The Supreme Court has banned the sale and registration of motor vehicles conforming to the emission standard Bharat Stage-IV in the entire country from April 1, 2020

About BSES

*Bharat stage emission standards (BSES) are emission standards instituted by the Government of India to regulate the output of air pollutants from internal combustion engines and Spark-ignition engines equipment, including motor vehicles.
*The standards and the timeline for implementation are set by the Central Pollution Control Board under the Ministry of Environment & Forests and climate change.
*India has been following European (Euro) emission norms, although with a time lag of five years.
* The BS IV norms had been enforced across the country since April 2017.
* In 2016, the Centre had announced that the country would skip the BS-V norms altogether and adopt BS-VI norms by 2020. 
*Implementation of the intermediate BS-V standard was originally scheduled for 2019.

Difference between BS-IV and BS-VI:

*The main difference in standards between the existing BS-IV and the new BS-VI auto fuel norms is the presence of sulphur.
* The BS-VI fuel is estimated to bring around an 80 per cent reduction of sulphur, from 50 parts per million to 10 ppm.
*According to analysts, the emission of NOx (nitrogen oxides) from diesel cars is also expected to come down by nearly 70 per cent and 25 per cent from cars with petrol engines.
*SC quoted that India has the dubious distinction of having 15 out of the 20 most polluted cities in the world and thus such measure was necessary
*The problem of pollution is not limited to the NCR of Delhi but it is a problem which has engulfed the entire country especially the major cities.
