Why curbing vehicular pollution is key to Delhi’s fight against foul air

Experts say that cutting down pollution from vehicles is essential for improving Delhi’s air quality. Transport emissions are one of the biggest local contributors to fine particulate pollution (PM2.5), especially in winter when weather traps smog in the city. Many vehicles on Delhi and the wider NCR roads are older and pollute much more than newer ones. Current pollution-under-control tests are not enough, and enforcement is weak. Experts suggest stronger policies, better public transport, more electric vehicles, and proper emission monitoring to reduce toxic air.
