Pollution curbs under GRAP-4 revoked in Delhi-NCR as AQI falls to 271

Delhi AQI

The Delhi government on Wednesday revoked Stage 4 of the Graded Response Action Plan (GRAP) after air quality in the capital improved to the ‘poor’ category. According to an official statement, Delhi’s Air Quality Index (AQI) was recorded at 271 on December 24.

The Sub-Committee decided to withdraw GRAP Stage 4 restrictions after reviewing the prevailing conditions.

“The AQI of Delhi has shown significant improvement since last night owing to high winds and favourable meteorological conditions and has been recorded as 271 (‘poor’ category) on 24.12.2025. However, the air quality forecast provided by IMD/IITM suggests a likely increase in AQI in the coming days due to slower winds,” the statement said.

Restrictions under GRAP Stages I, II and III will continue to remain in force.

“Actions under Stage I, II and III of the extant GRAP shall, however, remain invoked and be implemented as per the modified GRAP dated 21.11.2025,” it added.
