Bharat Stage norms or Bharat Stage Emission Standards were introduced by Central Government in 2000 to regulate the amount of emissions from motor vehicles.
The different norms are brought in accordance with the time line set by Central Pollution Control Board (CPCB) which functions under MoEF.
The Bharat Stage norms are based on EU norms to regulate pollution. Presently BS-IV emission standards were introduced for 13 major cities in April, 2010. BS-IV norms are expected to come into force by nation-wide by March 31, 2012.
Central Government has decided to implement BS-VI norms from April 1, 2020 in order to curb vehicular pollution.
Government will directly switch over to BS-VI emission norms from present BS-IV norms and skip BS-V stage.
Resistance by Industry:
Two major industries are resisting direct introduction of BS-VI norms:
- Oil refineries will need to invest substantially to upgrade the refining process. The shift from BS-IV to BS-VI demands approximately Rs. 50,000 crore – Rs. 80,000 crore from oil refineries.
- Automobile industries will also be required to make high investments to produce vehicles with lower emission levels.
