Bharat Stage emission norms in India

The deadline for pan-India rollout of BS III emission norms which was originally set for April 2010, is now delayed to October this year. This is because the public sector refiners could not meet the deadline and planned a staggered roll-out in different cities.

This staggered schedule does not augur well for the automobile manufacturers as it will be a problem in launching new vehicles with improved engines. Thus, a draft amendment in Central Motor Vehicles Rules, 1989 in March 2010 was made which exempts vehicles manufactured between 1 April, 2010 and 30 September, 2010 from following the fuel standard norms under BS III.

What are BS norms?

The implementation of the BS IV norms in 13 cities in April 2010 was one of the reasons for an increase in price of cars in April. This is because production of higher fuel-efficient vehicles require a upgradation of manufacturing facilities as well.

What are Bharat Stage emission standards?

Bharat Stage IV emission norms are emissions standards that focus on regulating pollutants released by automobiles (motor cars) and other powered vehicles. Since the year 2000, India started adopting European emission and fuel regulations for four-wheeled light and heavy-duty vehicles.

Since the year 2000, India started adopting European emission and fuel regulations for four-wheeled light-duty and for heavy-dc. India’s own emission regulations still apply to two- and three-wheelers.

Current requirement is that all transport vehicles carry a fitness certificate that is renewed each year after the first two years of new vehicle registration.

On October 6, 2003, the National Auto Fuel Policy has been announced, which envisages a phased program for introducing Euro 2 – 4 emission and fuel regulations by 2010. The implementation schedule of EU emission standards in India is summarized below:

Indian Emission Standards (4-Wheelers)
Standard Reference Date Region
India 2000 Euro 1 2000 Nationwide
Bharat Stage II Euro 2 2001 NCR*, Mumbai, Kolkata, Chennai
2003.04 NCR*, 10 Cities†
2005.04 Nationwide
Bharat Stage III Euro 3 2005.04 NCR*, 10 Cities†
2010.04 Nationwide
Bharat Stage IV Euro 4 2010.04 NCR*, 10 Cities†
* National Capital Region (Delhi)† Mumbai, Kolkata, Chennai, Bengaluru, Hyderabad, Ahmedabad, Pune, Surat, Kanpur and Agra

The above standards apply to all new 4-wheel vehicles sold and registered in the respective regions. In addition, the National Auto Fuel Policy introduces certain emission requirements for interstate buses with routes originating or terminating in Delhi or the other 10 cities.

For 2-and 3-wheelers, Bharat Stage II (Euro 2) will be applicable from April 1, 2005 and Stage III (Euro 3) standards would come in force preferably from April 1, 2008, but not later than April 1, 2010.
