Mandating ‘acceptable’ fuel to be used in NCR for air pollution control

Conclusions of EPCA’s investigation into quality of fuel being used in NCR; its pollution impact and recommended actions. It is well recognized that the quality of fuel used for combustion has a critical role in the quantum of pollution generated. It is for this reason India has moved from petrol/diesel with 10,000 ppm of Sulphur in 1996 to 50 ppm in 2010 (this will be extended nationwide in April 2017). The improvement in fuel quality then allows for effective pollution control devices to be installed. In the case of diesel vehicles, for instance, only when fuel has Sulphur below 10 ppm, can after-treatment pollution devices be effective. The quality of fuel used for industrial production is equally important in terms of its pollution impact.
