The banning of old vehicles is a welcome step in order to improve air quality in the capital but banning of new vehicles which comply with the latest emission norms will be counterproductive, Mahindra & Mahindra Executive Director Pawan Goenka said in a conference call. He said the National Green Tribunal (NGT) should look at data and do the calculation.

A still to be published report of IIT Kanpur mentions that passenger vehicles contribute 4 per cent of particulate matter in Delhi out of which about 85 per cent is contributed by vehicles which are vehicles prior to BSIV. So BSIV vehicles are contributing only 0.5 per cent to the total PM2.5 load in Delhi, Goenka said.

Is that the reason to ban new BS IV vehicles? he asked. While diesel vehicles emit more particulate matters, CNG propelled automobiles emit more NOx and petrol vehicles have
more carbon dioxide emissions, he said. In order to improve the air quality, it is unfair to
focus only on one fuel and why not ban all?, he asked. Expressing similar views, SIAM Director General Vishnu Mathur said: Auto industry is the soft target. In the past several years whatever courts have asked us to do, we have done that.

There is need for fleet modernization policy. We need to work on a BS norms led rational to look into this matter,Mathur said. Hyundai Motor India Senior Vice-President marketing and Sales Rakesh Srivastava said: Auto industry has already made plans to invest in diesel technology as per BSV emission norms to be implemented by 2019 and such decisions can negatively impact the industry.
