Delhi Faces Severe Air Pollution Crisis
Delhi and nearby areas are experiencing very bad air quality, which is harmful to health.
The air has tiny pollution particles called PM2.5 that are much higher than what is safe.
Schools have moved classes online, and the government has put emergency measures in place, but people say these steps are not enough.
Experts say that vehicles are a big part of the problem and that switching to electric cars and cleaner fuels is important.
Southern states like Puducherry have much cleaner air.
The problem is serious and needs stronger, long-term solutions.
Delhi's air quality remains in the 'very poor' to 'severe' category, with PM2.5 levels 20 times higher than WHO guidelines.
Emergency measures like work-from-home and construction bans are in place, but residents say they are insufficient.
Vehicular emissions contribute more than 40% of Delhi's particulate pollution, with nearly 1,800 new vehicles added daily.
Experts urge a shift to electric vehicles (EVs) and cleaner fuels to reduce pollution and improve air quality.
Southern states like Puducherry, Tamil Nadu, and Kerala have cleaner air, with Puducherry recording the lowest PM2.5 level at 25 micrograms per cubic metre.

A shift to electric vehicles (EVs) and cleaner fuels is essential for long-term pollution control.
Residents and Activists
The transition to EVs and cleaner fuels is too slow and needs immediate acceleration.
