dismantling and the implementation of root-cause solutions.
