Delhi pollution: AQI 478 triggers GRAP Stage-IV; hybrid school, WFH for offices.

• Delhi's Air Quality Index (AQI) has surpassed 400, reaching 478, prompting the implementation of Graded Response Action Plan (GRAP) Stage-IV.
• Schools for classes 9 and 11 will switch to a hybrid learning model (physical and online) due to severe pollution, while classes 10 and 12 will continue offline.
• GRAP Stage-IV measures include a ban on all construction activities and restrictions on non-essential/polluting trucks entering Delhi.
• Government and private offices are advised to implement a 50% work-from-home policy for employees to mitigate pollution impact.

Why It Matters: Delhi's severe pollution mandates hybrid schooling and 50% work-from-home for many.
