</p><p>&nbsp; The National Green Tribunal (NGT) has ordered Road Transport Office (RTO) of Delhi to cancel the registration of all the diesel vehicles over a decade old. The order is to be in effect immediately and NGT has also asked Delhi RTO to share data of the vehicles whose registration will be cancelled. In Delhi, already 15 years older diesel vehicles are banned.</p><p>&nbsp; Exact details regarding this decision is yet not known and have to wait until announced to get clear picture. One thing's definitely clear that car makers, both new and used, are going to have merry time following this decision, as hundreds of thousands of cars will be pulled off of Delhi roads and owners will be forced to get new car. So increase in demand in both new cars and used cars with an inclination towards petrol won’t come as surprise. Car manufacturers will be evaluating their strategy to gain from this and try to compensate the big set-back most of them had have suffered due to the earlier ruling to ban vehicles with diesel engines larger than 2000cc. Meanwhile many unsuccessful attempts had been made to overturn the ruling of ban of 2000cc and above diesel units. Though it's expected that new ruling would help car manufacturers make up for some of the earlier lost volumes.</p><p>&nbsp; The single largest doubt regarding this decision is its effectiveness to reduce pollution. But this decision seems to be lot more logical than the earlier ban as old vehicles without doubt are bigger polluters but yet NGT seems to be ignoring the studies showing that only diesel are not to be blamed for air pollution. Many other sources like industries, petrol vehicles, burning of materials in winters for heat and illegal vehicles running on kerosene and many others contribute significantly to pollute the air. This new ruling, like the earlier ones too comes with obvious loopholes, forcing one to doubt its effectiveness to actually curb pollution. As owners now get 2000cc and above diesel cars registered from nearby places where ban isn’t applicable and additionally vehicles from that region travel across Delhi frequently so drop in car numbers have been seen but has the pollution actually reduced?</p><p>&nbsp; Adding to it, many people could also opt for getting their 10 year old diesel cars registered in nearby places like: Noida or Gurgaon. That brings us to the irony that this new ruling which doesn’t seem to have the clarity to achieve its intended purpose – curb air-pollution! The possibility of such order being implemented elsewhere in the country (just like ban on sale of cars over 2000cc was executed in Kerala) might also be in the minds of existing car owners across the nation.</p><p></p>
