What to study?
For Prelims and Mains: BS norms- key differences and significance, challenges in switching.
Context: NCR districts switch to Euro-VI grade fuels (BS-VI fuels). The supply of ultra-clean Euro-VI grade fuel (also known as Bharat Stage VI grade fuel) began in cities adjoining the National Capital Region (NCR) on April 1, 2019.
Delhi in April 2018 became the first city in the country to roll-out ultra-clean Bharat Stage VI (BS-VI) grade fuel, both petrol and diesel.
What are BS norms?
The BS — or Bharat Stage — emission standards are norms instituted by the government to regulate the output of air pollutants from internal combustion engine equipment, including motor vehicles. India has been following the European (Euro) emission norms, though with a time-lag of five years.
Difference between BS-IV and the new BS-VI:
The major difference in standards between the existing BS-IV and the new BS-VI auto fuel norms is the presence of sulphur. The newly introduced fuel is estimated to reduce the amount of sulphur released by 80%, from 50 parts per million to 10 ppm. As per the analysts, the emission of NOx (nitrogen oxides) from diesel cars is also expected to reduce by nearly 70% and 25% from cars with petrol engines.
Upgrading to stricter fuel standards helps tackle air pollution. Global automakers are betting big on India as vehicle penetration is still low here, when compared to developed countries. At the same time, cities such as Delhi are already being listed among those with the poorest air quality in the world. The national capital’s recent odd-even car experiment and judicial activism against the registration of big diesel cars shows that governments can no longer afford to relax on this front.
With other developing countries such as China having already upgraded to the equivalent of Euro V emission norms a while ago, India has been lagging behind. The experience of countries such as China and Malaysia shows that poor air quality can be bad for business. Therefore, these reforms can put India ahead in the race for investments too.
