GRAP-III : Delhi Scraps Pollution Control Measures, Details

The Commission for Air Quality Management (CAQM) has decided to roll back the curbs under the Graded Response Action Plan (GRAP), Stage III on January 17, 2025. The development comes after a marked improvement in Delhi's air quality levels. The decision was implemented after a review by the GRAP Sub-Committee. 

The air quality measures had initially been tightened on January 15, 2025  when Delhi's AQI breached the 350 mark.  

The committee observed an 'improvement' in the Air Quality Index (AQI) from "Severe" to “Very Poor” across a period of time.

Delhi's AQI Update

On January 16, 2025, Delhi's AQI was recorded at 302, well below the threshold of 350, prompting the revocation. In an order, the CAQM noted that favourable weather conditions, including strong wind speeds, have contributed to the sustained improvement. However, Stage-I and Stage-II measures under GRAP will remain in force to ensure continued air quality monitoring and prevent further deterioration.

The order reads, "AQI of Delhi has been continuously improving and has been recorded as "VervPoor" on l7.Ol.2025, which is about 61 AQI points below the benchmark as directed for by the Hon'ble Supreme Court for invoking Stage-III.", ANI reported.

GRAP-III : What Is Allowed?

"Construction and demolition sites that were issued closure orders for violations cannot resume operations without explicit permission," stated the official order from CAQM office.

The order also emphasised the importance of adhering to the citizen charter and maintaining vigilance, especially during the winter months when meteorological factors can quickly reverse air quality trends.

Actions under Stage-III were implemented as a precautionary measure, as per Supreme Court directions, to mitigate pollution spikes that could push the AQI above 400.

Despite the revocation of Stage-III actions, the CAQM urged citizens to actively participate in minimizing pollution through responsible practices. The Sub-Committee will continue to monitor air quality and forecasts from the Indian Meteorological Department (IMD) and the Indian Institute of Tropical Meteorology (IITM) for any required adjustments. 

GRAP-IV Scrapped Earlier

CAQM had earlier announced the revocation of Stage-IV measures of the Graded Response Action Plan (GRAP) for Delhi and the National Capital Region (NCR) following a notable improvement in air quality.

"The Sub-Committee decides to revoke with immediate effect, its orders dated 15.01.2025, for invoking actions under Stage-lV ('Severe+'Air Quality) of extant Schedule of GRAP," CAQM said.
