The Commission for Air Quality Management (CAQM) imposes Stage 1 measures under the Graded Response Action Plan (GRAP-I) across Delhi-NCR after local air quality falls into the “poor” category. Business Standard and Mint both report that once the region’s air quality reaches this threshold, CAQM activates restrictions designed for the first phase of the GRAP framework.

While both outlets confirm the trigger—air quality turning “poor”—they describe the response in the same general terms: implementation of Stage 1 restrictions across the Delhi-NCR region. The reports do not detail the specific measures in their provided summaries, but they align on the key point that CAQM’s decision follows the GRAP mechanism and marks the beginning of graded controls rather than later, more stringent stages.

Overall, the coverage indicates that Delhi-NCR’s worsening air quality leads CAQM to start Stage 1 GRAP enforcement immediately, signalling continued monitoring and the possibility of escalation if conditions deteriorate further.
