New Delhi, November 14: The Air Quality Index (AQI) in Delhi on Tuesday improved to an average reading of 308, however at this level, the air quality remains “very poor”, CPCB data said.

On Tuesday morning, the toxic smog continued to envelope the national capital, with reduced visibility in some areas that led to the cancellation of many trains.

Officials said on Wednesday light rain is expected in the city, which might further intensify the fog but could clear the smog.

For about a week, Delhi has been experiencing dense smog, forcing the authorities to enforce stringent measures in the National Capital Region.

The Aam Aadi Party (AAP) government in Delhi, on Tuesday, filed a fresh review petition before National Green Tribunal in connection with odd-even policy.

The Kejriwal government requested the Green Panel to exempt two-wheelers and women drivers for one year or till 2,000 additional buses are engaged. It also requested the panel to direct the neighbouring state to start implementing the Odd-Even scheme.

A few hours after the NGT refused to exempt women and two-wheelers from the odd-even scheme and ordered that diesel vehicles over 10 years old be taken off the roads immediately, the AAP government filed the petition.

The NGT also asked the city government to identify the most polluted areas today itself and sprinkle water. It also allowed the non-polluting industries and those manufacturing essential goods to operate in the Delhi-National Capital Region.

The green panel also reportedly asked the government to come up with logical explanations for exemptions.

While hearing the government’s review petition, the tribunal asked, “Why can’t you (Delhi government) run ladies special buses to solve the problem of transport during the odd-even scheme.”

The AAP government had on Monday moved the NGT to modify it’s November 11 order refusing to exempt women and two-wheelers from the odd-even car rationing scheme to tackle pollution.
