Context: Armoured and Specialised Vehicles of Armed/ Paramilitary Forces Exempted from BS-VI Emission Norms that will Come into Force in April 2020. 

Need:

1. The exemption has been granted because these vehicles operate in remote and inhospitable terrains with most challenging operational and environmental conditions.
2. Due to security challenges and requirements of specialized operations, the development of suitable engine compliant with the above norms would require considerable time.
3. It is difficult to maintain ideal transportation and storage conditions of fuel in these conditions.

Background:

Bharat Stage norms are the automotive emission norms which the automotive manufacturers have to comply to sell their vehicles in India.

These norms are applicable to all two wheelers, three wheelers, fourwheelers and construction equipment vehicles.

To curb growing menace of air pollution through the vehicles emission, the Government of India has decided to leapfrog from the exiting BS – IV norms to the BS- VI, thereby skipping the BS – V norms, and to implement the BS – VI norms with effect from 1st April 2020.

Only those vehicles will be sold and registered in India from 1st April 2020 onwards, which comply to these norms. The norms are stringent and at par with global standards.

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.

Why is it important to upgrade these norms?

1. Upgrading to stricter fuel standards helps tackle air pollution.
2. Global automakers are betting big on India as vehicle penetration is still low here, when compared to developed countries.
3. At the same time, cities such as Delhi are already being listed among those with the poorest air quality in the world.
4. 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.
5. 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.
