Struggling with hefty emissions, the leap from standard Bharat Stage IV to VI is set to have a dramatic effect on India's vehicle emissions.
The change could potentialy reduce overall NOx emissions by 68%, with particulate matter from diesel engine cars down by 80% and 25% off NOx from petrol cars.
BS-IV emission compliance currently only extends to the national capital region and Northern India. However, BS-IV fuel quality and emission norms should cover the whole country by 1st April 2017.
SSV Ramakumar, executive director of Indian Oil Corp.’s R&D Centre, has pointed to the Global Burden of Disease database as a good reason for the dramatic move, with outdoor pollution the fifth largest killer in India.
The estimated cost of the regulations change to state-owned oil companies will be $4.3bn to upgrade refineries to meet BS-VI standards. Ramakumar believes the costs of moving from BS II to BS VI will have been approximately US$12bn between 2000 and the final changes in 2020.
