NEW DELHI: To upgrade a BS-IV emission norm compliant diesel car to BS-VI compliant would cost a manufacturer just Rs 36,000 but such a vehicle would be 82% less polluting, amicus curiae Harish Salve told the Supreme Court on Wednesday.
This information negated the stand taken by the automobile industry, which had claimed before the SC during the last hearing that BS-VI norms were proposed to be enforced from 2024 and if advanced to 2020, it would force manufacturers to invest huge amounts in technology, making their business unviable.
Salve, in his detailed analysis submitted to the SC, tried to demolish the manufacturers' argument. Citing a private study, Salve said to upgrade a BS-IV compliant diesel car to conform to BS-V emission standards, the manufacturer would have to spend Rs 15,800.
BS-V norm did not involve any significant change in engine technology except for improvement in fuel automisation with injection pressure 1600-1900 bar, Salve said. Even a BS-VI compliant diesel car had BS-IV compliant engine technology, he added.
But an additional cost of Rs 20,280 would be incurred in making the car BS-VI compliant to improve injection pressure to 1800-2100 bar and fit diesel particulate filter for PM control and lean NOx trap, Salve said.
In petrol vehicles, upgrading a BS-IV car to make it BS-VI emission norm compliant would cost just Rs 1,200.
The benefits in terms of reduction in emission of pollutants by investing just Rs 36,000 in a diesel car was huge, Salve said. It would reduce PM emissions by 82% and NOx by 68%. In a petrol car, a Rs 1,200 investment in a car would reduce NOx emissions by 25%.
But making cars BS-VI compliant would be meaningless if the fuel supplied by government-owned oil companies continued to be BS-IV or BS-III standard, Salve said. And these oil companies stood to bear the brunt of anti-pollution measures.
"The capital investment estimated for refiners for fuel quality change to BS-IV all over the country is Rs 45,000 crore and to go to BS-V and BS-VI norm is Rs 35,000 crore," Salve said. Salve suggested leapfrogging of fuel norms from BS-IV to BS-VI by skipping BS-V.
"It will be more cost-effective to go to Euro-V/VI level at one go as the two step cost improvement could be avoided. It is clear that falling fuel prices is making it possible to make this investment at the earliest," he added.
Salve said the world was moving fast to Euro-VI fuel standard and by 2017, it is estimated that most countries, including Sri Lanka, would be using Euro-VI fuel. "Most of these countries are fuel and vehicle importing countries and so it could impact our competitiveness if India does not move to Euro-VI level,"he added.
