The Commission for Air Quality Management (CAQM) in the National Capital Region and Adjoining Area, a statutory body tasked with devising pollution control strategies, has directed Delhi and NCR states to lift all emergency measures. These measures include restricting entry into Delhi to only CNG, electric, and BS VI-compliant vehicles from other states, with exemptions for essential services.

As part of Stage IV in GRAP, all medium and heavy goods vehicles not involved in essential services were prohibited in the capital.

As per the recent CAQM directive, all remaining restrictions from stages I, II, and III of GRAP, including the prohibition of non-essential construction work, mining, stone crushers, and diesel generators, will remain in effect.

The India Meteorological Department reported that Delhi recorded a minimum temperature of 11.5 degrees Celsius on Tuesday, slightly below the season’s average.
