Delhi Air Improves, GRAP-IV Lifted; High Court Questions Air Purifier GST

• CAQM lifted GRAP-IV restrictions in Delhi-NCR despite 'very poor' air in some areas.
• AQI improved to 271 ('poor') due to strong winds, but forecasts predict a potential rise.
• GRAP Stage I, II, and III measures will continue to be enforced.
• Delhi High Court urged GST Council to reduce 18% GST on air purifiers, citing citizens' right to clean air.
• Previous GRAP-IV banned BS-III petrol and BS-IV diesel vehicles, excluding essential services.

Why It Matters: Delhi lifts GRAP-IV as air improves, but Stage III remains; High Court pushes for lower air purifier GST.
