MUMBAI/NEW DELHI: A day after the Delhi High Court said living in the city was like 'living in a gas chamber', the Delhi government in a unique move mandated vehicles with odd and even numbers to be allowed to run only on alternate days to curb pollution.A move, which the chairman of Maruti Suzuki, R C Bhargava says has no logic. He asked if the Delhi Government administration is aware of 'who are the contributors' to this pollution, before deciding the move.Starting 1st January of 2016, if vehicles with registration number ending with an odd number can be driven one day, only those ending with an even number can be brought out the next day. This will not apply to public vehicles, CNG driven buses, taxis and auto-rickshaws but will cover vehicles entering Delhi from other states too. The Delhi Government ordered this move in an emergency meeting on Friday.Bhargava told ET, "I am not sure, if Delhi administration understands the full logic, once they understand it, they may change the decision. Because cars become symbol of luxury or rich man’s product, it is one of the easiest to ban, because of its greater appeal."Explaining further Bhargava said the Delhi government needs to first look at who is polluting. The major pollution in Delhi is the particulate matter 2.5 PM and there is virtually no emission from petrol cars, he says, there are lots of other sources of pollution like -- construction activity, waste disposal and burning of waste from Punjab and Haryana, Desert storm from Rajasthan, diesel trucks passing through Delhi etc."what is being done to address them?, " the chairman of largest car maker asked, who has been a resident of National Capital Region for decades.The government said it hopes to reduce vehicular pollution in the union territory to a half. A joint meeting of traffic police, transport department and Municipal Corporation of Delhi will be called shortly to prepare the roll out of this executive order.To be sure, cities like Beijing, Singapore and London have had curbs -- like odd or even number vehicle allowed every alternate day and in some select places even an additional surcharge is levied to ply the vehicles in city central.Experts say, the move if implemented, could result into people buying two cars, one with an odd number and other with even number. It could also spur demand for cab aggregators Uber and Ola to meet the people’s transport need – and they may also be compelled to build their fleetVishnu Mathur, the secretary general of industry body, the Society of Indian Automobile Manufacturers Association or SIAM says these things need to be tried out - other countries have tried it and it has helped them.Mathur says this move could give impetus to public transport infrastructure. Which, industry players see as a big challenge currently. However he asserts that the current air quality in Delhi is not a factor of vehicle alone, everyone feels that reducing the number of vehicles could solve the problem, he observed.Sighting a report released by ICAP - Ministry of Environment and Forest, in 2011, only 8% of pollution was contributed by vehicles, this may have grown marginally by now, says Mathur."The fact is pollution created by bio mass, construction activity, Diwali crackers, farmers burning field and dust coming from the desert are major contributors. All this pollution tend to get trapped in the lower stratosphere due to adverse weather condition in the winter between September to December,” said Mathur“I fear, controlling the number of vehicles on road may not improve the air-quality, which is the primary objective, this has to be thought through in a holistic manner," he added.Experts say, the last 15 years data has shown that the pollution from January to August - usually comes down, it is only during the winters due to the adverse cold condition, between September to December, ambient atmosphere is the most polluted.Gaurav Vangaal, sr analyst for forecasting at IHS Automotive says, while the motive is good, the way of achieving is flawed."Auto industry alone is not responsible for pollution. Containing pollution in city like Delhi is for sure a dire need, but there has to be holistic approach keeping in mind interests of public and industry at large. Decisions can’t be taken overnight and changed overnight, there has to be a road map. Consumer paid taxes on their vehicle to government to ply on roads not to be parked at homes," added Vangaal.A view mirrored by Rakesh Srivastava, Sr VP, sales and marketing at Hyundai Motor India who says environmental challenges needs to be addressed with a long term, pragmatic & systematic solution worked out by involving all stake holders.He says scraping of older unfit vehicles is an appropriate fix to solve the emission as well as safety problems."Implementation of the Government directive would be a big challenge as it would need full cooperation of public supported by well organised public transport system offering safety, convenience & comfort to motivate people to use it," added Srivastava.
