Overview

  • CAQM revoked Stage-IV restrictions on December 24 after AQI improved from ‘severe’ to poor/very poor, while Stage I–III measures remain in effect.
  • Delhi will keep enforcing ‘No PUC, No Fuel’; inspections found irregularities at PUC centres, with 12 suspended and comprehensive verification ordered.
  • Air quality eased from a 24-hour average AQI of about 412 on Tuesday to 336–349 on Wednesday morning, with CAQM later noting 271 as winds dispersed pollutants.
  • The Delhi Cabinet approved Rs 100 crore to rejuvenate water bodies, cleared a zero-waste e-waste park at Holambi Kalan, and moved to expand automated vehicle testing and shift bus operations to DTC next fiscal.
  • Authorities reported action against more than 800 polluting industrial units, and IMD/IITM projections caution that slower winds could quickly erode the weather-driven gains.
