The National Green Tribunal (NGT) has called for an ‘auto census’ to take stock of the number of vehicles on the streets of National Capital Region. NGT last month asked all areas under NCR, spread across three states, to submit the details on the number of vehicles registered in their jurisdictions. Local authorities in Delhi, Noida, Ghaziabad, Gurgaon, Faridabad and Bahadurgarh were told to submit the number of vehicles registered in their respective areas, claimed industry sources. The authorities, it is claimed, were asked to categorise the vehicles into six categories that include autorickshaws, taxis, buses and trucks, apart from private cars and two-wheelers. The categories are expected to be further segregated into petrol and diesel vehicles. The tribunal is expected to use this information to conduct an auto census, following which it is likely to take decisions concerning air and noise pollution. The tribunal is known to have also asked the state representatives, to come up with the ideas to reduce pollution levels in their respective cities.
