What can be achieved if you put your mind to it…

Why move to CNG?

The Taj Mahal was crumbling due to atmospheric pollution from industrial emissions in AgraHigh levels of pollution from Transport in Delhi and MumbaiNatural gas was available, there was no other practical option

“CNG is estimated to have a cancer potency 80 times less than Indian diesel vehicles and one CNG bus achieves emissions reductions equivalent to removing 85-94 cars from the road”

Diesel lobby very anti – quote from diesel advocate“It would be unrealistic to expect that ten thousand buses in the

city would ever ply on the roads using CNG as a fuel”

But what actually caused the move?

Supreme Court ordered all public transport vehicles to switch over to CNG on 1 April 2001

Buses, taxis, auto-rickshawsTransition allowed but only for <8 year old vehicles

The start – April fools day 2001
