Delhi's EV Policy 2.0: tackling air pollution at source

Question (10 marks, ~150 words):

Tackling urban air pollution requires source control, not seasonal firefighting. Examine with reference to Delhi's EV Policy 2.0.

Contrast reactive GRAP with source control. Give shares: transport ~41% PM2.5, heavy vehicles ~60%, two-wheelers <5%. Cite health gains (~800 deaths, ~₹15,000 cr). Note livelihood/grid caveats. Way forward: heaviest first, just transition, charging + grid.
