Delhi's air quality deteriorated rapidly on Saturday, prompting authorities to escalate from GRAP-3 to GRAP-4 emergency measures within hours. With the AQI rising to 441, officials have banned non-essential trucks, halted all construction, recommended online classes for students, and advised offices to implement 50% work-from-home policies. The CAQM attributes the crisis to unfavorable weather conditions rather than local emissions.
